robonfire · 11-24-2007, 01:34 PM

Hi Im haveing prob with my carb. im running my bike (honda cr250 2004 model) on 40/1 petrol mix but im still having oily spark plug also when i stop petrol comes out of the overflow. i was told that it could be that it had a race exhaust on it and when i bought it they tock it off and put the standered exhaust back on and did not ajust carb. if this is the case can anyone tell me how to change carb settings back bto standered as i dont have a manual as clymer and haynes dont have one out for it and the one from my honder dealer is £80 that about $160 to much for me. thanks rob

I think from 2001 one up the cr is un changed other than graphics.
Pull the bottom of the float, there should be some brass hex heads, these are your jets, take them to the dealer and they should tell you what you need to change.
