we have improvement!
cleaned out carbs again and got rid of a good bit more crap. looks like it was drawing air too, new seals fitted.
it revs cleanly to 9k now on the road.
power valves are working so i think i will go for more carb cleaning to see if this is whats is limiting the top end.
could PGM problem limit the top end? i would recon PGM's either work or dont, but thats not based on anything other than being male and thinking i know everything.
thanks for the feedback to date, its got me 9000 revs more than i had
