350x is too rich

[toyvette81]

i just bought this bike, it would barely run on full choke the main jet was halfway clogged and the idol/low sped jet was 100% clogged up....... so i got it running great, & today was my first real ride on it besides up and down my street and it is running too rich, it fouled the plug within an hour. apparently i had it cleaned out enough up and down my street, (it's about a mile long ) but it does have some rich smoke when i get on it at the beginning of each gear, i generally know that 2 to 2&1/2 turns out on the mixture screw is a good place to start, does anyone know any different on this bike, i have not messed with it on this bike, i have only cleaned all the jets. or is there anything else i can do to lean it out. if anything i would have figured it needed a 142 jet b/c of the DG pipe which i suspect has no packing or baffles but i guess not.
help me lean it out if you can
thanks

take your air box cover off. See if that helps

With stock filter, and DG, 140, with k&n and dg 142. What main are you running now. If its above 142 then its probably rich, if its not i highly doubt that its rich.

it has a 138 in it, i have not studyed it though. no 1 says that it hasn't been drilled out...... i figured 142 should be what it needs also, thanks
