https://www.feked.com/wheels/tyres-and-tubes/trials-tyres/page-2/ I think these might be the right size - just happened to be looking on this site for something else and remembered your post.

That's a really interesting idea! Very simple concept and makes sense to me. If it's not slipping then you have struck upon a great solution - I will be planning something similar for my Beta I think! Thanks for sharing.

yes anticlockwise all the way is off, up is on, forwards is reserve.

Hi Tom welcome to the forum - too far away for me to be any help but I hope you find some local riders. This is a great place to pick up tips and advice. Good luck.

2 all the way!

I got it! maybe it's because I have a Beta (yes...and I'm probably the other thing before anyone says it!). Perhaps you should canvas a lot more opinion and you can also have a mass debate?

HI - There was a fairly obvious "rough" noise from the case when running - it did actually run quite well but starting was very difficult.

Mine was getting hard to start as my main bearings were worn. After replacing them it was a very different bike. I also agree with others that there is a bit of a "knack" - I use the kick lever to slightly turn over until max compression is felt, then as described above, raise up with a bent leg on the lever and apply a brisk and firm "kick" by straightening my leg and descending at the same time. When cold I use the choke and no throttle. when warm just a bit of throttle.

If you join a club you may find members selling bikes in that price range - probably a good opportunity to try a couple and find out a bit about the history - possibly also less likely to be sold a pup if the seller knows he/she will see you every week thereafter?

Thanks Andy - that works fine - I didn't see the drop down part before as it appears in the lower part of my window and I needed to scroll down. Thanks, Mark

Hi, I wondered if anyone knows how to search a specific forum using the search tool rather than the whole "community"? I am sure I used to be able to do this but haven't felt the need until today, when I realised I couldn't. I wanted to read about Beta pistons. Perhaps someone cleverer than I can help?!

Well done Rich! I bet you'll be riding round and round that bench all weekend!

250 should have plenty of power. I think that any water pump issues would have occurred by now and been dealt with - I got a 2007 270 a couple of years ago and it was clear that it had a new casing - looked newer than the surrounding components. I'm sure any water ingress would cause a milky appearance in the window. Good luck with it - they seem quite robust bikes and certainly good enough for a beginner like me and even if bits go wrong there are many spares around.

HI Dave - welcome! I'm in West Sussex and joined the Bognor club - very friendly bunch and made me feel welcome. Practice once a month at Halnaker and various trials when you are ready (I never feel really ready!!). Good luck, Mark

assuming the coolant is not too full (in which case it will spit) and assuming your fan is running, I guess you might have a problem with the pump or some kind of blockage in the system. Maybe a good idea to take off the cover and have a look (after draining)

I was a Product Design teacher for far too long! and recognise the need to identify a rewarding project at the start of the year. Many parts (most/all?) of a modern trials bike are now highly evolved so I suspect it will be hard to identify any modifications that the manufacturers haven't, but there may be some mileage in identifying equipment for training needs, or perhaps accessories. You might also think about kit storage/transport to events. Maybe a way of helping observers to keep score in the rain? I'm sure there are loads of areas related to trials that you can work with. If you need any advice, I'm happy to help. Good luck!

You've made a beautiful job of that pedal arm - nice work!

that's a smart looking bike! Good luck with it - you'll have lots of fun.

I have a 2007 270 and it was just the same - you sound mechanically knowledgeable so don't be afraid to have a go - it's a relatively simple job to access the clutch as described already - I did the mods described in the Beta forum and still have the odd time when it jumps after selecting a gear - I don't know how Beta got away with a design that does this, but it seems that everyone has the same or similar issue. It can be improved but I'm not sure it can be completely solved. I just make sure I have the brakes applied when I select a gear for the first time - after a very short while it warms up and everything is normal again.

I'm enjoying all these - and the reassurance that it isn't only me!!

I used to have a DC rack on a regular flat plate type towbar and found it worked well with minimal flex etc. although the forces involved must be pretty large (I'm also pretty sure insurance would use it as a loophole to avoid paying out if anything occurred). The problem with those ratings (650kg) are that they are probably the downward load force measured at the towbar - introduced by a trailer or caravan etc. What the DC rack is doing is applying a turning force or "moment" which is the combined weight of bike and rack multiplied by the distance from the ball to the centre of gravity of said bike and rack. The only way to counteract this is Oni nou's strap idea or Nebulous's extension bar under the car. I expect the bracket has some plates which contact the neck below the bar, but they will be very close to the pivot and won't really be able to balance the force from the bike.

If there is such a thing, I feel I should nominate myself! .... Just getting my bike ready for trial this Sunday (should have done all this after last time, I know) - quick clean, changed filter, checked fluids, pumped up leaky rear, filled up fuel...all the usual stuff, then thought I'd just start it up. Nothing!...I tried choke in, choke out, not a chance. Took plug out and checked/cleaned it, still no joy. Cleaned out carb...Then I spotted the problem... no lanyard fitted! Derrr. Two kicks and a massive blue cloud later it was running sweetly! I guess it's the simple things sometimes!

welcome! nice bike - I'm sure you'll have loads of fun with it (and there are lots of very helpful members with lots of knowledge about Rev3s on here, which has been great for me)

aye....and we used to live in a shoebox int middle o't' road..!

don't ride without boots - I tried it when I got my bike (before I got boots and I couldn't wait just to ride around the back garden) - its amazing the damage those footpegs can do to your shins - even of they look rounded!!
