  1. Swm 125 fork problem

    I don´t know about your forks but there can be a short spring working in the opposite direction preventing problems with bangs when fully extending the forks. Ought to be some form of device, hydraulic or mechanical.
  2. Foam air filter spray?

    I use Castrol Filter Oil Spray. Have done so for at least 10 years. It gets very sticky and will effectively stop dust and particles. I have found 1 Not to use too much and only at outside of air filter. 2 Let it dry before starting the engine. If wet it can be sucked into small passages in the carb and make problem. I spray the day before I go out with motorcycle. I think it is a very good product but takes some care to use.
  3. Bleeding brakes

    Interesting. Thanks
  4. 199A running refurb.

    About the countersunk screw....When rounded sometimes you can take a hammer and bang in a torx bits. Not perfect but can work.
  5. Sherpa 250 T clutch spring setting

    To get correct setting I use steel lock nuts (not nylock). Locking wire is not needed. Much easier.
  6. Bultaco 199A Ingition

    Might be of interest. I have one Femsa flywheel for 340 marked VAR 41-52 and one for 250 marked VAR 41-51
  7. BSA Conical hub shoes.

    Perhaps try these people https://www.feked.com/triumph-bsa-front-brake-shoes-6-conical-hub-tr5t-tr25w-b25-b50mx-b50t.html
  8. Montesa 315r oko carb

    I bought mine for Bultaco from here http://www.mid-atlantictrials.com/Sales.html. Works well on Bultaco Sherpa. They have one kit for Montesa 315
  9. 2T Petroil mix

    v1nn1e: Your calculation is correct 1.5% is what I use for trials two strokes or 75ml/5 litre Or Aspen 2-stroke petrol which is 2%. /Carl
  10. Sherpa 198 Amal mk 2 carb settings

    I don´t know about Bultaco Amal settings but a slide with no 1 opening.......That sounds incredibly rich. I think something between 2,5-3,5 would be normal. Throttle opening comes into effect just above idle and flattens out at approx 1/4 of opening where needle and needle jet is more important. I see Inmotion list thottle valves with 2,5 to 4 openings.
  11. Spark Plug Gap with Electrex

    I use Electrex Bultaco ignition and Champion N11YC at 0.6mm. No problem att all so far Carl
  12. TY175 Progressive Clutch?

    I don´t know anything about Yamaha clutches but generally speaking: Clutch centre and clutch basket must not be notched and clutch plates must be in good condition. I think thin oil is better than thick oil. I use engine oil 0W-20 to get a drag free clutch Carl
  13. Crusader / Bullet - forks advice please

    But... ..would not an Indian Bullet engine be considered as pre-65? I think they should. And to gain ground clearence you should cut the oil filter away.
  14. Crusader / Bullet - forks advice please

    Bullet forks are pre-65. I am not shure about the MZ forks? For modern steering you need 20-22 degree headstock angle and a front wheel spindle that sits 60-65mm in front of headstock centerline. This will give you a proper rake with a 21" trials front wheel You can use parallel yokes with (1)all offset in the yokes. (2) Yokes with part of the offest in the yokes and the rest in the lower fork legs (like modern bikes) or (3)nonparallel yokes. Bultaco Sherpa use a combination of (2) and (3). I use a modified (replica) Crusader frame (20 degree angle), Ceriani forks (1961 type) and my own nonparallel yokes for a front wheel spindle offset of 65mm and I think it steers well. Carl
