Re: Warmup

Like Blaine said - that white idle screw is used to set the idle ONCE, after the bike has fully warmed up, to 1200-1300 rpm, then don't touch it again. That is not an adjustment you make every day or every time you ride. You use the choke to start the bike and after 30 sec or so, ride off and turn it down as you go. That's normal operating procedure, for almost every bike that's not fuel injected. Why is that so hard for everyone to understand? Reading the owners manual might help.

Re: Warmup

My choke was taken off by the previous owner, for what i do not know, so i have to play with the idle knob everytime. Once i turn it down to what i think is decent idle i take off and its good for the rest of the ride.

Is letting it sit there for that few minutes really going to hurt my bike? I only ask because I am new to riding. Also, new to manual transmission vehicles. I have never driven a standard car or truck.
There have been cases where people let their bikes idle for long periods of time (like 20-30 minutes) and did serious engine damage caused by overheating. If you ride everyday and you have a warm-up routine, then just stick to it. But excessive idling and wait times are not good for the motor and, as mentioned, can cause some serious problems.

Re: Warmup

RR - replace the choke. It's an "enricher" circuit. (not an air flow limiter like on an auto carb), to enrich the mixture to allow for easier starting. Not exactly the same as adjusting the idle speed.

Re: Warmup

Do you think it will cost alot to replace, and is it very necessary?

Yes, it's very necessary! Check up on folks with parts for sale on this site. If anyone's got one, I reckon it'll be as cheap as anywhere. :2tup:

Re: Warmup

hi all

speaking about idling and chokes..the senerio.. start the bike no choke...2500 rpm..put on choke all the way 4000 + rpm...turn it off goes down to bouncing between 1200-1400rpm... stop at light 2000 rpm....next light 1400 +- 200.. next light 2000. at stop light while at 2000 rpm turn on choke and off rapidly idle back to 1200-1400... am putting greenfoam stuff in tank.. is it the choke or the carb.. remember choke cable was pinched at one time and i fixed it and lubbed the cable....

safe biking

I'm guessing the cable.But wait a few days and let the carb cleaner do it's magic.I have always had the best luck with Sea Foam.
