2001 zr 600 carb............. what kinda benifit froma 2 or 3 degree offset key??????? also what else has to be changed to run safe

Well, you can add the offset key but- you have to make sure you run high octane fuel all the time. And if you run at slower speeds for extended periods, you may melt down. Thats what I read in the Black Magic catalog in the offset key section. I bought an offset key and decided to leave it out(020) I might try the 013 key instead.....tigger
