This is covered in Stalling on Downhill in the Sherco forum April 5, 2013

I believe that some of the newest Sherco's with the rear mounted fuel tanks had some extra " plumbing " . I think that the fuel feed line to the carb had a " T " fitting and the third hose went back into the fuel tank. Hopefully someone else remembers better than I do. Good luck.

I believe that the 4 speed Ossa trials bikes were sold as " Plonker " in the USA They had a different name in Europe.

Jan Peters was 2nd at the last German Championship event on the Beta 300 4t

This tube and check valve is connected to the exhaust head on the motor side of the catalytic converter that has come with some bikes. I believe the idea is to add fresh air to the exhaust to help promote cleaner air to come out of the exhaust. The check valve is so that exhaust does not come out of this tube.

You guys are correct yellow and tab mount AC in / white connector to the fan / grey connector to the t-stat switch

Rear brake master cylinder same as BETA

Sometimes the d/o floats do not float, this may be your problem.

Clutch and f/b hoses are the same for Grimeca or Braktec pumps

From the reed valve .

Order the gasket.

There were some Betas that had the ball bearing under the bleed nipple, this set up was stock for some model years.

D/O carb may fit BUT you will have trouble adjusting the idle and the idle mixture. To change to a D/O carb you will need a right hand model. To change airbox you will need to change to the 2 piece rear frame m/y 2002 to 2008 , and also change the r fender to a m / y 2002 to 2006 , as well as the airbox

I think you should use Repsol oil in a " Montesa Repsol " It just makes sense !
