Bultaco

Hi all, I have an m49 that I'm starting to restore. Wanted to get your feedback. It needs all paint redone. Since all sherpa t's look similar, I was thinking of doing a flat black look. Black fiberglass, bars, rims, frame. All other metal and aluminum would be polished. My fear is that it will look like a metal mulisha reject bike and I'm not into the fmx crap. Any thoughts? Trying to be different and also not have to do three color paint job.

Hello, I just purchased a model 85 alpina and want to know how hot it should be getting, Im getting about 260 degrees off the plug with a ryobi laser heat gun. Too hot or just right? seems to run alright but i dont want to blow it up. I just would like some piece of mind. Thanks.......Kevin

I recently bought a bultaco alpina 350cc from bord na mona and it turns out the bikes numbers are different the frame is a 187 and the engine is a 138 the guy we bought it off of said it was like that when he got it in 1976 when he bought it off of harry lindsay in dublin so does anyone know how this happened or was it from factory

Over at the recent Bristol Classic bike show in Shepton Mallett, saw this & knew there'd be plenty of you guys interested!!......

Quite happy with the way this is going so thought i`d put a couple of pics up to see what you guys think. I`ve got a new in-motion seat cover to fit and give the bike a good check over but its running well enough since the mikuni carb conversion has been fitted. Hasn`t been a cheap build but okay considering the state it was in when I got it. Another one saved from the scrap man.

Has anybody bought any modern wider alloy footrests that bolt straight on to an early sherpa (model 80 ) ? If not do they come with the pivot bracket ? Ive seen the older type but dont realy want chrome , at a push i could make up new hangers as on the model 80 they bolt on any suggestions appreciated thanks

I'm almost finished restoring my Sherpa T 250 circa 1966. New rims, new tyres, new spokes. Just had new brass bushings put in the brake plate. New shoes, new cable inner and outer. Brake arm works fine, shoes contact the inside of the drum fine. However, with the brake lever fully pulled I can still roll the bike forwards. Oddly it locks up the wheel if I pull the bike back, but forwards no chance. Stopping would be nice before I attempt to ride the bike. Has anyone some suggestions to what I can do next to make it work ?

Does anyone know if some markets possibly got 199B's with top triple clamps without pinch bolts, IE: taper fit. I've seen some conflicting photos, some with pinch bolts and some without. Also some appear with amal carbs and others with bings? Was it possibly Bultaco throwing anything on them before they shut the door?

I have just started restoring a 1976 Bultaco Sherpa t 350. It has matching frame and engine numbers, and I have owned the bike since 1985. It is fitted with a chrome frame, and I was wondering if Bultaco ever produced bikes with chrome frames. I don't think the bike has ever been stripped before, and it is definitely a standard frame, just in chrome! Any information would be welcome.

Hi all Just picked up a sherpa model 80 with a sammy miller replica frame, needs quite a bit of work and is going to be a long term project I think. One of the worse bits is the threads on the barrel where the exhaust screws in are gone, can these be repaired? cheers

I am looking at ideas to convert my 159 chassy to right side brake, does someone make a kit? I do have a left side shifter, I have studied the 199b set up and figure I could manufacture something that would work, I am handy with a welder and have been working on different designs, I would like to see pics of what others have done to slove this problem before commiting to welding something to my bike

Okay, so this is not really trials related but I suspect someone on here will be able to offer some advice. I have a Bultaco, Pursang which I have been building and is pretty much all done, however I cannot get a spark from the Motoplat ignition. The ignition is the internal rotor type 63mm rather than the external rotor trials type. I have taken some measurements and referenced them, the coil and stator both seem to throw odd values. I have tried contacting UK Motoplat both via website and Ebay listing but no reply has been received. I have also tried West Country windings who tell me they cannot repair Motoplat. Does anyone know anyone in the UK that could…

Hi I have a M159 Bultaco 350 and have consulted both Haynes and Clymer manuals Please can anybody give me a tip for removing the following bobbin that has attached itself to the crank, presumably with the O ring that appears to have died inside it? This bobbin is not mentioned anywhere, but I assume is common as the steps in the crank at this end appear common to more than the 159. Also, please confirm: 1. Remove bobbin 2. Replace O ring (about an inch in diameter) 3. Replace seals in carrier 4. Replace bobbin 5. Replace weight and re-assemble the rest of it etc.. It's just No 1. I can't find any reference to and am struggling to remove! Cheers Mick

Just wondering if anyone read the article on Vestys Bultaco x-lite project and what they thought? I think it,s a pretty trick looking bike and pretty cool that he is building what could have been.

Can I use these bearings on the crankshaft? They are the same size but does it matter that they are sealed? I have to heat them to fit them back in to the case. I have started to re assembly the engine that came in the basket case of parts. It appears that almost all of the parts are there except for a few. The other question that I have is if the kickstart assembly looks like it is set up properly? I think I have but this if my first time doing a rebuild. Thanks for the help Sunny

Hi i am looking for a set of fork stanchions for my pursang 370 mk11. 35mm X 645mm Can anybody put me in the right direction. Thanks

Hi guys, i am continuing with the restoration of my M-80 and am looking for guidance on removing swinging arm bushes prior to grit blasting and powder coating frame and swinging arm. Any tricks or tips? By the way is

Just rebuilt a pair of wheels for the 191.Polished the hubs,got Mike Danby to re-line them.Inmotion supplied Morad rims but I had Central Wheel Components supply spokes.I have Michelin H/duty tubes and IRC tyres + security bolts ( all from in motion) but the rims aren't drilled for the security bolts.Has anyone drilled these? Would put it opposite the valve but anything else I should or shouldn't do?

Hi there, we have a problem since last week we put a second Sherpa 183 back into life . Engine is totally rebuilt incl. new piston, crank etc. Ignition is the old femsa. new points fitted. new carb. clean filters...When you ride, after one hour, the engine suddenly stops. We have ignition spark, but bike wouldn't start again. If you change ignition plug, it starts again but runs only 30 minutes, then the same procedure, but bike doesn't start with new changed ignition plug, although we have good blue spark...do we have to live with an 1,30 hour riding bike? any ideas?
