You should be able to buy those jets at any HD dealership. If they ask what it is out of tell them it is from an HSR42 carb. We know it isn't but the HSR carb jets will fit. If you tell them it is from a Yamaha with a Mukuni BSR40 carb it will confuse them and they will say they can't help you. Edit: I will check to see if I have either of those jets, if I do I will send them to you. Edit,edit I just checked my jet kit and don't have either of the jets you need. My selection is getting pretty thin.   Logged     Last Edit: 2017/06/28 06:39 By davej.   dave   The administrator has disabled public write access. #1015526 Engineman (User) U.S.S.

I wouldn't be hitting the rev limit in neutral. that isn't checking anything. Put some Seafoam in the fuel tank and go for your weekend ride. It will be OK. As rich as you were you probably got a lot of crap to blow out of there.   Logged     dave   The administrator has disabled public write access. #1015608 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:Hypercharger bike is running to rich fouling plugs 8 Months ago   It'll always throw raw fuel banging the limiter in neutral. There is no load on the engine and you are whacking it with the accelerator pump every time you do that.   Logged       The administrator has disabled public write access.
