when you sent power to the primairy, it started again...
did you check your tension after that? if it's back to where it was before the adjustment, i think your tensioner is broken.
Talked to the buell guy at a HD shop and he said the sound might be normal with this year of bike and with 10k miles. But the best advice he was able to give was to check my plugs and go back to stock along with check my spark plug box.
My idle is set at the stock 1000rpms (when its running right.
The only thing ive done to it when it started this was change my plugs and i put screamin eagle plugs in it.
ALso i did a TPS reset and it does seem to be running better but i dont think that was the problem. Im just going to put new stock plugs back in it, or whatever plugs you guys recommend.
