Hi Guys sorry my first post is a cry for help i bought a 96 that in the last 18 years only covered 800 miles so i began to refresh the bike. new radiator, hoses, coolant housing, water pump seals and gaskets, sump gaskets, exhaust gaskets, Carb overhaul kit ,fuel petcock also flushed and cleaned the tank.
during this i damaged no2 carb body as the pilot jet was welded in situ as most of the others where but i got those out ok. so i bought another bank of carbs split them down and cleaned overhauled it and rebuilt my bank (all new jets ,seals, o rings etc). refitted the carbs and and erratic idling - more tweaking and now my no3 cylinder not firing. so done so far
Checked spark on all 4 cylinders - OK
Checked compression on all 4 - OK (all the same 170psi)
checked fuel bowls - all have fuel in them
squirted easy start in all 4 - only no3 dosn't respond to it
carefully covered all inlet trumpets and the sliders respond apart from no 3.
Split no3 carb used carb cleaner again on all holes, blown through with compressed air, checked diaphragm no splits rebuilt and re installed - same issue.
Vac tube on no 3 checked and is ok - no splits
so im at a loss, my next check is to see if the exhaust manifold is leaking massively on that cylinder, visually looks ok.
any help appreciated
regards Ian
