Default Checking/changing Transmission Oil?

I took my scoot out yesterday and it sounded louder than usual in the transmission. I rode for a while, then came back home and had my OL balance the bike while I pulled off the clutch inspection cover - I couldn't really see a "pool of oil" at the base of the plate.

Is this sometimes the case? Normally I wouldn't think much of it but I worry since the cable boss seems to be greasy at the connection to the transmission... Not dripping oil, but greasy, almost like wheel bearing grease.

At this point I'm ready to call up a friend with a motorcycle lift, and change the transmission oil myself just for peace of mind. It was done last October at the stealership (which is why I'm worried) along with my oil. Oil levels seem to be OK but I plan on swapping it out with synthetic AMS Oil.

I believe you're supposed to check it while its on the side stand. Replace it with exactly one quart. I run Harleys Formula+. Mostly because I can walk in pick it up and I don't have to worry compatibility with the clutch plates.

Interesting you mentioned the side stand and 1 quart. I changed the transmission oil on my 92 Sportster at the weekend and the Harley manual says bike upright (not just on the side stand) and 40oz. So that's 1.25 quarts.

I've just posted a message on the UK forum as the oil change kit that I got only had 1 quart in it and it wasn't enough to fill it to the oil level hole.

TangoDown - you don't need a lift to change the transmission oil. It's a simple job that's done with the bike on the floor. It really is a 15 minute job.

First, let us know what year the bike is. If it's an 04 or newer, the bike needs to be upright (not on the side stand). It will require 32oz. of sports-trans fluid. When you drain the old oil, check for metallic particles. They can indicate internal problems.

My apologies, Billy and Wraith are correct, I let my manual fool me where it says on the sidestand for draining, it later says upright for filling and checking the level.
