Hi! I have to use choke every time I start bike, how long should I have it out? and how long should I have the motor on before I drive? Cheers [Non-text portions of this message have been removed]

The length of time you need to leave the choke on is dependent on the temperature. I start riding right away and can usually turn off the choke completely within about 1/2 mile. Paul Streeter --- In DSN_klr650@yahoogroups.com, "Johan Brunius" wrote:

My opinion- You should let the motor idle for about 60sec so oil gets to the cam bearings, before you rev it at all. Then drive away as soon as practical. The choke depends on weather. Usually only a minute or so, sometimes if I am careful with the throttle for the first few minutes I only need the choke to start.

"After" I bought my KLR the salesman had lots of good things to say about the KLR. This is a local Kawasaki dealership in a relatively small town with lots of repeat business. The staff seems knowledgeable and races at the local track on Friday nights. I only mention this to emphasize these people actually enjoy motorcyling and not just selling them. Bill (salesman) said the biggest mistake people make with the KLR is not letting it warm up before taking off. So I've always let my KLR warm up; probably more than I should. I let the needle get about 1/8th to 1/4 of the way up before riding. As far as the choke goes...I don't leave it on any longer than necessary. Matt wrote:

Clean, now. A bit of gunk on it before we painstakingly cleaned the petcock, screens, and tank itself a few thousand miles ago; but that didn't really change how the bike ran. Shortly after that we _removed_ the inline fuel filter we'd added because we were concerned it might be restricting flow; that didn't make much difference either (or, at least, replacing that missing spring in the carb made a lot _more_ differenec...) We didn't replace the vacuum hose (we did replace the fuel hose when we took that inline filter out). I suppose that's worth a try.

This bike did have one decided oddity before we added the missing spring to the carb -- it would start happily with no choke. I think that's gone now though; Eric can say for sure, I've been a bit occupied with the latest installment of my doohickey troubles! The old plug was _filthy_ with carbon deposits, unsurprisingly enough, considering the coasting enricher was stuck open. Thor
