Trasmission/Cluth questions

[chidlebaugh]

You mentioned that you've changed your crankcase oil. How about your bezel gear oil? The transmission uses 90wt gear oil in a separate case from the crankcase oil. The fill plug for the transmission is on the left side of your bike. Its the 19mm bolt next to "Use Hypoid Gear Oil SAE 90". See below:


Fill it up until it touches the little tough at the bottom of the fill hole. Maybe you can see it here:

Unfortunately, the drain plug is under the case cover on that side directly below the fill plug. You probably need an impact driver to get those phillips head bolts out, unless they've already been replaced with hex head bolts.

If you've got no gear oil or very old oil in your gear box it could lead to shifting difficulties.

Thanks BassCliff,

I will definitely check the gear oil. Actually I will probably change it just to be on the safe side, not really knowing the history of this bike.

Side Bar Question:
Since I got the bike about 2-3 months ago, I have
(1) changed oil and filter
(2) flushed brake fluid
(3) replaced spark plugs
(4) cleaned air filter

Anything else I should do, besides the gear oil as recommended above? The valves look like they were done recently since the valve gasket looks relatively new.

Mr. chidlebraugh,

While you're at it, go ahead and change the rear differential oil. It uses the same 90wt gear oil as the trans. And seal up the airbox (unless you have pods) with new weatherstripping around both side covers and on the top of the air filter cage. These bikes really don't like air leaks anywhere in the intake system. That includes the carburetor boots (on both sides) and intake O-rings. It's also S.O.P. to go completely through the wiring harness, clean all the connectors and the grounds in the electrical system. Take the ground from your regulator/rectifier and connect it directly to the negative terminal of your battery. Hmmm, what am I forgetting? Forgive me if these tasks have been mentioned before.

Thank you for your indulgence,

BassCliff
