Breaking News!

Can You Handle a 44 Magnum?

Nallin Racing is hot and heavy into developing a new high performance big bore kit for the Blast P3. The kit will provide a whopping 720 cc displacement, an increase of 228 cc's over the stock 492 cc thumper. Be advised however, that with the 44 Magnum high performance big bore kit fitted, a mild mannered Buell Blast engine will no longer be a thumper. Rather, the P3 powerplant will be transformed into an earth pounding, fire breathing, pile driver!

Brian Nallin (formerly) of Nallin Racing (now at Revolution Performance) has dubbed the new mongo big bore the "44 Magnum" after the fact that it displaces 44 cubic inches.

Bore and stroke are squarely balanced at 3-13/16" each. As such, the 44 Magnum will be capable of reliably revving to 7,500 rpm while laying down well over 70 hp worth of thrust to any surface willing to accept it.

But what about power band you ask? It will be corn fed, grade "A" BEEFY. It has to be; Nallin Racing will be taking the engine to the track, fielding a 44 Magnum powered dirt tracker in the Pace Open Class series. You can bet the engine will be reliable as well as a VERY strong performer.

Folks, this is comparable in power to the stock pre-Thunderstorm twins and well over twice the crank rated 34 BHP of the stock thumper! How much does a P3 weigh again? Dry weight you say is 360 pounds? Are you grinning yet? Salivating maybe?

Imagine the look on an unsuspecting X1 pilot's face as you leave him looking at your tailight blasting <IMG SRC="> away from a stop. The kit is sure to be economical too! Just think of the wear you'll save on your front tire.

The engine is still in the midst of rigorous testing/development, but come mid-July Nallin Racing plans to have kits available for public consumption. And yes, for those wondering, the big bore stroker kit will require a new crank; thus splitting the cases will be necessary. Nallin Racing will be more than happy to perform that service for you if it is more than you are comfortable tackling yourself.

I'm reeeeeeealllllll tempted to start saving my nickels and dimes, and tens and twenties <IMG SRC="> for a road racer track bike fitted with a 44 Magnum engine. TOO COOL!!!

Not ready for a 44 Magnum? Nallin racing currently has a 515 cc high performance kit for the Blast that bolts right on, simple as you please, and you're pushing 50 RWHP. They also offer a 590 cc kit, but that requires boring of the cases to accomodate the 3-13/16" bore.

Check out http://www.nallinracing.com for contact information and other offerings from Brian Nallin and the folks at Revolution Performance.

Stay tuned for updates and photographs...

PS: No price yet. How much is it worth?

That is impressive... Bare Bones Machine...though bikes like these put out over 70 horses and weigh in just under 250lbs wet...and are aircooled singles as well.

minor correction ... the 590 kit is not a bolt-on, it's a 3-13/16 bore with the stock stroke and therefore needs it's cases bored. The bolt-on kit is the 515, which is a 3-9/16 bore.

Geez, and just when I thought the divorce was a bitch, it turns out it's a good thing (tm). Didn't have the dough to buy the 515cc kit this winter, what with buying a new house and paying the attorney to eff me in the rear, and it looks like it's worth the wait. Got a 2 car garage at the new house, and damn sure not gonna put the 700 dollar hyundai in it, so I guess I'll ride the Blast as is for the summer and tear it apart in the fall. Anyone ever figure out how to put a full fairing on this thing?

Rick: Cool bike! What is that? An MZ? I've always like those. I imagine the dirt track racer that Nallin Racing is assembling will weigh-in comparably. What's the price of a bike like the one you pictured? Is it streetable? Seventy HP at what rpm? Hydraulic lifters? Two valves? :)

BLAKE!!!!!! you had to do that didn't you!!!! Oh well that is more than I can do on my own and certainly not in Japan. Besides 70hp on the stock tire would have it roasting on a regular basis. which means swingarm work to run a bigger tire. Nice thing about it though with the tooling required for that the 515cc could end up cheaper.

