Piston, cam, bigbore for 400?
Posted October 22, 2008 - 05:21 PM
With my old 4 strokes, i would always add a highcompression piston and a cam, and maby bore it.
My question is with the 400, what is stock compression, and can i run a higher compression piston with pump gas?
would an aftermarkert cam set like a hotcam, etc really make a difference in power?
Do they make a big bore for an older 400 like mine?Is it possible to swap in a newer 450 cyl? thanks alot guys....been riding the bike stock and love it, but always looking for more power....ive been riding with streetbikes lol.

I was looking into this and didn't finish the research. I was thinking that if you only wanted to go to 426 you could buy a 426 jug and and a proper oversize piston for the 400, you might be able to do this without the crank/rod change. Maybe some else knows if the piston is availabe. This could save some cash.

I see they make a 13.5:1 400 piston and 426 piston.
Could I buy a 426 or 450 jug(same 95mm bore), buy the correct piston and bolt it up?
Do all years use the same wrist pin size? I heard there is a cutoff year, but wanted to verify.
can you run 13.5:1 on premium?
