Growler: diagnostic tool used to check rotors for shorts and opens. Much more effective than a meter.
Yes cranks slow, and intermittant no crank just started this season. Field and commutator both meter good, + brush is worn and angled. Ordered one from local dealer, now the big wait. Love living in a small town but hate the parts availability.
Wife has a 1982 XJ750 Maxum, runs great. I still have a 79, 350 Daytona in the crate, Yamaha's last thumb at the EPA.
XJ1100's were great. The XS1100 was a beast, loved them
