    I have a '73 R75/5 LWB with a 5 speed trans. no kick start. My clutch is shot. How do I find out what year this transmission is, so I can get the correct parts.
    Any feed back would be helpful

    If you can see the front of the casting, where it covers the clutch, it has a date stamp. This should give you an indication.

    Is it a smooth case or does it have the strengthening ribs of the later models?

    Honda Moly 60 works well, I bought the 2 oz tube and it will last ten life times, you don't need very much. PM me your mailing address and I'll send you some.

    Another spline lube grease to add to my collection. I still have a tube of that #10 something stuff, somewhere, and of course Honda's entry.

    I'm game. I can use a couple other things anyway.

    All 70-80 clutch and driveshaft parts are the same. If your clutch is original you will not reuse the pressure plate spacers and I would use the later driveshaft bolts that are short enough not to need washers,

    Use a small amount of any heavy grease. Smooth non kickstart transmissions were 75-77.

    If the top of the case has a series of holes (three I think) drilled rearward to allow water to drain from the airbox, it's probably a '74 or maybe '75. Later smooth-case or at least single-rib transmissions did not have those holes.
