     Limitedx1 |
what is the answer for an x1. i want the most horsepower i can still ride around the street. i will occasionally ride two up. i guess i want to try and eat tires twice as fast as 90 horse eats them now! looking for the magical 100 horsepower or beyond the easiest way possible. no engine mod is too hard, cylinders, heads, piston, cams etc... | ||

My "build constraints" were . . . "I want a fun bike that I can start in California and ride to New York with no concerns". It came out 111HP and in each case where we had a power vs. reliability decision we went with reliability. Including sticking with the existing muffler to keep from getting on the neighbors hit list on Sunday morning. | ||

well i already have a race ecm and force pipe, so im guessing i need some different cam grind and a head job, what options do i have injector wise? | ||

We've all read bits and pieces Court - tell us in one spot what head, cams, displacement etc. is in this reliable hot rod of yours! | ||

>>>>>>tell us in one spot what head, cams, displacement etc. is in this reliable hot rod of yours! Ahh. . . I could tell ya . . . but then I'd have ta THRILL ya!  | ||

If you are gonna ride it daily, go with 1250, cams, and HEAD WORK/HEADS You can either do up the T-Storm heads, or start fresh with XB heads, and build off those... When I was looking into this, and speaking with several builders... Discussing my riding habits, mileage, etc.. Basically, it was decided that the 1250 will do what I want, in a more long term set-up... One builder in particular flat out told me, based on my habits, stock cases probably wouldnt last long under a 88 or 90 incher... SO, knowing what I know, I went 1250... heads will be handled this winter... Anyway, the 100rwhp mark isnt that far off, IF you do it right, and TALK with who is gonna build, or supply you with parts... I assembled my own engine, BUT, bought the parts from builders...

Thrill me, thrill me!! I gotta know! I see its always the same for a few of us. We want hp but want stock reliability. This conversation will be had again as it was done several threads ago, SO, give it up!! What do we need? Asking, maybe a little bit of begging, but never whining. Pretty please? Cherry on the, oh the heck with it!! Tell us oh grand poohbah of knowledge and wisdom, Court. | ||

What Chase said. Go w/ 1250 Kit, doesn't require case boring. Avoid case boring, extra HP's not worth losing structual integrity. Depending on financial restraints, maybe stage 3 heads from NRHS. I imagine that combo w/ give you 130+ RWHP. If you need more than that, get a different bike. PS I assume you already have done basic mods, exhaust,chip and intake. | ||

130+hp really isn't going to happen with a 1250 kit .. even with stage 3 heads .. best hp number listed on NRHS's site for a 1250 kit (with stage 3 cnc xb heads) was just over 120hp - other than that all were not much more than 110hp .. which can be achieved without a 1250 kit or stage 3 heads btw) | ||
| Warlizard |
Just double checked the NRHS website. As I thought, they claim 124 RWHP on an M2 just by adding 1250 kit. I gotta believe w/ stage 3 heads you could get 6 more HP. | ||
| Chasespeed |
130+hp really isn't going to happen with a 1250 kit Uh, okay, but, his magic number was 100 }looking for the magical 100 horsepower or beyond the easiest way possible. IF he was looking for BIG power, I wouldnt have mentioned the 1250... Chase} | ||
| Warlizard |
After looking further, the claimed 124 HP includes some form of headwork. They are not clear as to what stage. If you go w/ NRHS Stage 3 1250 kit you should get at least the same output if not a little more as X1's come from the factory w/ more HP than the M2. BTW the kit is 2800.00$ | ||
| Wile_ecoyote |
Okay, we agree (basically) on XB heads. 1250 kit with what type of piston? High/Low dome Or is there a specific type that needs to be used? This is just a discussion as Iam nowhere ready to do this. I'm pleased to say I'm learning my way around the handling and hp #'s I have now. I dont mean to hijack the thread but it appears its a free for all anyhow. My idea? Nallin cylinders in 1250 with XB heads and stock X1 cams with pushrods. Could it really be that easy? Downfalls? HP #'s to be expected? Right now,02 X1 with race ecm, race pipe and forcewinder intake. Tatt, you mention extra power without all this. Whats the scoop on that? (Message edited by wile_ecoyote on August 07, 2007) | ||

Kit comes w/ Hurricane pistons. Go to NRHS website. Click "engine kits" then click Buell for tube frame years. It will answer all of your questions. As far as HP, I only repeated what they claim and according to them 125 is a distinct possibility. If you go w/ the stage 3 kit you get everything, cams, pistons,valves,springs etc. | ||

If I wanted a fast street motor I would start with a Kawi ZX12R. Full system,K&N, Powercomander chip, and a rear sprocket swap. It'll go as fast as you can stand. Oh you ment an air cooled push rod motor, LOL, I don't think that kind come in fast, only medium & slow. Never mind (Message edited by Danny_h__Jesternut on August 07, 2007) | ||

Thanks but no thanks, I like my potatoes lumpy and stay away from the rice.  | ||

Chase - I know *his* magic number is 100 .. I was responding to the 130hp claim from heads and a 1250 kit .. Lizard - that 124hp did include the stage 3 xb heads - and it doesn't matter which bike came with more hp - nothing stock was left in that M2 - they did cams as well as headwork with the 1250 kit - the result would be the same whether it was an M2 or X1 ... everything was swapped out for new/better .. Wile e ... you can get 105 to 110rwhp without a 1250 kit or stage 3 heads .. and you can do it for under 2 grand ... He could get easily get 98rwhp with the race kit and a Power Commander without any engine mods .... ... add standard XB heads and XB9 pistons and he'd easily have the 105-110rwhp ..

My feeling is that you'd be well served talking directly to one of the performance shops that sponsors and participates on BadWeB. Check out Cycle Rama, JET, Revolution Performance, and Hal's. If you were in Europe I'd be recommending Hillbilly-Motors. | ||
| Tattoodnscrewd |
FWIW - all of the info I have at one point came from one of those sponsor's ... Hal's .. it was either them or Buell employees I got my info from ... | ||

Questions you'll want to have answers for include, what kind of power delivery are you most interested in, big low-end, a compromise for best overall performance, big mid-range, or optimum top-end? You can get 100 RWHP with any of those types of 1250cc Buell performance jobs, but you might end up disappointed with 100RWHP but only 65 FT*LBs of torque at 3,000 rpm. For me the big low and mid-range power is much more satisfying than optimum peak HP and if you ride in that realm of engine speed, the engine will be more reliable over the long term. | ||

"For me the big low and mid-range power is much more satisfying than optimum peak HP..." Big midrange fits right in with my riding style. When I'm really railing the corners, being able to stay a gear higher (than I typically would) and using the clutch to get at the midrange (when I'm just past the apex) literally rockets me out of the corners. It's a riding style I had to adapt to, but it works better (for me) than screaming the engine past it's torque peak in a lower gear. The more you learn to use the mid-range surge, the more effective you'll be with this type of engine. | ||

This is why (correct me if I'm wrong Brian) Tattood is so happy with his set up and so strongly recommends it. AND his opinion and set up was gained from Hal's! I think the point about using your barrels and XB9 pistons is the HP/$$ ratio. There is no reason to expect much more than a couple of ponies from going with a 1250. Even if the HP gain is linear - meaning at a stock 88 RWHP you are making .073 HP/CC the gain would be .073 HP/CC X 47CC = 3.43HP. Great if you need new barrels anyway, but not much bang for the buck.....Now if Aluminum barrels are available and you need or gotta have the 1250 maybe the weight savings will add value..... | ||

The bike currently has 25k miles on it, daily ridden to work (82 miles round trip). Those numbers should be capable by an X1 as well. |
