Set timing chain ajust valves 110 chinese dirtbike

its probly worn out--thers an ajustment-u can try that----or get a prorepair book on that model----dont keep kikn it--u cud bend a valve from the piston being out of time

www.wemoto.com a Apparently they do a lot of parts for Chinese and Japanese bikes. Hope this helps

not good thing timing belt break most of the time valves will get damaged you might be lucky my timing belt broke on my 1977 vega monza didnt damage valves but i had timing chain break on 98 lumina got valves damaged.

There is no way to tighten chain,there is a spring or plastic tensioner that keeps chain in place.2003 if you have done a lot of riding it may be time for new one.you need to change chain,tensioner if thereis one,and the plastic chain slide that chain rides on.Good Luck.

I'm assuming that you are talking about 1989 Nissan Truck 4WD 3.0L FI 6cyl.

In this models, the Z24i and KA24E engines do not use the pin counting method for finding correct valve timing. Instead, set the timing chain by aligning its mating marks with those of the crankshaft sprocket and camshaft sprocket. The camshaft sprocket should be installed by fitting the knock pin of the camshaft into its No. 2 hole. On the Z24i engine, the No. 2 timing mark must also be used.

Excatly, what is the problem? Adjuts timing procedure?

FIRST THING CHECK THE ENGINE OIL LEVEL!
IT COULD NEED A VALVE AJUSTMENT BUT THAT IS NOT COMMON.
THE TIMING CHAIN ,GUIDES AND TENSIONER WORN OUT IS MORE LIKLY.
IF IT HAS BEEN RUN WITH LOW OIL FOR A LONG TIME THE ENGINE BEARINGS COULD BE DAMAGED

if its a 4 stroke it is prob out of timing or needs a new plug try cleaning the air box and a new spark plug if problem is still there you will need to take it in and get valves set and timing chain checked to see if it is stretched

depends on the geometry of bike-shud be ajusted wen cold-please in vest in a clymer or haynes manual-there detailed with all specs
