I was thinking it might be good for the boss once he sells his boat Whadda ya think Don?

Nobody ? I need some help here! I have never been this deep in a motor before. Also, could someone please explain the process for removing the valve guides and seals? the manual and video don't explain the how...they just say to do it. In the manual under the special tools, it's hard to figure out The diagram of the valve guide remover on how to use it the re installer just looks like a spacer.

Most stuff is interchangeable. Engine,transmission ,rad, starter, yes clutch is different body panels yes brake calipers, forks, anti dive and I think TCI no

A good buffing and it will be as good as new! maybe not. Such a shame! Should be able to tell better after a good cleaning.

Check this out. looks like it's out of the 60's??? https://www.facebook.com/MotorcyclepediaMuseum/videos/1053884151341859/

I made up a valve spring compressor by cutting up a socket and using a C-clamp But now I still have to remove the valve seals to get the valves out. The manual calls for a special tool but is this really needed or is there something else that works. If I have to buy a special tool is it specific to Yamaha or can I buy one elsewhere?

I'm pretty sure the answer is No, the 83 is unique from all other years

Why not just plug in a known good tic and see if it makes any difference

be REAL careful when you do the shims. If the tools slips or if you feel any resistance STOP!!!! I used a tool that had been broken and re-welded and I think it had bent so the opening was a bit wide and it didn't fit the cams properly. In my ignorance I used it any way and in so doing I mashed some of the aluminium between the lifters. I've tried grinding but several of the lifters are jammed. So now I had to pull the motor out of my parts bike and I'm going to use the heads off that. A LOT OF WORK!!!! Like I said...tread lightly. They say you learn from your mistakes and Hindsight is 20/20. I should be a genius by now an be able to see a pin head at 200 yards!

not to mention the drinking and driving!!!!!!

So tell me Larry, do you think this marriage thing is going to work? Congrats to you both!

Carl, I'm really sorry to hear about Marca's Mom. Please accept my condolences to both of you and give Marca a big hug for me. Remnd her of the promise at John 5:28,29.

My wife said sell the bike. My first thought was "I can't do that!" But then I reasoned... She had quite a few miles on her and the suspension was starting to sag. She leaked gas, was getting hard to start in the mornings and that whine just drove me crazy sometimes But even so, I still enjoyed the occasional ride. I'm going to miss her. The divorce becomes final next month

Such a tease! It has been said Harley Davidson is a clothing company that sells motorcycles

No....looser but still not free. But now the motor is out it might be easier to grind. There was just no room at the front. I'm butchering the lifters in the process. so far I've been working on just the 2 cyl 3 exhaust lifters I'm going to pull the heads regardless. I'm thinking if I can push the valves up then it might be easier to remove the lifters....giving better access to grind the head as required. As it is now I can't get to all of it.

Replacement lifters are $40 each!! Head gasket about the same. looks like I'll be tearing into the parts bike for lifters anyway...might as well harvest shims too.

you're right again! Is it getting hard to be humble? lol I found this on google... Keys to symbols U.R Use size (thickness) and/or number as required couldn't find anything on "OS"

In the parts list for valve lifters (or shim buckets as they have been called) there are 2 listings see picture...both are part #9 26H21153-00-J0. LIfter, Valve (OS).......16. U.R. 26H21153-00-Y0. Lifter Valve ..............16. U.R. What at does the (OS) mean and what does U.R. mean?

Your old man drugged you up rightly! He must be very proud to have a son like you!

been grinding the head where it was mashed over the buckets. so far no success in releasing the valves and buckets. I can rotate the buckets by tapping them but they are by no means free....the buckets still won't return to normal height. I tried grabbing the shim bucket with a pair of needle nose but I can't get it out no how! I know they should because I tried one that was loose and it lifted out easily. I'm going to have to replace the shim buckets because there is no way to avoid grinding them at the same time. I zip tied the cam chain to the cam gears and removed the exhaust cam so I could work on the shim bucket area. in case I have to remove the heads.. I found the cam chain link but it looks as if both lobes are a grooved split rivet that spreads to hold. Do I just squeeze the split rivet together to remove or do I have to grind it off? I'm thinking probably not but I figured I'd ask to be sure......Are the heads and valves of a 1200 the same size as a 1300? I'm Thinking of my parts bike and just swapping heads

Gotta ask... WHY WOULD YOU WANT TO?
