Aaron, do you know where to get them though?

Gez, first of all, post some pics of your bike as you have the same bike as myself and beta boy. You can see pics of our bikes under the topic 'rear mudguards' in the beta forum. I think you get different sizes of bleeding breaters, if you can find a larger size breather you should be able to tap out a larger thread and install the bigger size of breather.

Wow, check this out..... http://www.arizonatools.com/catalog/browse/3012-3009/ ...so many.. p.s. Perce, love your avatar!

I have been letting my tyre wear away my exhaust (not deliberately) and there is now a big hole on the side. Does anyone know if it would be possible to patch this? I was thinking along the lines of riveting on a patch of similar metal and adding some gasket paste round the circumference. I don't have easy access to a welder.

The above comment is probably the quickest way to remove the bolt. Be very careful when choosing which extractor (easy-out) you begin with, don't go immediately with the smallest one (like i did). These tools are very brittle (like a file) and if you snap it off inside the drilled hole, you'll never get the plug out. Choose a size that will be big enough (with relation to the plug size) that it won't snap, but small enough that if you can't get grip, you've enough room to try the next size up. Also spend a little more and purchase a decent set of 'easy-outs', that are less likely to snap (and will prove to be a valuable asset to your tool collection).

Stu, i should have been more clear (was p****d when adding the comment!). They are nylon nuts that are only used once then thrown away. See here: http://www.screwfix.com/app/sfd/sea/search...=1&cd=1&x=0&y=0 Dunno if you can link to the above, if not go to screwfix.com and search for nylon nuts. If it's the same bolts (countersunk?) as the techno, i think it should be an M8. You could also try using two nuts, (dunno if you would have enough room or a long enough bolt) one acting as a locking nut!

Couple of suggestions James if you haven't gotten it out yet. You could try chapping on a slightly larger allen key socket (or torQ might fit) onto the plug, at a risk of damaging your socket though. You could also try hitting it at the right angle with a small chisel or punch. Start your bike and let it heat up, when this is happening try using your chisel every few minutes as it heats up, try again as it's cooling aswell. As for your icecube theory, when your engine is hot and you then try cooling the plug with the cube, you will have a larger temperature differential and hopefully increase your tollerences. Good luck.

have you tried using nylock nuts?

Does any of you Sherco owners have a photo of a 99/00 rear mudguard (off the bike) that you could send me (or add to this post). I ride a 95 Beta Techno 250 and the rear mudguard is made of very brittle plastic, therefore always breaks. Apparantly the above mudguard should be able to fit (see pic on recent beta post). Is this mudguard very flexible? From a photo i might see if i'm able to convert it so that it fits my bike. Any help greatly appreciated.

beta boy, where can i buy the cabon fibre sheets that you have on your bike? Is that

Eiger, have you got a photo of your chain breaker? Do you think it would be easy enough to fabricate? Cheers... FM.

and trials bikes in general??

You win! Are trials bike a plenty down you way? There pretty rare up here.

Bought it about a year ago. When did you buy yours? What did you pay?

pricey?????????????

Tidy machine beta boy, wish mine looked like that. This is what my bike looked like at the garage when i was looking to buy it. You'll see the price tag too, i paid slightly less than that (SlIgHlY). Bike looks nothing like that now, part from the dirt, pop-rivits all over the front & rear mudguard.

Spent about 3 days trying to drill it out beta boy, there are now titanium, cobalt & HSS bits broken off inside the hole. Think i'll need diamond to drill though it. I tried starting with smaller bits but they just broke off too easily. Guess i was too desperate to get out on the bloody thing. P.S. Beta boy, you not getting my PMs/emails??

power devil..

FYI; Purchased Iris chain & Talon sprockets from Tony K @ <mention of this company is not permitted on Trials Central>/trials.html Cost me

This is what i've done in order to get a second bolt into my bracket/frame. The black cross on the upright is where i will drill the new hole, you can see the rear hole just to the left of the new upright. These are hebo pegs, if anyone hasn't see them before! Twice as wide as my previous factory pegs. Does anyone think this new hole will be a bad idea? Will it considerably weaken my frame? Cause a... eh.. fracture?

I keep on breaking my rear mudguard on my 95 techno. At the moment there is about 200 rivets, 150 tie-wraps and 3ltrs of evostick on it. Is there a ultra bendy, after-market mudguard i could purchase ?? Or any other durable repair technique?? Cheers FM.

just found this site, gives you info on re-inforceing your bracket http://www.places2ride.com/trials hope it's of some use.

cheers ishy

My old chain kept coming off and wrapping round the front sprocket, i guess i'm lucky i havn't broken something in the gearbox. When i get my new chain & sprockets, how tight should i have the chain?

i ride a 95 beta techno 250cc, i tried to drill out the bolt which is stainless steel and i ended up snapping drill bits in the hole. I made a right mess of it. Make sure you use proper COBALT bits when drilling out SS, don't be tempted by cheap bits, or even half good HSS bits. I think i'll have to adapt my bracket with a welded-on piece of steel and drill a new hole about 1" above the existing front hole!!
