Tr1AL

2012 made in march 2012 frame number 307 of bikes made that year. Go to www.teknikmotorsport.com for some limited technical info specific to your model

I know what you mean it does seem like it would be weakened by being like that but it works fine, I never saw a problem on one caused by the gap as long as the bushings and spindle are good.

As long as you have the large pressed steel washers sitting in the rear swing arm spindle hole of the engine casings then the gaps between the outer swing arm pivot points and the frame do not matter as the engine casings as one unit keep the swing arm centered., the steel washers protect the casing edges from wear obviously.

@on it I think you may have the answer with a TR2 type course as all the current top riders would retire and the overall skill level would be lowered for some time into the future.

@faussy hi there , regarding the funding bit I was only thinking of the TR1 group and the British Championship entries that on it spoke of., TR2 and 125 riders are riding a less challenging course and so that probably explains why it has a more healthy level of support the same as at club level where the main support comes from the middle and starter routes.

in my opinion if you have dwindling numbers at the top level then for the governing body to do nothing would be strange , they cannot change the bikes or the tyres as at present all manufacturers of those have invested too much to risk change in the current economic climate. No stop as it is now to me is a joke as the riders stop and go backwards about 10 times a section yet are awarded cleans. if riders have been expected to ride stop allowed type sections under no stop allowed rules as they had been doing for years using flick turns and hopping on the back wheel etc then it will take riders 5 mins to learn to reverse well etc and i personally think that will help riders across the board to have a better chance of success. To keep it as it has been is killing the sport so allowing the riders more thinking time in a section and allowing them to get out of trouble can only be a good thing from my point of view, as long as there is a suitable time limit for a section then i cannot see how it could damage top level trials anymore than it has already been damaged by the evolution ot the sport that has naturally occurred via Eddy Lejeune , bicycle trials and Jordi Tarres bringing trick riding techniques with them. The biggest cause of decline in numbers at the top of the sport is probably all the riding around on the back wheel that is done which only a handful of riders can do to the level necessary to compete at a high level. The only problem is it has arrived , how could it be banned or incur a penalty for using it as a technique Trial at the top level is dying because there are not enough riders that can find the funds to allow them to travel around Europe and just concentrate on riding their bikes I guess the 6 riders in the UK and the 5 at the top in the WTC have the time and money that allow them that luxury. Perhaps it is just lack of sufficient money that is killing Trials not the rules and regulations.

@EddieStiffback I remember when they were on sale ,The only advice that I would give is throw it away and buy a common and currently available Grimeca or Braktec front brake calliper with parts fairly easily available from many shops .In the time you have taken faffing around with that collectors item buying a Torx key that fits ETC and found the piston size you could be sorted and riding around. That is probably not what you wanted to hear. Alternatively buy a Torx type key very expensive for minimal useage make or find something that will undo the plugs and extract the pistons can be a hassle if you have not got a well equipped workshop then buy/use a vernier caliper to measure the pistons and see if the servicing kits that Braktec ,Brembo Nissin ETC ETC sell are compatible with your caliper block.

@trapezeartist Have you seen this , and of course just in balance to a geared E- Trial Bike for anyone that is interested. https://youtu.be/maZcbqIWYzY?feature=shared

People talk of restricting tyre width or harder compounds to stop the top riders needing dangerous sections to test them , an 80cc maximum capacity could open up the competition to lesser mortals. It would be amazing to see what happened if that rule was brought in.

Hello your bike going off that Frame number is a 125cc 2013 model built in September 2012 number 6,147 of bikes produced by the factory that year. A frame can be changed for a second hand one if the original is damaged so may not give a definitive answer to the origins of the bike.

Is he the site owner ?, who runs the site?. A question and answer forum for bike maintenance is a great thing to have I am definitely not knocking the site and its essential if you have a classic/twin shock bike as all those years of experience from the older members are invaluable if newcomers to that particular branch of the sport are to thrive , feetupfun seems to be one of those mines of information. like the chap at thehellteam is for more modern bikes. Have a good evening.

It is just a nod to my late 'News Flash' about Raga faussy as a poor joke , if you go to rider news on Trials central the news is Fajardo banned for a year and Busto signs for Vertigo both current news of course , the news should actually be Matrtin Lampkin signs to ride a Bultaco under current UK standards.

If you did not know yet Busto has signed to ride for VERTIGO.

Yes but this is a UK Trials site , after Covid and Brexit combined we went back in time to the 1970's , and that unfortunately is not a joke you should see what passes as entertainment on the' idiot lantern' at present , there are literally programmes on most channels that were screened in the 70's and so comms is along way behind so sorry about the delay. If it was not for 'trialworld.es' and 'todotrial' we would not know anything.The only thing on this site seems to be Questions and answers. As it is Trials Central I would have thought it would have more News to keep people in the loop. Enjoy your day.

I would say that beating Bou in any situation is a very big deal but especially being a rider that comes from the UK as there is very little support for Trial riders here its a secret sport. where as in Spain it is a well known sport and their governing body helps nurture new talent for the WTC.

If you do not know yet then Raga has signed to ride a SHERCO.

@lerk I think faussy is talking about the knocking not the bent flange , something is not right with the flange plate it should fit almost flush with the cylinder with a small even spaced gap of about 1mm , try taking off the crush gasket/gaskets ? there should be one perhaps someone fitted one thinking there was no gasket there and you have 2X gaskets in there . They are crush gaskets and so they come out quite easily get a long thin screwdriver with a flat blade about 5mm wide put something on the edge you are levering on like a cut piece of hose pipe or whatever to protect the cylinder and gouge the end of the screwdriver into the inner face of the crush gasket and lever it out then make sure there is not another one in there before thoroughly scraping out the recessed area and putting a new gasket back in there. As far as knocking/ pinking goes you need the highest octane petrol / gas you can buy at the pump 98/99 RON and you can try fitting a 1mm thick aluminium spacer available from www.trialendurodirect.com approx £25 at the head to lower your bikes compression slightly or fit a GasGas/S3 low compression head insert. Lowering the compression will obviously soften the power output of the bike which is not a bad thing if you ride in wet conditions.

@lerk When you fit the front pipe/header into the mid box put some silicone grease on the 2X orange silicone rings and on the pipe so that the pipe can move around easily and when you fit the front/header pipe to the cylinder DO NOT have the Mid box mounting bolts tightened have them as loose as possible so that you can get the front pipe to enter the crush gasket and sit correctly then tighten the flange plate just enough to hold everything square the front pipe should be able to swivel at the joint , now tighten up the mid box support bracket bolts and then swivel the front/header into the best position to be close to the bike and leaving an even gap at the join where it enters the mid box and then tighten the 2X bolts at the flange plate.

@lerk If it bothers you take it off and flatten the flange plate again and this time do not over tighten it , if you overtighten joints you are more likely to have leaks because you are distorting things , Most of the time torque settings tables from the manufacturer and torque wrenches can help to avoid this.

Rear Shock rose joint/ spherical bearing in the shock eyes of a GasGas JT model is normally a GE12PW size ID = 12mm OD = 26mm W = 16mm .

There may be problems this year at ACU events , the organisers will become suspicious when Paul Melhuish wins all the classes at their next event and is also every competitor in the event..
