  1. I had the cush flywheel lightened hacksawd it then finished it on the lathe, love the extra zip and i dont think i lost much low down torque. I find i have to use every day multi grade oil in the clutch 20/50 Steve.
  2. This is my casing which has been strengthened and also you can see the chain casing protector. Stephen.
  3. Hi Dave just spotted this, my oko is a 28mm it was not far out as it came but i have got it on a 112 main jet and either a 52 or a 55 pilot and i bought a rubber carb pipe from a Sherco to go from the rear of carb to an angled piece of plastic 60mm? drain pipe tube then a Ram airfilter and i run the air box with no top or snorkel tube but have the rear mudguard well taped up. This sounds like a bit of a bodge but it works fine for me. Steve
  4. where are the cakes? episode two.
  5. I use a thin wedged screwdriver bit, tapped into the gap between the pinch bolts to open the yokes.
  6. I think i have found my answer, My auntie phoned today and she says my uncle had an Ariel red hunter when she met him and she is sure this was the bike.
  7. Doc46, I had to google shuttleworth snap, Made me smile. Steve.
  8. Up to now all i have is this photo, i wondered if could be a sidecar? Would you have clip on handlebars on a sidecar?? Also clip on racey bars on a small cc bike? so 350 or 500 is more what i would expect. My mum and me think i was about 3 or 4 years old and my uncle was 15 when i was born. I do remember looking at two old scooters under water proof sheets behind the garage (long since gone) so maybe he had one of those parked up next to his sports bike. Charlie, the car in the background was my dads Renault 4. One of my memories about my uncle Richard was i got oily hands from his bike and he washed my hands with this bright green slime in a jam jar and i have never forgotten the smell of swarfega.
  9. This is a photo of me on my uncle Richards bike,(1968 to 1970) can anyone have a guess as to what the machine was? We had my his funeral on tuesday 11th July 2017, he was a biker all his life, without him and my dad i don`t think i would be riding a motorbike today. Steve Bisby.
  10. I've had a mikuni on my Ossa gripper for years because i was after better pickup from low revs and the old Amal was badly worn. It has served me well but i was finding it would gas up on steep down hills and also flood the engine if i dropped the bike, so i have invested in a new OKO from scooter assasins which cost me just under £60.00 plus a couple of different jets and new air filter. It hasnt improoved the perfomance much but it has stopped the flooding... Bargin
  11. I once nipped up my majesty yamaha up in the scottish six days, riding along road section when it started to lose power then the next second the back wheel had locked up so i pulled the clutch in and stopped.after about 5 mins it fired up again and was ok. you could pull the exhaust off and shine a torch in to look at the bore and piston condition.
  12. This looks like Glen Scholey on a JCM.
  13. I agree with Dabber, number 23 is John Lampin, and number 26 is Simon Tyas. Not sure on the rest. Steve .
  14. Two other possibles to look out for are twisted swinging arm? and buckled wheel? Steve.
  15. My 1981 Ossa gripper has red stickers, yes they relate to the hardness but the harder ones are also heavier.
  16. I bought one about three weeks back from Splatshop at Chesterfield.
  17. I tighten the the clutch springs down just enough to be able to get a split pin through, then lay the bike in its side and pull the clutch lever in and put a strap around it then put the bike in 5th gear and turn the rear wheel around and you can see the clutch spin and fine tune it to get the plates to spin level. Hopefully it is less likley to slip.

    Bultaco 350T

    I rode in the first Sammy Miller trial that allowed spanish twinshocks to compete on my 250cc Ossa gripper (tank holds 4.5ltrs) The route was 40miles long and so i asked if there was someone official to carry fuel around? and they said no but there is a petrol station on the route. I carried 1/2 a ltr and put it in the bike as soon as poss, i rode as economical as possible and finished the day ok. When i got home i measured the fuel left in the tank and worked out 45 miles to the tank. i have a 29mm mikuni on the bike. hope this is of help. you could get a few small bottles to put measured amounts of oil in eg enough for two litres of fuel (safer than carrying extra fuel in a rucksack) Ps to be allowed to ride the Miller series with the big british bikes was an honour. Steve.
  19. Very sad to hear this news about Derek Allen today, He helped me with refueling at the Scottish six days trial for a number of years until the army tuck over from the private clubs. I have just a few photos of me in the Scottish and most were taken by Derek. One good memory was catching him out in the ssdt one year, i was the first rider of our club (Sheffield & Hallamshire Mc and Hillsborough Mcc,) on the road and i turned up earlier than he expected so he started to pore fuel into my bike complete with cigar in his mouth! Stephen Bisby.
  20. I have just put a new clutch into mine, i drained the oil out through the drain in the sump (front wheel on a brick) and left it for 1/2 hour then tilted it side to side a bit, i didnt bother to measure what came out. Then laid the bike on its side to work on the clutch and noted that there was still some oil left in the hollows of the main engine case. if i had to guess how much id say more than 50ml but less than 100ml. when i look in the gear box area there is an area in front of the gears where a bolt goes through both halves in the castings, this will act as a dam for some oil.
  21. I can only think of three ways you could lose? the oil. One as stated, crank case seal or gasket leaking into bottom end. Two when you filled it up if you have the bike on its side it could have come out the gearbox breather above the final drive sprocket, but you would have seen the oil. Three, i bet its still in there around the clutch and cush drive , if you lift the front wheel up and lean it to the right it can flow into the gearbox. Steve.
