Leaky Mikuni???

[OldTimer]

After a good long ride last weekend I noticed oil on the bed of the trailer when I got home. I retraced the path of the oil leak back to the little pee hole on the carb. between the choke button and the air screw. Seemed like pure oil I guess because the gasoline had evaporated. It's a Mikuni TM38. The bike runs fine but it's an oily mess and well... it's also like having a hole in your piggy bank (ya know?).

Little bump here. I'm still having the same problem.
Oh yeah, I leaks throughout the ride. The motor is covered in oil after each ride.
Any ideas?

Float level maybe? Dirty carb? I had one do that and cleaned the carb REALLY GOOD and it was over after that. That little pee hole your talking about (between the choke and the IDLE screw) is your carb overflow vent. There's an overflow on the other side too. Those should both have vent lines on them. Its been leaking 5 months? If it doesnt stop I'd run those vent lines into a little can and salvage that premix. ;)
