    Is it possible that this situation has been brought to a head to secure some of the Euro bail out money to wipe off some of the bank debts. I don't pretend to understand how this system or process works, but maybe GasGas is eligible for some of this package?
  2. I have never had any trouble getting Bultaco aluminum alloy welded. Over the years I have had a fork leg welded, several cases, a fin off a head, a fin off a barrel and the last bike I purchased had been pulled apart as the lug that sits behind the countershaft sprocket [rear mounting lug for the ignition side case] had been broken off leaving a hole in the main engine case. I have used a couple of different welders over the years, it pays to do your research when choosing a welder as well. I always make it as easy as possible for the welder by making jigs if necessary and by always dressing the area to be welded, then heating it gently with an oxy torch to burn out any oil etc and then cleaning with wax and grease remover and a stainless steel wire brush. Take your time to find a competent welder. I have previously used a fellow who was making bits and pieces for turbo cars - manifolds, airboxes,etc. Currently using a guy who works in an auto radiator shop repairing radiators, he also does one off fabrications for modified cars, 4wds and bikes. These guys are very skillful and the work I have given them has been a 'piece of cake' compared to what they normally do. By the way welding the lug back on to the engine case was a lot of work for me [shaft in position in case, cases bolted together, plate on the outside to secure the lug in the correct position, prepare the weld etc, a days work for me] the guy took about five minutes to weld it back on and charged me $40. Cheers Greg
  3. Trying to repair that gap by welding will create more problems than it solves, I would glue some sheets of various grades of emery paper as well as wet & dry to a flat surface[glass is great] and then work the case over the varying grades until it is flat. I am pretty sure there is enough clearance for the clutch. Worst case scenario you may have to make your own gasket out of thicker gasket paper to compensate, but I doubt it. Cheers Greg PS I have had all sorts of Bultaco aluminium alloy parts welded without any problems, the welders usually comment on the good quality of the alloy used.
  4. I have tried quite a few different pegs and find the standard Hebo ones fitted to the Gas Gas to be the best in terms of abuse taken and usability. I have recently tried the S3 Hardrock pegs and have ended taking them back off as I was getting my foot caught on the allen headed screws. This happened several times, so I asked a couple of mates to have a go and they found the same thing. I may try to grind them down at a latter date to stop the problem, also tried some aluminium pegs a while back and they need sharpening at regular intervals to keep an edge. So all in all I am back to the standard Gasser pegs which require no maintenance and are basically indestructible. Cheers Greg PS beware of buying steel pegs that look like the Hebo pegs as they are about half as durable
  5. 'In Motion' sell the bracket or the complete peg & bracket. Cheers Greg

    The flywheel should be rotated counterclockwise when checking the timing. To retard the timing [from 3mm to 2.75mm] the backing plate should be rotated counterclockwise. Cheers Greg
  7. Yes, I have a 199A 325 Bultaco I compete on as well. As much as I try I cant bring myself to ride the Bulto consistently in the modern style and basically end going back to the clutch out use the throttle style of riding. The clutch is one finger, but the weight and poor brakes make it difficult for me, anyway, to ride it modern style. I know one thing however a day on the Gasser is a lot less tiring than a day on the Bulto. Cheers Greg
  8. I didn't say it was an incident, just pointing out what happened. Fuji spent more time with the laptop than Bou and I saw him foul plug on the Saturday during the event.The factory Hondas also had a lower idle in my opinion so I would assume they have a better system than on the production bike.
  9. I would love to have a fuel injected bike that ran like my FI cars. However the current FI bikes don't appear to offer any advantages over the carburated versions. The Montesa has a ridiculously high idle, which would stop me buying the bike, and the Ossa certainly from what I have seen doesn't start any easier, make any more power and most people seem to get them remapped? At the World round we went to two years ago we arrived at the practice area on the Thursday as the first riders started to practice. All the two stroke bikes were ridden untouched by minders or mechanics [Raga changed a clutch] however the hondas of Bou and Fuji were continually hooked up to a laptop, sent off to ride for a couple of minutes and back to the laptop and technicians again. This went on for some period of time, meantime all the carburated two strokes,GasGas ,Beta, Sherco, performed without incident. I did not see the Ossa of Oliveras at this session so cant comment on his bike.
  10. You have answered your own question here. If you buy a 300 gasgas and put a low compression head and a flywheel weight, you get the best of both worlds - plenty of torque plus plenty of top end. I rode a standard 250 the other day hopped back on my 300 and for me there is no comparison, I have more options on the 300, I could ride the section in a higher gear than the 250 or stay in first and use the extra torque to find traction, I love it.I really could only use one gear and technique to clean the section on the 250. The bottom line is the better the rider the better the clutch work in particular, and the more power you can handle. Trials riding these days requires you to use the clutch to find grip as the throttle becomes less important than it was.
  11. I have a 2014 racing with a reiger and the latest linkages and it is the best rear end of any of the gassers I have owned. Mate has one with a standard ohlins and in my opinion the reiger is much better. I am pretty sure the linkages can be upgraded, check with the US importer.

