Steve: At your suggestion I have placed a new topic "Engine - Camshafts, pushrods, lifters" here | ||

Jose Don't know what's with the thick fins, that's just how they came. I've had them about 12 months. Steve The only timing figure that will affect your effective compression ratio is intake closing. It can have a fairly major effect depending on duration and intake lobe centreline. I have some software from Performance Trends called Compression Ratio Calculator which can work it out - recommended - it's cheap and good. Have a look at the RedShift cams at Zippers | ||

Re- Compression Ratio calculator. Thanks for that. Steve http://ukbeg.com steve@ukbeg.com | ||

Nallin big bore kit? any one try it yet? If I understand correctly I can install the kit and get up to 115RWHP, (finely tuned). I am interested in what I can get out of a X-1 Buell race pipe, w/R-ECM, Force winder intake. stock heads. Looks like a good artical for B2WIN. | ||

Skulley... You talking about the 1250 kit or a BIG BORE? Kevin at Widman's HD in St.Louis has done some of both. Give him a call. The 115 hp dyno sheet that is posted on the 1250 kit came from there. The number is 800-404-6880. I was there the other day when they were doing some dyno tuning on a 3 13/16 motor they had just put together. Got to love that extra torque! | ||

Kelby: X-1/ S-3 with race ECM, Buell race exhaust, and intake are usually in the 88-92 hp range, with 68-75 ft-lb torque. Big change with this configuration is in the 2500-5000 rpm range that gets filled in vs. stock. With a little head work and maybe SE-II cams you are usually in the 110-115 hp range. Neil S. | ||

Neil: 110 RWHP with just heads and cams? Please tell me who did your heads!  | ||
| Ccryder |
Blake: Just go talk to Brian Nallin. Unfortunately it's not my bike but.... I saw the dyno slips, I have rode it, and most of all, I have tried to keep up with it on my X-1. It is real HP and TQ! Neil S. | ||

I was talking about the Nallin 1250 kit. So what is the best buck investment? Which will net more power? Heads and cams or the 1250 kit. Like everyone else, I eventualy want it all. but reason says one thing at a time. The credit cards are full. | ||

Blake: he's right, the bike he's referring to (an S1) goes like stink, I've seen it. Mostly disappearing from view in front of me. Skulley: no question, the heads and cams. With the 1250 kit, you're talking about less than a 4% increase in displacement. Not that it isn't worthwhile, just that you can get much more than that by working on the breathing first. AW | ||

But no pistons?  | ||

I bought a '98 S1 last Spring. I love my bike(best investment I've made besides school)but I want more power (and really anything to improve its good performance). Most of what I've read here seems great but much of it is a little beyond me to make the best use of it. What I think I'm asking for is some advice regarding finding a good mechanic and some general ideas that seem to work for others. I really appreciate this website. Thanks. | ||

Bighead, the best bang for the buck would be the Pro-seies race kit. This includes longer primary tubed header, muffler, ignition modual and ham-can air filter. If you find this expensive, install a slip on pipe, pro-series race ignition, toss the tube in the air-box and install the ventury ring from H-D. I think the part number is 29179-88, I'm not at work. The ring is a couple of bucks. The stock main jet should be a 200 which is fine. I recomend a 45 low speed, but others may tell you a 47. As for a mechanic, if you lived in Vancouver Canada I could help you. My advise would be to purchase a BUELL service manual and become familiar with your S1, they're so easy to work on for your basic needs. | ||

It is amazing to see a Buell generate 115 HP. W/o confirmation form reputable sources I would have never believed it. With just the right combination of parts Brian has achieved quite a significant amount of power from our beloved Sportster motor. It is a sad thing that I already did my motor up when these new 3 9/16 jugs and pistons were not yet available. Another 1,000 $'s plus the headwork would do it! Hmnnnnn... I already have all the other periferals, will my wife... no I don't think so...better wait for the next fast bike that hits the showrooms... | ||

Gootch, thanks for the help. I live in southeast Washington State. I'd love to take a ride up there when the northern passes open up and stop in. I was there for the Molson Indy, Vancouver is fantastic. Happy Holidays! | ||

Turbo and/or NOS Q... is there a solid unit(s)available for my '01 X1. Has anyone had luck with the set-ups on the market. Any info. will be taken serious as I am in the "winter blues" stage of biking and want to improve the performance with bolt-ons at this stage!!! Steve | ||
| Vr1203 |
Steve check this out turbos | ||
| Peter |
Try this one. PPiA | ||
| 911buell |
Thanx Vr1203 and Peter... I have some very good reading ahead of me. I will update with modifications as they progress. Cheers... Steve | ||

Kick ass!! Nice calander girls there too PPiA | ||

Guys, the 1250 kit is NOT from Nallin; they are selling the Millineum kit, that sells for $895, including pistons and gaskets. (920) 893-5595 | ||
| Buelliedan |
Dave, The 1250 kit is a joint effort between Nallin and Millenium Tech. Nallin makes the pistons, Millenium makes the cylinders. http://www.sporttwin.com/nallin/ | ||
| Aaron |
Millenium is a supplier to Brian, just like CP is for his pistons. Brian did the development work on the package. | ||
| Buelliedan |
We can always counton Aaron for the definitive answer!! | ||
| Aaron |
I didn't mean to imply your post was wrong, though, Dan'l ... although I haven't discussed it specifically with Brian, I wouldn't be surprised if there's a cross-marketing/joint-effort agreement where Millenium can also sell the package. As it was explained to me, the thing was born out of the Super Tracker rules allowing 1250cc for pushrod twins, a series that Brian contests. He worked with Millenium and CP to get the parts made and developed the package racing and then put it on the market. A few weeks back I put the full kit on the Blast. I had the cyl on there at Bonneville but was using the 1250 piston and as a result I didn't have a whole bunch of compression. Now I have the Blast specific piston and man, it's a really nice piece, he really did his homework. Very nice fit to the squish shelf, it took next to zero work to fit it up. Miles of piston to valve clearance, he added a bunch because we learned that the long rod of the Blast was causing enough extra tdc dwell time to start pushing things a bit. All rounded edges. Lots of compression too. AW | ||
| Blake |
Dyno? | ||
| Aaron |
Yeah, but I'd rather not say at this point, I'm not done. It makes a whole ton more power than a stock Blast and it definitely makes more now than it did with the 1250 kit piston, how's that? BTW, I confirmed that BuellieDan is 100% correct, there is very much a joint agreement in place. I got a 1250 kit as well as the Blast kit but haven't had time to do anything with it yet. I was going to put it in my M2 but now I'm thinking the S1 instead. But right now I'm working through old projects, just reassembled the Blast and RR and now I'm working on the XR. The M2 will be after that (I have a new plan for it) and then I'll put the 1250 kit in the S1. And I want to do more development on the Blast as well, it's making good power but I think I can do better. AW | ||
| Buelliedan |
Aaron, XR? I thought the RR had the XRs motor in it. Is this the end of the LSR bike as we knew it?? | ||
| Aaron |
yes. | ||

Lets all bow our heads in a moment of silence!! |
