310 Big Bore Stroker

[cehmke]

I was told a good dune racer would be a big bore 310cc stroker. Would this not be a problem for headgaskets. ? I wanna do it, but not if im gonna haveta be rebuilding it every other time i ride. Any suggestions ?

well most big bore kits come with the head,and a o ring type gasket.i dunno about reliabilty,but esr told me they have built them so long they have worked out the bugs.

Esr kits are more reliable then stock cylinders.. pro-x has spent 15 years workint he bugs out of them and now they r just badd grass cylinders... theyf rikin smoke... 52 rearwheel horses on a basically mild all around por tjob? yah take one to the porter and let them know what riding you want... easy 60rwhp on 110 about 55-56 on pump
