@Chaz9462 I personally never had any problem removing the gear off the crank and I have done it many times , normally after removing the clip it just pulls off by hand , it looks like some one has been beating on that one which will probably have made it harder to remove as the edges will have spread , I would heat only the gear with gas/oxy or a heat gun then put a standard gear puller on it after putting something suitable in the hole in the crank. for the puller to push against. DO NOT USE THE CASING AS A LEVERAGE POINT ESPECIALLY NOT ON A MAGNESIUM CASE . IF YOU WARM WITH A GAS TORCH DO NOT LET THE FLAME NEAR THE MAGNESIUM FOR OBVIOUS REASONS .

if you know how to jet why are you asking what clip position . How are your brakes did the slots cut into the pads make your brakes not work properly.

@PapaLazarou Hi its Dave , I have a block in my toilet.

Sorry I did not understand that . Please forgive me. Best wishes Alan.

How to go about doing things is all available on the internet , do your research first before attempting any jobs that you know nothing about , it is so much easier and there will be less chance of damage occurring.

It would be great if jetting were that simple as in reality there are many variables that need to be considered , this is why some people rave on about Efi but that has its own problems at times. To start with have you lifted the needle by lowering the clip into the slot down from where it was when you found it lean and tested that.

Its great when people go to all that effort and also explain succinctly. It sounds like you have no direct experience of the PRO version, to my mind they are a nice bike to ride but the gear box is a bit clunky after 3rd although with standard gearing through the sprockets being tall/high then if you ride UK closed circuit club trials 1, 2 and 3 cover most situations so it has not been much of a concern in my experience. The old contact models motor in the 1990's had a better feel to ride IMO even if they are quite a lot heavier although it did not stop people doing the trick riding the same as is done with the PRO version. No doubt you are probably right about the FACTOR-e box it would make sense not only as a weight saving design but to make a more compact casing also. Any way glad you found it as interesting as I did , all thanks to gravityisnotmyfriend YouTube. Best wishes Alan.

@cedec96 First do this https://youtu.be/G55FU27Z9bU?feature=shared If that does not improve the shifting gear problem then you have to split the gearbox and check the bearings for wear that support the gear shafts then check the (in english) dogs (teeth)on the gear disc/wheel selector sliders and also the teeth of the actual gears themselves and the 'U' shaped selector forks need to be straight also. You need to check the selector drum slots for damage /wear and the 2x small bearings on selector shaft. If you split the engine it makes sense to just change all the bearings in there any way while it is in parts it is not much money to pay . Good luck . Best wishes Alan.

Buy a clutch and brake master cylinder made by BRAKTEC or AJP and a pair of APICO cold forged levers. Outrageous that die-cast levers are even fitted as standard on a new trials motorcycle.

What year is your BETA EVO.

@garydwall Obviously the thermostat switch that is best to use is the one it was fitted with when it was new by the factory who designed and made it. Parts books are easy to find on the internet.

@garydwall the inline one is the early version of the pro and the one located at the top of the radiator is the middle/ 2nd version of the series either will work but a 09 pro had the thermostat fitted in the radiator at the top right corner where the coolant enters the rad from the cylinder head but either will work. Later versions have the thermostat located at the bottom of the rad on the left hand side.

@Chillout1983 Of course you could just skip all that advice as the 4RT does look like a very capable bike. 'Remember this is your life and its ending 1 minute at a time'. Have fun. https://youtu.be/2ki4VgsRG8M?feature=shared.
