stroker crank

[dempsey400]

how many of you have built a stroker for the 400? Is it worth it?where did you get it and how much was it? What other mods did you get? Thanks.

from what i read:

great for trails and low end power. not good for high end power and drag racing (unless you go huge, like +500cc's).

I am building it now hope it kicks a@#. I got it from Powroll got the heavy rod too.

I heard Dennis Kirk is selling stroker kits not sure how good they are.

One of the best things I ever did to My Baby!!!! Look at my signature for all the other Mods. Cost close to 500 from Powroll--Check out their site!!But well worth it!!! Had to beat the HEL out of the Yamaha ha ha's. Excellent top end, Ferocious Revvvvs....

is there anywhere that i could buy JUST the stroker crank and a 13.5:1 je piston kit for a reasonable price like a 4mm stroker or something that will give me a little bit more all around power?

lookin to be faster:macho

what needed to be machined for the stroker crank to fit?

everything fit fine no machineing need to be done just crank work.

depends on how much of a stroke you go, I have a 7mm stroke and my counterbalancer had to be machined down and the front skirt of the piston had to be shaved some

[ZQ8Dude]

whats the highest stroke you can go without machining?

I believe 4mm is the largest safely
