Is this happening while riding or are these observations made with the bike in neutral in the shop? How are you determining that the right cylinder is the one cutting out at 5000 rpm?Ive done everything i can think of to my 82 gl500 and it wont go over 5k rpm. At 5k the right cylinder quits firing.
richhow does the plug look on that cyl
Ive done all that. Problem stays on right cyldo a pulse gen resistance test 530 plus or minus 60 as per the fsm
swap igniters leads around see if the problem moves
swap the coils from side to side
swap the spark plug caps side to side
While riding. If i pull tge right side spark plug cap while riding it continues doing what it's doingIs this happening while riding or are these observations made with the bike in neutral in the shop? How are you determining that the right cylinder is the one cutting out at 5000 rpm?
GLs are TI.
A poor spark causes sooty plugs.. Not just mixture issues.
My bike has tai ignition not cdiI just went through the forum search with this being a very common issue to cdi ignitions as they have a high speed and low speed windings on the stator - the high speed winding could be your issue
I ohmed out the ti system and it was good and it has a new coil. Is there any other way it could be weak spark?GLs are TI.

The right cylinder had low compression then i rebuilt it now it has good compressionhave you checked your coil connection (cleaned them up) also check your ground connections. which cyl had low comporession?
Smells rich at idle too. Tried messing with air fuel screw and still does same stuffAt 5000 rpm and not firing I would expect it to smell rich.
