Bultaco

Hello, A few months back I aquired a '77 Bultaco Sherpa T 350. It is a model 183. Bike came with a street ownership. It is equipped with Headlight, taillight, horn and all the necessary switches and buttons. I'm building the bike with the intent of using it to improve my riding skills as well as participate in the occasional vintage trial event. I've been removing the road going equipment to save weight and prevent any wear and tear to these items. One day when a full restoration is in order I can reinstall these items. I'm worried I may damage an aluminum fender or hard to find/expensive component like the speedometer. I've been tracking the weights of the items…

How do I get the bearings out of the swingarm? Is it all pressed together? Thanks...Dan

doe,s anyone know out there, what a bultaco m10 is worth these days??? unrestored but all there!

I have moved from boxes of bits to what could be called something that resembles a Bultaco m159. I have posted a few before and after photos. I am still struggling to get it running. It started and ran for a few moments but I have not been able to start it since. It has spark but not great and it still has big carb issues. I think I need a rebuild kit for a Bing. Leaking fuel from bowl and out the bottom very quickly (overflow hole). I painted the old fenders with Rustoleum Universal paint for now. I do not hink it will hold up but that new spray paint can they have is awesome to use big fan spray and easily to hold. I still need to order new bars and a new petcoc…

I'm in the process of removing forks from an M85. I need to pull the tubes down out of the clamps but am not sure how to proceed. Is the top of the tube tapered and fit into a taper in the top clamp? Where can you provide some force to get them moving down? (There is some corrosion.) Trying to twist the tube by hand does not work. The right fork seems to function as normal. However, the left tube is stuck at a length maybe 2 " less than full extension. The lower fork tube will rotate on the upper but that side does not want to compress or extend. Any suggestions?

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

Hi the baffles in the mid box have came loose inside the mid box, any ideas for an easy fix. It also has a strange after market tail pipe do you think this will effect performance. Once I have cleaned and repaired the exhaust does it require any packing? PHOTOS http://s810.photobucket.com/albums/zz27/my...before%20start/ Cheers

Can anyone suggest/recommend someone to knock out some dents and repaint a Sherpa aluminium tank, 199 type. In the UK.

Hi there, I have just bought here in Mexico a Bultaco Sherpa, which the vendor was advertising as a 1971 Sherpa 250, but on inspection appears to be a 1974 Sherpa 350 (model 125). It was bought unseen (comparatively cheap, that is my excuse) and when it was delivered to me I discovered that the frame appears to have been repaired / strenthened on the downtube near the headstock. I have had a good look and cannot establish whether the frame fractured and was welded and braced, or whether it has been strengthened - I am inclined to believe the former, given that the forks are slightly bent, suggesting that it may have sustained a heavy frontal impact - the front rim still …

Hi, there seems to be many opinions on this,I am just wondering what you use. I know that I always used filter oil on my motocrossers but others used 2 stroke oil engine oil or gearbox oil. #What do you think? Cheers

Hi are there any major differences between M-49 and M-80 frames? Cheers

Hi, I have been told that you can run an M-80 250 with a 626, could it run ok on a 625 as I have a good on in my garage. What are the main differences between them ,625 has a cold start lever not a tickler so it may be a model 1.5, Cheers

Hi, need advice on replacement carb for M-80 sherpa. Would an amal Mk2 be suitable and any ideas on jetting, also can you get an adaptor for flange as Mk2 is just a circular fitting? Cheers, Myson

Managed to purchase a standard airbox for my 340 from sammy millers moons ago. It now is being fitted to replace the 325 type. THe only problem i have is the rubbers and circular plate etc. Where can i get them from. Any ideas or pics so i can fab one.

I have gotten the M159 mostly back together and tried to get it start up (borrowed petcock off of M80 and fixed the throttle with epoxy and and a sqaure nut to act as a throttle stop). I did start after many kicks!!! But there was fuel everywhere dripping quickly out of the bottom of the carb. I did disassemble and "clean the carb" when I was going through the bike a few months ago but it was pretty clean to start with the photos are from the intial cleaning. What would cause the fuel to drip out?

Hi all, I have been helping a friend rebuild a Model 159 which was bought as a basket case. We have a problem with the cutch at the moment. The arm will not disengage the clutch. It is as if the puch rod is too short. I am fairly confident all the drum, hub and plates were assembled ok. We put the thrust washer in with a spot of grease so it didn't fall before all was assembled and we didn't forget the ball bearing. Looking in the Haynes Manual there appears to be a 'clutch rod extension' It looks like a short piece of pushrod. We haven't got one!! Should we have on for this model? Where does it fit? So at the moment we have as follows - operating arm - pushro…

Hi, I have scraped all paint off headstock and cannot find a frame number. The heabstck looks like a different material from rest of frame and it didnt have original silver paint(frame has been painted a horrible colour over original) Could frame be more recent than engine, it looks like M-80 and has slimline tank seat unit. Could it have been altered? See link for photos Cheers http://s810.photobucket.com/albums/zz27/myson/

Hi, just took seat/tank unit off and no air filter fitted. what filter and do I need extra bits to locate/hold the filter? Also found engine no. but where is frame No? Cheers

Hi, I have just bought a sherpa to re-live my youth after last owning one as a schoolboy in 1976. (funny thing age and nostalgia) Anyway it occured to me that we now only buy unleaded fuel and wondered if the different octane rating affects the engine or is an additive needed? I have read with interest the items related to fuel/oil ratio but would appreciate any advice on this subject. Cheers

Hi, what do you think of the colour scheme. Just got it yesterday, cost next to nothing, is it a good project? http://s810.photobucket.com/albums/zz27/my...before%20start/ Myson
