Topic: Resolved some problems. Got an extra 20mph.

1973 CB350f, Mac 4-1 exhaust


So I swapped out my main jets today from 75 to 78.  Before doing so the throttle could only be used sparingly and if I coaxed the bike I could get it to 70mph given a long flat road.  After swapping the jets, I took it for a quick spin on the Interstate.  Bike topped out around 90.  Throttle worked amazingly even at WOT.  Acceleration is better, Speed is better.  I enjoy the bike a lot more.  The only thing I still worry about is the #2 cylinder.  The plug looks amazingly lean. The other 3 are fine.  Ideas?

Carb boot air leak on #2? Check for it.

And check your valve clearances too.

This might sound daft, but what does WOT mean??
