liljake Posted October 25, 2016 Report Share Posted October 25, 2016 Would like to know if i can go back to running 93 octane or if i should stay with 100 i do a lot of riding in wisconsin long rides and its a pain in the ass to find 100 up there(32:1 dominator).

ginger Posted October 26, 2016 Report Share Posted October 26, 2016 we will need altitude, compression, and riding temp to see if its possible. Quote Link to comment Share on other sites More sharing options...
liljake Posted October 26, 2016 Author Report Share Posted October 26, 2016 bore 60 over sea level, is mostly chicago area and wisconsin so anywhere from 600' to 1500' i am always on top of jetting it. And being fall time where im at temp wise the weather is bipolar as fuck but ill be riding in 50-65 degree weather. compression is 180-185 Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted October 26, 2016 Report Share Posted October 26, 2016 You need 24 cc domes with that set up Quote Link to comment Share on other sites More sharing options...
liljake Posted October 26, 2016 Author Report Share Posted October 26, 2016 With 93 octane? Or a 100 the way im running it now Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted October 27, 2016 Report Share Posted October 27, 2016 To be honest I would run 110 in what you got without cc it it's close to 14:1 , to run 93 you need the 24's Quote Link to comment Share on other sites More sharing options...
liljake Posted October 27, 2016 Author Report Share Posted October 27, 2016 Ok I just did the top end on it last month so I don't want to change the domes again ill just run 110 for the rest of the season. So if I'm doing that could I up my timing a bit more? Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted October 27, 2016 Report Share Posted October 27, 2016 Crank is welded? If your fuel is good, +7 is about as high as I'd go. Quote Link to comment Share on other sites More sharing options...
