Question about 2003 HM CRE 250
I have an 06 cr 250. I used to mix my fuel at 32:1 and it ran fine for a year or so as of late it's been fouling plugs every single ride. I've ridden 2-strokes all my life and know how to ride the powerband but lately its been spitting oil out of every seam in the exhaust. It used to maybe have a couple drops after a ride out the end of the pipe but now its leaking from the connection from the case, the pipe to muffler connection and a lot out the back of the muffler. i switched to 40:1 about a month ago and that's what is happening, i couldnt imagine what it'd be like if i left it at 32:1. I took the carb out and looked at my jet sizes, they are both a size smaller than stock. Any help? Also, the bike is so tempermental that I have to have all my gear on when i start the bike because I cant take my hand off the throttle for even a second or else the bike will foul the plug and die literally within 2 seconds. I know they arent meant to idle but its kinda extreme. my friend has a 2005 cr 250 and mixes 32:1 has no problem, can start his bike on the stand and walk away from it for 5 mins and put his gear on.it'd idle for at least 10 min before it'd die, but he'll kick it and it'd start right back up. I've heard running bean oil would help, but I've also heard it has a tendancy to seize up the rings? any truth in that? ,I would try more gas in your mixture, before you start changing everything. Its all in the way your ride, some people can do 32:1, some 40:1(me), some 50:1. ,,,
