Revs don't drop!

[threepot]

I've noticed recently,the revs are slow to,or don't drop between gear changes. Bike settles to a nice idle,and runs great otherwise. Could this be a diaphragm issue?

[tonytiger]

Could be that or jets. Dose the needle flutter when reved

[Sin_Tiger]

A few possible culprits. I would check the throttle cable first. Then the choke slider before ripping into things.

Can't say ive noticed?

I've checked free play on cable,but its been a while since I've lubed it,and carb linkages,so I'll try that

[Sin_Tiger]

Choke slides don't get a lot of use or attention and I've come across it myself, similar symptoms but it's something that's easier to see and eliminate, which is why I mentioned it.

The inlet rubbers too TP, sounds suspiciously like an air leak

Thought of that,but they were replaced 3 and a bit years ago,when I bought the bike. Worth tightening clamps though?

If it's not popping it's prolly not leaking

I was able to check the diaphragms/slides with the carbs on the bike, careful with those tiny o' rings though

  After giving this some considerable thought so as not to rush in with a bogus diagnostic I am inclined to agree. It's carbs related


Is it fixed yet? What was it?

[threepot]

Well,fitted new plugs,and gave carb assembly a good soaking of Pocket Rocket(like wd40). Cleaned and sprayed all coil connections with Ac50. Bike fired up straight away! I'm convinced the tt600 coil conversion has made a noticable difference in starting? Looking forward to a ride tomorrow   Will let you know if the rev issue is sorted?

Big improvement I'm happy to say! Combination of new plugs and a good soaking of Pocket Rocket..much crisper throttle response low-down  . ID noticed that the idle adjuster had stuck a little,so give that a good spraying. I'm sure that effects running if not lubed enough?

[JayDub]

That shouldn't affect the running TP, just the tick-over speed adjustment... do the revs drop as they should now?

[threepot]

Tis better,but there is a 'little' hesitation when accelerating off,but its hardly noticeable. Bike still pulls strong! Hey,this bike is 20yr old! Had a great ride today around Llyn Brianne dam earlier,and thought there were not many other bikes I'd rather be on  :icon_wink: Even took it off road!
