Ignore my stupid ramblings, the only bit I say of any use I get wrong due to nearly fainting from the fumes!

The throttle moves cleanly, but the revs don't die down.

If you listen to it when I blip the throttle it sounds like I'm trailing the throttle, but I'm not - i'm straight on it, and straight off again.

Any ideas?

I know at least one of the exhaust downpipes has a bad seal to the head and I know that my air box is not on quite right (with one trumpet not sealing with the airbox)

Cheers for the advice.

i havent a clue sorry but when you take your foot of the accelarator does the pedal return straight away or does it slowly return up

return spring fitted?

yup return spring is fitted, pedal jumps right back up.

cant make out in the vid, are you revving it using the accelerator or the linkage on the carbs / throttle bodies? if is using the pedal try it direct on the carbs / throttle bodies.

i kept getting missed gears on my zx10 as the revs wernt dropping off quick enough, a load of 3 in 1 down the throttle cable and it feels much better and doesn't miss!

Just a thought....
The choke slide mechanism on the carbs isn't in the 'on' position, by any chance?

spring is on the return cable. hmmmmm

Just listened to the video and I reckon that sounds like the carbs are well out of balance so that although one carb is shutting the others are falling off later and holding rpm up. A good balance up[ will crispen things no end.
Hope that helps

Don't forget the cable only controls the butterfly's. the needles are on the slides and diaphrams so if the breather is blocked the diaphram will hold a slight vacuum. jap bike carbs work very much like the old stromberg.

I had a similar problem with my 893 that the throttle wasn't retuning properly. there was about a 1mm gap left between the throttle stops on the cable holder which i could close manually and the revs would instantly go down, fitted a bigger return spring on the opposite side of the cable holder and it works a treat

Thanks guys.

I am sure the carbs will be WAYYYYYY out, I'm also sure a stronger spring will help.

Thanks guys.

It will limp me to an SVA fail which is all I'm after.

I'll sort all this after I have 6 months grace
