425 on the way

The power bug bit me hard today! I ordered my JE 88mm Piston 425cc 11:1:1 compression. I also plan on having the Flywheel lightened too. I hope these mods will compliment the DMC exhaust and XR Cam I have right now. I haven’t ridden a 400 other than my own so I really don’t have any idea what kind of gains I will see or if I will even like it. Right now I really like the power it has it does great 3rd gear wheelies and good top end speed. I guess I just want to be able to do 5th gear wheelies now. Or this summer really fly across the dunes. I want the quad to be the best built XC race machine I can. I like to ride the trails a lot, so that power in every gear is important to me. I opted for the 425 than the 416 because I feel it will offer more torque and should rev pretty fast its self. I’m trying to find a happy median between the Hi revs motor and Hi Torque monster. Also It seems that I will be in search of a good gear ratio for this motor. So if any of you out there have a 425 and can give me some type of info on this, I would really appreciate it. :devil

Well Guy I've never ridden a 425 but if you've never rode a modified 400ex then you got one heck of a good thing comin buddy,,you'll look like this on your first ride.:D I can't wait to here your first response out here when you take your first ride,,you talk about full of chits and giggles..

good luck with the 425........hopefully everything works well ...have fun

o man u ain't comin out to pa now i don't want beat:D haha... so kendrick u been talkin about this 425 for awhile now and u finaly got it... u will love it i can't wait to ride it too:D TOMMY

thats pretty much how i decided on the same setup but i only want 10-1 i also was curious on gearing and jetting would a 40 pilot and a 170 main be the hot setup? also what size pilot without the choke? what kind of power gains will i gain from eliminating the choke? i dont want to fork out the 400 bucks on the fcr right now but mid season i will! just trying to get by for now! where did you get your parts from? how much? je or wiseco

I want to know what you think of it.
