  1. You most likely have dirt down in the seal. It happens sometimes. You need one of these: http://www.ebay.co.uk/itm/Seal-Mate-Tool-Fix-Leaking-Fork-Seals-Quick-Easy-Fast-Affordable-BLUE-/172572962991?hash=item282e2670af:g:BrYAAOSwve5XOFnS Watch how do use it on Youtube,
  2. I'm 16 stone. I ride a 2014 Sherco ST 125 every week in a trials competition at Novice level. I had two 250 Betas previously, the last being an Evo. I like this 125 much more than the 250s. It is easier to ride and control than the 250s. It FEELS lighter and more nimble. Is less likely to wash out on tight downhill turns, or rear up when suddenly finding grip on steep uphill sections. It won't really plod along, like a 250 will, so you keep the revs up a bit and slip the clutch. It has a power band, so you need to keep the revs within that band, if you want power - it is a slightly different technique than riding a bike with a bigger engine. (I have my tickover set high, which helps). Mine does not like long lengths of deep, sticky mud, where 3rd gear might be the best to use - it won't really pull it. Long, steep hill climbs, in 3rd are not on either. I recently had a quick ride on a brand new Gas Gas 125 Racing. That was even better than the Sherco 125, because it had more low down power and torque. I would buy one. (The older Gas Gas 125s are not the same, apparently).
  3. Do IRC rear tyres still come off the modern Motad-style rims when inflated at very low pressures, 2 - 3 psi? If so, then why don't the manufacturers make the bead a bit smaller/reduce it's circumference?
  4. A qualified First Aid person should be essential at all trials events. I am surprised that is not part of the conditions of the insurance cover for trials events..
  5. That's the problem with high technology - not suitable for us "shade tree" mechanics.
  6. If the box has been cut, then re-packed in the past,as outlined above, it could be that the new cover plate is loose, or not sealed properly.
  7. I wonder if this will come to all riders in the UK eventually, not just for Junior riders?
  8. Why not put them on Ebay or Craigslist and sell them - one at a time, rather than as one lot. Or, take them along to your next trials meeting. People are often selling bits and pieces at them.
  9. I ride a Sherco 125 every week in a trial - perhaps now around 80 trials on this bike. However, in the past I have always ridden 250s. The thing about a 125 2 stroke trials bike, compared to a 250, is that it completely lacks torque at the bottom end. Consequently, when ridden by an adult, it is necessary to rev the motor and slip the clutch to obtain power and torque. It is there, but not at or near the bottom of the rev range. The latest GasGas 125 is a bit better than the others IMHO, but still nowhere near a 250. I don't think that the limited power of a 125 needs a heavier flywheel to smooth the power. However, it might contribute something else to the power characteristics - perhaps slow down the time that it takes to rev up and therefore slow down. Why not fit one and report back.
  10. Before you do anything else, use one of these: http://www.ebay.co.uk/itm/Motion-Pro-Seal-Mate-Fork-Tool-Motocross-Enduro-Husqvarna-CR-WR-TC-TE-449-450-/152435574729?hash=item237dde47c9:g:y4EAAOSwmfhX7TkO Look on Youtube for instructions.
  11. Aged over 60. Ride in over 50 competitions a year. Rarely practice. Usually Novice, rarely Clubman. Always for fun!
  12. I was talking to Jon Bliss a while back, while waiting at a section. I asked him about spares for the motor, He said that if anything major occurs, then you just spend £180 on a brand new engine. However, he said that the motors are very reliable. Two or three similar bikes (they are all slightly different) built by Jon Bliss regularly compete at Clubman level in the South West. They are competitive alongside modern Monoshocks and obviously with Twinshocks. Most of these bikes from Jon have the fuel tank in the top tube, like this one:
  13. The rear brake on the Techno that I used to own would fade out during a trial, whatever I did. I met a chap a year or two ago who had completely replaced all of the rear brake hydraulic system on his Techno (not the caliper bits) with brand new bits that he had bought from Australia over the Internet.. Apparently they then worked. Also, behind the bleeder nipple on the rear caliper there is a small ball bearing, which acts as a one way valve. This might be missing.

    2015 Sherco 300

    Nothing wrong with the fuel tank in the rear - lower down, so a much lower center of gravity = improved handling. The fuel pump is old, well-tried technology and is reliable. Have a look here:
  16. Some of the Cubs that he builds don't even have those thin engine stabilizer bars. Here is a link for anyone that is interested: http://www.bsaotter.com/the_mini_otter_project..html
  17. I'll wager that you are also one the gentlemen that always pushes in when queuing for a section. That is also poor etiquette. Bad manners too.
  18. Why do some thoughtless people leave their engines running when queuing for sections? I can understand it if the trial has just started and they are warming their engines up while queuing at the first couple of sections, or if their bike has suddenly developed a starting issue. However, some people routinely leave their engines running between sections. Exhaust fumes are carcinogenic (causes cancers) and so you don't want a dirty two stroke exhaust inches from your face, blowing poisonous fumes into your lungs. I have asthma and this always brings on an attack later in the day, meaning breathlessness and no sleep for me that night..
  19. I would like to see Triumph make a copy of Jon Bliss' twinshock Cotswold Super Cub. Perhaps using a titanium frame and a Triumph built/commissioned copy of the Chinese motor, with FI and a full-length bash plate. Mono-shock, discs etc obviously an optional extra. A very capable bike in the right hands.
  20. At the trials competitions that I go to every week, I estimate that there are typically 10 two strokes to one four stroke - something like that. This must tell you something.
  21. None are really better than the other. All down to rider skill really. A 125 is MUCH easier to control than a 250.
  22. Sherco, Gas Gas, Beta. They are all good - new or second hand. Don't bother with a 4 stroke until you gain some experience. 250s are the most popular by far, but a newcomer to the sport, or an older rider will find that the late 125s have more than enough power.
  23. And also catering for the Over Sixties riding modern bikes?
  24. I rode in the Hex Hill trial and on my 4th lap I thanked all the observers, as I always do, so it has become a habit and I do it automatically. I can understand how a person could forget, but over 50%? The Over Sixty riders might have a valid excuse, with failing memories due to their advancing years, but they were in the minority. Some south eastern clubs use hole punches and riders self-score themselves - not ideal for several reasons, in my opinion, so we need to keep both the organisers and the observers happy. Remember to say thanks because politeness costs nothing.
