Sludge in exhaust

[rockshoxbiker]

This seems to be a bit excessive for carbon and oil going into the exhaust, right?

What would you think is the problem here? Crappy oil, too rich?

I got this thing a week ago.

Thanks

looks like thats the stock motor which is purposly made that way. they cast the cylinder like that with the exhaust so restrictive to slow you down to 30. now if its a 70 then thats plenty rich.
