Product Overview
These cylinders are more modern versions of the 2-port Sprint 150cc cylinders and make great performance upgrades for ALL 2-port rotary valve models including those terrible deflector piston engines from the early 60's.
When used with a Sito Plus exhaust and a 20/20 carb, it's common to reach speeds of 50-55 using a 3-speed VNB engine! (We do not recommend fitting a Sito+ exhaust on any 8" model unless you like hearing your exhaust bottom out on bumps).
Fits 2 Port Largeframe engines:
VNB
VBB
Allstate
GT
VLA, (GL)
VBC (2 port Super) and similar engines.
Cylinder head (part # 90970) not included and is required if not being placed on a Sprint!
Cylinder assembly Includes cylinder, piston, rings, wrist pin and circlips.
