  1. Thanks for that. I’ll look to go for the 2nd gear mod then Looking at the gearbox I have here, It looks like I’ll have to remove the small ‘end gear’ which looks like it’s pressed on to get to the new pinion. Any idea how I can do this? Is there a special tool or will I need to make one? It’s currenty 17t so will need changing anyway. Also it’s been a while since I’ve had a Cub engine apart. Is it possible to remove the sprocket attached to the sleeved high gear and take the gearbox out or is it a complete crankcases apart job? I ask as the gearbox in the engine, which my late father built, has a std gearbox fitted thanks
  2. It’s about time I started again on the Cub prep. I’d appreciate your opinions on the following 2nd gear 26/19 - is it worth the effort and expense? PVL or HPI - the only experience I’ve had with PVLs is to understand they are pretty basic with little advance. thanks in anticipation
  3. I'm about to start doing my cub engine and will opt for an electronic ignition. Does anyone know where I can get the pillars welded for a PVL or HPI? While I'm at it, the bike was my old mans and he was going to do the window mod to access the drive sprocket. I believe Ray Small did this mod. If he still operating?
  4. The trial last weekend was my first. I was made to feel most welcome, good bunch of lads and a fantastic venue. I've lived in Somerset for nearly 50 years and didn't realise that this place existed. A good selection of bikes and good routes. Suffice to say I'll be doing another one with the club next weekend.
  5. I have taken Spens advice and Steve Panter sorted me out with a new carb. The result, the bike is a lot easier to start with a choke and runs a little better. However on checking the plugs after a trial I found it was running way to lean, so raised the needles a little to the last slot and that seems to improve things. A new main is on its way. However I still struggle with bogging coming off tickover onto the needle. The carb is fitted with an O-2 needle jet and 5C23 needle. I'm not good with jetting in this area so has anyone changed this part if the circuit. In summary when I snap the throttle open it just doesn't pick up. I can't decide if it's too weak, not enough fuel, or too rich, too much fuel. Any help appreciated as I have a trial next weekend I'd like to attend . Thanks
  6. I went for a first ride on my restored Ossa MAR today and experienced a few issues I have put down to carb. The AMAl is the original from 1973 so I figure it has probably seen better days. All I know is that despite new jets and refurb kit the bike has no zip making climbing banks almost impossible. I'm thinking therefore of changing carbs to a Mikuni. I appreciate that this one has been done to death but...The general concensus seems to be a 150 main and 35 pilot on a VM26 Mikuni but this is only part of the story. The Needle and Jet needle are very important also. The standard VM26 comes with a O-0 needle Jet and a 4J13 Jet needle. For those who have fitted a VM26 to an Ossa Mar, did you need to play around or change these jets?
  7. I'm thinking this one might be a better bet
  8. I'm looking for a sump guard for my Cub. I've seen this snazzy looking thing from Sammy Miller...er made of plastic. Can I ask whether anyone has fitted one of these and if they are robust. I'm guessing the alternative is the steel one from Meridan offroad
  9. I thought I'd let you know how this one ended up. To to begin with the original silencer appeared to be touching the tyre. See below. So I purchased some 38mm mild steel pipe from eBay and welded up an angle. This slipped nicely over the original pipe with a little Dremel work on the inside of the tube. I also invested in a £12 pit bike silencer just to see what it was like. It turned up and didn't look half bad. The bore was also 38mm so an easy fit. I then made a small bracket using a bit of strip from the 2 mudguard mounts to the can strap also provided with the can. Having run the bike insilenced and with the new can there is a big difference which I think will be acceptable
  10. Thanks Lotus. This diagram is very useful however it shows the spare wires other than the coil are red, white and green. I have red, brown, green/white. Puzzled
  11. Hello. Can someone be kind enough to let me know what the wiring arrangement is on an OSSA MAR Motoplat. Here is what I have. Blue / Black - go to the coil. Any idea what the following do; Red / Brown / Green & White. im looking for 6v DC to drive a horn or a supply I can regulate. thanks.
