Hi guys, how do I remover the black plastic inlet fitting from a grimeca rear master cylinder? I'm rebuild it and I think there may be a leak from it. Thanks
Hi, sorry more questions. I'm trying to figure out my fuel system on the 2007 rev 4T 250 4-stroke. Mostly out of curiosity so if anyone knows them and could fill me in I'd be very thankful. OK in the manual the fuel tap has a weird looking fuel tap? My doesn't have the same. I'll add some photos. Mine also has a fuel outlet at the back of the tank with a weird nob on it? The fuel outlet on the side of the tank doesn't seem to have an on/off? The fuel lines go into a little chrome cylinder which I'm guessing is a pump? It plugs into the wiring loom. The block connector the feeds it has 2 extra wires that have been cut? It also has a hot start cable that runs into the bottom of the intake manifold but some cut the cable at the headstock? Do I need this? Thanks again everyone for help and advice. Noel
Hi everyone. I'm totally new to trials and just bought an old 2007 rev 4T 250 4-stroke. I'm fixing a few things and have a carb question. What carb is in my bike? I want to order a kit as the bowl gasket it weeping. The carb is a mikuni. There is some writing on one side. Looks like 33 79 L691? I did ask chatgp and it reckons it's a mikuni BSR33? But just want to make sure. Thanks Noel
Hi everyone, I know this seems like a stupid question but I just bought a 2007 beta 250 4-stroke and I'm trying to find out what exact model it's is? VIN is ZD3T3020070000206 . From what i can find its a rev 4T, but then I'm seeing evo's and 4RT's and rev3 4T, etc etc it's a bit confusing 🤡🤯 thanks
Hi everyone. Totally new to trials and Totally new to beta. I just bought a cheap and cheerfull 2007 rev4t 250 4-stroke. The clutch is dragging and it seems to then when driving it has to be let out completely then it engages kinda sharply. Anyway I found a few hints where you file the glue off the friction plates and polish the little dogs on the plates so I'll try that. But the lever is a bit sloppy and the screw that pushes the piston in the master cylinder is pushing at an angle? There's a small leak there too. Having a little trouble finding a master cylinder rebuild kit for it, hard to identify my master cylinder? Any tips appreciated. I'll add photos of master and of the parts that don't seem to line up.
Ah thanks. I'm going to do all fluids and filters before riding. Looking to rebuild clutch master as it's dragging and leaking at master! Fork seals are leaking and front wheel bearings are gone. Looks like petrol is weeping from somewhere under tank. That tap on the tank looks to be broken or different from the manual too. Loads of little bits to do. Thanks for help.
Hi everyone. I'm totally new to trials, and to fourms! . I just bought a 2007 rev 250 4-stroke. All I could afford at the moment. I'm just wondering where would be the best place to source parts? I can't seem to find anything on line. Every search seems to throw up parts for the 2504t RR )which I assume is a beta enduro bike)? Or the 2stroke trials, but not the 4stroke. I want to service it and do fork seals and replace a few bits etc. Thanks in advance Noel.
