Thanks for the responses. Little more info on the bike. The entire engine was sent out to CT in the mid to early 90's, they did the head studs and mild port work it was supposed to be set up for trail riding, fast fire roads. The factory carb was worked over by CT also it is a 43B00. I do run full throttle on the flats and gravel roads. So that being said is the Paul Turner pipe good with the right silencer or should I start over? Kind of on a budget, this thing needs a lot of parts.
