Hi all ran the bike up properly today I am still getting smoke out the left pipe starts clear then after about a minute it smokes not to bad on idle 1100 rpm but when i throttle it it gets worse nothing right side I am thinking rings probably. should of checked when I had the engine out but found that a valve stem oil seal was shot and thought that was the problem.
Could it be air leakage from the carbs or floats timing chain seems correct tension is good.
when removing the plugs the electrodes outer and inner are black and shiny but the face around the base of the threaded section of the plug is silver and clean on both sides tells me i am a little lean rather than rich. Not sure what to do but do not want to rush and pull the engine again. I am thinking of changing the mixture screws as they are missing the little "o" rings and washers that sit below the the small spring for new ones from mikes and new carb rubbers engine side.
As I said the timing is in the "f" mark fitted Pamco high powered system new ATU solid state regulater rectifire iridium plugs new head gasket re seated valves that where a good fit in the valve guides no wobble side to side, compression was good 145psi and 140psi. I am wondering if the previous owner who had rebuild the engine popped the oil seal upside down or has not staggered the ring gaps.
read a thread last night where another chap from England took his engine out four times due to the same problem and it was rings .... could it be my piston sleeve on the left is scored DAMIT bike runs really nice can get good low idle speed adjust the carbs mixture does not cut out and rides good too wondering if i just leave it for a while and see if it settles ,,, not sur what to do
