what to do ?

now i nead info ;(

it looks like cam timing is lost and i dont know maybe fire time is bad to

so first i turn engine til TOP DEAD CENTER (TDC) on mark T I F on red mark
then i fixs ex cam ,then zi5 mark on cam , then valve cover, tensioner installed .

after is still not working and does not accept the throttle

maybe is chain was over jumped , but if i loosed cams and i readjusted them. its should work.

new coils. carburetor is clean. compression is its poping of finger .and still 4 cylinder is not hot like other 1.2.3.

Alright, let's start with cam timing since that is a question. (The tensioner housing was broken and repaired somewhere near the beginning of this thread.)

Check the timing again, like on the drawing you posted from my website. (I'll repost it.) In order for the camshaft marks to line up, you must press down on the chain in the middle, like the drawing shows. But make sure the tensioner cap is off and the crosswedge is loose before doing that. Try to post some photos so we can confirm.

halo here is all pictures. and video
1, i rotate on mark TIF
2. fixed ex and e/5
3. valve cover new gasket
4. tensioner
5. after starting is same and now its not working cylinder 4 its cold . u can look in video

bad sound ore now sound



video :

and video after i start the engine.and u hear through the carburettor fired back small noises :

Does it get hot when you rev it? Pics of plugs?

The cam timing looks good, as long as the pin count is correct.

And yes, the arrow on the #8 cap should point forward like the other caps.

So it is definitely #4 cylinder not working. Did you double-check the valve clearance while you had the cover off? What were the clearances?
It would be best to rule out the engine before moving to the carbs (ignition coils already replaced).
So you may have to get a compression tester.

hi again
i did not check the valve clearance. i can try tomorrow ,its only i start to be very tired of taking off the valve cover ......

and maybe i will find tool for testing the compression .i thing it will be the problem because i can find why its not working..

thanks for help and can u write info for valve clearance checking ,in manual i jus find how to test ,but how many millimeters is ok and what is bad.

and next weak i try to show my kz550 to mechanic in other city. i hope he can help to .

thanks again .i am hopples but i try i want to ride on this nice kawa

sp i buy compression testing tool spend 19 euro . and all cylinder is :
cold :
1-125/9
2-125/9
3-120-125/9
4-125-140/9-12
warm up engine

1-125
2-125
3-125
4-125

and i tace out spark plugs it was interest why 3 cylinder spark plug is bend its all same spark plugs.

maybe ignition timing is bad? ?

Make sure you have the right plugs (not familiar with your year) ..... and the gap looks to be too wide on the 1 and 2 plugs then too tight on the 3 and 4.

Those are the correct plugs but they should be replaced.


There are many guides for checking valve clearance. The most recent:

You need feeler gauges.




On plug #3, is the ground electrode contacting the center electrode? If so, that is your dead cylinder.
