[quote][b]Ryan314 (7/15/2007)[/b][hr]I am soooo tired of this! My 97 YZ 125 has a brand new top end and the bike runs absolutely fantastic, no problems when riding whats so ever, never fouls plugs, very crisp, it's perfect. But, every friggen time I go to start the bike up the next day after riding or whenever (overnight, 2 days, week, whatever) it fouls the plug. I always shut the gas off too. It will start up first kick, but after a minute or so, it will bog out and die. I tried shutting the choke off immediatly after start up, but it still bogs out. So I have to change the plug, then it runs great. What is the problem here?!? I just can't see it being a jetting issue because the bike runs absolutely fantastic. I run Yamalube at 40:1 and use a BR7ES plug.

Please help me fix this problem!!![/quote]

do you shake the crap out of the bike before starting it. is the pre-mix isnt mixed up... you'll get alot od pre-mix and could foul it out. i would let the choke run alittle longer.. and always warm the bike up before shuting it off!!!

Try cleaning your jets or jets are dirty.
