@oldman Honestly, I am building this RS and I have literally AJSutton exploading parts open wishing they were SVGs, I know this tool will be useful to restorers who want to know how it all fits together.
Been driving me crazy how the seller of the engine said it was from a cb750 but appears to be a cbx750 engine (much older + hydraulic clutch) rc17/17E
But the engine apparently had only done 12k
Also looks very new for something that would be 40 years old nearly.
After a lot of research the Japanese did a later 2007 LTD with the Rc17E engine when looking at the part numbers for the upper crankcase on this models parts diagram it confirms this.
This is a super rare models engine, + hydraulic clutch optional extra. On an import!
But it will work perfectly for me, just ordered the correct pulse generator.
Writing this down for future reference because I'll forget.
