  1. I run a 428 chain on my TY250 twinshock with no problems - it is how it came out of the factory. Mick Andrews was very frank with Yamaha about the TY range,got his own way over most of the design. Looking at how little needs doing to a TY compared to other brands of the time I think he and Yamaha did a very good job. There was a time a while back when it was popular to fit mono forks onto the twinshock TY's, then most went back to the originals as they felt the leading axle of the mono ones spoilt the steering. The progressive springs are the way to go as you already have.
  2. The best long term solution is to get a 21" rim laced onto your hub. You then will have plenty of tyre choices, from road to full on knobbly.
  3. Give them a break ! Its a small operation, staffed by a friendly bunch of people. They do a good job.
  4. I had a pair of Falcons on my HT5 Ariel, they were very good, would thoroughly recommend them. The only bad experience I've had with rear shocks is with Betor's. On one of my Ty250 Yamaha's I had a pair which leaked within a few months from new. But they worked better when they had leaked, so I carried on using them till I sold the bike.
  5. It varies every year, but even the bits of main road we have used in the past are very quiet with little traffic. It really isn't a problem.
  6. The Arbuthnot varies in length, usually between 70 and 80 miles, although one year we did 90. There are no garages on the route, but there is a trailer which will take your fuel can to the lunch stop at the golf course. We always have lunch in the club house with a pint, then oil chains, refuel and a quick check over before setting off again. You need a good air filter if its dry, most of the distance is on old drovers roads which can be very dusty. Its a great day out,lots of nice bikes and a very friendly atmosphere.
  7. Have you seen the Talon Mickmar in Sammy Millers museum ? By chance I was there yesterday, but didnt take any pictures of it.
  8. I run a 9e clutch in my James J9 with an Albion 4speed box, the 9e clutch is a great improvement over the original, it was supplied by Paul Powell of Cotton Villiers services - very helpful.
  9. This stuff - https://www.elfcompetition.com/produits/cs23005_uk.pdf Mmm, I'm no chemist, but I guess its heading toward the same goal. The specs don't really give much away...
  10. For the same reason we don't have electric 44ton trucks, the batteries are nowhere near there yet. The electric chainsaws are small domestic use types.
  11. The only thing I would add to this thread is about Aspen fuel, I use it in my chainsaws because it does not wreck my at least 30 year old kit. But mostly because the fumes from it are much less toxic than from ordinary pump fuel. I used to get terrible headaches from chainsaw fumes after as little as 20 minutes sawing in still conditions. Since using Aspen I don't get them at all. I still have a couple of tree surgeon customers who use it because they have a duty of care to their employees. They are worried about asbestos type comebacks on their insurance, plus they don't want headaches either. I understand that the HSE have approved its use for petrol engined wacker plates in railway tunnels. Which helped Network rail and their contractors no end because previously they had banned them.
  12. Sorry, but you are wrong, the ethanol in the petrol is destroying fuel pipes, the worst case I have seen is 6 month old "Ethanol resistant" fuel hose that became porus and leaked like a sieve. Plenty of diaphram type carbs on strimmers and chainsaws etc, have been wrecked. It is a pain in the a***.
  13. I use a BTH electronic unit on my rigid AJS, it is reliable and more accurate than the Lucas racing mag it had before. Go to the Talmag and you will see loads of them there. Not cheap, but worthwhile if you want a good spark at the right time,every time. I have nothing against mags, I'm going to a VMCC meet on my ex WD G3l tomorrow,happily running on an N1 Lucas. But for trials its a new BTH.
  14. A promise not to post 4 hrs ago, and already 3 more... I enjoy a healthy debate, but this has gone beyond it. Woody, all the way through this thread has made honest,sensible and very well thought out responses, which TT Spud refuses to accept, he seems to be living in a different world of, (Very) occasional trials.
  15. TT Spud, twice I have asked you who is going to do this scrutineering and how should they be qualified ? It is hard enough trying to get enough observers, without trying to find extra staff. many clubs offer money to observers, but they still struggle to find enough, or in some cases apparently people have taken the money and disappeared. So who is going to be the scrutineer ? I for one would not want to stand in a field on a Sunday morning trying to tell a rider that this petrol tank or front hub is not acceptable - So you need to go in a specials class. You need to start your own club and see how many riders you get.
