donkeypuncher Posted June 11, 2009 Report Share Posted June 11, 2009 only thing running too high of octane (which is what you would do if you ran 21cc domes) will hurt is your wallet. i can tell you right now that 110 is too much for your bike. but, as for which domes to buy to make full use of the 110 the only way to find out is to do a compression test.

fastrthnu Posted June 11, 2009 Report Share Posted June 11, 2009 most likely its just a waste and wont make it run better, maybe worse. with a 21cc dome you sould be safe with 93 pump gas. at sea level your going to make around 150-158psi fresh, and lower at higher elevations, so,.... yea. If you wish to bump your compression up with smaller domes, then you may need it. Quote Link to comment Share on other sites More sharing options...

Bansh-eman Posted June 11, 2009 Report Share Posted June 11, 2009 what size of domes do you recommond. Dome size depends on what kind of fuel your wanting to run (octane) and what altitude and temps your going to be riding at. Quote Link to comment Share on other sites More sharing options...
diggerzmound Posted June 11, 2009 Report Share Posted June 11, 2009 You can run 87 in your current build. Get some 19cc domes and mix that 110 half and half with 91 and you'll be good. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted June 11, 2009 Report Share Posted June 11, 2009 You can run 87 in your current build. Get some 19cc domes and mix that 110 half and half with 91 and you'll be good. Or get some 18 cc dome and run it straight. It won't hurt running the fuel. If your going to spend the cash on the fuel why not get smaller domes and get a nice midrange boost.

Handyman Posted June 11, 2009 Report Share Posted June 11, 2009 Compression of 160psi is about the area people start thinking about 110 or higher or mixing 50/50...running straight 110 won't hurt anything just isn't needed for anything below the 160 area. the VF3's are a good mod to do....I'd do it in a heart beat...

8buck Posted June 11, 2009 Report Share Posted June 11, 2009 Higher octane actually burns slower than a low octane. So, if you use it but dont need it, you actually lose a little power but it's not harmfull to the motor at all. Quote Link to comment Share on other sites More sharing options...
