So you have done all that on a standard jet. start of 10 higher. eg if it was an 86 go 96. Then do some plug readings. If you done all that on standard jet you may seize you motor!
the exhaust was all ready on wen i get the ped it ran fine with it on dun the rest since so i dont fink it will be completley standard
