My bike is port and polished (the port and polish is agressive ) and it has a milled head with trinity stage 5 pipies with single K&N filters on each carb. the bike revs out fine when it is in nutrual but when I run it it is fine till I open her all the up. Then she hesitates and bogs any suggestions.
I rebuilt my motor already and put a new ricky stater 200w in it to.
