Bultaco

What would you recommend as a good shock absorber for a 199? I'm not a serious competitor so don't need the latest and greatest, just something reasonable with a reasonable price. The Betor Experts on it now were fine when they were in good condition but now they're barely functional. And what spring rate for an 80kg rider?

hi all im unsure witch to get rack or trailer im going down cornwall next year with my bult would a bike rack be ok all that way or would i be beter off with a trailer? thing is my wife will be driving as i dont not sayin she cant drive ??????? ah ah but im just thinking with a trailer might be abit scary

Ok guys I've taken the plunge and bought a early bultaco, as far as I know its a 71 (k reg) but it needs setting up correctly, it starts but its woolly! as in the revs are all over the place! It seems like air is entering somewhere. The inlet manifold rubber and the airfilter hose has got some splits in them? so these will need replacing for a start! An amal carb 627 type L428 is fitted and looks quite a new one! Is this the correct carb? whats the correct spark plug and ign timing? Also I've included some pics as the front brake is much bigger than standard it looks like a mk1 cota front wheel? what do you think? I've had a m80 front wheel in the garage for ages (lu…

Somewhere i was advised to strobe / set timing on an electronic ignition at 3500prm (Electrex World) If this is so, could someone enlighten me as to what throttle opening this would be please? M199 sherpa- Many thanks

Hi there, nice that i found this forum and i am not the only Bultaco addict round here...I just wanted to sell a 183 Sherpa i bought for a friend, who didn't want it anymore. When it was standing in my garage, i said to myself: he, thats a really nice bike...It was stored 25 years in a shed and had a real daily driver life before that...I put some air in the tires, brake cleaner in the carb, some fuel and the engine fired up. I could not believe when i made a few rounds with it on our place...and decided, thats my new project, the bike i always wanted to have since i was 18. crazy, and makes really no sense, cause i have three other Bultacos and a montesa trial... I …

The 'vesty replica' at Telford had a reed valve conversion. Has anyone any experience of the effects of this mod? I'd expect smoother running at low revs because of cleaner low down carburation...anyone ever tried it?

Seem to remember somebody asking the other day about jetting for a VM28 Mikuni on a 199B but I cant find the post. I've got one fitted to one but runs like poo so just wondering if anybody knew a starting point for jetting the carb as it feels week. Don't have any spare Mikuni jets so will have to order and they aint cheap so just wondering what is the starting point on jets slide etc. Thanks

My 159 after going out for a days ride then home for a good wash and polish!!

Hi all I'm just finishing the restoration of a M91 Bultaco and I've got as far as doing the wiring. The stator plate I have has 2 gold coloured coils, points at the top and a condensor at the bottom. The problem is I have no wires. What should I have and where should they run too?

hi guys does anybody know where i can get the front sprocket seal for my 199A? ive tryed the ones bultaco uk sell and its still leaking. any ideas where to get the seal with the metal clad round the ruber? i found one in a tin of engin parts i have ive put it in seems to be a much tighter fit than the all ruber ones wont know till ive put the clutch back on and start her up to see if shes leaking. ive turned the back weel round now before oil used to drip out dosant seem to be doing it with the metel seal so any help would be great

Before photo I bought this Sherpa T M80 in the spring of 2009 for $150 Canadian. The previous owner had the bike since the mid 1970

A very original looking Bultaco Model 10 round tank for sale at the show today, asking price 4K.

hello all am thinking of having one of my 199A powder coated in wite any idea witch ral code it is

I have a 1980 Sherpa 199a which I have just partially restored. i.e. frame, brakes, rebore, new carb, repaint etc etc. (Trying to relive my youth according to the wife- rode a DOT in the 60's and a slimline Bultaco 325 in the early 70's) Up until yesterday it was running sweetly. Then a misfire developed which gradually worsened with backfiring etc. Checked spark seemed fine but changed plug...... no improvement. Bike starts no bother but misfires as soon as I ride it. Checked wiring and cleaned earth connections...... No better. Waiting for a condenser from Dave R so haven't been able to try that yet. Decided to check timing and points. Points had closed down a l…

hi should the 151 350 have a breather hole in filler nut like the primary filler cap? the primary filler has a hole about 1mm on the side. but the filler for gear box under carb has just got a slotted cap with no hole, I was reading a post from 2008 and guy had over heating problems he had no vent on his gear box as mine does run bit hot I was just wondering should mine have a vent ? cheers

Hi all. sherpa 250 , how come I’ve seen some of them with 2 spark plugs in the head????? cheers

Who can rebuild these engines or at least the crank? In Motion only supply bits now. Is there only In Motion for parts? Anyone to recommend for a rebore? Will probably do bottom end myself unless can find someone to save time. Thanks.

After all the trouble starting and plug fouling it seems it is the main bearings so seals as well. Please see pic attached. Discernible movement when levered under the magneto so engine re-build it is. The pictures in my manual aren't good. They mention the 12, 6mm nuts securing the crankcase halves and not to loosen the illustrated one as it secures the friction pin though this does not apply to pre '76 models. I can't make out which one they mean. Can anyone shed any light on this? Also any advice on pitfalls to avoid gratefully accepted. Cheers Neil

Anyone got pics of a 199a or similar in non-standard colours, or modified? Just looking for some inspiration....

I have a blue 199 Sherpa with frame number JB 19902239. It has tubes under the engine and no gusset on the swing arm. It has blue frame, tank and mudguards etc. Can someone confirm whether or not Bultaco released blue frame 199 Sherpas.
