locogato11283 Posted July 4, 2005 Report Share Posted July 4, 2005 i think you could prolly squeeze by with 20cc and pump gas. here at 1000 ft my brother ran 18cc domes and pump gas for a year with no signs of wear at all.. Quote Link to comment Share on other sites More sharing options...
Banshee~ Posted July 4, 2005 Report Share Posted July 4, 2005 You should can run 20's at 1000 ft with no problems. Quote Link to comment Share on other sites More sharing options...

Rare Scottish Tree Badger Posted July 7, 2005 Report Share Posted July 7, 2005 what are stock size cc's anything beter then stock id go with.. peace devin 389838[/snapback] Stock is around 24cc ... Standard compression on a 'stock' bore is around 135psi @ sea level. The 21cc dome will give you about 155psi and 20cc about 165-170psi. Rare.

Stock is 22-23cc domes. Quote Link to comment Share on other sites More sharing options...
Rare Scottish Tree Badger Posted July 7, 2005 Report Share Posted July 7, 2005 so will i be all right with 20cc?? 389846[/snapback] You'd be safer with 21s unless you're spot on with your jetting. ... They'll give you some space to add a few more bolt-ons without risking detonation. Rare. Quote Link to comment Share on other sites More sharing options...
BANJO Posted July 7, 2005 Author Report Share Posted July 7, 2005 21cc's it is.. thanks.. devin Quote Link to comment Share on other sites More sharing options...
