  1. Not my finest moment lol, that fall made a right mess of my leg on the 4th sub on the first group, didn't want to give up tho, it was worth it in the end, saw some amazing places and got to ride with some really great people, will definitely try to go again my leg a week on Blackwater Dam
  2. Another quick update the Greeves is running great. It got me round the pre65 Scottish may not have been very stylish but I got round , my hat goes off to the 6 days riders as I'm done after 2
  3. There was no signs of any piston to head contact, but it must have been close as when the barrel was torqued down the piston was above the top of the barrel, it was the only thing I didn't check when I originally built the engine ?, it would knock mainly under heavy load pulling up steep hills, on the flat it would be fine, the timing had been checked multiple times and I'd tried different settings all made some difference (good and bad) but non cured the fault this is the only change that has stopped the knocking, so weather it be squish or compression im not sure but it runs great now, it would be nice to get an expert go through it and find out exactly how it should be set up or how close ive got it, as TRF says there are many different combinations of these engines so it may have been a bit of a lash up in the past lol
  4. Yeah im just glad that ive got it to stop sounding like a bag of spanners and possibly ruining a rebuild, it runs great and has more than enough power for me
  5. Every day is a school day like I said I've done basic rebuilds before and never had to mess with any engine like I've had to with this one, it was a non runner when I got it and it's been a pain in the backside
  6. I've never messed around with the squish on any of my enduro bikes, i used to get a local kart engine builder to do any major work for me as they would fly once he had finished with them so I wouldn't know what would be the best clearance
  7. There It was quite a lengthy process trying lots of things one at a time, it got to a point where nothing i did changed how it ran for the better, it would knock/pink under load but once you were on the flat it would rip your arms off once it got going, I didn't measure the squish but took off the head and tightened back down the barrel (head bolts hold the barrel aswell) and the piston was sitting above the top of the cylinder so I took a punt on using an old head gasket that my uncle had which was the correct bore and was I think .9mm thick and it has totally transformed how it runs. Thanks that pic was taken last week on a trail by Hawks Nest
  8. Just thought I'd update this post I've finally sorted the running problems. First fault (starting/reving)was the brand new carb which has been swapped for a new amal premier carb, the second fault was a combination of things (gettin hot/pinking), turns out these Villiers engines have a usefull feature of a drain plug in the crank cases, which had come loose on mine and was letting in a small amount of air making it run hot, so that got a new copper washer and some thread tape making it run a lot better but not perfect, whilst talking with a couple of riders whilst out practicing they mentioned about the squish with it having a rebuild, so that was checked and found to be very tight/narrow so I've used a copper head gasket I had off another bike and what a transformation the bike is a complete different animal, so thanks to those who posted ideas and maybe this might help others in the future because there's nothing worse than a thread with no update on whether a fault has been fixed, here's a pic of it now it's finished
  9. Same here on my Greeves running a brand new electronic ignition, it would do 2 laps of a trial then pack up, swop to a new one (ngk) and would do the same, swoped to a platinum one and it's been fine since
  10. Brill footage, just went all wrong once you pointed the camera at me lol
  11. Happy to help, good luck with the rest of your rebuild
  12. Ive always used one of these aswell, never had a problem
  13. That's a woodruff key you need to take that off the crank, tap down on the end closest to the gear and the other end should pop up then use a drift to knock it out of its hole, thay can be really tight in there, I always repace these as they can sheer, usually when you are furthest away from your transport home.
  14. I know the very early ones were TM powered so may have been developed from these power plants around 95/96
