  1. They look like they are just too short, and forcing them to fit wont be a good idea - could break when fitting, or worse still could break later when running I would try and get some different ones personally
  2. If you think ethanol could be a problem , there are options you can take to reduce the chance of problems Fill your tank on the day that you are using the bike, then drain tank & carb after you finish riding { ethanol damage is usually a slow process, not instant } As already mentioned - Use ethanol free fuel - not always easy to find + sometimes expensive Remove the ethanol from your fuel - I have never done this , but there were a couple of places selling kits to do this - Ethanil.co.uk, I think was one company that sold a kit for this purpose . { i have no idea how successful this is , but the kit wasnt that expensive }
  3. Does that not already happen every summer when the French ports go on strike ? 🙂 I have never ridden a trial in Kent , will have to see if I can get to one in 2021
  4. Some DT100 twinshock , clutch cover may fit ? Flywheel side , if you are using standard flywheel then only TY will fit over it believe ? if running smaller flywheel then maybe a DT cover ? and the TY125 of course , but I think this is a euro only model { Disclaimer - its years since I had one and played around with different covers , I could be wrong on some or all of this }
  5. No, I don't think prices of bikes & spares will increase anymore than they would in previous years every year prices increase due to - inflation , raw material costs , wage rises , currency exchange rates etc. etc. cancelling Brexit would not change any of these things Covid may have an impact on prices
  6. I cant see Brexit having any effect on any Trials anywhere in the UK I can see Covid effecting trials during 2021 , but that will depend on if it gets worse or better As for a massive financial crisis , its possible , but you wouldn't think so if you saw all my Neighbours - most seem to being having a house extension built or new kitchen / bathroom { never seen so many skips in the road }
  7. Yes, I think your right, at least for the early part of the year but even that depends on things getting better not worse

    Ossa MAR engine hole ???

    Yes, got the same hole on my MAR
  9. The middle part looks the same as my own MAR, the silencer - I cant remember ever seeing one like that on an Ossa the front pipe could be TR77 { they are that shape - MAR is much shorter }
  10. 2K would be better than a can, but you may get good results with a can on something as small as a caliper High temp paint may be needed on a road bike, but would a trials brake get hot enough to need it ? as for brake fluid , I think some of the modern fluids are glycol based , which is not so harmful to paintwork as the older fluids were
  11. Mikuni, Dellorto, OKO , in fact probably anything would last longer than an Amal If possible buy from someone who can advise regarding size & jetting etc.
  12. I have used 4mm mild steel to lower the foot pegs on my Ossa with no twisting so far after a few years as for welding or Bolt on - if the Chrome on the frame is good , it would be a shame to burn it off where you weld on your plates , so maybe try bolts first ?
  13. have you tried putting them in a dishwasher at the highest setting ? { not recommended if married } like everything else sometimes you can get good results this way, sometimes not

    OKO Carburetors

    Yes, isn't the OKO a good copy of a Keihin ? and some of the other copies are not so good
  15. I could be wrong, but I don't think you can compare jet numbers, from one carb manufacturer to another . I know that Mikuni Hexagon head jets & slotted head jet numbers are not equivalent - one is flow rate I think ? , the other type some measurement of the physical size ? also with some jets the flow is measured in the direction fuel would flow in use, while other jets the measurement is done in the opposite direction you would be best to call a carb specialist
