Fist Time Rider - Issues with Idel and Throttle
Dude
P, OK- it's time(not to sound rude) to start reading more,(threads of your concern),and asking less. If you look, or dig(use the search engine), into this forum you'll find every answer you can possibly imagine. I enjoy helping when and where I can, and I'm no expert, but you really need to familiarize yourself with this machine through the information that is already posted. I only say this because I got a little "beat-up" when I started on this forum. I hope I'm not off base with this comment, and I mean no offense.....................D
Don't give up. There are several potential causes listed already, rule them out one by one.
Remove the air cleaner and look at or feel the slide moving to see if it does in fact bottom out. If a flashlight and inspection mirror won't allow you to see it, stick your finger in it. This will rule out throttle, cable, or mounting torque issues.
As far as the possible reason for an instant change in idle speed, a likely cause could be dirt in the carb, even if it has recently been cleaned.
The jets and passages in the carb are very small and the slighest bit of dirt, slime or debris can easily stop them up, especially the slow jet.
Take the carb apart and clean it with carb cleaner and compressed air, make sure you can see light thru the jets, especially the slow jet.
If you don't have a fuel filter in the gas line, it is a good idea to install one.

Fair enough. I'll searched several times though older post but I should spend some more time doing so. With little knowledge of the subject and an over whelming desire to begin riding, I suppose may have relied to heavily on questions. I now at least have great starting point. Thanks again for the help.
I'm in a very similar situation. I have yet to get my bike reliably running, but I'm getting closer by trial and error. LOTS of error. When I knocked off for the day I got the bike to idle at a more reasonable level but after about 10 seconds of purring it'd suddenly and without any influence on my part surge and roar then stall out.
I have a question regarding the throttle slide and 'bottoming out'. My throttle seemed a touch sticky and when I'd get my bike started it would idle incredibly high then stall. I took the carb off and made sure the throttle slide wasn't sticking. It seemed to move freely but at 'rest' it stopped what I'd call maybe a half inch from the carb 'floor'. Try as I might I can't find any pics that show where the slide is supposed to sit when the throttle is not being engaged.
I have yet to degrease my assembly under my handgrip; it seems to turn freely but it IS coated with heavy grease.
