This is my Sierra propshaft. I just removed the "doughnut" and i came with this triangle flange. Could someone suggest how i am going to connect this 3-bolt flange with the 4-bolt sprocket adaptor fitted to the motorcycle engine?
If the doughnut is a Guibo you might want to look at this topic.

If you can mount the Guibo between the engine and the center drive shaft bearing, at the bearing end of a two drive shaft setup at an angle of less than 2° you're all set.
This would take the place of the rubber shock absorber that is usually used at the rear sprocket of a motorcycle (a form of a a Guibo).
