Bushman mentioned it was a 27x1mm reverse thread above?

I know I have an RS puller that was "trimmed down" and I used that on my NSR's. Didn't have the thread pattern/size so didn't want to say 100% yep...

have you looked at asking Craig for the cost of a "specific" tool number?
Rotor Puller: 07HMC-KV30100
Fly Wheel Attachment: 07733-0010000 (goes inside to not damage crank end)
