have 4mil, want to go to 7mil or 10mil

[sandfreak03]

I got a 4mil right now 426cc. I want to get a 7mil or 10 mil. how much & whats the power difference? I need some suggestions, please.

[vulvafan537240]

the cases have to be trenched for both cranks and i believe the cranks are about the same price. so its about the same price for either setup. id go with the 10mill.

 

are you porting stock cyls or going with a cub, cheetah etc?

no sense in doing the 7mm.. go with a 10.

Not sure of the riding your doing but id be thinking about trying a different carb and pipe set-up over the larger crank first. Just have heard of allot of guys bumping up to the larger strokes and not finding the bang for buck ratio they were hoping for. Iam not speaking from experience on this but just what I have heard around campfires with people who do have the exp so I maybe mistaken. Just something to think about, again, allot of it would depend on what riding your doing or are after..
