this one, i've got absolutely no ideas with....

tis all in the topic heading really.....initially i thought it was the valve clearances, but on taking the tank off and investigating further, i found it to be the carbs....

any hints, tips, tricks?

the bike idles on 1K fine, pulls well thru the range......

so im at a loss, im thinkin it shouldnt be doin that tho....

Kwakas are very ticky/rattly engines. Just what they like to do

Would probably be ebst off just getting out on a ride with some other k's and listening to their best.

One of the really experienced guys like Dave might be able to tell you where exactly on the engine to listen though.

Fingers crossed

i could be wrong here.. but if your carbs and vavles are very close together..


ie if you take the air box off and tried to run it, any valve noise will prob escape via the carb's do to the fact that the carb's are feeding the valves..
Your manifoled is most likely no longer than 2cm, unlike a car, and has a direct throat per cylinder, same as side draft carby set ups in cars running multiple carbs.

As has been said before Kawa's tend to have alot of ticking..
but then again an engine that can hit a high red line at will for 40,000+ k's has to have abit of slack in the top end to take the punishment... I've heard nothing but good things about the longevity of "K" engines as well as them being noisy..

Unless it's an abnormal sounds, that your worried about in i'd just get someone to have a listen otherwise take it in and have it checked next service perhaps.. But I recond you'll find it's the top end ticking away, and the location of the sound is just misleading you...

good luck finding out for certain though.

use a "mechanics stethoscope", i.e. a BIG (30cm long+) flatblade screwdriver. Put the blade against the suspected noisty part and hold your hand around the end of the handle and put your ear against your hand.

This will help you precisely localose the source of the noise to within a couple of cm if you do it carefully. The first time i did this i thought my motor was going to fall apart, but was able to localise the noise,

Remember they are noisy buggers anyway.
