The piston and rings have to be replaced if you haven't done so in the last 100 hours of riding.

I have 2003 yz 125 it runs teriffic and shift's grate 1-5 but it wont go in to 6st gear . any ideas


Well - you will first have to buy an earlier model to get into 6th gear. The 2003 YZ 125 is a 5 speed transmission. There's nothing wrong with your bike.

I have a 1985 yamaha yz 125 wont start


By what you have written,I take it the motor still turns over.Take the spark plug out and see how much compression you have.If there is very little,it may have been the piston seizing.When they cool down,they can sometimes be moved again.This is the most likely cause of your troubles.If you have compression,take the s/plug out,put the bike in first gear and see if you can turnover the motor AND g/box.What you are looking for is a broken part in the g/box that locked up the driveline.Do this in each gear.Sometimes you can take the pipe off at the head and see into the combustion chamber through the exhaust port.Otherwise the head needs to come off.Hope this helps you

1997 yamah yz 125 lots of white smoke comeing out of pipe


How much was it smoking previously? Too much smoke (oil) is a whole lot better than not enough smoke (oil). If you are mixing the oil and gas then cut back on the mixture. Obviously it is out of balance. Put 1/2 gallon of raw gas in the tank to cut the mix. After a tank or so you should get the balance back.

You need a new shift shaft and probably need a new shift lever due to the bad splines. You can try the JB Weld but I suggest that you go ahead and drill the lever an shaft then put in a cold roll split pin from the hardware store. You have nothing to loose since the shaft and the lever are already toast.

Please rate this solution. Thanks!

Yz 125 2001 stays in gear when clutch pulled in


Lose the Honda transmission oil. It may have swollen the cork on the friction plates. Go with 10w40 in the gearbox. Any major brand; Mobil, Shell, Quaker State, Pennzoil, etc.. Try the new oil and give the cork a week to shrink back down > if they will. You may need to put in a new set of plates.
