Hi all,
I just bought a new 2001 Cr250, and it has been nasty weather lately, so I havent got to ride it much except up and down the street. in doing so, I noticed that there seemed to be considerable bog in the lower to mid rpm range, then hits the band hard. I have herd these bikes can be tricky to jet, so I was looking for some help. first of all, anyone have any tips and tricks for getting the carb out of the frame? I worked with it for a while, and getting the throttle cable unhooked seemed to be a huge pain. anyway, I checked the jets, and I have a 400 pilot, and an s-9 slide I think it is called. havent been able to check the pilot or needle position yet. I am also not sure which screw is the air screw, is it the tiny brass one, with a locking nut around it? I am looking to do mainly woods riding, and the bike has a fmf sst pipe and silencer. my elevation is about 1000 feet, and the average temps now are about 30 degrees. if anyone can give me some pointers on how to get close, so when I go and jet it myself, I am close to where I need to be, that would be great.
thanks in advance,
Jim
