How about 600cc? Here's my plan. I want to get the 600cc big bore kit, the 4-valve head, and get the appropriate valve lifters and such. My budget is limited, so I'm thinking going big bore first, then the rest later. What's my best course of action? | ||
| Ezblast |
LOL - you need to go to the quick board 600cc topic - don't bother too hard - I'm going to move it to the KV now to make it easier for you to find - ask Nick about that head. I'd stick with NHRS or CycleRama and just go for the XB heads modified, but thats your choice and a hell of a lot more work - more power to ya and good luck. Big bore, head, ignition, cam, better exhaust, intake - if you where doing it by piece - that would be the order I'd follow - Have Fun! Got Thump?! Just Blasting on the Dark side! EZ  | ||

 LOL, on a Budget now-are ya Joey !? The 600cc big bore will cost you Big bucks to buy, and install as the whole motor needs dis-assembled to have the cases machined... that work ain't cheap if you can't do it yourself ?! And unless you are totally familiar with these engines, I wouldn't want to learn on it ! As for the 4 valve head-OMG Man, do you know how costly that is !??? And that head would need special/custom adapters to mount it to the frame. And would it be worth it ? Ahhhh, I've heard of No racing Blast in the Nation using a Four Valve head ! BTW- if by some chance you did have the $$$ and did accomplish all this work, would it be worth it to have spent about $4000 dollars extra to build your Blast up to the speed of a stock $4795 Kawasaki EX500 Ninja ! That my friend would make YOU even more obcessed than either EZ or myself ! IMHO, if you wanted to go that fast, and were on a budget- you NEVER should have a bought the a Blast in the First Place ! And if you wanted even faster than a 600cc Blast/Ex500Ninja, you could have bought a Suzuki SV650 ! | ||

I saw on the Nallin site that the 515cc kit only adds 7.5 more ft lbs of torque? The stock number is 30. Is this worth $625 plus labor, even though the HP went up to 50.8? | ||
| Rockbiter1 |
every ft lbs helps  Besides, what else are you going to spend your money on, since the bike itself is so relatively inexpensive? Go on, treat yourself! The REAL one to get is the .44 Magnum kit..special order only, 44 cubic inches of thumper goodness! | ||
| Blaster_s |
Thanks Rt3. That's what I suspected. I looked into the kit further and I at least need new cams, new ignition, etc. It may be a little expensive but that's what Buell makes the XBs for, right?  | ||

Spending that much money on a Blast ($2000 for a stage 3 kit) makes you a true Blastoholic. When you start thinking of putting that kind of money into a Blast you have to ask yourself what are you trying accomplish? If you really just want an XB, save your money, cuz the Blast will never be that. All the Blast modifications mirror XB mods,its just the total HP output is cut in half. When mine gets back together, my friends will again ask, why? I'm a Blastoholic! (Message edited by gearheaderiko on November 08, 2004) | ||

I paid $2000 for my Blast and put $1000 into it w/ parts and labor: Pro Series Air kit, Pro Series Exhaust, XB9 handlebar, Dual headlight setup, new tires. I love this bike but don't want to put another $1500 into it for 7ft lb of torque. | ||

Here's that same bike in more of a street tune:   Also keep in mind that torque is not a performance metric, at least not by itself. It's essentially meaningless without also considering the rpm the torque is made at, and when you do that, you're talking about horsepower. The torque at the rear wheel (i.e. where it matters, as opposed to a dyno sheet which shows engine torque) at any given ground speed is defined by the horsepower available. As this bike has 76% more horsepower in modified form than it had in stock form, it's capable of putting 76% more torque to the rear wheel at any given speed (assuming it's geared to be at it's power peak at that speed). | ||

Looks like that would be over 11 ftlbs of torque - actually in the money for HP game thats a damn cheapo price! - exhausts and cams (not counting labor) have always been the bargans in ones hunt for HP, however, the old rule of thumb was 200 to 500 dollars per HP gain on a motor - thats why the kits are popular - a true working bargan that adds a lot more fun to an already Blastastic platform! - lol GT - JBOTDS!

I'm looking at the Performance kit from these guys: http://www.revperf.com/xl.aspx?action=exhaust Looks like Brian Nallin is working w/ these guys now. | ||
| Ezblast  |
Fair warning - the Millinium cylinders have had problems, knock on wood, which is why NHRS went to Axtell - not a reflection of Nallin who is and was still a great guy, and that was their past, have heard little recently about the Millinium cylinders - thats good? - GT - JBOTDS! EZ | ||
| Blaster_s |
Ok...I'd like to get the 515cc Bolt-on Big-Bore kit from Nallin Racing but should I get new cams and ignition too? Or Should I forego that and just the Buell Pro Series cams and ignition and call it a day? I'm just looking for more bottom end torque. | ||
| Newblaster  |
To do very much at all with the ignition, you need to do some headwork. The stock springs won't take much more than (IIRC) 6800rpm. Plus, headwork is always a good thing. lol... Soon, EZ will chime in here. He's tuned his 515 quite nicely... | ||
| Ezblast |
The big bore kit by itself is a sweet start and with the Pro-series/Andrew B-50 cam the bike definately becomes a different animal - this would be a great start especially for further mods down the line. Later - upgrade the head springs, guides and valves, port/polish, 3 angle/blending valve job for better breathing, and then step up to the ignition upgrade - and SE550 cam, then when all is said and done with that and the bike starts to feel ordinary again, then step to one of the different hi-performance cams available. This keeps the prices for each upgrade more reasonable to deal with as a project - lol GT - KBOTDS! EZ | ||

