look at the top of the piston. all the little dings and sctapes what is that?
 
its running a little sich the plug is dark cardboard and im runnin 110 i might put anoter gasket in se if that helps i thought it looked like pre det but i dont know for sure cuz another sign of that is on the plug little metal but there was none
 
i was told bye the guy i bought it form and the guy who designs the cylinder and head to run 110 cuz it has so much compression if i dont run 110 i run the risk of blowing it up
 
this is a fire breather NEEDS race gas this bike has the head cut to the max and it doesnt matter if its stroked and bbk that doesnt rase compression its the head i could have a stock jog non portede blaster runnin on 110 because of the head mods,
 
dump all that old gas that's got the octane booster out and just use straight 110. theres NO reason to run octane booster with something that needs race fuel. have you advanced the timing?
 
you can run race gas in anything....its just a waste of money if you dont need it and you may lose power

with 180psi you prolly need it

does the head look similer to the piston
