I believe just prolights, durabuility is not an issue with theese pistons, 95% of piston failures are due to incorrect clearance, or jetting issues.
I would pick a site sponsor to do the bore and chamfer of the cyls. fast,hjr, redline, m&m,wildcard.
if you don't have any porting done the vito's piston will give you a little bit more, the vito's piston is forged by wiseco and vito does the machineing. I used to run them and liked them.
how are the atv trails in kalkaska?
the saint helen trails and ogemaw trails are fun!
we ride the dunes 4 or 5 times a year, kind of a pain in the a to get a big group together, the way things work there.
I;ve never rode the U.P. how are the trails around gwinn, are there many?
It would be fun to get a big group together to trail ride some where north, there are several guys around our area that would proly be in for a group camp and ride.
