Bultaco

  1. Started by swooshdave,

    I gentleman over on TeamBultaco (Yahoo Group) posted these pictures. With his permission I'm reposting them here. Does anyone know the history behind this bike? Were they ever produced?

    The offset pivot arrangement for the brake shoes in both wheels of my M198 had me wondering if there were brake shoes from a different bike that would fit and not have the offset pivots. I'm trying to maximise the performance of the brakes by avoiding the eccentric loading against the drum that the standard bultaco pivot arrangement creates. I have looked in the EBC catalogue and there were a few alternatives that looked like possibilities. Fantic 240 shoes appeared the closest in the catalogue. They are for the same diameter drum and are the same width shoe and use a standard pivot arrangement. I know I can have the existing shoes modified by welding and machining then…

    This year is the 50th. aniversary of Bultaco CEMOTO 1958-2008. Trials bikes started to be built in 1964 with the first 3 prototypes of the Model 10 "Sammy Miller". Happy birthday, and thanks for so many trials enjoyed. Thanks BJ for this pics, it would be nice to see more Bultaco photos here.

    I need help from you Bulto experts(please)!What is the best way to achieve a one finger clutch operation on a 199?Years ago I used a front brake actuating arm on the clutch to give more leverage(but I'm struggling to get hold of one at the moment!!!)and also backed off the clutch nuts at the expense of clutch slip when pulling a high gear.I can probably rig up a lever system in order to give some mechanical advantage,as I have on my B40 but on the Bult it will be difficult to package it neatly.Any suggestions?Also,is it worth replacing the Bing carb with perhaps a Mikuni?Your replies are appreciated!

    Since we are on the subject of 199s I have a question about the rear brake. I just converted my 199a from a left brake / right shift back to a left shift / right brake set up. I used an original bultaco cable that runs through the frame from the right brake lever to the left break drum. While the brake does not work nearly as good (as I expected) as it did with the rod action of left brake peddle set up it does not work nearly as good as I thought the cable might work. I find the right brake lever comes up to high for easy access with the foot and the braking action of the rear wheel is less than I thought it would be. Do any of you have any tricks or advice on how to g…

    Hello all, just rode Pa's 350 Bulty 199 (1979) in a trial at the weekend, and i'm still suffering with left arm tiredness (boo hoo) The clutch is really heavy (and virtually useless). Any pointers or tips? The Italjet is having a bit of a rest, so I'll use the Bulty for a couple of trials. Cheers

    Hi there: there is a debate in Spain about the model 198B. Some say it never existed, some say there where very few bikes produced and all exported to UK and France, even some say it had only 5 speed, not 6 as the 199B. All the Bultaco documets from the factory disapeared when it close in the 80

  19. Need photo's & help please. Have purchased a airbox assembly & side panels from Sammy Miller. The assembly consists of the airbox only !!, no filter access cover available ! The airbox supplied has a large hole at one side for the filter, i assume i will have to make a access cover plate. Also how do i fit the narrow pin side panels supplied. The airbox has no holes or grommets etc. Can anyone help with photo's of the genuine airbox & filter access panel c/w nut etc. This would help me figure out. In hindsight should have waited and bought a good secondhand one !!!!!!!
