Beta clutch drag can be easily fixed by shimming the clutch push rods excessive free play. This video has been around forever.

Is your shifter hitting something.

The St300 akways had a problem cheaper to move on.

I have to laugh as the first time I saw one I declined the work. The rod was good, but the guy insisted on a new rod.?

So it is the price of a rod verses the crank price. If it was mine it would be done already.

Not everyone has a competitive spirit and not everyone has a fun club to enjoy the sport with. It is amazing how many people buy trials bikes and do not compete. The biggest thrill of a trials bike is you can go about anywhere (hopefully legal areas.) It is far easier to ride hard trail on a trials bike, no matter your skill level. I had always hoped at some point I had enough time to mix my riding skills with remote camping, fishing, exploring, etc. Do what makes you have the most fun. Lucky for us we have a trials club that enjoys camping as much as riding/competing.

At that point, 3 in three years means you have some other issue.

Have you replaced the shaft? The seal should last many years.

Well if you are looking at it, you should be able to tell if you are tooled up enough to do it. The last time I looked at one I passed as I did not want to screw with someone elses crank. If it was mine, I might of tried. I have done a few dozen over the years, but all solid cranks.

Being my Japanese is non existant, I am hoping for better clutch action. As eliminating clutch drag and a better hitting clutch. I have known about the shim trick for years , but could never find them thin enough till recently.

The newer bikes have plastic inserts instead of a full crank. Which makes it difficult with out the right set up.

I am going back to the guys that seem to know what they are doing. My shims should be in Tuesday, http://wise-motosports.ocnk.net/

What size tire and make? Missing the speedo drive?

You have the floats upside down.

If you just bought this'99 then it is well worth looking at the plates. Most of the original plates, the friction material becones seperated from the steel. New plates may be needed.

So you pulled the jets and made sure both passage ways on the pilot circuit were clear? Rust in the tank?

It means it is plugged up. Clean the carb.

The gasser feeds the mains with transmission oil. Not two stroke oil. Nothing like a Beta.

The rebound side sucks up when properly bled. It evens out after awhile.

Sounds like it is running fine considering you are burning tranny oil and losing crank pressure. Time to split the cases.

Needle and seat. Float height plus float flutter. There is a tab on the float that stops it's travel. This can be adjusted to stop the float from too much movement. Also this can be a venting issue.

Keihin?

My son actually has a 42T coming today. We are trying it for a whole other reason. To bring 2nd gear down just a touch for splatters.

We all know normal is not normal 1800 rpm tick over on the 4RT.
