Revs not dropping when you pull in the clutch when warmed

Sorry Wayne, I was waiting for the punch line!! I'd check and lube cable for free play, lube both cable and anything at the ends that move, especially where anything come close to engine or other heat source. Does it happen when trying to rev when stationary or only on gear changes?

 

We always expect a punch line from you Wayne

 

Some expansion in any intake rubbers that are nearly hanging off if you get my drift?

 

Air leaks on the inlet rubbers or a gripping throttle cable when the bike is hot?

 

Ah that's what I meant to say

 

Is Penelope a carb or EFI model?....if EFI, could possibly be "over fueling" when hot ?....I am by no means an expert, but I did have the similar thing happen on Landy, and it turned out to be the ECU had got "confused" and had to be re mapped.
But as said, and hopefully, it is just air leak or sticky cable.

 

Probably not much help but I'm thinking choke and/or throttle cable free play is not enough. Cables need oiling or are possibly starting to fray a bit. Tickover speed set a bit too high - should be around 1,000 rpm(+/- 50). Muck in carb(s) causing sticking etc (try Redex or similar in petrol to clean 'em out - works for me!).

 

Good advice from stevethegoolie - used Redex on the Bonnie and Trident. Check the choke cable as I had the revs rise on the Trident and it turned out to be a broken choke cable, which caused it to stay on. (thread on here somewhere with pics).

 

if it is the choke sticking a bit you should be able to push it in manually, you can on a sprint anyway. it is a small lever on the left of the bike in front of the carbs, you will see the movement if you operate the choke while looking just under the tank. i would think poss an air leak tho

 

Are the diaphragm rubbers in good condition Wayne? The ones on my Bonnie had gone soft and had lost their elasticity so replacing them made a big difference. (even though that won't be the cause of this particular problem).

 

Hi Wayne or can we call you Parker from now on you joker, you have had some good advice here but if I were having a fast idling problem from cold I would be heading for my spray oil can and would spray around me carburettors and if the engine idle alters there must be a air leak a simple test not much work involved

 

Those rubbers are an absolute bugger - done it twice on the Trident.
