Hi, I have a rmz250 2010. I was riding it for about 10 mins then it cut out and would not start! Then I roll started it and it went fine then after 10 seconds of idle it cut out and would not start again! Then the Kickstarter wouldn't kick down! I changed the oil there was nothing in the oil then it started and cut out straight away@
Having same problem will ride fine when roll started but won't idle or it'll cut out and won't kick over either did u find out the problem ?

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?
