i just bought a 88mm bore piston for my 05' EX. i had a brain fart... i forgot to get the top end gasket kit with the piston. who makes a gasket that fits this piston? or can i use a stock gasket set? i cant find a gasket kit on ebay for this particular piston, however some of the pistons are sold as kits with the gasket. just wondering if they are selling the stock piston size gasket, or the 426 bore gasket. let me know who sells it, or where to get one.
