I've got a 40 pj on the way but it hasn't arrived yet. Ref the plug chop that's what I'm doing. I'll do it again over the weekend. Honesty I just want it running nicely on the trails, easy to start hot and cold and safe in terms of not being lean. I've lots of 4 stroke tuning experience...

OK, so I bought a load of genuine Keihin jets as the jets in the carb were unknown age and brand. Fitted a 45 PJ and it ran terribly, back to a new 42, better but still sputtering at very low throttle constant speed. Now back at 38 and it's better again and seems to start OK hot or cold. Still...

Thanks. It's better with the 42 PJ than it was with the 38, so I'm guessing I'm going the right way. The stutter is very obvious and constant. 30-35mph in 3rd is terrible.

Thank you. I'm now waiting for more jets to arrive. I've ordered all sizes from 170-185 mains and 40-48 pilots. My other bikes are all in that ball park anyway so they will be useful for those anyway. The carb float level seems good and the floats are aligned. It doesn't leak at all if the fuel...

Thanks again. I fitted a 178 main this morning before going for another ride. I've now marked the throttle in 1/8 increments on the grip, so I can see exactly where I am. At a steady speed in 3rd gear with the throttle barely cracked its stuttery - so lean? From a steady speed in third with...

Thanks. :) I should have stated I bought a used carb as the body on the one on the bike was really worn, both the needle jet and the float pin hole. :) the replacement looks OK, but I will check it again.

I'm sure I posted quite a bit here last year, but must have been my imagination. So hi everyone! I'm based in the UK and last summer I picked up a 2001 EC250 project which was in a poor way. It was burning a lot of transmission oil and had been used as a farm bike for a long time. It ran, but...
