2003 yz 125 keeps breaking the c shaped locating clip which is on the kickstart assembly. Not the return spring. Replaced assembly with a completly diff. one kickstarter engaged, bike started. Only rode it for about 15 minutes, then stopped and noticed a chattering sound coming.from kickstart/idler gear area. Now the kick startet is not engaging again, and not returning. Same symptoms as before the replacement. Noticed when I had it appart, that the idler gear wobbles on it's shaft. Wondering if anyone has had issues with the idler gear making contact with kickstarter gear after bike is started, causing it to kickback and break the clip. Any Help appreciated.

Hi!
You obviously look after your machine and very sensible when laying up, however as you are probably aware 2 strokes rely heavily on compression, A. to produce excellent combustion and B. to draw fuel into the chamber. So when you try kick starting you can't get enough revolutions to draw the correct amount of fuel into the cylinder, where as you push start you constantly turn over the engine increasing compression slightly and bingo it fires.
Can you remember how when kick starting it before this problem the feel on resistance when kicking over? has it now become a lot easier? if so you possibly have worn or broken compression piston rings.
A compression test will reveal this, I hope this sorts your query?

It has been years since I have had a bike with a kick start, but I don't ever remember any play. Are you sure its not just easy to move untill you get to the compression stroke?

Yes, there is a proper way to start the engine. Four controls are on your bike to assist in starting.

• The choke, used when the engine is cold. Pull the knob for choke.
• The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
• The de-compression lever, always used.
• The throttle, used to prime the cylinder.
