Hi All,

I've got the exhaust off my bike (I'm doing a swap) and am thinking that I should change the final drive oil. A couple of questions:

I know the idea is to get the thing warmed up, but obviously I don't want to put my exhausts on, go for a ride, and then take them off again. Nor do I have any need to take off my back wheel.

Can I change the oil cold?

Next question: up here in Canada, I'm finding Synthetic gear oil, 80W90 or 75W90, GL-5 rated, but it doesn't say anything about Hypoid.

Do I need to get a bottle that specifically says Hypoid? Is synthetic good or bad? Does it matter if I'm using 80 or 75?

As with everything on the Net, I get conflicting answers. What does the group think?

Plenty of the old stuff will drizzle out cold. I have a front wheel chock, I hope you don't have
to sit on it holding up straight for half an hour  Wink ...

The appropriate HONDA brand of oil says "hypoid gear oil, Exceeds API service classifications GL-5 and GL-4,
80W-90", any old stuff you can find down at Advance Auto that says things like that on it will be OK.

Synthetic gl5 rated=hypoid.  Cold, just let it drain longer.  Fill on side stand, pour in 150cc, none will leak out but it will be properly filled.

I've found a few bottles of 80w90 GL5 rated that say they are hypoid and good for passenger cars, marine, tractors, but motorcycles are never on the list...

The GL5 rating is all you need to have. No need to see "hypoid" as long as GL5 is there.

Either 80-90 or 75-90 is fine, if the right rating.

If you have one of those little ceramic heaters, you can put it under the drive unit for a while to warm it up. 

Do not confuse the top vent with the drain or fill holes.  The vent is not supposed to be pried off.

Go easy on the plugs, they don't need torqued down
