cmyyard19 Posted November 19, 2003 Report Share Posted November 19, 2003 I just bought a trinity stage IV pro head, and the place had either 19cc domes and 21cc dome. I'm right At sea level and running 94 octane, should I go back and buy the 21cc domes? Quote Link to comment Share on other sites More sharing options...
dlnoss Posted November 19, 2003 Report Share Posted November 19, 2003 I would run the 21's. Quote Link to comment Share on other sites More sharing options...
Blue Duece Posted November 19, 2003 Report Share Posted November 19, 2003 Thanks Duece... yer welcome Klotz........in my opnion race fuel will make a bike that doesnt need it run better and a bike that does run great....for the sake of arguement we should all be running the good stuff Quote Link to comment Share on other sites More sharing options...
Blue Duece Posted November 19, 2003 Report Share Posted November 19, 2003 I would run the 21's. i would also run the 21's, if your set on running pump at sea level 20's would be the absolute smallest dome id run, or go for the 19's, they will feel better than the 21's but then id go for 100% race fuel, better safe than sorry, your bike will run better, top end will last longer, i wouldnt go more than 170 psi with out welding my crank though, that couple of psi isnt worth a twisted crank Quote Link to comment Share on other sites More sharing options...
Chemical Castration Posted November 19, 2003 Report Share Posted November 19, 2003 Actually what I learned in that whole RKT scandall a long time ago is that you don't raise your compression to run race gas but you actually run race gas to run higher compression. All race gas does is help prevent detonation. There was a good link that somebody posted I'll try to get it. Quote Link to comment Share on other sites More sharing options...

Lefty, Lefty, Lefty, before my next comment can i just start by saying "i love you man" ..........treat yourself to a tank of 110, then dump some 91 in her, tell me if you dont feel the difference.....thats a damm skippy article too.....if i couldnt feel the bike just running snappier id buy into that Quote Link to comment Share on other sites More sharing options...
