They were good bikes for the most part, very crappy rear brakes.

So you rebuilt the caliper. Did you rebuild the master cylinder too?

You can guess all day. Take them apart!

In my world I would burn it out. But I have few neighbors close by. Trouble is the exhaust gets packed up real easy, and sometimes those little bikes have a thousand hours on them.

Even when running well a TY8o will go through plugs. Another thing you might do is clean out the exhaust. But always carry a few plugs. It does not hurt to run the engine hard a few times each day!

All vintage guys are all right. AHRMA has a 1 line, but far from expert.

The 80 will actually work with all those oils, and 80;1 will be fine. Ps, just do not run the ty80 at that!

Beta has almost always made there own motors. The `98 had fat bars stock and the rear fender was narrower. You could always post a picture.

It is real easy for the kick start shaft to move out a mm or two. Sometimes it is very frustrating to re- fit.

The weight increases were there all along. For now it will only be directed at the factory bikes. Bring them `works` bikes more in line on what they sell. How far they`ll go in the question?

Myself,I would fix the hydraulic problem before I would replace the clutch.

I think he meant the kill switch on the handlebars and the mapping switch below.

We just finished our second season. We had 17 events in four states. A great format, hope we keep it going for years!http://mtwestvintagetrials.org/?doing_wp_cron=1384825107.4297380447387695312500

The clutch between the 80 and 125(if it is a pro} work differently. A new clutch in a ten+ plus year old bike is not a bad thing, but it might require more than that.

Sorry, page 60. My edit does not work. No wonder the cases appear damaged, clutch cover and center case.

There are many mounts out there. This one has to be a one off custom with all the details it has!

I have had many vans, motor homes, and truck campers through the years. A well kitted van means you are hauling the bikes in a trailer, which I despise pulling a trailer. Been riding and camping more than 40 years. I prefer the keep it simple approach. Two bikes, sleeping bags, one large cooler, small table, coleman stove and an easy up. I carry one 5 gallon water bottle (For bathing and drinking) Bag each for riding gear and clothes. One small tool box, and bike fuel. I prefer a well insulated van. (So buy a conversion van and gut out the bed and chairs) I haul both bikes inside. To sleep I unload the bikes and just roll the bags on the floor. Two people have plenty of room, even better for one as you can leave the bike inside. If you need more electricity than 12 volts, buy a motorhome. I camp more than 30 days every year this way.

I`ve always used 6-7 no matter the brand.

No, the small bearing looks like it could be from the blind bearing on the end of the kickstart shaft. You might post a picture of the other parts to see what`s missing.

So the real story. Did you knock the kick start shaft out and shove it back in for the picture?

Clean the carb, clean the petcock and change the oil. Fuel at 50:1 and give her a test ride!

Just buy a cheap 520 chain of the same length (as what came with the bike) if the rear sprocket is not obviously worn badly.

You do not need any changes to go to 10t.
