Bultaco

Hi everyone. Need some advice please. I am rebuilding my bike to original, it needs a lot of work. Before I strip it down i need to run the engine and check the gearbox functions. However I am stuck for a rear break plate. The problem is that mine has the (I think) Pursang rear hub, two piece hub held together with M6 Allen screws. Tried Bultaco uk but they cannot help. Any suggestions would be appreciated. Thank you in advance. Martin

i have just stumbled over trials central and realise you guys know a lot more then me. i have ridden twinshocks in local clubs since i was 15 and now being 20 i have finally started to get ok at riding i can even do a few tricks the mono boys love to show off. i am asking for general advice and opinions on mods for my 325 sherpa t butaco, to date it has electronic ignition from bultaco uk which s the best money i have ever spent on it. mark 2 amal carb and some decent bars. is it possible to get some disk brakes? better forks maybe of the mono type? and whats all the fuss with falcon shocks? can you get lighter wheels? any other mods you can think of i want to do. i …

Can anyone help. The Kickstart spring has failed and I have a new one to fit. Can this be done in situ or does the shaft have to be removed? Martin

Hi all, I have a M49 serial # M49005##, I believe it to be a so called series one. I need help with the correct rear brake lever and foot rest choice. As you can see in the pics the bracket for the rear brake lever seems to be behind the frame at foot rest level. I am thinking for this it is a long solid steel type? Any pics would help me locate one. The footrests I have seen can be the fixed platform type or the newer flip up type. Again any pics of the correct type to help me locate a set would be appreciated. Any information or chat about the M49 would be great! Thanks, :-) FRAME TOP RIGHT= FRAME TOP LEFT= REAR BRAKE FRAME BRACKET= LEFT SIDE VI…

Well didn't know if to start a blog or a forum topic but chose the latter. Some of you know I have a 199B Sherpa amongst my twinshockers and it's been with me a long time, BUT I had a long hiatus from the sport and a shorter one out of the twinshock business. Being slightly disinterested for a while meant I didn't even look at my bikes let alone look after them much, they had been in storage and thats about it. All "Fired Up" again now though and really feel guilty I left my bikes for so long, I also realised I'd lost out on a lot of fun. So my punishment begins! and the bike was completely torn down when I returned from a trial last Sunday. Took all of an hour to…

Hi, Is it difficult to fit bushes to a swinging arm of a bultaco sherpa. Thank you in advance egsmyth

Group, Need some suggestions: I ride a Model 92 Sherpa T in Trials. Totally stock bike, points, AMAL carb. Great bike, runs fine, rebuilt about a year ago. Plenty of power, very good throttle response. My problem: It isn't now, and never has been a "first kick start". 5 to 7 kicks when cold and usually 2 or 3 when warm. This is a real pain in Trials where you have to start the bike about 30 times in an afternoon. Any suggestions to improve starting. I don't even care if I loose a little power. Thanks in advance. Alan

So you think you can ride a Bultaco! ..... Found these on the net of a young man at play..

What shoud these be replaced with? Ive heard varying reports of new replacement ones failing, or of people fitting 2 single ones each side. Whats everyone using? Thanks

Hello, I have recently bought a Bultaco with SM high boy frame; I did it not because I hope that his frame is much better than the standard one but because I believe that it is a peculiar bike in trials history. The bike I bought is rather a patchwork: engine, forks,hubs are a nice collection coming from several bikes and so the problem is: how was the original bike? Even I'm not totally crazy about each original screw of the bike (especially when prices are rising at stars) I'd like at least to have the right engine, wheels and suspensions. A fast search on the internet (this fantastic source of informations that so often provide us of good informations) didn't give me …

Can anyone help with a source for 199b Tank Decals? I'm looking for vinyl rather than water slide transfers - I've tried the water slide transfers and I can't get them to stick to a poly tank. Thanks in advance Paul M

This is my first post on this forum but I have been viewing the topics on the board for about a year. I own several Bultaco's and I am very knowledgeable about the brand and many of the models they produced. I have been riding an M159 Sherpa for the past 5 years in vintage events. This past year I have been using it in the vintage class but we ride junior type sections. Myself and the other vintage riders find the junior sections more than manageable on the older bikes. Last year I got an M199B sherpa t and I am just now finishing off the restoration. I use that term rather loosely as all I have done is blast and paint the frame, new tires, new cables, brakes, and a…

Hi Bultaco Sherpa T M49 - Does anyone know if there is meant to be anything special about the teeth on the engine sprocket, or are all mine just worn? The teeth appear to be the normal involute form (as in any chainwheel) but with the outside diameter then reduced. Has the proximity of the chain tensioner anything to do with this? It may well be that mine are worn and I shall have to look at replacements. Thanks Sparks2

I'm determined to actually get this 325 model92 going again, I've had it for 11 years and not a lot has got done to it. I'm in need of a fair few parts for it, I half wonder whether to abandon it and get a complete one. In reality it shoudlve been scrapped years ago! Its good points are the motor is excellent, its road reg, and tax exempt! I need: Exhaust Front wheel Swingarm spindle Seat for slimline tank brake pedal gear lever Chain guard chain tensioner Any pointers on breakers? I dont have time to trawl ebay. Or does anyone here have any of the above surplus? I'll post some photos of it tommorrow. Thanks

You've bid on that twinshock, sometime on Sunday evening, with assistance from a nice glass of wine and a loosened finger on the mouse button. Anyway, went round to see Gavin (read more here) and his latest acquisition, what he thinks is a 1971 Model 80 Bultaco. The recently finished Montesa 247 looks concours, but this might be more of a challenge. All other horror stories or comments on the Bultaco welcome :-)

I visited a bike boneyard to look at two M49s and luckily they were examples of a series 2 and a series 3 bike. This posting has the photos of the series 2 M49 serial number M4902195 and the next posting shows the other bike. What got me motivated to go looking was a post by Woody: "The serial numbers are from Bultaco's own figures so they should be right. However, they only list the model 49 as having one frame change during its production run but there were two. Series 1 with single tube under engine, upright shocks. Series 2, single frame tube under engine, angled shocks with seat unit altered to accomodate relocated top shock mounts. Series 3, twin frame tubes under…

I have a 1974 Bultaco Model 125. But I see that they made three models during that year, the 92, 125 and 133. I can't see any glaring difference, does anyone know what the differences were?

Just found these photos on the French Le Guide Vert Enduro website (merci mon ami's ) Looks like an interesting 4 stroke Sherpa conversion...any guesses as to what they have used? Martin

Can anybody tell me if this company is still in business?? I have been waiting for a parts package to arrive for about a month. The parts were prepaid and I get no answer back from Dave Renham about the whereabouts of my parts. I wondering if anyone has info??
