I am about to get into a 2156. I went aftermarket on the 2159 for the displacement but have a hard time believing anything aftermarket is better than Oem.
With that said, the hyway cylinder I received was very nice. I don’t have enough experience with the 2156 cylinder to comment on power difference. [mention]srcarr52 [/mention] would be the guy for that question.
I did see HL has a meteor made cylinder that might be worth a try… If this 2156 cylinder is toast, I would probably try a meteor or get another hyway. If it isn’t toast, I will stick with OEM….
