Bultaco

Has anyone tried fitting a flat slide Mukuni 28mm carby to a Sherpa T? I ordered one and would like to know what to expect. Anything to watch out for as far as tuning, throttle control, etc?

Does anyone have the link please to the trial held in Belgium in the 1960's where a young Jacky Ickx was riding a Bultaco.

Hi Guy's, What's the best tool or method to compress the clutch spring to remove, and reinstall the pin's. are they under a lot of tension. Ive got a Haynes Bultaco manual showing a Sammy Miller Tool for the job, probabley expensive Cheers.

Hi guys. The hub of my front wheel is broken as you can see. Is anybody out there who can offer me such a hub? I tried it at bultaco.co.uk but unfortunately they don't have one. Also ebay wasn't successfully. Thanks, Felix

Can anyone help me find a bultaco sherpa/alpina rolling chassis? Preferably at about 400$ or less. Thanks.

Asking for a friend...for those who by necessity or design choose to install a mikuni carb on an earlier Alpina or Sherpa T what have you found to adapt the airbox side 1.75"o.d. carb flange to the 2" i.d. rubber airbox intake hose ?Thanks Alpthusiast?

Hi Guys My bike ( a 1975 159 325 ) has been sitting for a long time and the carb was full of gunk and the orings has rotted away. I cleaned the carb up and ordered some orings from Bultaco UK but it's not all all clear where the 3 orings actually go and the exploded diagrams dont help either Can you tell me where they go please It looks like oring 3 goes in groove C oring 1 fits the diameter of slot A but doesnt seem deep enough - thick enough - ie in can move up and down the groove I have no idea where the other oring goes ? Hope one of you can advise

Greetings, All- I just found a campeon kit tank / seat the other day. The seat is toast, but I can get one from In Motion. The fiber glass is in incredibly good shape and after a Caswell coating and repaint, it should look great. here's my question; If I use this on my 191 project, can I use the standard air box or would I have to acquire and earlier air box like on the early to mid 70's Sherpa T? Or should I use this as an excuse to buy another older Sherpa T? ? I haven't gotten the tank yet, so I don't know. Thanks, Herman

Hi I am in the final stages of rebuilding my Sherpa 80 series motor. Bottom end is complete and fine. I am about to fit the new piston and any clarification on side play at the small end would be helpfull. I have 2 Sherpa the other is a 198-A which has recessed spacers between the needle roller and piston. The new piston for the 80 engine is not machined either side of the small end, so my question is :- A Do I turn some recessed washers and equalise the conrod with the pistons centreline minimising side play. B Not worry and just use the plain washers supplied by bultaco UK and thin them to minimise the side slack on the end of the rolller bearing allowing the…

Hi, I have a M91 Sherpa which has the early style rear hub with a bolt on spoke flange on one side and a 140mm x 40mm hub on the other. Does anyone have a measurement of the offset for this type of wheel please? I have measured mine however the rim is massively buckled no wonder the tyre touches the chainguard, shocks and swingarm! Thanks

Hi, I was wondering if anyone could give me more specs of the Tail Light Bulb (Part No. 26.21-047) used on a 421-048 style tail light. I currently have a single filament bulb. The only time I can make the bulb light up is when I close the hi-beam switch. I am wondering if it is supposed to be a 2-filament bulb. If possible, can you give me a more commercial part number rather than a Bultaco serial number for the proper bulb. If the part numbers referenced above are not factory part numbers then reference the Bultaco.com website and service manual for details. Thanks

Hello, Im looking at buying a Bultaco to restore and hopefully ride.I have found a nice possible project but the problem is the engine number and frame number are different.This is a 1967 Sherpa 250,so the question i have is, Is this still ok to buy would there be any problems with having different numbers.Many thanks to anyone that replies.

Just spotted this on ebay 340 Bulto For all those observant ones amongst us, its a Mono. Now I think this one may have originated from down in the Wessex centre, as I can remember a local rider who did the conversion using a Fornales air shock from the first model JCM. The bike was tested in TMX by Martin Strang, Geoff Parken and Nibs Kellet. Unless anyone knows different Martin

hi guys anybody seen the 199B on fleebay? was thinking of buying it but the guy told me it takes 20 kicks to start it.and sombody else whent to look at it. and said the gears are rough.and couldnt find 6th gear sounds dodgie to me. glad i didnt go though with buying it know.

I need a kickstart for my M91 and have seen one on ebay for a 199 ( must be yours bondy). Does anyone know if the 199 one will fit the M91? Cheers

My Bultaco 199A has had an alloy petrol tank from new, most of the similar 199A bikes that I have seen have a plastic tank fitted as did many of the previous model red Bults & the 340. Was the alloy tank an option or was it only fitted to certain models?

hello all need your help ive had my yoks powder coated in blue i told the guy not to get any paint inside the yoks theres not alot but anough to stop me sliding my tubs in so how can i clean it off?

Ive had my 198b barrel rebored but the guy who did it had an accident with it and had to resleeve it. Im just wondering if anyone could supply the port measurements so i can check that these are correct. Big ask but someone might have a barrel off for restoration

Does anyone know the torque specification for the crankcase nuts on the left side of a 250 cc (M91) engine? I can't seem to find this info anywhere. If not an "official" spec, then I would at least appreciate a reasonable figure to use in the opinion of the experts here. Please also indicate if this torque would be the same for the single recessed hex-head bolt at the front of the crankcase. Many thanks!

Good morning my 350 Alpina came with a broken kickstart spring can I replace it without splitting cases, if not what is the procedure to complete the job. Tia
