found the circlip pliers, It looks corroded to me, The waterpump housings looks like it is a part of the clutch case, can you buy it seperate or do you need a whole new casing? Or do sealing products work?

Could you do one about stoppies? Don't know if they'd be helpful to know in a trials section, but it would be cool to learn

Thats_a_five: thanks. I'm starting with the water pump. I've got the housing off and have included a pic of what it looks like. Sorry but I couldn't get the circlip and impeller off. Does it look corroded? I know it's a bit silly to ask but I don't know what I'm looking for.

I would if I could, haha. The enduros around here are that price, the trials are £12 to enter, £10 a year membership fee- so not too bad

Thanks for the reply, I really appreciate it I wish I had been more careful and had noticed the oil was white in the gearbox before buying! Never mind, it is fixable so it's not so bad. Seems like it would pay to be thorough, I'll get a new clutch case o ring, inner clutch cover gasket, water pump shaft seal and the shaft. The links were very helpful, especially the article with the pictures, that's made things clearer. The steel plates in the clutch were showing signs of corrosion, so I need to get these filed smooth and some new clutch friction plates? I can afford the parts but not the labour costs of a mechanic. I can do basic stuff, how much trouble can I get into with this job? Hi thats_a_five, thanks again. I haven't run the bike today, that pic is of the bike cold. She has had 4 oil changes in the last week. Thanks for the advice about the oil level, and no to the puddle underneath the bike, it is weird how it has gone down. As for the kicking, it was down to technique. If I bend my other leg and use my bodyweight it's a lot easier ta thanks jfc

Thanks for the advice. This is how the oil is looking today, Should I just keep changing the oil to see if it clears? The oil level had come down too and I had to top it up. Coolant had gone down by about a quarter of an inch since last week.

Thanks for the responses guys. I've had a think, it's 38 pounds to enter and 90 bikes have signed on so far. I'd rather enter a trials at the end of october and use the bike for what it's built for. I'm going to give it a miss and go down to my friends farm to practice instead and then get the oil/water problem sorted next week. Thanks again

that's really cool, hats off to her

At least the mud will be soft in the event of a fall, hehe. Thanks for your input, I guess if I take it easy on the straights the engine should be ok. I'm not likely to be going flat out every where any ways. There will be an assortment of bikes going round (pit bikes, classics etc.) sidecars and quads too though.

Hi, There is a local enduro on this Sunday, I want to enter it but I don't have a big enduro or mx bike but want to go out and get some practice regardless. I'm not that comfortable with speed, I thought a bit of competition might get me going and improve my confidence. This enduro is classed as a 'gentle one' about 3 and a half miles long, fairly easy going but could get real muddy with the 80 odd bikes going around. I think it's an hour and a quarter one way, then the reverse after lunch. My beta is quite nippy up in 4th and 5th gear, and I figure it would be good to go on a longer run with it to build up some endurance before my first trial. The enduro isn't part of a championship or points or anything like that. But I am concerned I won't be able to keep up with the other bikes and might get barged past. Plus I'll probably be the only one on a trials bike there. I guess my question is, has anyone here entered an enduro on their trials bike? And if so, how did you find it?

I'm going to check the coolant level tomorrow, as the oil became milky again today. It does seem a little silly where the crankcase breather is on a bike of this type, I'll take your advice, thanks. If it is the coolant, is it most likely the water pump housing that the leak is coming from? If so, does anyone have a link to how to fix the problem or know which parts to get before taking anything off the bike? Aside from the clutch and gears issue (which goes away when she's warm) the bike has good compression and runs well. I just want to sort the problems that are there, I don't want to put the cold drag issues down to 'it's a beta, what do you expect?' It can be improved i'm sure

Thanks for the advice. Running the bike in gear every day is not really an option because of where I live (no MOT for the road). I am planning to travel to a friend's farm at least three days a week for practice though. The cloudyness in the window has gone now she's not running, the oil looks much better. I'll check the coolant level in the morning and double check for any leaks. Thanks for the advice. Spent about 2 and 1/2 hours filing the glue off but no, I didn't bevel and sand the tabs, maybe that's the problem. I'll change the oil again within the month and watch the coolant level. A white film around the edges of the sight glass is about right, but it has improved with the oil changes. Hopefully it isn't porous cases or the pump seal leaking. Thanks, I'll give this a go 2 miles is a long way! I think the previous owner hasn't used the beta for a while, plus power washed it down too. Bolts are tight as hell! The whole bike needs going through and greasing, which is what I'm planning to do over time. Not to mention they put the wrong spark plug in! If I never see a damned allen key again I'll be happy, haha!

Hi, I've just bought a Beta Rev 3 200cc 06 last week. I've done the clutch mod to the bike (filing down of the glue). The gearbox oil was white, I thought water had leaked in through the clutch case o ring which was too large upon inspection (which I cut down and attached on with some silicon). I have since changed the oil 3 times, the oil got clearer each time, but the sight glass on the side still got cloudy running her with the last batch of oil. I thought the coolant might be leaking in (people on the site have told me about the magnesium casing corroding/ water pump seal problems). But the coolant level hasn't gone down much since being filled. There don't seem to be any oil leaks or cracks either. I put her into first gear tonight with the clutch pulled in and she lept forward and stalled. She's also quite difficult to kick over. I just want to get the bike running really well and maintain it for good use, and hopefully not have any disasters during a trial. So any help would be appreciated, I have limited mechanical skill too...
