I have a 2000 Yamaha GP1200R about 125 hours. I bring and install StageIII.
Front cylinder still very cold, central and rear cylinder is heating. The engine working not stable. I mean no ignition in the front cylinder.
I swap a sparking-plug between front and central cylinder. no result. I try to unplug sparking-cap from any one of cylinder. The engine working same ( of course not stable).
I try to plugin other one sparking-plug to every cap to see spark. a spark is present, but poor in comparison with automotive spark. (poor spark it's normal for the engine or not?)
Fuel is come in to the front cylinder. i can see fuel upon sparking-plug when unscrew it.
What i have to do? Improve spark or try to find other problem?
Help!
PS: During installation of StageIII i replace in rear (not front) cylinder a valve, piston and rings, because Yamaha's guy forgot to add small amount of Loctide at tread, so the valve fall in cylinder. Other cylinders is looking good.
