Right Sanket. I have gone the Paul/BW way with the piston-cyl barrel mod as i was getting the engine rebuilt a few days ago. Now the bike has a higher compression and you can tell by the bump in the KS effort needed.
While i was at it had a few 1.5 mm shims added under the valve spring to increase a little spring tension. The carb was running lean with a 130 main, and even a 140 main. Now i have put a 155 main - let's see.
With the old iron cams, I did out accelerate my friends AVL with the VM34 through the gears with both bike running a 19 tooth sprocket. Only issue is that the cams are pretty noisy and there is a massive increase in the exhaust noise. Now I am unhappy with the free flow
- need a better option now!!!!!
Paul, do the S cams also run noisy on the AVL
