Default 61mm GY6 B cylinder

Hey guys finally have a performance product for those GY6 B engines with the 2 bolt valve cover. As many know the 2 bolt valve cover engines found in the Sunl and Roketa 150cc buggies as well as other off brand buggies will not accept the normal mods used on the GY6 engine. So there is no longer a need to purchase a new engine to mod your engine.This 61mm cylinder is a top of the line cylinder from Taiwon. The cylinder bolt spread measured diagnoly measures 3 1/8" where as the usual GY6 has a 3" spread.Since the B engine incorporated a sport high lift cam stock the big bore will make the additional power you have been looking for. This is not one of those drop in kits and will require the case to be bored, a service SYC Powersports offers. Add to the big bore a ported and polished head, another service we offer to really wake up the GY6. The Kit sells for $149.00 is in stock and if you mention Buggymaster when ordering I will ship it free limited to continental US 48 states. TOM
