The chasis is perfect but the motor has to be rebuilt and since its already fully disassembled I figured now would be the time to do some motor mods... So my question is... What would you do to achieve the best engine performance without losing everyday reliability at a 5k max cost? So far I've got a baker 6 speed and 1250 kit in mind but I have no experience in knowing what works best with what. Any help is appreciated! | ||

Skip the 6 speed, stage 1 motor work and 88" displacement no substitute for inches. there are several sponsors here that can do the work JTS can tune Cyclerama JET Revolution are all sponsors. I have worked with Cyclerama they are great, PreyBird had JTS tune his bike and was happy with the outcome, Jimmidan has an 88" motor built by Cyclerama and swears by it, I have seen the bike, its tough! all the names I listed are sponsors. | ||

any idea on $ for the 88 inch? | ||

that type of rebuild is the perfect time to eliminate all of the well known tuber "weak links" as well. new isolators front & rear, billet front motor mount, bronze oil pump drive gear, remove spring plate from clutch pack (replace it with 2 steel and 1 friction plate) I highly recommend cometic gaskets during reassembly. I've been flogging my 1250 rebuilt X1 for 6000 miles now and there's no sign of a leak anywhere. on a stock X1 motor and gaskets I had quite a few problems with the rocker box and intake gaskets. Tried OEM, S&S, and James intake gaskets - all leaked after less than 2000 miles each. | ||

definitely taking note of that, thanks for the input! | ||

+1 to what oldog and PK said My 1250 kit is sweet and with the SE .536 cams it makes tons of top end power   with tuning this project was 4k I got all crazy and bought everything!!!! Motor work top end work heads valves exhaust tuning suspension uly oil, pump bronze gear tranny upgrading race clutch, shift drum kit wheels tires brakes lighting Lots of carbon fiber lots labor current total with bike purchase price $5000.00 is....16,500.00 and still climbing! This bike has turned into an addiction and it must be fed!  | ||
| Buellerandy |
so in engine costs alone how much would you estimate? | ||

Preybird is yours still running the FI?. | ||
| Preybird1 |
Yes it is running the FI still. But it was custom mapped by JTS performance. the engine alone is $3,000.00 only because i had to have new heads and the shop installed them for me. | ||

Buellerandy, depending on how much you can and want to do yourself you can keep the engine build to around $1500. I took mine all the way down to the crank pin over the winter, installed a 1250 kit, new gaskets and a few other goodies and it came in somewhere south of $1500. I'm not a mechanic but I play one in my garage. If you need/want any help or ideas drop me a line. Michael | ||

will do, I'm still trying to decide if i can afford such a project lol. | ||

Ever ride a stock X1 with a good intake,exhaust, and race ECU? With the factory internals, it's plenty healthy. also, what went wrong with the engine that would make the previous owner take it all apart? | ||

Your talking about spending a shit load of money on a bike you are not familiar with? HMMM Either your crazy , rich, or just have alot of time on your hands. You really need some help, Find someone in your area to help you with the reconstruction. Either hang out at bike shops around quitting time and talk to some mechanics about helping you after hours or something like that. | ||

Russ, did you go with a modified throttle body, or bore your TB? Just wondering  | ||

"... a stock X1 with a good intake,exhaust, and race ECU? With the factory internals, it's plenty healthy." I agree 100%. While I appreciate the notion of there is no such a thing as too much power, I'm willing to bet a lot of folks have a "sick" X1 and then pour a lot of money in it thinking it needs more power. It does take time and patience to get the fuel maps dialed in for the intake/exhaust, etc, but when done right the thing is scary fast and pulls right from idle to redline like there is no end in sight... | ||

I agree with Nate. A good stock X1 makes great power.I once built an 89 inch engine then experienced POOR reliability. I can hear a nice howl around 4500-5500 | ||

No boring of the throttle body just a damn good tuning and map work! |
