Comp. #s"compression and valve clearance is good is good"
We hear that a lot that the compression is good, but once we hear the actual numbers it usually turns out the compression wasn't so good, what are the actual numbers on the 4 cylinders? The difference in pulsing suggests the carb are not balanced, but you can't vacuum balance the carbs if the compression values are not reasonable similar values. I take it you did not personally perform the modifications listed.
"hand lightly in front of the carbs bell mouth(air filters removed" <- Air Filters or Stacks removed, if you're running paper or felt pods directly on the carb mouth with no intake stacks, that would be a poor choice on a track bike.
Picture is worth a thousand words
& ... does the bike have a fuel pump? or does it rely on gravity feed and is it just running out of fuel the further you go from the fuel tap?
1=210
2=200
3=200
4=205
Like I said comp. And tappet clearance are good.
The carbs are RS34's, so gravity feed with a pump internal manual accelerator pump. I use K&N filters.
It's not running out of fuel.
Aside from machine work and welding I have done all of the work myself.
