That is 'nornal' on a diaphram clutch! The oring should not go bad if you are using mineral oil. Must be that tractor lube!

You were repying to me, again! LOL The Montesa clutch has never been very good ever. But we all have opinions. You should know better. Don't you ride a TRS now?

There is a reason the hrc machines use a different clutch.

The plate holds the springs straight. They other wise rub on the towers. The springs are much lighter. Available from Webike.

There are springs and plate available which improves the clutch feel. of course it`s only available in Japan.

The top riders use x11's.

The michelin is the best, nothing wrong with the IRC. If you find an 803 buy all they have. the rest of us can`t find them. LOL The TL01 is crap I threw mine in the trash after one event. And Dunlop knows this!!!

https://trialssuperstore.com/collections/engine/products/gasgas-shift-shaft-center-locator-and-spring This is the first part to check. that little thin piece of metal is designed to shear. The spring is included and zipped tied as it`s hard to install the spring. Its possible to weld this back together, just the spring is hard to deal with. Good luck, it`s probably one of these parts have failed. The top hat is the easiest to fix.

The weld broke on the shift shaft. You need to take the clutch off to get the shaft assembly out.

You might slow it down. It's awful fast with the stock gearing. Using a 9 tooth is the fastest choice. I prefer something in the middle. A 42 rear. I like a 9 and 38 actually.

With lean jetting the valves could be slowly fading with the heat. Try a compression test. Also the intake boot is prone to cracking.

There you go, it is not pressed all the on the one side

So I looked at your pictures. Show us how the pin sits in the crank from a side view. Most rods only needed 18 thousands clearance. Granted I have luckily not done a bul.

In case they have not told you, the pressure plate only goes on one way. On the clutch one of the posts will have a notch in the end of it. That aligns with a mark on the pressure plate. Good luck.

???? Is this some Ai crap.
