All,
Wanted to run something by everyone to get some information. During my choke cable assembly process yesterday I noticed something I felt was a bit strange. Still in the learning process for this bike...I noticed once the cables were hooked up and adjusted, while applying the choke thumb lever at the handlebar location I noticed the lever would not stay at the "full choke" location and wanted to creep back to approximately the 1/2 choke position with no "notch" or "detent" position. Is this correct? (81 R65). I disassembled the lever mechanism and noticed a small ball bearing pressed into the bottom side of the thumb lever that seems to ride along a recessed gutter section in the housing. Is the lever supposed to have a detent or ratchet notch restriction in it to stay in the full or 1/2 choke position?

The 'choke' lever, at least on my '81, won't stay at full choke it springs back a bit , you need to hold it there.
There should be a noticeable half choke detent .

Thanks Bob, I must have a worn housing since I don't notice any detent even at 1/2 choke, although the lever seems to drift back and hold it's position at the 1/2 point. I'm guessing there should be a small port or notch for the ball to fall into which I can't notice in my housing after a close inspection yesterday. I'm thinking I can live with this. Thanks again for the reply.

My '81 R65 plays nice with the choke lever. The '83 R65, well, you gotta hold the lever in the full choke position. Both run so well that I ain't gonna mess with it.

Solved this choke lever detent problem (dummy). I often wondered what this little curved metal piece with 3 holes was lying on the floor months ago. Had this strange suspision it was important and couldn't get myself to throw it in the garbage. Glad I didn't.

Yup, that could do it!
My 82 will tend to stay on full choke (but not always) if I really pull it over, but mostly it eventually creeps back to half position and snaps/stays there until I close it. My 88 R100RT behaved the exact same way.

You guys with the handlebar mounted choke have got it easy being able to pull in the clutch and operate the choke lever with the same hand.
I could use a 3rd hand to operate the choke lever on the air filter housing. It does stay put though.
