Bultaco

Hi, Been looking over your site and lots of good info. I'm fixing up a 199A and it does not have a head stay/steady. I ordered one from In Motion, but I have two questions. First, is it really necessary and do I need to re-torque the entire head bolts and nuts? The guy at In Motion said only do the two that hold it onto the head, while a shop here in the States said you should loosen them all and re-torque. Not sure what to do.

Hi I need a 199b manual…. Anyone got a pdf they could share? Thanks nick

I have a 350 1975 Sherpa T and want to fit a speedo, primarily to keep track of the number of miles covered. Is there a kit you can buy for the complete installation. Many thanks Borderlord.

Does anyone know how to get a replacement Certificate of Origin for a Bultaco in the US? I lost mine years ago. My Sherpa T 199 was originally sold by Cycle Sport Bultaco in Houston Texas. I am trying to get it registered in Massachusetts.

Hello All wonder if you can help me. I have sherpa 325 and wonder if you can get a modified top yoke where the handle bars brackets are more forward instead of the standard ones where the bar brackets lean back? I hope this make sense. Many thanks

Does anyone know where I can get a stick-on B&W number plate for my (1967) Sherpa. I've found a few places that do rectangular ones, but non that do those old 60's style B&W ones that will stick to the rear mudguard. I dont really want to mount a flat plate, Id rather stick one on so it bends round the rear mudguard without sticking out.

Hello, I started the project of rebuilding my my 1973 Sherpa. I’m quite young, without much previous knowledge. Regrettably. I’ve got the bike all apart. I’ve had the frame powder coated etc. However after taking the engine completely apart. With my lack of experience. I’m beginning to struggle and get overwhelmed. My hopes is to learn from this project and gain skills from it. So I don’t want to give up on what I’ve started. I’ve been using a few different manuals such as the Haynes one. I’ve bought some parts to replace, such as new gaskets, electronic ignition, clutch plates etc. However I don’t really know the key parts that should get replaced in a rebuild. The gears…

Just to say Hi....just delivered yesterday is my 250 Sherpa. had a Miller High boy 250 back in the 90's and sold it to fund my road racing. bad move!! Anyhoo, Iv got a frame number PM 15000445 and engine B 8002817, any ideas on the year and model?

Does anyone know the maximum overbore for an M116 Alpina? When I bought mine 20-odd years ago it had been left outside with the head off and no piston, just a sad rusty con rod flapping around in the cylinder. A quick measurement with vernier calipers shows the bore is already at 83.8-something mm, so probably was on second overbore (83.75) already, and it is quite rusty. It might just clean up to 84mm, but that could be wishful thinking. I know that at some point they went to a thicker liner that could be bored out further but I'm not sure when the change occured. Currently the liner is about 3.6mm wall thickness so would have been about 3.85mm or so when new. I see ther…

Just bought this fixer and not sure about the year and some details if someone out there could help and recommend upgrades. Noticed brake is on left side and thought they were imported with it on the right after 85? also not sure what those shocks are from. have some rust on the upper fork tubes can that be fixed? Many thanks in advance.

Hi All, I'm looking for recommendations on what the best 2 stroke oil to use is for my Bultaco 125cc M89. Or is it that all 2 stroke oil is the same? Thanks, Todd.

Will the Haynes workshop Manual for the Bultaco Sherpa T 1972-1975 cover my Sherpa T....................... engine number JM-15900493 Many thanks Borderlord

Hello, What is the height of a bultaco sherpa 198A (72mm) piston. I would like the height on the intake and exhaust side (X= and Y=) thank you so much

Would appreciate it if someone will point me in the right direction. I need a set of clutch plates for a 1975 350 Sherpa T........engine number JM-15900493 I'm in the UK. Thanks Borderlord

Hi all, Hope that you can help! I am currently in the process of restoring my Dad's old Bultaco Pursang Mk5 125cc and have stumbled across wiring problems. The project is for his 60th birthday and was left to rust in his shed for over 40 years! I'll add some pics below to show progress. The engine has been rebuilt recently and I was told that I was lucky to have a functioning Coil and Stator as he told me that the engine was sparking when it left his shop. As the frame has been powder coated, i made sure that the engine is grounding to the bike by removing the powder coat at the bolts. the problem i have got is 4 wires... yes 4 wires. I …

Maybe useful, there's a few VM carb threads here. Mikuni Tuning and Jetting Guide - THE VINTAGE BIKE BUILDER http://www.vintagebikebuilder.com/mikuni-tuning-and-jetting-guide.html The OKO is a VM copy from what little I know so may help on these too. 😎

I have an M85 frame from an Alpina and wonder how different, if at all, it is to the Sherpa of the same year. I have a Sherpa motor for the same year and would like to make into a complete Sherpa if the rake, trail and wheelbase are the same.

Title says it all really.....or more a case of what was lying around in the p*** and panic before they closed up shop? Many thanks guys, stay safe

hello, I have a problem with my bultaco sherpa. the bike don't want to take turns. it is very soft on acceleration. I have a well adjusted carburatzur phbl26. What is the problem. thank you

Im new to the forum. Before I take it apart I thought I’d see if anyone had any ideas. The photo of the gas tank mounting bolt shows the tank is off the frame quite a bit and the header is still in contact with tank. Any ideas where to start?
