Carburetor And Jetting Database

[90GTVert]

This is a place to list carburetor and jetting setups that have worked for us. Most likely you won't be able to use someone else's tune for best results, but some of this info could give you an idea of where to start or what ballpark you'll be in with jetting sizes. If you would like to contribute to this database, please PM me. Include as much info as you know. Make, model, year, engine platform, carburetor size, main jet, pilot jet, needle setting, elevation, pre-mix or oil injection (for 2Ts), etc... Thanks!
