As I cannot see what you are doing I may be wrong but as you describe the problem being that fluid will not push or pull through the system it would seem that the piston in the master cylinder is not against the clip that retains it in the bore and as such is blocking the fluids return to the reservoir. Regards Alan.

Hello you can test the thermo sensor in a pan of boiled water and use a multimeter set to continuity on the terminals. As regards the clutch if you are on a budget you could just use the bike and see how it goes, and slip the clutch a lot to encourage them to comply but personally I would bin them and fit new plates. Regards Alan.

In the UK cheap second hand ICE bikes are not selling , the prices are dropping by hundreds and still no sale , Adam Raga dumped by TRS , a Mechatecno on Ebay dropped from 9,000.00 to 5,500.00 and still no sale after months. Sherco makes a budget ICE model for the market. Personally I do not see any room for any type of trials bike in the market certainly not something that costs 10,000 just to faff about on a Sunday afternoon.

On early models they used to put them under the seat/airbox on the left hand side /gear change side but later models it went where yours is now as its better placed. the tube is the thing that will melt between the reservoir and the rear master cylinder and needs a long spring over it for heat /crush protection. if you need a new piece of tubing it is made of EPDM plastic to survive DOT4 brake fluid 6mm/8mm internal diameter. Regards Alan.

Hello cut a bit off the allen key to get in there better and work it slowly then swap it for a normal bolt with two or three washers when you put it back on ...... or use a flexi extension to get on the allen bolt.

Your picture shows that the reservoir is fitted where it should be fitted.

@Seabag Yep that is as far as it will go on .

@Seabag The kick pedal slides on the splines and then a allen bolt goes through a tophat washer and is screwed into the hole in the center of the shaft thus holding the pedal on the shaft , its best to use medium thread lock on the bolt or it can sometimes loosen off if it has been overtightened in the past. Check the parts book exploded view drawings to see how things are put together. Best wishes Alan.
