I hear a clunking fron the front chain sprocket . I think the chain needs adjusted on my 1995 kawaski zx1100.

Hi Jake if you have the right tools it will be no trouble. Before you remove the rear wheel remove the front sprocket cover and loosen the nut or nuts holding the front sprocket. This will be safer than doing it with the r/wheel off. Next remove the wheel and keep note as to where the spacers go (don't mix them up!) remove the sprocket nuts and the sprocket. Again note which way the sprocket goes some have a thinner center so make sure the new one fits the same way. Refit the wheel leave it loose and loosen the adjusters allowing the wheel all the way forward. Then open the chain and join the new chain to the end of the old one with the link supplied then pull the old chain until the new one is fitted. Next join the new chain together. ( you may need to remove a link or two) it will depend on the length of the new chain. After this fit the new f/sprocket and tighten the nut then adjust the chain leaving 1.5inches of free play up and down. Make sure the adjusters sre even on the marks each side. And finaly After a day or two of use adjust again to around 1 inch up and down. Have fun. Regards Jim...

Replace the sprocket - broken or worn teeth can slip and cause your symptoms. If this has been going on for a while consider replacing the front sprocket and chain as well.

Check back lash on thermo fan ie is there side to side movement in the fan if there is it means your thermo fan requires replacing as the electric motor bushing has worn out

My first check would be the condition of the chain and sprockets. Check to make sure all of the teeth are still ok and if the tension of the chain is correct and that it is well lubed.

If the noise is more pronounced from the rear and chain and sprockets are ok, it could be the differential that has either failed bearings or damaged gears.

Thanks for the inquiry!
From your information I can't tell if this is a off-road bike or a street bike. With the extended swing arm I'm suspecting off-road. In either case it's very much same issues. You have two issues and we will deal with them separately.
Chain catching sound:
In low gear when you have maximum torque applied to your rear sprocket & wheel many times the primary sprocket (smallest one under the engine side cover) will slip and actually jump teeth. You indicated this is the third season, so it's seen a lot of wear. It would also explain that when you adjust/ tighten the chain tensioner the noise is gone as the front sprocket is not slipping in the chain. If this happens a couple of times the front sprocket is ruined. Pull the front sprocket cover and inspect the teeth. The teeth will be smooth and ground away if this has occurred. Most off-road riders go through 1 - 2 sprocket and chain sets per season with the abrasion form the sand and mud if they are serious about their riding. Replace front sprocket or both sprockets & chain.
Other possibilities are that you have lost your chain guide or the plastic wear plates inside the chain guide are gone and the chain is banging against the metallic sides or your swing arm making the chain jumping sound you have described. Replace the guide or wear plates to solve this.
Whooping sound on front of bike while coasting: This familiar sound appears to be related to your front wheel. The best way to test this is to set your bike on a bench, crate, or test stand so the front wheel/tire is off the floor/ground and spin the wheel. Your rim may be bent allowing the tire to rub against the fork tubes or front fender making the whooping sound. The engine noise drown's it out under power but noise is audible when coasting with the clutch in and engine idling. The simple fix is a spoke tightening and adjustment to properly true the wheel. You will hear if its a bearing or something else being rubbed against by a wooble or something out of round (run out) causing the whooping sound.

I would have a look at the wheel bearings. Take the chain off and spin the wheel, that will tell you where the problem is.

The front sproket normally last for a very long time so I am pretty sure it is not the cause of this problem.Try to adjust the chain tension and this may solve this problem.Also if the rear sproket are worn out or it could well be the chain that needs replacing.Hope this gives you an idea.

usually kawazaki zxr 400 has these problem the main reason is due to the overspeed.only authorised kawazaki dealer can solve it.....

the chain type is 428. take chain off and count # of links.give those 2 #s to parts guy. when you replace a worn chain,the front and rear sprockets should be replaced at the same time, because worn sprockets and a new chain will cause accelerated chain wear. count # of teeth on sprockets & give those 2#s to the parts guy also. if you want a longer wearing chain, buy one w/ the highest tensile strength,once again, parts guy can help you find that.dont forget,lube & adjust chain as needed.

Well i dont think the ride hieght will change, nothing you could notice, and if your changing sprockets its best to do both and a new chain, now i might add that it is preffered to change chain with sprockets not required if the sprockets are ok. As to the length i can only say i run the 17 tooth around the city and for the long trips i swap back to the 18, mind you it is a new 18 not the original, of course with the change back (2nd time) i have not changed the chain and have been running the same chain length, it has shortened the wheel base from the original 18 tooth front, but i kinda like it a little shorter, gives me more weight over it and the front gives more feed back, but thats just me, not saying its right
