  1. Evening folks hope you are all well, my lad has managed to get an entry into this years Scott trial and I’m hoping to get some advice on what will help him finish. I’m told a Dunlop rear tyre is a must as they don’t fall off the rim easily, plus I’ll need a few extra fuel cans, if you can think of anything else which will help it’ll be much appreciated. I’m looking to source him a TRS as it what he usually rides. Many thanks. Pete.
  2. Evening folks, my mate has just started out in trials after years of me badgering him to give up golf…! He’s got a Beta Rev 3 with a frame number of ZD3B9000010005063 Am I right in thinking this is a 200cc (he bought it believing it to be a 250 although he’s more than happy with it) I’ve struggled to find any exact information as Google throws up so much stuff it’s hard to see the facts. Any advice would be much appreciated. Thanks, Pete on behalf of Ruprecht.

    315R engine number

    Thanks pjw123, much appreciated
  4. Could any of you helpful folk tell me where I can find the engine number on my 315R as I’d like to register it for road trials and Montesa Eu want both the frame and engine numbers, thanks in advance.
  5. I'd be grateful if anyone could advise on rear shock absorber choice and length for a 1960 C15 trials bike, previously it had a strange rear subframe concoction but I've fitted a new rear subframe from Progressive Classic Products which is far more trials orientated and has also now allowed the exhaust to run inside the subframe without fouling the tyre. Any advice much appreciated, thanks. Pete.
  6. Thanks for the information folks, so much help on this site as always.
  7. Evening folks, I'd be grateful of any advice for two problems, the first is in relation to a Triumph piston which I've bought from Burton Bike Bits as an upgrade for my 1960 C15 I've had the barrel rebored to 69mm but on fitting the recommended Triumph piston the gudgeon pin is too tight in the little end, it'll fit but far too tight. Do I need a different little end bush or is the con-rod just incompatible? The other problem concerns the clutch actuator arm, where the clutch pushrod seats into the barrel in the arm, the barrel has a pin through it but the pin carrier has sheared and no body has a replacement part, I could fabricate something solid but it looks like a bearing should be there to prevent wear at the end of the clutch push rod when it rotates in the carrier. Any advice much appreciated. Ta. Pete.
  8. Good morning folks, I spent a few days in Scotland at the beginning of the month watching the Pre 65 event and it's re-ignited my enthusiasm to get my 1960 C15 sorted and I'd be grateful of any advice. The rear frame loop where it attaches to the frame in front of the seat is welded which looking at the parts manual isn't standard as they appear to be normally bolted through a bracket between the tank and seat. I'm hoping that one day my entry for the Scottish pre 65 will make the ballot, would the frame as it stands make it through machine examination? I've fitted the smaller front primary drive gear and it has a 13 tooth front sprocket, the rear sprocket is 62 teeth and it needs replacing can anyone suggest where I can buy a new rear sprocket and what the optimum gearing should be. I've also fitted new electronic ignition but the bike 'cough stalls' quite a lot and I'm wondering if I should look at renewing the carburettor, the one fitted is an Amal 375/34 but again I'd be wanting one which is Scottish acceptable. I'd also be grateful of advice on footrest mods or are these best left as standard and also the best exhaust set up, the current exhaust runs outside the frame. Thanks in anticipation!

    1974 Ty320

    Thanks for the replies: 0007: I'm not sure if it's pre-ignition or detonation but it makes a harsh knocking noise especially when the engine is under load and warm, on initial start up from cold it's fine but within a couple of minutes it starts and is there at any throttle opening apart from very low gentle revs with virtually no engine load but if I put the choke on when warm the problem almost disappears. feetupfun: I'd be grateful if you could let me know the jetting specs for the TK carb at least I'd have a base to work from, thanks. mickwren: I appreciate Nigel has a vast knowledge of virtually anything trials related and has previously sorted bike problems for me but he's such a busy and sought after bloke I thought I'd give him a break and put the question to a wider audience. that's_a_five, b40rt and 2stroke4stroke: I'll renew the points and condenser and check the timing, I've been told by a previous 320 owner that adding a second head gasket to reduce the compression will also help so I'll try that too. toetoe: I'll have a look, thanks for the info. Thanks again for the advice folks.

