  1. Wow ... well to be honest: YOU are showing of a video whilst riding the quietest modern trials 4 stroke bike available so quite that you can ride through a flock of aries without disturbing them, see here: But yours seems to be obviously louder and then asking how to get the bike quiter (again). And then where your live, the forum is based in Britain and so are most members, the UK is a country that "invented" the English Garden there are as I know only Danes more picky then the British about gardening. And You are showing us grounds/properties with rumped tree and vegetation less, with plasticfoil like fences and gas containers in the main entrance. (even me - as a German!- is appalled at the desolation). Then your other "equipment", here the kind of helmet of course you can do whatever you want, but firstly it's not imitative and second it is not legal. So much consideration could have paid to the other members of these forum to wear at least a real helmet? So all in all your threat opening question gave the audience here a lot room for ironic answers, and in Britain are living the masters of ironic humor that is your problem, as how you shout in the forest the answer will be. In my opinion you should wear better protection and the Honda-Montesa 4RT is in loudness a downgrade the bike will never be as quite as the Beta.
  2. Damm, I forgot how good Leslie Nielsen is. Great stuff!
  3. That reed used as a "breather" must be mounted to the crank case and any build up pressure will be released by the reeds out.
  4. I like the idea. But: The bike has main compounds of todays make mounted so can't be used in our (in DE) classes in either twinshock nor aircooled mono as the engine is litterary brand new. And as longer I think about it as more I feel very comfortabel about our rule. Why hasn't the builder used a Dax 90 engine or even better a Honda Cub engine of the right time period. You get them for little money everywhere. Then it would be no problem to use the bike im any twinshock class. The twinshock class is dedicated to classic and vintage motorcycles. Here the builder has made it for himself too easy and that to the cost of other riders still trying to keep their old engine running, (a complete engine less expensive then a top job for a Fantic 125 is a problem).
  5. Which kind of head steady you use is irrelevant. The standard OEM fork type head steady works great as long as you mount it as the last engine mount and when de- assembling take this part at first away. Second you don't want to put stress on the plate of the fork type head stead by bending it. You need to unthighten and loosing the nut and the bolt to the cylinderhead so it's possible to de- mount the headsteady with ease. To the sprockets I run 10/39 when I remember right? (have to look up)
  6. My personal two cent as also having something with wide spread knobbys in the shed... There are standard inner tubes and reinforced innertubes available. The reinforced are around 4mm in thickness and used mostly for Enduro riding and as these innertubes are too very heavy I don't see any advantage mounting these to a trials bike.
  7. Mmh first you need to take away all dirt. Thus is done the best and easiest way by using car wash shampoo and a smooth brush. Take a big bucket and wash there the tank with much hot water and shampoo. It's astonishing how much you get off. Then there might be some grease oil or others debris left where you need something differnent more a solvent like. Here I had good result with acetone on a fresh rag just applied to the cloth then once wiping form top to bottom. Never use used parts of the cloth twice. Then you will have a dull and partly even whitened gas tank. Now a short treatment with a heat gun with about 200 - 300 deg Celsius and the dull surface will melt up to a silk glosse surface. (All gas has to be drained in advance the drained gas tank should too be stored with cap removed for at least two days the opening should be facing down). Done ... it needs some skills especially the last step. But I don't know a better way to sort the rough surface of the plastic tanks. You might try out the handling of a heat gun before with an old scratched fender or likewise plastic. Any discoloring of the gas tank can't be removed.
  8. Very difficult. The Fantic is already a twinshock and a classic bike so here you have a bright future in terms of sale. The Beta just turned 30 now beeing aclassic bike but still no major classes and class mates ahead. No bright future in the short term sales wise. I think the Beta will rise significant in the long run (next 5 years or after 2020) if you can wait so long. Just now no one need this bike really. I too would keep both and as later you sell the Beta as more you will get. And yes ... I have a Beta TR34 too ...
  9. Hi The rear shocks mounted to my 242 are pretty mich toast aa The springs are too not the right ones I look for replacements. I think I habe figured oit which but I would like to know which is the best length in your experience. Sometimes slightly longer 10mm do provide better handling but sometimes not. Your opinions?
  10. Wasn't it stated in previous threads and posts? There are no pistons available and this sadly hasn't changed in the last three years beside one or two accidental findings at some dealers. Even frequently asking wount cure the problem? 250 - 300 GBP per piston of a run of 10 to 15! that are numbers. As previous mentioned it may be the case that your piston is still reuse able but the cylinder needs an overhaul, but too the opposite can be necessary (the normal case btw.) With a new plating of the cylinder often the con-rod and his bearings are at their end of their lifetime too then these should btw. also been replaced. Get these three main parts checked as with the reasonable amount of money to spent already for one of them it doesn't make sense in the longer run to just replace one instead all three as if one of them fail or got to the end of wear it will effect the others too. I personal had good experience with Woessner from coating (Nikasil), piston forged custom, con rod can be replicated by them too. (found a NOS in France). Woessner did the job very good and priceworthy btw. and you have a guarantee on the three main parts too.
  11. Very useful information about how to dail in and adjust the suspension to your trials bike which covers modern and twinshock bikes and too rear suspension (shocks) and front suspension (forks). Static and dynamic say and so on ... You can look up the complete article which was released in two parts in Trialsport Magazin No. 360 and No.361.
  12. Back in the days when shocks where nothing else than mechanic springs with some damping far away of being progressive you could archive some progressive reaction when they where mounted with lower angle That's why Ossa did it with their Gripper model and these (not very long lasting) Telesco shocks. Luckily these times where over and progressive springs are no available.
  13. At first you need the right springs that matches the bike weight and your weight with gear to your rear shocks and the fork. You can determine the right springs if these deliver the right sag for trials riding static and dynamic. static = standing bike without weight of the rider, dynamic = standing bike with the weight of the rider while standing on the bike (with full gear). If so everything is OK and any personal adjustments then can be made by changing compression, rebound or damping. The main effort is to get the right springs according to your and the bikes weight
  14. In my personal view it's up to the photo the knowledge about a bike or a rider is irrelevant when you look at a photo all what matters is the shot or capture. The right moment of movement or calmness the failure or the win how all is situated where on the photo, that is the spice in photography that's why photography still matters.
  15. Yes You are right, it's the monochoque and with front disc brake fitted 304. Good eye's. The 304 is nice too and I rode one in 1986 very similar to the 242 beside the better front brake and the rear shock setup. I has my best results in trials on 1986 ... To the red 242 the model was even sold in two color schemes with white gas tank and with red gas tank. The red one wasn't sold very much but "survived" for the 304. PS: I just acquired a 242 in super nice state and original a 1984 MKII model. I too fitted it with the red gas tank and seat combo I found abroad as I like that look so much more and the gas tank is made out of PE so no cracks or leaks or difficulties with our gasoline for future riding.
