i have a 83 gs850gl. i bought it non running condition. i rebuilt the carbs . pput in new intake boots and o rings. the bike wouldn't start after all that.it would try but not be able to. i took #3 spark plug out to check for spark and the bike fired up. and if i take 2 and 3 out. it ran i checked for spark and all four plugs have good spark.i tested the compression ,i know your suppost to check it warm. but i just wanted to see if the valves where working ok. 1 and 4 have 115pounds. number 3 had nothing at all. and 2 have 15 pounds.i shined a light into 2 and 3 . both pistons and valves are working. so where do i go from here. how do you check valve timing? and is that the next step.
