Hello - Anyone around experienced with the details of oil pump differences? Understand there is a former resident expert, but for what ever reason I can't get a hold of him.
Questions:
Other than the color coding, what are the differences between early '70's CT pumps?  Is a "364" pulley wheel same for all models...or just torque induction motors?  I now have a 364 pulley but also a 168, R1, 49301, that are kinda matching, to not even close.  They don't show up in the 1973 service bulleten #394 and curious what they are for. 

Reason for all this is related to my previous "oil pump banjo" posting from a few wks ago.....the bike I bought had the wrong pump on it and I'm now planning to reconfigure it,and it seems like the wheel is the most significant difference.
Thanks for any comments,
Joe M
CT1B

A CT1-B should have a Yellow dot pump with double banjo fittings. I prefer the gasket type ( 4 ) over the copper. The flow ratings on that pump I might have on something that came from Dickie Tower’s. You need to bleed it, and set the cable adjustment.

If it was an extreme duty bike I might consider going to a DT1 Black pump but would not run pre mix in the tank like I would the Yellow…
