  1. I have did this to many bikes The last one was a 175 Bultaco in 1983 Had to dry it out there and then (long push home )The motor still runs to this day un opened since it left the factory Just changed crank seals and oil change Leave the motor with water in it the damage will be done as 2stoke 4stroke says
  2. I think the brakes were wet
  3. I use a standard engine and clutch sprocket setup The gear box is 13t and rear is 58t (420chain) but I use a lower sleeve gear and lay shaft gear as the bike was set up for the Pre65 SSDT which has road work The rider tells me the gearing is fine for the sections and moor work
  4. There should be a screw hole inside the clutch case just below the drive sprocket so the tensioner trails to the rear(clutch) The basic engine did not vary much I ran an early 5 speed 250 then the early 325 Now a 175 all use the same design
  5. The pistons are interchangeable One has a flat top the other has a dome but round the edge is flat The head is flat on the mating surface then drop into a recess with the dome where the valves are If the head or barrel have been skimmed the piston will hit the head as there is not much clearance
  6. The piston does stick out at tdc as long as the ring does not The piston should miss the copper head gasket and fit the recess on the head What piston are you using and was the head skimmed?
  7. I have had two engines done by Meriden off road He fitted the pillars and sprocket access plate
  8. No not this year
  9. This part is a Triumph part as some Lucas rotors used smaller holes on the early engines The part you need is the adapter sleeve e4454 as used on later engines
  10. Your rotor should be fitted on to a sleeve So you have the sprocket the sleeve {make sure the woodruff key does not touch the rotor)then the rotor I think the large ring went on fallowed by the nut The stator fits on the pegs (mounting pillars) and set the timing making sure there is an air gap all round between rotor and stator Recheck timing once you tighten the rotor as it can move as it is not keyed to the crank
  11. I also use a Miller sump guard on my cub I usually remove it when working on the bike as it covers the screws to the cases and drain plugs The Meriden one is very smart I saw it last year at the Telford Show
  12. You are ok I hardly see the trial I am in the office Might have better luck this year and see some action
  13. There is only 180 riders (183 ?)Mike Bell 100 had a 350 bullet and his son Liston rode a 500
  14. 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
  15. 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
