Now I know what you guys are talking about when you say you "miss" second gear. I just finished doing the second gear repair on my 83 and wow, it's a real treat being able to get on the throttle hard in second without having to worry about it popping out even under mild acceleration. All in all the repair went well but I do admit I was a bit baffled when I had the engine ready to come out and just could not figure out which direction it needed to go to get out of the frame. After considerable trial and error, I found that the front of the engine has to come up and then forward to clear the output shaft all while giving it a twist to the right. Likewise, going back in, the procedure in reverse worked great. Once on the bench the cases split apart nicely and the problem was the worn thrust washers. While I had it opened up took advange of all the recommendations on this site and replaced all the o-rings and seals that had been breached and I had the gears undercut to prevent slippage under load. Naturally, I replaced the thrust washers, the washer that goes behind them and shift fork #1. While I was not sure that my shift fork was bent, I replaced it anyway and I noticed that the new one was a beefier design. The parts, including all the gaskets came to about $175.00. I also installed the clutch kit from Skydoc_17 while I had it open, another $70.00 Reassembly was cut and dry with the only tricky part being the application of the Yamabond sealant and getting the shifting forks to line up when mating the cases. Once the engine was back in the frame (remember, go in high) I completed the installation and fired it up. After assuring that there were no leaks and everything was up to operating temperature, I took it for a quick spin and the gears worked perfectly. Thanks to all on this site for their wealth of information, help and support. I've added some photos from the build. 1. New thrust washers installed 2. Shift fork #1 3. Ready for lower case 4. Ready for lower case 5. Worn out thrust washers

I need to know if this is correct. [ATTACH]43583[/ATTACH] [ATTACH]43584[/ATTACH] [ATTACH]43585[/ATTACH] [ATTACH]43586[/ATTACH] [ATTACH]43587[/ATTACH] The thrust washer that is behind the basket that holds all the friction disks , It goes on the splines and then drops onto the flat round part leaving space and wiggles around is this correct ? There are no splines after that and under the clutch basket it self. Just wanted to make sure. Thanks, Jeff

Just in case you all were worried about little olde me, as two members who emailed me today were, Scamper is back to her old normal self with a little more life than usual. This maybe due to the fact that she's been sitting since mid November or due to the fact that she now has been babied and caressed beyound believe. Second gear was fixed, carbs cleaned but not rebuilt, engine cleaned out thoroughly, new oil and filter, tender loving care in many adjustments,,, tightened engine mounts solidly, new plugs (non-risistor type) maybe not a good idea), so far lots of noise,,,, new Avon on the back, new pads all the way around, some new bearings, seals and clutch basket, (I'll not say why), clutch installed according to book instructions, which means that you put the basket in first, then the thrust washer, then the boss, after which is the locking ring and finally the nut. Yea I know, the thrust washer needs to be in the right place, you can't just put it somewhere and hope it goes to where it should be,,,, doctors have it much easier, they can just throw it all back and it will striaghten itself out LOL. So last night about 11:45,, 2 scoots were headed for Burford for a quick test run and soo far everything checks out super. Boy what a good feeling. Thanks all for the help and input and concern,,,,,,,,,,,,,,we're on the road again........................... Carl
