07 cr125 mod

I have a couple questions if anyone's really familiar with modded 2 smokers

What you wondering about brother?

Might make sense to just ask your questions rather than drawing out the whole process.

Yeah maybe.. Anyone's leak oil bad out of the header pipe?

It happens. Perhaps pipe is tweaked or seal/o rings and springs need replaced.

Ok thanks.. I talked to someone about it and they said its because it's a bigger cylinder.

What mixture you running?

Well I always ran 32:1 but I bought this bike and it seems to be running real rich. What ratio do you run?

Ratio is fine, If it's rich you need to jet it differently

Ok thanks I appreciate all the help

ref leaking oil out of header pipe:  My sons CR85 leaks an ugly black sludge out of his header pipe .  could it be lack of O-rings because today some one recommended rebuilding the top end  not sure why its spewing the sludge, but I would like to get it resolved
