  1. Obviously, both are entirely possible The electrical energy needed to run the fan increases the load on the alternator / engine and drags the tickover down a little If the output of the alternator at tickover is less than 12v then the fan will run slow, increasing the alternator / engine rpm and thus the voltage will increase the fan rpm
  2. In Pre 65 trials where we like to ride 'something different' there is a lot to like about that bike !
  3. No, the swimmer. The photographer looks like Barry Pickard
  4. If that was on a 4RT, the Honda locking nuts with the metal blade inserts are one use only, either buy new ones when you change the sprocket, or use loctite on the threads. Nice repair, any distortion from the heat?
  5. I purchased a carbon fibre shark fin to replace the white plastic one on my 4RT, it wore away twice as fast as the original. I bought an a small offcut of 4mm 'wear strip' from my local plastic supplier and made 3 more for a Fiver. Still have the 2 spares hanging on a hook years later. Case saver around the gearbox sprocket is important on a 4RT, seen a couple of flywheel covers broken and boots covered in hot oil pushing the bike back.

  8. 250cc Twin Cylinder Scooter motor, think there was a Triumph badged version too.
  9. You can move the brass needle valve seat in the alloy float bowl easily enough, Take the banjo fitting off and heat up the float bowl by putting it in boiling water for a minute then tap the needle valve seat up or down with an aluminium drift. Check the float height by turning the assembly upside down, fine tune it by bending the float tabs slightly
  10. Ayle is cancelled as both the venue and the river are frozen solid with more snow forecast. I presume Stanley have stepped in to offer an event. The VMCC event at Butsfield is described as an event for British (Pre65) bikes
  11. Yes, as I said, It made my clutch scream and judder and the oil came out very discoloured after a fortnight. Elf lasts 6 months between changes and comes out looking like new.
  12. No it isn't. The clutch will scream and judder. The only oil that works properly in the 4RT gearbox is Elf HTX 740 and unfortunately it's getting harder to find. It's also very expensive when you do find it. Loads of threads in the Montesa forum about this.

  14. Whatever you do, don't over soften the boots. Damaged feet take ages to heal - I know from miserable experience, blackened toes don't like changing gear!!. These days I just wash the boots with the bike and don't let them dry out and stiffen completely, then wear waterproof socks - sealskinz or MOD surplus seem pretty good at keeping the water in.
