  1. Softening a Vertigo

    Thanks for your concern over whether I should “mess” with my bike or not, I didn’t necessarily intend to alter my bike. As you can see from the post it wasn’t specific to a certain cc, more just a general query as to whether anyone had tried it and what effect it has? I had basically been riding back to back a very-very soft bike along with my 250 & it was a thought that perhaps people have altered motors above what the fixed maps offer? It seems fairly common amongst other non FI marques. Vertigo UK sell both high and low compression heads (but only for the 300) also a flywheel weight kit which I presume fits both cc. I’d be interested to know how you find yours “theluckyone”. Might just be me but I find the engine braking effect (possibly from the FI) greater on my Vertigo than on any previous 2 strokes I’ve ridden, presumably this would lessen with the flywheel weight as well as slowing the ability to rev up
  2. Softening a Vertigo

    Hi As the title says, has anyone tried softening a Vertigo, (of any cc) by either adding an additional base gasket or a head insert? If so was there a discernible change and how does the alteration work with the fixed EFI maps?
  3. Triumph Cub heavyweight fork oil

    Hi Has anyone got a good base suggestion for fork oil weight and the amount for Cub heavyweight (earlier internal spring type) forks? Haynes manual says 150ml SAE 30. Cheers Jon
  4. Cub rear hub width

    I'm thinking of building a spare rear wheel for a 1958 T20c, would this have had a standard or wide rear hub? Or could someone please tell me the width of each so I can measure what's in there to get another one the same size.
  5. Vertigo comparison and thoughts?

    Another vote for the 250 from me. Had a '97Mont 315r and '12 Beta 250 before the Vertigo. Bike feels much easier to static balance on. Has plenty of (useable, manageable) power, the maps do change the engine characteristics. I rode in a muddy (U.K.) southern trial recently, pulled 4th in sections no problem and had bucket loads of grip. Riding practice sections at another venue I found big(ish) steps easier than the Beta. Vertigo UK have been very good to deal with. Not had any issues with the bike so far. Wouldn't hesitate to recommend, but as always try before you buy!!
  6. Fuel mixture

    I've just bought a handful of 30ml plastic syringes so I can accurately measure my premix oil!
  7. Fuel mixture

    I questioned this with Nick at VertigoUK, as there was a discrepancy between the 200:1 (25ml/5 litres) or 0.5% and the manual, which states 0.75% which works out at 133:1. Nick confirmed the 200:1 ratio as being the correct mixture.
  8. Cub front hub and heavyweight forks

    Thanks vinnied, I've had the wheel out, so I'll loosen off fork bottoms and check it's all sitting right as you suggest. I initially nipped them up whilst off the ground. Samwisemcg, I can only compare to fairly modern forks. The oldest being standard TY175. Obviously, compared to those they aren't all that. Lift the front wheel off the ground and they clunk, but they go up and down when you want them to. As I'm not wanting to take the bike too far from "stock pre 65" they will remain untouched.
  9. Hi I have a 1958 Cub with what I believe are the original hub, spindle, spacers into heavyweight forks. There is a gap that I'm questioning on the opposite side to the drum. Am I missing a spacer? Should the hub pull through further when I tighten the nut on the drum up? Or does it just have a gap!?
  10. No more battery

    Yes, just after midday. Very pleased with it, although I've not been further than the bottom of the garden. Really noticed a difference between maps on the slippy stuff. As you have said in another post, top service from Nick and VertigoUK, top team.
  11. No more battery

    Yup 100% Built Jan 4th. Mine is a Ti, not sure if it's specific to them. When was yours built?
  12. No more battery

    Just taken delivery of a new 250. Vertigo have got rid of the 9V battery. Bike was built Jan 2017. Apologies to existing owners, I forgot to ask if they can eliminate this on earlier bikes. Very pleased so far!
  13. Doug's Wheelie

    Cheers guys I've emailed RedBull TV to see what the score is.

    Can't get film to load on RedBull Tv, anyone else currently have this? 27/12/16 20.30
  15. Beta Evo 250 2T Problem

    With the engine off, click it up into a high gear, pull the clutch in then gently rock back and forth till the plates free themselves. Once free find neutral again, start the bike engage the clutch and click it into gear. Be prepared for the clutch to drag till it warms up though, so make sure you have a nice clear run till it does!