Is it just me, or does anyone else question the wisdom of 70+ hp and the stock Blast frame, weenie wheels, and non-adjustable suspension? I hope someone is working on those issues, because that would be enough to get me off the Ascot and onto the Blast.

up for a little while, to avoid emarrasement at work!!!! :):) Besides I might slip on the pool of drool that has accumulated at my feet.

That absolutely ROCKS. It has been my dream as a fellow BLASTARD to be able to just EMBARRASS people on their chrome barges. Even though it may not be in the finances in the near future, I what to thank the Nallins for seeing the Blast for what it is. A really great bike with a ton of potential, and for giving it the money, time and research to make it so. Yaaaahooooo!!!

Blake, I think I'm man enough to try and tame that pavement pounding, firebreathing, sledgehammer.:)

At what point does one start to wonder why we're spending all this money on a Blast?

Let's say we're interested in a SuperBlast. We get Nallin's 70 horsie kit. How much?

Whew. That was steep. Now it just needs a new exhaust and carb to deal with the new psychosis. Swingable, surely.

Hmmm... Need some real meat with some real wheels... How much?

Oh man, that silly rear swingarm won't acommodate the new rubber. Hey, no big deal - it's only money.

Wait, the suspension isn't up to snuff. What was the $coop again on the rear shock? What about the weenie front forks?

Ya know, we've darned near doubled the torque on this motor - and we're still transmitting those massive power pulses through the belt that looks like it came out of a Walkman tape deck. We'll have to address that.

The brakes are fine, right?

It's a good thing we've already got the handlebars and rearsets.

Wow... a few weeks of downtime, a few paychecks worth of parts and machining labor and now we get to enjoy the fruits of our labor. Too bad we can only go 60 miles on a tank.

I don't mean to sound like a sphincter but how much do you want to spend on a Blast? You'll be THROWING OUT half the bike you paid for. I'd love a ground pounding Blast as much as anyone. It just doesn't seem to make much $en$e.

Of course, that doesn't usually stop me, either!

$en$e, the super singles crowd never seems to make sense to the unintiated. But then there are lots of things that don't.

I am going to cross post this over to the THUMPER list,it is right up thier alley. these guys buy TZ250 rollers and squeeze a big single into it.

Cost is not the issue, beating multi's on track or street is.

BIG SINGLES RULE!!!!!!

I have a GB500 and it is a cool bike, just needs more power. All it would take is a couple of thousand to install the big bore kit and hot cams, pistons etc. Of course I could buy a used 600 for not much more than that but hey what fun would that be?

Saro () :) said...

"At what point does one start to wonder why we're spending all this money on a Blast?"

"Let's say we're interested in a SuperBlast. We get Nallin's 70 horsie kit. How much?"

We don't know yet how much $$ we are talking about, but remember it is a single, so you'll only have one top end including valvetrain, a crank, some machining, and a new ignition module. The yield? We are talking about more than doubling stock HP! How much would a V-Twin Bueller pay for that opportunity? :) I'd look at it this way, 70 RWHP for significantly less than the price of a new M2. That's an assumption, but I'd bet on it's integrity.

"Whew. That was steep. Now it just needs a new exhaust and carb to deal with the new psychosis. Swingable, surely."

New exhaust? Blasters opting for a kit like this most likely already have a performance exhaust.

New carburetor? No new carb is required. The stock CV40 is good for up to 100RWHP and is stock equipment on the 1200cc twins. Of course, some rejetting/tuning may be in order.

Hmmm... Need some real meat with some real wheels... How much?"

New tire/rear wheel? Absolutely NOT required. Do you want a Blast with 70 RWHP or a racebike with a Blast 70 RWHP engine? That's purely a rider's preference. A wider tire is not required. The stock tire size will work just fine.

"Oh man, that silly rear swingarm won't acommodate the new rubber. Hey, no big deal - it's only money."

Again, rider's preference.

"Wait, the suspension isn't up to snuff. What was the $coop again on the rear shock? What about the weenie front forks?"

The suspension is configured for the weight, load capacity, and style of bike. That will not change with an extra 40 RWHP. Adding HP will not alter the corner carving or rough riding handling characteristics of a Blast. A suspension upgrade may be desirable, but it's necessity is independent of a desire for more power.

