Low end is fine...
So today this is what i've tried.
Warmed bike up and checked again for air leaks, carb rubbers hoses and vacuum hose using a propane torch, not lit
Re did Blip test, set idle to 1000k for the lean blip part...nowt happening, rev needle behaves normally returning to idle.
Removed airbox and found a small tuck on the right carb on the back this time but not showing a leak during test !
Set pilots out a 1/4 turn and went for a blast.....no change, still erratic between 3.5-4k but again can power through.
Set pilots out another 1/4 turn so were at 21/2 turns out now and went for a blast, still erratic as above, maybe a bit worse, hard to tell.
Blip test out of curiosity, no change from the 1st Blip test.
Stuck me nose on the end of the exhaust, not smelly like to rich.
No leaking thermostat onto right plug, HT leads seem good !
So conclusion...... If i had an air leak would'nt the idle be jumping around which it's not, so i think good.
Float height, seeing how i can power through the problem i suspect the heights are good !
Dont know if needle clip position has been changed previously ! dunno where they should be set, cant see it in the Haynes, will check JBX.
So i think i will have to start from scratch and pull the carbs for a good clean, not done previously bar a blow through of the jets and check needle clip position for starters, am quite pissed off now after going through all this crap with me mk1 carbs and have them set up perfectly only to crack a fookin float bowl..
Am a bit miffed that Mick and Borge have stuck em on without issue...bassads
Suggestions very welcome, i have petrol
Edit.... actually i dont think the carbs would need much of a clean up cos apart from the 3.5-4k band they work fine, if any of the jets were gummed up or dirty i would have problems with fuel delivery from idle...more down below..
