Gas leaking from the over flow tube tells me that your float bowl is either not working correctly or not set correctly.

Do you have the service manual?

Bogging at high rpm might mean the bike is lean?

I would but a carb rebuild kit and replace all the Jets, seals, etc on the carb.

Have not done to much to it yet. Going to reverse bleed the front brake tomorrow, it is super soft. Naturally, going to flush all the brake fluids on the bike too.

The oil was black and the filter was in bad condition as well.

Got the forks rebuilt and installed. Thanks for the help!
