XR650R Erratic idle problem
I bought a Honda XR650R a couple of days ago, and after a sweet test ride with no issues at all, it's now started having issues with idle speed.
It idles all over the place, usually really high. Sitting at lights, and my bike's revving through the roof.
If I rev it a bit higher, and shut off, it tends to chill down a bit.
It might rev at a sensible speed for a while, then just speed right up.
It can also rev high, then drop down quick and stall.
So I figured it much be something to do with jets or mix or something, and today I stripped the carb down and cleaned jets and anything that moves.
This helped a bit, but still far from healthy. The problem persists.
I've read people online recommending valve clearances, specifically the exhaust. Some folks say it's the throttle cable routing. But no one seems to have any definitive advice, it all seems to be a bit vague.
What can you add to this? Has anyone else had this problem, and solved it?
