  1. Possibly other Yamaha reed blocks / rubber inlet manifolds from the DT, RD ranges could have been fitted as a perceived upgrade, or just because of availability ?
  2. I am glad to see that you have found some aerosol products that actually do what they claim, as in my own experience any aerosol heat resistant paint has never been very petrol resistant , or even water resistant. I shall give these products a try on my next exhaust refurb. I have previously only found - Powder Coating, ceramic coating & 2 pack paint to be the only products petrol resistant { and some of these are not very heat resistant } thanks for the info
  3. I once purchased a non-running 2 stroke bike at a cheap price. The only fault was the piston had been fitted the wrong way round. ( That was the only lucky purchase I have had, most non-runnners I have got involved in have been much worse than expected )
  4. Okay, so how would an electric bike do in the International Six Day Enduro ? ( I suppose you could ask for a rule change - permission for much longer stops for the hours needed for recharging compared to minutes to refuel, that sort of thing or perhaps change batteries , but decent batteries cost £thousands compared to a petrol can + some fuel at say £20 ) As I mentioned , the very expensive, cutting edge electric prototypes only do one lap at the Isle of Man, ( presumably to avoid overheating / flat battery etc. ) No thanks , I haven't seen an electric bike yet that i would want to own
  5. Sounds like its not really suitable for Enduro, Average speed will be higher than trials, plus distance traveled would normally be longer as well I would have thought. I know I am old fashioned, but electric bikes still have a lot more work needed to be better than a petrol bike I think even the electric race at the Isle of Man TT is still only 1 lap, and those bikes have had a fortune spent on them The trick is to cool the electrics without using any battery power as that will just shorten the range- if you can invent something Tesla will give you millions good luck
  6. Thank you for thinking of the non facebook users ( yes , there are millions of us who haven't been brainwashed into believing facebook is the only possible way to communicate)

    Shocked

    Yes . I do know the secondary voltage on my 2 stroke , but I am sure the ignition hasn't enough power to do welding. ( which has been quoted for the electric bike concerned in this post ) Thanks, I will take my chances with the kill button

    Shocked

    Wow , I think I will be sticking with 2 stroke power , all this talk of - 50+volts , 800A fuses, mixed with heavy rain , is not convincing me that electric is the future. Good luck, I hope its a simple fix
  9. Never been interested in Pre65 trials, because 90% of people involved seem to love moaning about what other people are doing and taking everything too seriously. I do think it would be better if the bikes at least looked like an old bike - tank shape , seat, frame , colours etc. instead of looking like a modern bike with an old engine fitted, but thats just my opinion as an outsider and its now too late to expect the riders who have spent £thousands to change their machines I ride a tatty Ossa in non serious trials , where many people have better machines than me, but I just enjoy my own riding and dont moan about what other people have got. If someone is rich and wants to spend £1000+ on a pair of forks , then good luck to them. there is a place for everyone , most trials have an easy route that any original bike could get round , you dont have to keep up with the Jones , enjoy doing your own thing. I do think its a fallacy that there are thousands of Original Bikes in sheds with owners who are just waiting for events catering for Original Bikes , there may be a few but the majority of these bikes are either Family Heirlooms , or they are being hoarded as an investment
  10. I seem to remember someone fitting an OKO carb to an RL250 , but cant remember if it was on here or another forum. As it was an RL250 not a beamish , it may have been someone in the USA or Aus , NZ etc. ? A job for Google perhaps ? Failing that you could try your Cota carb on the Beamish as it is and see if it works okay, { they are both 250cc piston port 2 strokes , so similar engines } - if okay then use the same jetting / settings as a starting point and fine tune later

    Kick start

    Cheap options would be - lowering compression as mentioned , OR - How about fabricating a longer kick start lever , for more leverage ?
  12. Partly Covid etc. Partly the dreaded facebook , God knows why people think facebook is easier to access - its no easier to access than any website or forum I find the layout of facebook is crap, any useful info buried in people trying to sell rubbish Anyway, this is a good site, long may it continue

    Pre-mix Ratios

    40/1 with a decent modern oil should be okay for trials, if doing any road riding then maybe more oil would be a good idea. I have run my Ossa MAR on this ratio with synthetic oil for years with no problems ( may have just been lucky ) personally wouldn't go any leaner than this, as I think too much oil cannot do as much harm as too little oil could do
  14. sounds like an air leak somewhere crank seals / gaskets etc. what carb have you got fitted ? have you recently worked on the bike before this happened ?
  15. There is this tank on ebay at moment is it the same ?
