Bultaco

So the road to Robregordo starts here and now. Dug the old 199b out and started to begin fettling ready for Robregordo next year. Now as previously mentioned somebody in the dim and distant past fitted an Amal Mk2 to her and i've never liked the running with it fitted. So going to fit a new carb but which? Ruled out the Bing as too many people say it's crap. The Mikuni or the Dellorto seems the way to go. A lot of the Spanish lads had them fitted i noticed at Robregordo this year then again i've also heard good reports about the Mikuni. I had one fitted to a Bultaco a long long time ago and seem to remember it worked well. They are both roughly the same price so what is…

Just looking at the MOT regs and it says that bikes first used after the 1st Jan 1973 must have horns which are not of bulb type. Do many testers notice this or can I get away with it? If not, how would I wire in a horn to the wiring? The bike in question is a Model 124 with the standard Femsa igntion with the Red wire replaced by Black (other wires as standard) and I don't normally use a chocolate block in the wiring systems. Another question is how do tester react to slightly bent wheels (luckily I have a good set )

Hi Ive just dragged all the bits and pieces together to start the rebuild of my 199a BUT! The frames been shot blasted and primed and is ready for spraying! i could do this weve spray cans (ford electric blue!) or pay for it to be done in 2 pack or find someone to powder coat it in the correct blue this is where i came unstuck last time as the powder coater i use didnt have the correct blue (i didnt know the correct code?) so it was sprayed in primer and left until now! also ive got a original seatcover for it but what a job to fit it on as the seats banana shaped i cant seem to get rid of the crease in the middle?( the seat foams good!) any tips on this? also any…

Took this at the Scottish and I guess our new Media Star, Professor Moffat, would go in the huff if no one puts it up on here....... ...mind you it is gorgeous

Hi Chaps! my mates just got hold of a 325 post sherpa, its fitted with the gearchange on the leftside(when sitting on bike) when you kickstart the bike it goes into gear! ,someone said this is normal as this is because the aftermarket gearlevers are not the same shape as the original one? is this correct?

Hello! I'm restaurating a Sherpa 199B. The betor shock absorbers are completly damaged. So i have to look for new one. The length of the original betors are mounted on my bike is 345mm. I have found pretty shocks on web called BBS-competition. But they only available in 340mm or 360mm length. What do you think is better 340mm or 360mm? Dose the 360mm shocks fit the 199B? Have any classic-freaks experience with the BBS-competition? Thanks for your answer!

Hi, Bought a 350 Sherpa to restore, but a change of job means I won't have the time. Can anyone recommend someone who restores old bikes (apart from the obvious dealers), preferably in the Midlands area? Cheers,

Ok, guys ive now installed a new ign side crank seal, im sure the clutch side seal should be ok as 1, the bike dosen't smoke excess, 2, the bike starts 1st or 2nd kick! BUT ive still got a problem with the lower end of the rev range! the bike idles for a very short while then dies! but the revs dont pick up well as in you have to throttle it lts to keep the revs up and stop it from dying! and have to give it loads of revs to pull away! the mid and top ends good and it will really get a move on when needed! ive cleaned out the carb , jets etc! the vent pipe on the tank clear, new s/plugs gapped and fitted! fresh petrol added! the timings not been checked as …

Now i know there has been a bit of talk on here about different carbs etc. Well my 199b has a Mk2 amal fitted instead of the std Bing and as i am trying to get it sorted with a view to using it in twinshock trials then i was wondering about the carb. Rang Bultaco UK today and asked about the bing they show on their website but they havent got any in and have to order from Germany plus were not sure of the price but said it would be more than on the website. So what do i do ? Anybody had any experience of using alternative carbs on 340 Bultacos? Dont mind spending money but havent got a lot left after the James build so need to spend it wisely. To my mind the options a…

Hi guy's, i have been on the dreaded ebay again and got a real nice T250 (1978) http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...p;rd=1&rd=1 but 3 of the front wheel spokes are broken so where can i get a few spokes and nipples (10 inch ones ) besides bultacouk.com as they only seem to sell them in sets? Also what colour should the frame on a 198 model should be ? as this one has a nice dark blue colour but i thought it should be black! thanks Dave

For gawwds sakes buy another bike. We need a decent thread here.

All this talk of Twinshocks has got me thinking about using the old Bultaco again so as i cant do much with the James till next week thought i would drag the old girl out and get her up and running again. After a bit of faffing about draining fuel and cleaning the carb got her running. Now to get her Trial ready. So some advice required please. Its a model 199B 340 81 Sherpa What is the std gearing? It's just that it feels a bit high geared. It's got knackered rear shocks so they need replacing. Will probably go for Betors but the ones on it are 360mm center to center. Is this right? Looks a bit high at the back. Steers ok but seem to remember 340mm was the length fo…

Having problems with my slimline bultaco! at first the carb wouldn't flood (tickle) to start her so ive stripped the carb down and cleaned through all jets/pipes etc! got the carb to flood( the bowl gasket was badly cut and wouldn't allow the float to rise properly!) now got the bike running but theres petrol rising up and coming through the button you push down to flood the carb with, So the float height wrong somehow and allowing the petrol to rise to high? ive had the carb on/off umpteen times and are now starting to get p*****d off trying to set it up correctly its an amal 627 bolt on type! ive set the airscrew 1 1/2 turns out from fully closed as far as i know t…

Can anybody help who has experience of Bultacos ? I understand that the Pursang fork springs are about 40mm longer than the Sherpa ones? are they the same spring rate? When i went to Malvern i noticed a couple of vendors selling "progressive rate" springs for Bultacos 35mm forks. Has anybody used them? Are they any good? Are they better than the std springs? Reason for asking is that i am trying to sort out the front forks on the James project. The Marzocci internals that Alan Whitton put into Norton outers for me feel a bit "oversprung" and after measureing the springs, there are two springs a short one and a longer one in each leg, they in total are about the same le…

Hi all Can anyone help me with any photo's to help me see whats there or not as i'm trying to sort one out for a friend. He reconds it's got a miller tank cos he has just got a new cap for it (

I know how you love Bultacos BJ so have you seen Vestys 82 Bultaco for sale on www.willbrown.co.uk/adz ? I havent got any spare cash at the moment but you might be interested ? Hope i havent transgressed by posting this if i have i appologise Andy.

As i stated in another post hopefully in the not too distant future i will be getting round to doing the Sherpa up. Shes a 199B a bit tatty in a well used kind of way but just paint and decals as everything works and it's all there. Well looking around the Bultaco stand at the Classic off road show on Saturday i was wondering about "modifying" the swing arm and mounting to make it more like the works bikes or do i just leave it original? http://i4.photobucket.com/albums/y117/NVT160/DSCF0053.jpg http://i4.photobucket.com/albums/y117/NVT160/DSCF0052.jpg Was thinking of riding it in some twinshock events next year. I know it will be outclassed but i do like riding the old…

Ok guys I've taken the plunge and bought a early bultaco, as far as I know its a 71 (k reg) but it needs setting up correctly, it starts but its woolly! as in the revs are all over the place! It seems like air is entering somewhere. The inlet manifold rubber and the airfilter hose has got some splits in them? so these will need replacing for a start! An amal carb 627 type L428 is fitted and looks quite a new one! Is this the correct carb? whats the correct spark plug and ign timing? Also I've included some pics as the front brake is much bigger than standard it looks like a mk1 cota front wheel? what do you think? I've had a m80 front wheel in the garage for ages (lu…

Hi Can anyone tell me if the carb on my 78 350 should be an Amal with a flat plate choke lever and if it is should the gap between the airbox and carb be very small? Cheers
