    What might cause a low-speed front end wobble when coasting?

    For sure. Looks like a bit of work to access the bearings: remove both calipers and pull the front wheel, pull the forks from the clamps, and pull the entire handlebar assembly just to isolate and access the head bearings. The actual adjustment & repack looks like less work!

    What might cause a low-speed front end wobble when coasting?

    Front tire looked good. I’m looking for some good how to vids/pics on the head bearing adjustment.

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    OP Follow-up statement: #4 seal replacement was a complete success. One thousand mile SO Oregon/NORCAL tour and no leaks. Excellent.

    What might cause a low-speed front end wobble when coasting?

    I've recently returned from a thousand mile tour of SO Oregon/NORCAL and discovered a new quirk in my bike. Anytime I'd coast down from 35-50mph -hands-off the bars- the bike's front end would wobble back & forth slightly while decelerating. Accelerating it goes away. Hold the bars, it's...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    Nah. Do they wear out this early? A few started to fall out - because I didn’t have support under the tire. My wiggling & wrangling caused a few more to become wedged, preventing the removal of the wheel. I found the whole concept simply amusing and took a picture for those who’ve never seen...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    Well, I got 'er done, boys. I had all afternoon to fiddle with it and managed to successfully implant a new main oil seal in that pesky, leaky, final drive. Thanks of all the tips! Say, I took a bunch of step-by-step pictures and thought I'd make a nice pictorial for those who may be need it...

    I’d rather tackle, “diagonal sticks and gooey shit,” than that job! (Even with the confident pictorial! Thx!)

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    O-ring recalls? Wouldn’t the dealer, the one I purchased the bike from, the one who’s done any service I have ever needed, tell me? I got the memo on the headlight harness (from here, maybe?). I suppose it’s possible that my leak is minor and sone of the FD oil is overflow. I squeezed as much...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    The #4 seal? This part # from Babbitsonline? ( 93102-32480-00 ) It's buried its the pumpkin. I read it's harder to access... looks like you have to not only disassemble the pumpkin, but pull the Shaft Dive Assembly apart to access it. I might want to leave that for more experienced hands. I...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    I ordered 2 oil seals and an o-ring from Babbits. ETA 7-10 days. With any luck, I'll have that wheel pulled and the leak diagnosed by next weekend. Thanks for all the instruction, advice, and opinions mates!

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    I think the green-ish lube in the pics may have been from the weap hole, Don. But I'd only seen that happen last Fall, after the last big ride of the season. Several rides since (short) and I can't see any leaking from the hole. But, the bottom of the pumpkin is consistently covered in a thin...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    Great synopsis! Thanks! I’ll certainly try and acquire a seal, and some seal saver, and see if I can improve things. Thx for the explanation!

    I experienced the same, a year or two ago. It’s the same seal, only older and more leaky now.

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    My sentiments exactly. From what I’ve gathered, Mark, I outta order a seal, clean, inspect, drain, measure, refill and test the bike. Install the new one as needed.

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    26k seems premature for a failure to me, especially considering I ride little off road and mostly fair weather. Also, I’ve never pressure washed it. It leaked some before, than all but stopped. I had this discussion (albeit with much less concern) and figured it normal to see occasional...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    Sounds like I outta order the seal in the morning! Is there only one seal? I recall seeing a variety of seals & o-rings in the exploded view. One helpful commenter gave a part number: seal #93102-70004-00. Is this the one you’re thinking of?

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    I looked inside the "diff" to and could still see fluid. I spun the wheel a little and some came out. So, it's not very low. I've changed it 2-3x in 26K. I thought I'd change it again, measure the drain, and see what I've lost to put it in perspective. The wheel removal looks manageable...

    First Shaft Drive, Seal Failing - Can I ride it 1,500 miles?

    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...

    Riding at Night vision issues?

    51 here. Same. It's normal. Avoid it when you can. Anti-glare glasses help - as do prescription ;)

    The Safety Weave To Be Seen

    I weave from a distance when I sense the left turner may jump. However, the PIAA LED fog lights -that I run constantly- provide the most conspicuity, I believe. Their bright white light contrasts with the yellow-ish light of the stock bulbs and their wide-beam are more visible by drivers...
