Choke....again

[YEN_POWELL]

I had a bit of a sticky choke syndrome again, which only began in the last mile of my journey home on Friday night. As soon as I slowed from motorway speeds to a roundabout I noticed it didn't really want to tickover although the rest of the rev range seemed fine.

Due to family trouble I didn't get to have a look till just now. Anyway, I have removed the cable completely, put the plungers and springs into their holes and used the blanking plugs from the calipers as described here (by Maverick I think). It's ticking over properly again, now I'm off for a few trips round the block to see how it behaves when warmed up.

Funny that I was thinking of doing the same to mine - I'll have to pop 'round sometime for a few clues, hints and ahmm cup of tea

The hardest bit is not losing the spring or plunger into the belly pan when removing the choke or squeezing them back in.....

Did about 2 miles in the dark and it seemed okay. Off to ride to work on it in a little while.

I had to use the choke while I was away, must have been the petrol out there. It wouldn't start in the mornings without some choke. Fine once warm though.

Is there a throttle setting that emulates the choke? Or if you needed to use it would you be stuffed?

Well the 52 mile trip to work went well, the tickover is much steadier as is very low speed running.

I rode my twin for nearly two years with that fix Just check that the caliper bolts don't undo themselves due to vibration from time to time

No fear of that, the salt will hold them in. Actually you forget I have practically got a whole 2nd Africa twin in a box (except the engine, frame and forks, the remains of my 130,000 miler) so I have spare blanking plugs

Well seems okay so far, 120 miles up now. I was racking my brains wondering how the choke could possibly move between the start of my journey and the end of it, especially as I never touch the thing. This morning it came to me in the middle of my ride to work.

Just before the bike started misbehaving my left hand lever/mirror mount had loosened slightly, not enough to move in normal use but at 80mph on a windy day the mirror was acting like a sail. As I went to look in my mirror on that side I noticed it pointing slightly downward and my clutch lever pointing a little upward. I pushed the thing straight but it kept moving every few minutes, I ended up riding with my left index finger pushing gently on top of the clutch lever.

I reckon the movement put a bit of strain on the choke cable. It's a collection of loosely connected joints, any of which can be pulled apart enough to totally change the ration of inner and outer cable as anyone who's removed one will know.

My AT suffers from the same problem, a bit hard on fuel andt it doesn't idle right and it even cuts out after a hard rev or if i pull the clutch in at motorway speeds.

Ordered a new cable but is there anything else that would need repleaced?

Don't replace anything just disconnect the choke, more hassle than it's worth keeping it clean
