When accelerating the bike cold there is a knock coming from the(lower) engine. Once the engine is warm the knock goes away. Used good MC oil the one time I have changed it :?: Any one else having this kind of problem???

Sounds like you may have forgotten to use the choke till the engine warms up.

The bike is lean... turn the A/F screw out a little or if you like it the way it currently runs, warm the bike up more -- Check your plugs.. if they are snow white around the porcelain, turn the A/F screw out a little anyway...