The piston is what makes the 515 work, more than the increase in displacement. You could buy the matched high compression piston, get the cylinder rebored (stock size overbore) and spend the money you save on B50 cams! The ignition is a pointless expense unless you do the headwork (valve springs,etc). You're on the right track though, think the series of mods through first and decide ultimately how much you are willing to spend. OR: if you're going to do the 515,then you should get cams. If you're getting cams, might as well do the headwork.Well if your doing headwork, might as well get an XB head.You'll need the ignition now. Well the 600 kit is the same $$ as the 515, so you should do that instead and since you'll have the cases apart, you should probably fix that 1st to 2nd gear transition.Baker 6 speed & flywheel lightening will soon follow as you spiral into madness and the Dark Side has you!! | ||

Practical question and after certain facts - but I did notice this - http://www.nallinracing.com/partscamshafts.shtml just what is the power increase of the SE E series cam over the Andrew B 70 ? Their specs do'nt look that far appart - hmmm? GT - JBOTDS! EZ | ||
| Blaster_s |
So the cams should give more a little more grunt down low, right? (Message edited by blaster_s on January 18, 2005) | ||
| Ezblast |
the B-50/Pro-Series - yes definately what they are all about. GT - JBOTDS! EZ | ||
| Gearheaderiko |
Midrange more likely. Your never gonna turn the Blast into a stump puller! | ||
| Ezblast |
Stump puller - no, however, I did notice the takeoffs become much quicker, and any low end hessitation disappeared - many say the B50/Pro-Series should have come stock in the Blast motor - I tend to agree. GT - JBOTDS! EZ | ||
| Gearheaderiko |
Agreed! | ||

I noted that EZ's earlier post vis-a-vis NHRS cylinders indicated that "Millinium cylinders have had problems, knock on wood, which is why NHRS went to Axtell" . . . can anyone determine from this ad which cylinder is currently being advertised on Ebay? Here is the link: http://cgi.ebay.com/ebaymotors/515cc-Bolt-On-Big-Bore-Kit-for-the-Buell-Blast_W0 QQcmdZViewItemQQcategoryZ35572QQitemZ4565266269QQrdZ1 Thinking about a preparing for a winter project . . . | ||

Thats the nickel-silicone-carbide plated all aluminum cylinder - which is the Millinium eddition, however, I found the secret to the cylinder not wearing excessively was to use a regular top ring and the rest of the rings total seal - found this when I was wondering about noted problem and the ways around it and the mfgr's solution - heavier coating for better coehession to tolerate the abusive top ring - lol - so for the old style cylinder use an ordinary top ring to play it safe and on the the new stuff from Millinium - don't sweat it. Step the guides in your head, heavier springs, go to bigger valves - titanium, and have a shop Port/polish and multi-angle valve job, nice thing about a single is that you don't have to match flows in the head - let em have at it for max flow. An SE ignition, and tune the carb with a dyno, perhaps add a thunderjet, dial-a-jet, or sporster secondary pump - see the carb section for carb tricks - don't be suprised by the lower jetting - the Axtell piston is designed for the Blast head unlike the generic sporster 1200 piston - lol - you can also get it in stock sizes - another way to go - street cams are the B50 Andrew/Pro-series, B70, or SE series - lots of ways to go in-between or larger - Erik B mentioned offsetting the cylinder, bigger bore and stroking her up to 750cc and had ridden a factory 650cc Blast - he said it had around 50 hp - said it was fun!

Ok finally got the money together for some engine upgrades. Looking a head work of course, question I have would be which 515 bolt on kit ? NRHS or Revolution Performance ? Any experience with either vender ? Once again thanks in advance Have a great day | ||
| Ezblast |
I would go with the company that sells the Axtel cylinder - why - because you could bore it out come the next rebuild time, or you could take your stock cyl, bore it to clean out the sleave then add a high comp piston and total seal rings - either 10.5 or 11.0, with all the money you saved on not buying the kit you can apply to your head - upgrading even further - I'd step the guides - extra work but makes everything much more reliable - you could go with bigger valves, better springs, and guides and seals and then have a local company do the head work - since no balancing to match another head is required - though if I was just having the head done - I would send it to Wes to breath on - he is the Head artist - lol - cams used would either be the SE550 or the B70 - or if just racing - the N9 produces max hp.

You cannot bore out a plated cylinder. Sponsor plug: Revolution Performance is reputable (they plate the cylinders for the XBRRs), supports this place, and they provide a lifetime warranty and a competitive price. Please support our sponsors. | ||
| Blake |
I see you are in Sarasota, Florida. It might well be a crime to not drop your Blast off at Cycle Rama in Pinelas park and let the local experts take care of you. | ||
| Gearheaderiko |
Amen to that Blake! Without them we wouldnt have this great resource. I agree with EZ. Spend your money on head work and cams first,then match a high comp piston. I think you'll get more bang for your buck than just going up to 515. Of course if you've got money for everything-do it all! | ||
| Gearheaderiko |
Is NRHS no longer a sponsor of Badweb? |