  12. Here is a picture of the cub from some time back. He started a thread on the Cubsite forum which on revisiting is an interesting read. http://www.cubsite.com/cubforum/viewthread.php?tid=1925&page=1
  13. I've inherited a Tiger Cub from my late father. The old boy bought it way back in the 70s as a trialer and intended to finish it off. He died nearly 40 years later having nearly finished it and now it's time for me to spend the next 40 years carrying his legacy forward. My thinking here is that it MUST be finished as he would turn in his grave if it got put onto eBay. So here is what we have. 21" front wheel, Triumph Mountain Cub forks and yolks, points in the side engine with electronic ignition, Ray Small wider swinging arm, a load of standard bits, a good trials tank and tinwear. Sorry for the preamble and onto my question. How strict are they on eligibility? I want to keep the Heavyweight forks but will convert them using some stuff I can adapt. The plan would involve drilling a hole on top of the big fork crown nuts and inserting a stainless steel dome head screw on top. Would some rivet counting scrutiniser type call me up for it? Thats all for now but I'm sure I'll be back with a few more questions over the next month or so, e,g, footrest position, how to make a bash plate, gearbox ratios, etc..
  14. Thanks all. Conclusion then is that the WES option needs a bit of fiddling and the other most likely is that the pips is bent. The end of the mid section does seem to come out fairly straight and square which is why I thought it was a silencer issue. Ok so mudguard and seat off for a ponder.
  15. Hi there. The rear tyre on my OSSA MAR is a 4" Michelin and it fouls the exhaust can. Can anyone advise whether the WES silencers are 'stepped out' and would provide some more clearance or whether I'll need to make something. Ideas please folks. Thanks
  16. Hi there. I do a lot of different riding including road racing, trials and pottering around on an old 1969 Triumph Tiger100. I've always used a full race on the road, but I'm trying to work out whether a trials helmet is rated for road use. I'm very rarely over 60mph on the Triumph, but when trailing I'd be surprised if I go over 6mph. What's the view here? How do they rate these trials helmets? Are they ok for road riding? Thanks
  17. Nice one Spen. I've got a tartan aerosol I bought off a bloke here. That should do the trick
  18. Hi. I have an OSSA MAR that I want to compete in local twinshock trials events. Can I ask whether the front number board needs to be any particular colour? I ask as on my road race bikes I have to use certain colour backgrounds; green for 250, blue for 350, yellow for 500, etc..thanks
  19. I've had a bit of a disaster this afternoon. Putting the finishing touches to my fresh OSSA MAR restoration and as I was adjusting the front brake cable the threaded post snapped off on one side. So can any wise folks tell me what other models used the same brake plate as I can't find anything on eBay. Thanks
  20. Thanks Woody. Picked one up and yes fits a treat. All back together now
  21. Can anyone advise where I could get one of the small nuts that secure the top headrace bearing on the OSSA Mar? From what I can see it looks like an M20x1mm or 25tpi. Thanks
  22. Is Dougie superstitious? Stopped work championship trials at 12 so is he likely to bail out of the SSDT after 2 more wins. If so I guess I'd better get upto Fort William soon so that I can witness for myself whethe he is...the most complete trials rider. Which I think he must be
  23. I've just spoken to the DVLA about my NOVA application and it couldn't be simpler. I submitted the VATNOVA1 form completing sections 1,2,3, 5, only and they have said that I will get a letter that I send to the DVLA along with my form V55/5 and an MOT certificate. With this you only need to complete questions 2,3,4,7,8,9,10,27, 31,32,33 which are very straightforward. You pay the registration fee that is £55 and the road tax due. Send a covering letter saying you want an age related plate and with any luck you should be good. They may want to inspect the vehicle. Hope this helps.
  24. I'm doing the same thing. Following the VMCC guidance, I called the HMRC on their helpline 03000 583020 and the bloke was really helpful. He sent me a form VATNOVA1 and following the guidance notes there isn't really much to fill in and many of the sections you leave blank. I haven't heard back yet but will report here once I have an update
