i have noise on my 97 techno the noise seems 2 go quite when clutch is pressed. just recently rebuilt engine and gearbox with new bearings and conrod kit + new piston and cyl replate. the noise is on clutch side? as any one else had this problem?

loads of help then?

Did the bike make the noise before the rebuild ? if yes its probably normal (most trials bikes do this to some extent)

If it only did it post rebuild, take it back.

Health warning ! - I have never owned, ridden or seen a techno so if you are lucky somebody who knows might post, if not, ride it and see if anything falls off or take it to your dealer.

As an aside my Sherco sounds like a bag of old spanners till I pull the clutch in

Yep the noise was there before engine rebuild and its not got any louder does not efect it at all just sounds noiser than others?

I'm not familiar with the Techno, but from the symptoms it sounds like the clutch thrust bearing is worn {If it has one?}

If not it could be:

Clutch shaft bearing {you will feel play in the clutch shaft}

Clutch basket worn {look for teeth marks where the clutch plate tabs locate in the basket, also check for play in clutch assy.}

As long as you have no bad vibration I woulnt worry, it is a common sound on older japanese road bikes {in these it is usually a worn thrust washer}

Ive got the 95 techno...and it also makes a noise,

beta say its normal, but if its loud....clean the

clutch plates and it wont be as loud....hope this helps!

your probably on about the 'turbine' sound from the clucth all betas have it

I have noticed that the noise is hardly there when engine is cold and gets louder the warmer the engine is?

Right ive decided to change my gearbox oil tomorrow so i might as well remove clutch cover and check all clutch mecanism and plates. whats the best way to clean cutch plates?

Ive just removed and checked all clutch plates and mecanism and bearing cant feel any play or carnt see anything worn even gearbox bearings feel ok which they should be as there are new?
