Resurrecting an old thread.
I notice the CRF230 guys running 120/45 for jetting but that's on a true PWK28. These aftermarket units I can't say.
I went with this one, 30mm, comes with 125/38 for jetting. I'm wondering if the 120/45 is the way to go. Thoughts?
Note this one doesn't have the power jet like yours does.