Ya know, we've darned near doubled the torque on this motor - and we're still transmitting those massive power pulses through the belt that looks like it came out of a Walkman tape deck. We'll have to address that."

The stock belt will work fine. The design load for the belt is not usually governed by engine torque. As to "massive pulses"... Rather, think about first gear and dropping the clutch at 4,000 rpm dragster style, or downshifting and missing a gear, breaking the rear tire loose at speed. Inertia, not HP is the proof tester of your belt. Have you noticed the size of the XB9R's belt?

"The brakes are fine, right?"

Yes.

"It's a good thing we've already got the handlebars and rearsets. "

Why does added HP require different handlebars and footpegs? That's simply a rider's choice that has nothing to do with engine output capability. If you ride aggressively enough to scrape pegs, it's not due to your engine's HP. It's due to your desire to take curves aggressively. The stock P3 will do 95 MPH. That's plenty fast enough to get you into trouble on most any twisty road.

Wow... a few weeks of downtime, a few paychecks worth of parts and machining labor and now we get to enjoy the fruits of our labor. Too bad we can only go 60 miles on a tank.

Does it take more fuel to cruise at 70 MPH when you have a big bore engine? Pick a proper cam, tune your carb, and your fuel efficiency will not deteriorate significantly. It's rider's preference. Pick a hot cam and jet her for the track, your cruising fuel mileage will suffer greatly.

"I don't mean to sound like a sphincter but how much do you want to spend on a Blast?"

Motorcycling is a sport that for the most part is NOT for the logical; it's a passion that gets into your blood; relationships between a rider and his/her mount of choice can create very strong bonds. The whole "why Buell versus a cheaper faster brand X" issue is similarly illogical. When it comes to motorcycling it's pretty much to hell with logic.

"You'll be THROWING OUT half the bike you paid for. I'd love a ground pounding Blast as much as anyone. It just doesn't seem to make much $en$e."

As I've shown above your belief in the necessity of "throwing out half the bike" is simply not true. As to making sense... neither does riding a motorcycle in the first place. :) And I'm sure the majority of Blasters will be satisfied with the stock configuration. For those that want a huge kick in the pants, and would rather upgrade their thumper than trade for a twin, the Nallin Racing kit will be a very cost effective alternative. I hope to have a ball park estimate on pricing soon.

"Of course, that doesn't usually stop me, either! "

Now you're talking! :)

Blake (thinking a stock looking "sleeper" Blast with the 44 Magnum kit would be a real hoot)

Blake, The bike pictured is built by Bare Bones Machine. They're using 90's Yamaha TZ-250 chassis' and mating 'em primarily to highly modified single cylinder Honda and Rotax engines. My particular interest is the air cooled Rotax powered bikes. SOHC, dry sump, dual downdraft carbureted heads, 4 valves per cylinder. The 675cc version makes that power at 9000rpm. Define streetable. I was told the most frugal could get one for $10,000...and a Supermono winning machine would be closer to $15,000...with most of that money going into the engine. Not too bad considering they've been beating bikes costing over 30 G's.

Blake-

First of all, I like the ass animation! Believe me, the resemblance is astounding! Just ask Da Woman...

Regarding the exhaust and carb statements, I imagine that a significantly larger motor will have different requirements there. Perhaps an adequate (even perfect) exhaust will not work as well on the significantly bigger single.

As far as the carb goes, the 1200 motors take two 600 cc sized gulps. The 720 single would be taking one large gulp. I don't know if that's really a good way to look at it - but it seems intuitive to me.

Does it take significantly more fuel to go 70 with a 492 or a 720? I don't know, but if you're asking the motor for what it's capable of (why not - you went through great expense to make it do that) then you might as well use at least SOME of that extra power between braking points.

Again, will it run? Sure. Will the same intake / exhaust / cam design parameters produce a similarly optimal result on a 492 and a 720? I simply believe that attempting to double the HP by simply upping displacement without comprehensive re-tuning will yield a boat load of disgruntled upgraders.

