@faussy one for you ? (more resistant to movement in high gears)

Fuel starvation ? What carb is it, air screw Dellorto ? When your cleaning the carb are you removing the air/petrol screw and forcing carb cleaner through from every direction ?

"If my pilot is a 33.....And I say if....then 50 does sound high, but if it works for you.?" Depends what elevation they are at.

Hopefully it was just flooded, was the petrol left on ? If it happens again I'd get it rewound.

Always try another plug. Is the plug wet or dry ?

Beauty of rockshocks is spare parts if you damage them, easily serviceable, variety of spring rates if swapping to another bike and you can change the length if required.

I'd guess the spindle was damaged along with the nut, and was shortened.

Try another plug first.

12 years ago the Bosch system was still working as intended (generally) quite a few seemed to have deteriorated over the last few years. What's on yours Glen ?

I'd check tyre clearance and go from there.

These posts are 12 years old so the site may not exist anymore. There is a lot of information in the swm section on here, anything specific your looking for ?

You might be able to buy a length of chain of the correct dimensions and make one. Chains like Regina can be made endless as the pins press in/ out.

In my experience (240 & 280 Rotax) there is always condensation in the ignition case. Well worth keeping the breather and routing it up under the tank, but with a low point to stop any condensate flowing back.

Have you tried a silicon spray on the sliders ?

Do you adjust your pressures when you come out a cold stream ?

Loosen front wheel, fork brace and yokes. Compress the forks several time and re-tighten.

@jbrandt, I'd replace the fender mounting bolts with cable ties if possible.

Quote breagh "This isn't the way it seems to be going with more routes and classes plus a classic scene which to me is just an excuse for running an easy trial." Looks like you've finally worked it out .

A signmaker can reproduce a good image without knowing font. Having something to scale the sizes is necessary, and knowing the RAL number.

Just something to consider, on fitting electronic ignition on a Rotax in place of original points set up, the petrol screw (Dellorto carb) went from about 1.5 out to about 0.5 out before it ran nicely off the bottom.

Have you read all the suggestions and ruled them out, one by one ?

Think its dirt as its hiding the ring.

All of the above, check if your gearbox oil is down pointing to crank seal failure.

New one to me, so the diameter of the axle must be smaller than the bearing if the spacer locates 1mm into it ?

Any hub I've ever changed bearings requires taping the bearing out from the opposite side, having first delicately leavered the central spacer to one side to give access.
