I have a noss head with 21cc domes and new wesico pistons was wondering if i should go with a hotter or colder plug? The plug i use now is br8es.

I'm rebuilting the top and was wondering if it would be worth changing the head for more compression and power. The motors top is still stock and I will rebuild it that way. So can i just put a head while I'm at it and get more perforance. I don't know what cc size to go with being stock heads and the motor has all the bolt on parts. What kind of pistons do you think would be best and will the noss cool head a good pick.

I ride in N.Y. and compression was 110/113.Cold

Compression was taken with motor cold.

No i haven't ported yet or even got into the motor. I put DG pipes, stage3 jets, power reeds,boost bottle, and KN filter on the bike.

I have a 03 banshee that's never been rebuilt. My compression was 110 and the bike runs well so i was wondering if it would be best to just rebuild it to avoid problems down the road.