    1974 Ty320

    Good evening folks. I'm in the process of rebuilding an American import 1974 Ty 250 which turned out to have a 320 piston and barrel, it had a fair amount of piston slap so it's been rebored by Nigel Birkett to second oversize and is now up and running. However, it suffers from pre-detonation, a leaded additive for the fuel has helped but it still bangs away sometimes and is fitted with a black coloured 'JT'carb'. Would anyone be able to point me in the right direction and confirm what carb and jets it should have as well as how I stop the detonation? Many thanks. Pete.
  11. Henrik We had exactly the same problem with my son's Evo 290 it's a 2010 model, we contacted the importer John Lampkin to price up a replacement. We returned the old unit and received a replacement and the only cost was the carriage, the shock and spring unit was replaced free of charge, excellent service from the Beta UK importer. May be worth speaking with your importer as there have obviously been some issues with the shock. Regards Pete
  12. Try not to advertise the fact you have a bike, plastering a van in bike stickers and leaving it parked outside your house is an advert to the low life thieves. Same with travelling to and from an event, be aware of being followed. Use hardened steel locks and chains (expensive but worth it) with a good quality ground anchor sunk into concrete. Utilise security lamps which are out of reach and have a mesh guard to prevent thieves using a pole to reach up and move the PIR sensor out of the way. Paint garage/shed roofs with anti-vandal paint and use good quality locks on doors and windows. Make sure perimeter fencing is secure, screw fence panel's to posts to prevent the thieves from sliding them up and out of the posts and additionally attach the concertina type trellis to the top of the panels to prevent them climbing over, they are unable to get any purchase and if attempted they trap fingers and make a hell of a racket. Surround any possible approach route with gravel so they are unable to make a silent approach on foot. Don't leave tools like hacksaws, grinders, cutters readily accessible should entry be gained by the thieves. Use a decent alarm, we keep our bikes at another address about half a mile away, I've fitted an alarm with a built in sim card which phones/texts up to five numbers of your choice look up www.novibo.com they do add-ons which can you can use to personalise the system to your choice, a cheap and very good alarm - It's stopped our bikes going on two occasions now. I'm nowt to do with Novibo it's just the alarm I bought, there are others on the market undoubtedly as good or better but for the price I was impressed by what was available. Report illegal bike riding to the cops every time you see it, most of the time they are on nicked bikes. Report every incident of suspicious activity, attempt theft or burglary or damage to the cops and complain if you get what you perceive to be poor or inadequate service. Mither them until they start to address the ever increasing problem of bike theft and hammer your local councillor and MP until they realise we should be getting tough with thieving scumbags instead of allowing them free rein. Good luck.
  13. The Bemrose has always been a fantastic trial, I couldn't make it this year through work but my parents observed and enjoyed it too and several friends competed and all thoroughly enjoyed the day out. The stalwarts behind this event who have been organising superb trials for many years do not deserve the kind of comments above, mistakes are made by all of us but sometimes we don't have control over the actions of others, trials are usually always run by a small number of volunteers who are prepared to give many hours of their own time for the benefit of others. Constructive criticism is fair but not when fuelled by anger and the author of the above comment (who has and does commit so much of his own time for the enjoyment of others) should really know better as without the likes of him and the organisers of the Bemrose we might as well give up. Pete.
  14. Houseape, as a serving cop I agree with some sentiments but really despise cop bashing threads from those who do not have a clue, I have arrived at jobs within 5 minutes on many occasions and often when the report has been of a burglary or robbery but what you don't see or understand is what happens in so many cases We are driven in the main by home office measures. I joined the cops to catch the scumbags who steal your car or bike. Or break into your house, assault your elderly parents or grandparents and take money from them but regardless of my ideals we, as a country, are financially motivated and those of us who can pay will pay and those in power will ensure that will not change. I've posted before on here about what i struggle to come to terms with in my job, I'm 47 yrs old now and have been in the job 17 years and have seen many changes but close to 4000 people each year die on our roads from mainly speed and/or alcohol related deaths, a lot less die as a result of burglary or theft so there has to be a balance. If you get rammed up the backside tomorrow by an uninsured and unlicensed driver which will cost you a lot of money you may feel differently as you would if (God forbid) someone close to you was injured by one. My argument is that we don't seem to have any consistency and the penalties for committing crimes can in some cases be so severe (mainly where the government lose money) yet so meek and mild where scumbags get away almost scot-free for burglary, robbery or theft. I work mainly ten hour shifts and since the inception of the new 24 hour drinking laws now rarely get chance for even a brew in a shift but I accept that compared to my previous job as a mechanic I get a good wage, shame our lads and lasses in Afghanistan don't. And so you know cops are on performance indicators which means they have to get a certain amount of ticks each month (as an example a traffic cop will have to get so many no seat belts, speeders, mobile phone users etc) but with no reward only to keep the job they are in. And if you think its bad now the penalties for those that can and will pay for misdemeanours will increase soon to help with the financial defecit the western world faces. Rant over (for now) Sorry Pete
  15. Had exactly the same problem with my lads Beta Rev 3 and after replacing the key it sheared again but that was down to me not tightening it up enough as if you look back through other threads the torque setting for the flywheel nut on the Rev 3 is around 103 ft/lbs. And since then its been fine as it was for 18 months prior to shearing. Check what the torque settings should be but it seems if they are set as per manufacturers instructions it should solve your problem.
