these coils are available very cheap aftermarket. do not get an aftermarket coil. the aftermarkets have a high failure rate. pay the extra money and get a good oem coil.

@mrcleanr6 THANK YOU! it turned out to be a bad ignition coil. Easy fix. Cant believe the Yamaha dealer couldn't figure this out.
I'm now running at 10k rpm on each engine :)
