Hello all. Ive been trying to fix a common problem with xs400's. High rpms at idle. I've read and tried so many post suggestions to no avail.ive read this morning the it might be athe pilot jet size ao i took it out and it says 42.5 so its correct. The only this is when i google 42.5 pilot jet for bs34. Its different that mine.they have holes in the side and mine has one tiny hole in the bottom. Heres a pic and its a 79 xs400 d i beleive.
Thanks...glen