    Definitely replace the condensor, cheap and easy to do- a faulty one can give a nice healthy looking spark when cranking the engine over yet cause problems when the engine actually runs.
  13. sherpa325 replied to sadlotus's topic in Bultaco
    First of all make sure the points are clean, the smallest amount of grease or oil will stop them working. The best way to ensure they are clean is to pull a clean piece of paper though them after you have let them close up on the paper. A while ago I had a similar problem and it turned out to be the tapped hole on the points where the wires attach was not fully tapped through. So when I tightened it up it bottomed in the hole leaving the wires ever so slightly loose causing no end of problems. Cheers Greg
  14. sherpa325 replied to jrsunt's topic in Montesa
    I think the technical term is wrinkling and is normally associated with sheet metal failure. As copemech suggested I would grind the area until smooth and fill with weld as there appears to be plenty of room to add a reinforcing weld Cheers Greg

    If you have read all of the fantastic interviews that gasgas249uk has put up, it is pretty obvious that we are very lucky to have a core group of Spanish and to a lesser extent Italian enthusiasts who are willing to produce Trials Bikes for us to buy. Without them I doubt we would have a sport at all. They continually put their money and expertise into producing some fantastic bikes that are cutting edge in design.They have been doing this since the seventies. What we can buy from these European companies is pretty much what the top guys rode in the World Championship the previous year, I don't know of too many other sports where this happens. The bikes are lighter and the power delivery gets better and better as does the whole package. On the flip side I cant begin to get my head around how you can produce such a quality product in such limited numbers. How much bargaining power do you have when only ordering two thousand custom made ignition systems, or rear shocks, or forks, or shafts and gears for the gearboxes.I would imagine its very difficult to keep a reasonable price on the components and also provide the service that is expected with such a small production run. These are not large multi national companies with infinite resources [they are not interested in our sport] they are small companies chasing a dream with very little chance of achieving a decent financial return. I just hope they keep on doing it, all of them. PS If I had to go back to a TY mono motor I am pretty sure I wouldn't ride, definitely the worst performing trials motor I ever owned Cheers Greg
  16. sherpa325 replied to heffergm's topic in Gas Gas
    But are they low tech, heavy and reliable
  17. sherpa325 replied to heffergm's topic in Gas Gas
    I wouldn't hesitate to buy a gasgas. They are fantastic to ride and I personally have had zero problems with them. I have owned five Pro's and three of the earlier TXT series and the current bike [2014 300 Racing] is the best bike I have owned. The gasgas clutch and its large engagement range make it easier to slip than other brands, the Reiger shock transforms the rearend and the power and its delivery is more than you could ask for. You can also quite cheaply tailor the power to what you prefer/want by adding the flywheel weight and cylinder head inserts.I love the light weight and as I get older its less tiring on the body than anything else I have ridden, I also have four Bultacos. Cheers Greg

    I am not sure where any of this information came from as Sammy Miller was out here in about 1970, and don't think I have heard of anyone who has bored a 250 out to 350 and by 1974 I am pretty sure he would have been riding the TL Honda.

    I wasn't going to post this, but it finally got the better of me. The bike is a M151 1974/1975
  20. I cant recall the last time I saw one of those brackets. I had both M92's series 1 & 2 -had the best time ever with the series 1 as it was the first 'good' bike I owned, also the first bike I competed on and the first bike I got a trophy on. Basically the bike I learn t to ride on and the bike that got me hooked on trials and Bultacos. Unfortunately I don't have to many photos of my old bikes, that's it in the background behind my then girlfriends Lobito
  21. I would imagine that is a very rare bracket, my original one back in 1972 only lasted a couple of months from new, before cracking just above the fork mounts. I replaced mine with the vertical style Sammy Miller ones- oh the memories!
  22. sherpa325 replied to mjc477's topic in Bultaco
    The swinging arms were lengthened on the M182/183[1976] by about 10mm. I am pretty confident all the swinging arms from that point on are all the same length. The Comerford bikes could have longer units as some of them had the S/arm pivot moved closer to the engine which would mean a longer arm to keep the same wheelbase. The longer swinging arms have a rectangular bottom shock mount with an additional hole for pillion pegs, whereas the earlier ones have a smaller triangular mount without the extra footpeg mounting holes. PS I think the information on this forum is very honest and put on with the best of intentions, just maybe some people have varying degrees of mechanical & product knowledge. The thing about any restoration on a Bultaco is that the more you can do yourself the cheaper it will be and I personally feel the greater the satisfaction, and keep in mind they are easy to work on and that pretty much everything is available for them. Cheers Greg
  23. There is a diagram in this post showing the two brackets that hold the airbox in place Cheers Greg http://www.trialscentral.com/forums/topic/44249-air-box/?hl=airbox#entry323155
  24. Not sure whether you are talking about the steering or the fork action itself. For me personally getting off my 300 gasser onto one of my Bultacos, the steering and fork action are the least of the differences I find hard to adjust to. I find the slow response of the brakes, clutch and engine and the added weight more of an issue. The overall handling I find to be very stable and predictable, with the bike less likely to be deflected 'off line' like the newer lighter bikes. Cheers Greg
  25. Your triple clamps look correct for the 190. With the 325 bikes the lower triple clamp has a larger more pronounced arch which drops the clamping part further down the leg which means that the knurling on a 325 leg wont line up with your 250 clamps. I would think the easiest way out is to find a complete 325 front end [triple clamps included ,at least the bottom one anyway] and fit that to your bike, however this is going to alter the geometry as the front wheel will be pushed down and forward due to the extra length of the leg. I guess it just depends on what you intend to do with the bike. Cheers Greg
