With the chain on, check how much slack is present by lifting the chain up and down half way along
If there is too much free play the chain has to be adjusted by moving the rear wheel backwards.
If the chain is worn it may be necessary to remove a link to achieve the necessary adjustment.
After adjusting rhe chain make sure the rear brake is still within adjustment.
Make sure the front and rear wheels are in alignement with a straight edge when the front wheel is facing dead ahead.

How to keep my gears from slipping


Firstly ensure the derailleur is in good condition and not bent so the chain is running perfectly in line with the sprockets. Ensure the stop screws limiting the extent of the travel of the derailleur are set correctly to prevent travel beyond the first and last sprocket.

A badly worn chain could need shortening or replacing in order to provide the correct chain tension or a loose chain could be a matter of a derailleur that hasn't seen the oil can for a while and is not tensioning the chain correctly.
If the bike has been involved in an accident the rear forks could perhaps need some adjustment so a straight edge laid alongside the main chain-wheel coincides approximately with the middle of the rear sprocket cluster.

At this stage it is also wise to ensure the gear cable is in A1 condition, smooth operating and properly oiled with no internal frayed strands causing problems.

If your gear selectors are of the modern style with detents the gear cable needs adjusting so the centre of each detent at the gear selector positions the derailleur precisely below the selected sprocket. Once this is done if everything else mentioned above is ok the gears should now operate smoothly and positively.

If adjustment doesn't work then the problem is likely to be with the basic requirements above.
Good luck!

Chain keeps sliping, but has good tension.


Web search "bicycle chain slipping" to help narrow down the cause. Likely it is worn chain, gear teeth or both.

Then web search what you noticed.

A great resource....

Hi there I own a Yamaha 1000 thunderace 1998.When I pull away there is a chain sound that desturbs the clean sound the enjin makes when driving.The bike does not miss fire and changes gears smoothly.when...


By chain sound do you mean a metalic rattle when you ride off?
I will assume that is not making that sound at idle. It could be that your cam chain has stretched and needs to either be replaced or tensioned.

If it is a pinking sound, sort of like someone tapping on a tin can with a coin. Then that is most likely preignition which isn't good for your engine. Why octane/RON fuel do you use?

The bike keeps shifting gears on its own what is wrong


This happens when the back wheel is not lined up properly with the bicycle frame. Because the gears are not in a straight line with the chain it can slip. If it slips to the right, away from the wheel, then loosen the wheel and move the end of the wheel next the pedals slightly to the right as you stand behind the bike. If it slips to the left, in towards the wheel, then move the end of the wheel nearest to the pedals to the left. Once the wheel and the chain are in line it should stop changing on it's own.

Chain slipping after changing tire


You may have knocked the gear derailleur when fixing and re-fitting the rear wheel. This can knock the derailleur out of whack slightly and will need proper adjusting by your local bike shop.

My chain sounds like it keeps slipping


It is not slipping unless your sprockets are SHOT.

There should be about 3/4 inch play in the center bottom of your chain when the bike has a normal load on it (read YOU).

Now then, your clutch could be slipping ... have you adjusted it?

I hope this helps you

Im changing head gasket on 1988 mitsu triton 2.6.have the head back on and i had the cam chain wheel under tension but i think it has slipped.i kept the cams and evrything in place nothin has moved cept...


a good idea to keep stuff from slipping is to put zip ties on the chain and cam gears so you dont have to question if it slipped or not,i would recommend finding the tensioner,relieve the tension and see if you can get it back on,it might not have slipped,just when you loosened the gears and took them off,the tensioner went full tension and its probably too much to just force the gears back in place-
