Just curious if anyone here is familiar with the set up I have gone with .In reference to the 440 I.M.S big bore 88.5mm piston, Edelbrock 440 carb, stage 1 cam, Barnett clutch, and White Bros rev kit. I'm not sure how different it's gonna be so if anyone has this as well as knows somebody who does let me know what I'am in for as far as increased performance and problems I might run into. Like I said before all the motor work and cam and carb and rev kit are being installed this week.........Thanks for your time. "Da Reaper":devil:

You will probly be pushing about 35-37 hp. But if you got some headwork done it would wake it up even more.

like what for instances for my particular soon to be set up? I also was told to redo the bottom end with a new crank and 12mm headbolts as well. The head-bolts some guy said so I dont blow head gaskets all the time. Is that true?

I never had any problems with my head bolts. Some people do though. If you are eventually getting a stronger rod you may as well get your crank stroked while your at it.

The rev kit will give you more problems than its worth. If its cold they dont want to start. And the motors power curve falls off after the stock rev limiter anyway. Not to mention it starts to add more stress to the rod. If you want the extra rpm's just go to a honda dealership and order a cdi box for a xr250 same thing as the white bros cdi box but cheaper.
