mx_razzozz_yzf250 Posted June 23, 2007 Share Posted June 23, 2007 So i went up to an YZF250 this year and the bike has frome the start been really hard to start. The kickstarter is very hard so when im kicking i need to kick on it sometimes. What can be the problem whit the bike ? Im really new to 4-stroke bikes so im i need of help. And when its warm its nearly impossible to start and that sucks when im in competition cause i have ben forced to quit two races because of this problem. Ive tried to use the compressien leaver but it dosent help very much i just kick to the point where the kicker gets stone hard. I hope you understand or else help me so i can explain it properly. Greetings Link to comment Share on other sites More sharing options...

Greetings Feel the kick lever getting harder, this is when it is on compression. depress the compression lever so the piston goes over TDC. let go of compression lever and jump on the kick start. try different amounts of choke and twist grip when engine cold. No choke hot. could also be flooding the engine and creating a hydraulic lock with the fuel. ie over fuelling the bike Link to comment Share on other sites More sharing options...

How far down should i take the kick when im holding the compression lever ? And when i lets go of the compression lever should i kick directly or let the kick go to the starting position again ?
