Alternate Primarys VT750 C Shadow
Reply Quote

Has anyone ever tried fitting this primary gear and clutch? - its a much better ratio than the GL650 clutch if you are looking to alter ratio's and drop the revs in top gear for cruising speeds, and as such it could be done as a stand alone mod, ie you would not need to change wheel sizes to enhance it etc?

Failing that has anyone got such a clutch and primary gear, I will see if it fits

80-83

As the gear number are close ( GL5 33/74, GL6 36/74, and VT750 38/67) I suspect the centres (clutch and crank) are probably identical, which would mean that apart from a little minor mod it may well fit and then theres just the clutch and case to consider. Well worth a look though

Don't forget the splash shield as it is different in the 650's so I bet it's different in this one too.

Oddly enough, stock splash shield works fine with the CX650 TURBO clutch :)

GL650 is 35/74 If you coild get that gaer assy to work you would propably have to get some one to push you up to about 30 mph just to take off in first gear. That's just too much of a jump.

A gl650 assembly will work fine with no pushing. And Doward probably went to the extremes with the turbo clutch.

Yes, I can definitely say that the bike won't just take off if you dump the clutch - you will stall out (running the CX650 Turbo clutch, which, to my knowledge is the steepest ratio'd primary gear Honda ever put in the CX family)

As long as I utilize that 'Friction Zone' they kept harping on in the MSF, I have no problem taking off, even on hills (or what constitutes a 'hill' here in Florida!)

That said, I do intend to drop my 18" rear wheel down to the 16" wheel + CX650T clutch setup wheel to compare - I think the 18" wheel might be a bit too much for me, pre-Turbocharging.
