Misssppelllleddd Posted February 15, 2008 Report Share Posted February 15, 2008 What type of fuel should I get for certain sizes of domes? I ordered 19cc domes and wonder if I should get higher octane fuel or not. What are the smallest domes I could get for 93 octane fuel? Any help would be appreciated.

Fuel is gonna depend on your compression. We need to know if your ported, and your elevation. If your per say stock porting at sea level, then your going to need AT Least 50/50 110-and-93 octane fuel. Quote Link to comment Share on other sites More sharing options...
Misssppelllleddd Posted February 17, 2008 Author Report Share Posted February 17, 2008 I ride about 750-800 ft. above sea level. I have stock porting. Quote Link to comment Share on other sites More sharing options...

Your going to need at least 100 octane with those domes, you will be around 165 to 170 psi at your elevation. To run 93 you will need to order 21cc domes.

BansheeRider71 Posted February 18, 2008 Report Share Posted February 18, 2008 20 or 21 cc domes is all you can do on pump gas, you might be able to get away with 20 cc domes for pump gas, 19 an below you have to run race gas. Quote Link to comment Share on other sites More sharing options...
