The accelerator pump is rarely adjusted. The procedure is in the manual, and involves measuring the distance to the pump rod from the throttle arm. I would guess that any adjustment that is done probably won't dramatically affect the bike's operation. The only time you may notice would be less of a stumble when the throttle is quickly opened.



Why do you think yours needs adjusting? Carbs off would be easier if necessary, but you might be able to at least check with them on.

i think the accelerator pump needs adjustment because i'm pretty sure i adjusted it unaware of what it was. when i twist the trottle even a little the rpms soar and don't come back down for a few seconds. i thought i was too rich but seeing in the fsm how that pump operates i think its engaging too soon.

Check for air leaks mike at all six joints, you symptom is classic for that. Do you have your air filter in?

Abe, I think I remember that he is running 120/156 jets, pod filters, and straight pipes with no baffles. Maybe the vacuum piston is hanging up too. Who knows when things are so non stock.



The accelerator pump would not be the cause of this tho.
