  1. You are ok I hardly see the trial I am in the office Might have better luck this year and see some action
  2. There is only 180 riders (183 ?)Mike Bell 100 had a 350 bullet and his son Liston rode a 500
  3. Check the boot on the M/C between the lever and piston I saw one rusted under the clip and washer not letting the piston fully return causing the same problem of holding the pads on
  4. Bike was used today and went well with the longer inlet track and carb more upright Changed the slide as well Yes they were never fitted with this carb but that was all you could get new when this event started My B31 never ran right with the concentric but now runs as sweet as a nut on the new monobloc
  5. I have a 175 Bulto with Renthal bars Some year later bought a 250 and it felt different Every thing measured the same The 175 was comfy 250 not so till I measured the bars the 175 had been shortened by me when I bought it new So it is what suits you Renthal make different bar my cub had Enduro bars on (wrong shape)
  6. Yes I have also used other carbs but the bike is entered for the SSDT Pre65 so requires an AMAL to be fitted PS Project on going
  7. Yes I have one fitted to my cub Just fitted a longer inlet tipping the carb to less of an angle and fitted a 2.5 slide today Still to be tried out It has a flat spot off idle but it may not be the carb but other factors ie ignition or exhaust The rider said it felt better (to icy to really tell) and could not get the engine hot
  8. I have the same problem When I got my last pair the optician moved the distance part of the lens down I do not use them in trials yet but need them to drive on the road (to be legal)I also find when making part they look bent when they are really straight
  9. Just an add on Carbon can also build up at the bottom of the groove not letting the ring down in its groove (new rings are bigger than worn ones) I always clean them out using an old broken ring be careful not to remove any metal of the piston
  10. Hi I also have an engine marked like this Mine is a roller crank and distributor drive hole Yours looks like the 62 onward type by the shape of it (at rough guess) Rocker gaskets can be obtained as separate parts I have cases where the engine number is on the front mounting bolt lug
  11. You just need to undo all the small nuts on the and the allan screw just behind the front engine mount (on the picture0 I left the gears on one side and crank on the other It is a long time since I did one about 40years I think
  12. I have my rev3 2003 off just now did exactly as above post This bracket also holds the centre box of the exhaust That screw into the rubber mounting
  13. The person using mine says it is ok the first lap when stopping to look at sections but next laps where the engine runs for a long time it gets hot and the power is dropping but there may be other factors causing this as every thing in the engine is new
  14. Yes it does not seem a lot The engine is still being set up but I do not ride it It looks and performs ok up till now but may be different in the Pre 65 Scottish or road work for oil cooling I am working on that also
  15. About 900 cc Will take more if engine and piping are empty but not much more
