New for 2020 GZR is our OEM 30 Plus motor the perfect power plant. Here's what you get: our GZR 1.6 full circle crank features a deeper key way channel and less end play so no need to use crank shims. This motor has a stock 36mm oem zenoah cylinder that we cut the combustion chamber on and set the squish at .030" along with our 36mm GZR promod piston it comes with our billet aluminum crankcase and Zenaoh E-Z start. This complete motor comes with a great price run as it is or modify it and you have the perfect 30 plus race motor.
Please note the cyl has no porting other than cutting the combustion chamber for squish setting.If you want one of our 30 plus engines buy this and port it and the rest has been done for you.
Note that we have had made our new 2020 GZR long stroke crank which is the 29.6 crank and has no affiliations with any other engine manufacturer also the rods and bearings our made to our specs no some china cross bred cranks that cost double and are inferior to our new 2020 GZR crank line. Just another innovation from GZR racing
Note: our new GZR crank line are taper cranks and not straight cranks.
