250`s ran good, 350`s not as well. When the rebuild was done, was the mid pipe repacked or at least burned out? I assume new main bearings with the rebuild.

Just looking at the condition of the bike, the condenser will need to be replaced or added at the coil wire.

Bend your knee`s you are not that tall.

There is nothing wrong with a Rev 3 for a first bike. But that is way too much money for a 20 year old bike. Tires and all the rubber and air filter will be needing to be replaced. A lot of parts are unobtainable now. It was a pretty blue color vs some of Beta`s choices through the years. 3 grand or buy a newer bike.

If you do end up putting both seals in, be sure to go to the TRS USA website as Jim has a few very good video`s. There is a certain trick to the kickstarter to get the case off easily.

Restored or rebuilt?

Being it is the first since the case replacement, I would hit the dealer up for just the outside seal and see how long it lasts. Pay close attention to the old seal for small plastic pieces. We have not had an issue since last September, I changed shaft, seals and impellor. All under warranty and everything was shipped fast. The engine is really put together very well I would buy another.

I would just change it again. Almost all the time it comes out the weep hole when the seals are bad. Not a bad idea to keep a spare outside seal. Which can be changed without taking the bike further apart. By the way the above diagram is incorrect. You need to look at the 2018 RR parts book. The seals are on the outside of the gear.

Most of the 2018`s had the front seal go. When my son`s went it was because the impeller had tightened up on the shaft and plastic debris had gotten into the seal.

Maybe follow these old threads.

I cannot get a close enough view. Are you sure there is not a centering mark on both the cam and lever. Seems thier was on my 200.

It is low but should run. I am betting you need main bearings and seals.

It has made for an interesting thread Dan. Thanks!

Yeah, you were closer with the Beta clutch fix.(You got 166 thousand views!) Which still is not the problem. It is clutch drag that can be fixed with the proper shims. Cheap, under ten dollars and less than 20 minutes work. You have less than a dozen guys interested in the NEW FIX.

You dont check it, you change it. If it is not leaking you are good to go.

Fastest time should have no place for starting order in trials. Either make it random or the top riders start first. If this was a race I might agree. It was a novelty to watch in person, but has nothing to do with who is the best trials rider.

48 seems what I used. Lots of useless nonsense here. Best kids bike ever. https://advrider.com/f/threads/the-compleat-yamaha-ty80-thread.574301/

Those poor minders, running to spot on 3-4 obstacles per section. And all the comments about riders stopping, you forget they are giving time for the minders to get ready!

You did at that, but a running bike put away for 1.5 years should not have nothing to do with the CDI. It should be a grounding or connection issue. But we all know stranger things have happened.

The main seals could be gone. leave the fuel off and just try fuel through the plug to see if will go. Then a leak down test.

You more likely have a corrosion problem, from sitting than anything else. So, yes trim the wire. Check the bolts. Does the stator have a ground wire? Not usually, it runs through the engine to the frame. Chances are all those bolts are chalk white on the threads.

Didi you actually remove the stator. All the mounting bolts could have corrodid. Always good to remove and clean/lube any bolt that is a grounding source. Also trim back the spark plug lead to fresh wire

There were several brands that worked back in the day. Chances of finding one is very slim. Skyway, seen some modified super traps.

I would still try another carb. If my '16 Factory did that, it would kill me with our steep mountains of solid rock. Good Luck.