I'm certainly no engineer. I don't even play one on TV. However, I'm constantly having difficulty with how Blast oriented parts are priced - my real beef here. 5 bills for a Nallin 515 cc piston / cylinder. Add the head and cams - for which I can't find prices anymore - and it just doesn't make sense to me. Throw in the price of a crank and the related machining and it's really out of hand.

That's all I'm saying.

Oh, that and that I still want it...

Saro: I thought you'd appreciate the mooner after your "sphincter" comment. :) Glad you took it in jest as it was intended.

Of course the engine/cams will need to be a balanced package. I thought I alluded to that.

You raise a good point about the carb, I'll see what Brian suggests. Still the whole deal is a killer bargain compared to what you'd pay to double the HP of a V-Twin Buell.

Also realize that any parts that need to be swapped can be sold.

I don't see how $500 is hard to swallow for a state of the art piston and cylinder combo. I mean we are talking about a precision machined all aluminum Nikasil lined cylinder and a racing quality forged aluminum piston with rings. It's like anything retail, if it's not worth the price to you, don't buy it. That's the free market.

Like I said, it won't be for every Blaster out there, not even for most Blasters, probably just for a very small percentage of Blasters. But for those who DO want it, getting a high performance package for their thumper will be a very good deal. I don't know where you could find a better deal. Maybe Axtell or Zippers will have a more economical solution, but I doubt it.

I don't know about Axtell but I've been corrosponding with Zippers and they have't been able to give me numbers. And the gods know I've tried to get numbers from them. I also talked to Mr. Nallin and heres what he said. $500 for the cylender and pistons. $500 for stage 3 headwork (350 for stage two I think...thats what Aaron is using on his Salt Blast). And a cam will run you about $190. This is something I am seriously considering. A lot depends on my finances at the end of April but with luck I'll be running the 515cc for my last summer in Hawaii. Suspension is something I've been investigating as well but everyone I have contacted was either in Daytona or on their way there. Now that it's over I should be getting answers. Springs are cheap less than $100 in every case that I found. the rear shock is a bit differant but ASB has two options and there are likely others who make something that will work.
Blake, I think what Saro meant about the tires is that with 70RWHP the rubber in't likely to last that long unless you exercise extream caution. I squeal in 1st & 2nd right now what do do you think is gonna happen with more than double that. Granted the front tire will last longer as it isn't likely to be on the ground much. Honestly I can't see a reason for that much HP in the Blast.
Here's something to think about. Will double the HP mean that the engine will have to work half as hard to attain the same speed???

Well, if it were me, I'm just not a peak HP kinda guy, I'm after a lot of down low and midrange power. If I had a P3 to play with, I'd go for the 44" kit and put a short duration short overlap set of cams into her. I might only make 65 RWHP, but I'll have 50 or so FT-LBs of torque accross the board. I'm wanting what Brian refers to as a "short track" engine as opposed to a "long track" engine tuned for top speed. FAT power! THAT's what I'm talking about.

XG, you are about to open a long sealed and burried topic, the dreaded contact patch. Suffice it to say, no matter what size tire you run, if you exercise the throttle aggressively, your rear tire is going to wear quickly. A larger tire will not change that. A harder tread compound will.

I'd say that if your rear tire is squealing it's because of it's hardness and temperature in conjunction with the pressure you are running. My D205s have never squealed, they are just too sticky. My rear D205 lasts a meager 5K miles when ridden conservatively.

Contact patch area is simply the result of axle loading divided by the tire pressure. The shape of the patch changes according to tire design and size, but the contact patch area is simply independent of the tire size. This concept is virtually impossible for some stubborn old cogers (cough FB cough) :) to grasp, but it is a simple fact.

You will do much more for your rear tire's longevity by practicing smooth clutch operation and minimal rear brake use. Your rear tire squealing is a sign that your clutch operation is VERY agressive and that your tire is not so grippy. A grippy tire would have you lofting the front wheel rather than capitulating to the torque with a squeal. :)

My old yammer XZ550RJ was putting out 60HP. It used tires similar in width to the Blast's. The rear was a 120 and the front was a 90mm. Tire longevity was not a problem.

Double the HP, half the work? Not quite, you'll just get there twice as fast.
