SKEETER Posted November 18, 2020 Report Share Posted November 18, 2020 I'm juzt a dumbass oryguniun. But why would you want 182# compression on this motor. I'd think swapping to lower compression domes be a decent idear Quote Link to comment Share on other sites More sharing options...

SKEETER Posted November 18, 2020 Report Share Posted November 18, 2020 It's not a race motor, I would think 150/160# would be plenty for you. If you want to run less expensive fuel, just get a new set of domes that will work for your setup. Quote Link to comment Share on other sites More sharing options...

Im ok with running race gas, I just want to know if I dont have another option, can i run 91? And the engine isnt completely broken in yet Quote Link to comment Share on other sites More sharing options...

SKEETER Posted November 19, 2020 Report Share Posted November 19, 2020 Something is off if it's a true 21cc dome with that high of compression. Quote Link to comment Share on other sites More sharing options...
