Only if you want waste money. Compression not high enough to really run higher octane fuel. Stick with 93 pump gas and you will be just fine. Looking for more power get port work , 4mill crank, vforce4 reeds or better yet a 421 cheetah cub
That was some very good advice and knowledge you shared there brother. Thanks for the advice and I will definitely look more into this before I think about attempting this.
I have a 421 Cub engine I’m building and I wanted to know what are the difference between the thickness of the gaskets. What are the different sizes for? I have a .012 thickness gasket and a .020 thickness gasket.
I have a set of stock 66mm bore dune ported cylinders for $200 shipped. Ready to bolt on and go. Also have a set of and a Pro Design Cool Head that I can throw in for another $100. If interested let me know. Sent from my iPad using Tapatalk
