In love with two-wheeled machines
26K on a 2012, final drive weeping getting worse, now leaves a few drips after a ride. QUANDARY: Dealer can get me in next week, but needs 7-10 days for parts. My buds just invited me on a 5-day tour [Portland to NORCAL], leaving in 2 weeks. The dealer, in Beaverton, says Yamaha can rush the part for extra $$ but on their schedule (not FEDEX, UPS, etc.), and makes no promises on getting the bike back to me on time.
I don't want to miss the trip and am tempted to just clean it up, torque the assembly bolts and go. I'd bring fluid, check an refill as needed. The weep only leaves residue on the shaft side, not brake rotor side of the rim... so far. It's leaked a little for 3-5,000 miles, and was only this bad after the last ride of the season last fall: a one-day, 500 mile tour of Mt. Hood, Adams, St. Helens, and Rainier. I'm guessing the 90 minute, 80mph freeway run home had something to do with the extra fluid leaking... as it was slight before that day, and it's been slight for 3 short rides after that (the only riding I've done since the pics were taken last October).
Go or no go? Any of you push the luck on your final drive leaks? If I go, what are the odds that the seal might fail miserably and me needing a tow out of remote NORCAL? I'm willing to find out, unless y'all chime in and say it's too foolhardy. ::005::
I've never pulled a rear wheel. Looks like a 27mm wrench on the nut on the left, 19mm allen wrench on the axel, 8mm on the swing arm pinch-bolt and the wheels is off? There are 8-10 button-head bolts, holding the pumpkin assembly together I could tighten to improve my odds. They've never been checked, a far as I know (unless some kindhearted tire installer did it). Seems, if I'm going to risk it - I should check those bolts and see if I might get a 1/4 turn outta a few of them. It might be enough to slow/stop the leak.
