no you dont have to re jet, but id just buy some 19 or 20cc domes and keep the cool head.

 

whats your mods and current jetting ? your profile is to many clicks away

You'll need to run higher octane fuel, w/the added compression from the 18cc domes. Too low of octane and you will deto. You might be detonating now already, and that might be the reason your getting an engine brake feel on top end.

X2 on this. What kinda gas are you running. I'm running 18cc domes with a FAST port and I run race gas which is a must in most situations. As stated earlier try some 20cc domes getting rid of the head would be a mistake IMO.

pump gas 93 plus i think race gas is to much for my riding style.ill rather bring down the compression.but what domes should i go with.like i said i love top end.and were do you get race gas at now these days.

Get some larger cc domes. Might be able to get away with 20cc domes since its drag ported. Your compression too high for pump gas.
