hi you all:waving:



gl1000 1997 , i have reset timing 3 times , but is it possable to get the timing the wrong way round ,had the carbs cleaned and reset, valves set ect, and even to make sure the coils work turned the 2 wires from the points around switched the spark leadsfrom 1 and 2 cylinders too 3 and 4 cylinders to check the coils but nothing will change the situation ,that the engine will tick over on 1 and 2 ,i get the feeling that the engine is firing on 3 and 4 because it is so smooth butmust bevery week
the bike when on the road has great power .the spark plugs on 2 3 and 4 are light grey/brown no1 a little darker . the slow air screw on 1 when turned does make the engine revs Alter but 2 3 and 4 do nothing.



thanks guys , mike

Have you actually looked at the spark? (remove plugs.. put on plug wired, keep plugs grounded and look for spark)... thenif you have spark and thenthink it is running "weak" on 3,4 it could be carb issues, partcularly syncronization near idle but other fuel delivery issues if it is at higher speedsunder load..

You don't seem very sure there is a problem Mike. When you pull the plug caps off each plug, does the engine rpm drop?

If you feel that the bike has great power , what do you base your feeling that it has a miss.?
Try a test run and then check each exhaust header for equal heat . If one is cooler than the others , replace spark plugs and check again.
