  1. If you have the inlet the remaining stuff sculpturing a foamfilter is easy. I can sent you template shaped forms of which you can sculp and assemble your own filter.
  2. A cable clamp made out of aluminium or stainless steel is used one fastener is mounted to the screw of the rear light, the other with the fastener of the rear fender to the frame.

    Spoke angles

    I would check the fit of the spokes in the hub. In this case the bearing surface of the offset spoke to the hole in the hub. If the spoke is not in position, bending it back to the required angle may help However, spokes are made of high-strength steel, the nipple has been cold-formed, so re-forming in the same place is hardly possible and would further weaken the strength of the spoke at the weakest point. If it's just for standing down, it's OK, even light driving is fine, but emergency braking or a drop off could cause it to break. When spokes start to break it's a domino effect... Because of bad experience I don't try save on spokes and nipples.
  4. Ethanol is not stable and wil oxidate with oxygen to acetic acid (Essigsäure). Acetic acid is corrosive against most metals like iron (steel), aluminium and even brass. When you ride the fuel inside the tank is pushed around inside the tank and thus gets contaminated with oxygen which comes through the vent hole. Looks like that:
  5. My biggest concern is storability, I do have times when I do not ride the bikes but gasoline mixed with oil left. E10 oil mix got kind of stained especially when stored in winter time, thus I too only use ARAL Ultimate 102 octane ethanol free. The BP Ultimate should be of the same recipy, ARAL and BP are using ether instead of ethanol in their fuel, that is too the reason that fuel does clean up the engine a bit inside.
  6. Yep, but I have figured out with experience and the years it takes a long time until the oil is warmed up and under cold weather conditions it is really thick which can make shifting harder. I now have changed to ELF HTX 740 to all my bikes, from SWM TL NW, Montesa 242, Panda TC 220, Beta TR 34, Yamaha TY and the Bultaco Sherpa to use just that oil to clutch and gearbox.

    Sad story

    Very sad story ... and all the effort you have put in ... could you do an arragement depending the effort and diffrenet status of the bike with the owner?
  8. I personal would use the gear oil to the gearbox and ATF for the primary drive and clutch. The ATF is more versatile then gear box oil so a good choice for chain and clutch. Or as already stated Elf HTX 740 for both drives.
  9. I take the chain off for cleaning, then clean it with a brush and an old rag bit after that treatment most dirt from the outside is gone. Now the chain goes into an old kettle with aceton here I "stir" the chain in the solvent for a while, after that treatment the chain is also clean at the inside and free of fine debris. Last treatment is hangig up the chain and use some brake cleaner spray let overflow rinse down the chain into the previous mentioned old kettle and last not least give the chain a rub with an old towel. Then I apply PTFE or dry lube to the chain, then put it on again, that has worked so far very well for me. The chains had very little wear, the chain stays too much cleaner and is super easy to clean too.
  10. Did all went as expected or did you found any special issues? As I have a 312 too I'am curious about how the build went on?
  11. Yep to any meanical driving gear should be a felt ring soaked with an oel grease mixture btw. The drive to the Sherpa and Alpina is located at the rear not the front to my personal knowledge. Then the gear consist of a hyperboloid gears so it is impossible to tell you the geraing. These rear drive speedometer drives are sadly very rare. I am frequenlty looking for speedo gears front especially but too look at rear ones. I only found one used speedo gear in good shape in the last ten years wich I now have as a spare to myy 199b so far...!!!

    2x2 SWM TL320

    Cool to get now information of first hand. recently there was another trialsbike with the frontwheel drive around, this time a Fantic 240 and obvious with the a drive that must have been manufactured by your father. See in this video and the following sequeces from the D-Cup Trial in Augsburg, 01.10.2022: YouTube Video D-Cup Augsburg 01.10.2022 - 03:05 - 03:55, - 05:45 - 06:16 - 16:10 - 17:25 (the best capture I think). Are their still 2 wheel drive set up's left? How many have been build?
  13. You find good Interest groups on Facebook for that purpose, as I have a 242, why I am in the 242 group which indeed has a lot of information depending that model. But isn't this forum and especially this department all about Montesa bikes too? Thus I would like to have all information here and if I can would contribute to this Forum if in need first. So what information do you need?
  14. The Japanese bikes are easiest to work on and of highest build quality, at least Yamaha and Honda. Four strokes have more engine parts and are expensive IF there is a problem. Then the Italian bikes where SWM with it's Austrian Rotax engine stands out in build quality, then Fantic then the other brands. The Spanish bikes are good some very good like the Montesa 242 but in terms of reliability third.
  15. I have a well used original front light lamp mask combo if in need? Details PM.
