Overdrive-I did it on doubleg910 bike seen in he gallery. Easy peazy lemon squezy...plenty of comments already so I will just encourage yo to get a shop manual, and the Yamaha OE webssite under product line (MC), then model etc is esentially a microfiche with some neat manouverability w/in the screens. Look for the trans ans see how it goes together, apart, together...really a piece of cake if you can do those other things. Pay attention, you do not have to strip the whole shaft, just the one gear. Be aware that when you encounter a fixed gear, that is one that does not slide during a shift, there are clips that hold it in place. Get the correct snap ring pliers to do that job right then put it in the toolbox for the next time...pay attention to the snap ring, does not seem like much, but one face is flat and the other face has a slight round edge. The round edge faces the gear so as to float a little better against the gear face. The flat edge has in the past gained traction from the face of the gear and the shaft and sprung out of it's groove and on it's merry way. So, mechanics 101- any c lip next to a stationary gear must be put in rounded edge facing the gear it will ride against. The details are sometimes hard or unknown, but the main part is easy. Digin, do not be afraid. You may have to back up and try again, big deal...go slow,folow the book you'll figure it out..(get a clymer or other shop manual, it is worth it in resale value alone....read thru it cover to cover and you will understand your bike better and be able to takle new things without trepidation. You can do it!!!DoubleG

DoubleG did you install just the one gear or both as a set? And what rear sprocket did you end up with 34 tooth or less teeth? Any gear whine to the 5th OD gear when running at speed?

DoubleG- I wrapped the whole mess up a few weeks ago, guess the update was buried in the responses on page 2. I have the manuals etc., but of course with my luck I found the one spot where the diagrams were vague and had a go-round with the shim/washer layout for the clutch assembly. All is well and the bike is chooglin along dandy. My mind tends to make things more complicated for me until I start doing the actual wrenching, then of course it's a pleasant surprise to find it wasn't all that tough to do. I can now growl along at 60 or 70 with a lot less effort. Richard- So far this bike doesn't make any new noises from replacing just the one gear. 32 tooth rear sprocket and it's now a lot less high strung at speed. I guess it's on to new rear shocks and exhaust now ;D

Cool that's great to hear I’ll probably do the same 82 I’ve been working on. I have a 32 on my 71, but there have been times when I could have used the lower gearing. They are doing a lot of road construction up in the hills here so less than 10 mph is kind of hard on the clutch.

Yours stays upright at 10 mph?? Must be the heavy helmet I wear. And I agree, the 32 is nice once it's rolling, but from a standstill it takes a bit of clutch/throttle fuzz to get it going. Glad I took everyone's advice and decided against the 30.

Last time I went to Sequoia I went up the 198. They are always working on that stretch of road, this time is was so rough and single lane it knocked my front wheel weights off and rattled my tach where it stopped working. Going up at 10 mph I had to drag my feet in spots to dodge the rocks. With a car in front, one in back and cliff to the side there was nowhere else to go but up. Once I got through the construction I still rode the rest of the loop through Kings Canyon and down 180 which was about 120 miles. I replaced the tach at home with a spare, rebalanced the wheel and adjusted the clutch. I’m good to go now, couldn’t find any other damage. Trip before that I needed lower gear while cruising campgrounds looking for a place to camp. Stuff happens :-)

The custom, hand-made (with vise, drill and tubing cutter), one-off, XS650 upside-down engine stand mentioned previously. Think I should sell the idea to Mike's?

Rube Goldberg would be proud. Maybe.

I know I'm impressed, this country was built on ingenuity like that. I like that it's inside with a couch and all. It reminds my of the good old days when I built a Sportster on a blanket in my kitchen. Only back them I didn't have a fancy stand like you have. :-)

Wellll....I still don't have a garage built after 15 years here, and I've worked myself into a corner finishing the house off. All the tools, saws etc that should be in the garage have been stuck in one half of the livingroom, which is the last room to finish. I can't do that until there's a garage. Upside is that I can watch dvd's on a big screen while wrenching on whatever fits on the bench. Sadly electronics don't like sawdust too much. A bachelor pad if there ever was one. And the engine stand was made from tired old chunks of used conduit. I literally pulled them out of the odds and ends pile in the shed. I'm not cheap, I'm....uhhh...frugal. Yeah, that's it

I think that's cool, enjoy it while you can. women can't appreciate the utility of watching TV and torquing a cylinder heads at the same time. Next thing you know you'll have a fuzzy toilet seat and the bikes with be out in the garage.

Had a few fuzzy bathroom sets already, but my antique cat likes to use those (and anything else that resembles fuzzy...like carpet) instead of the litterbox. If I had a garage up, that cat would be roughin' it out there instead. I won't tell you how I finally broke her of that habit, as this is a family show, and it has nothing to do with bikes
