Hi Shakennstirred thank you for the tips i have ordered the spark plug, I have some rear shocks which are 360mm which i will try first hopefully they will be ok, Your bike looks better than new and I really like the works colours on you bike.

I was looking for some help please.... Im rebuilding a 1981 Black engine 250 Beamish Suzuki and would like to know what size rear shocks ( how long in cm or inches please ) are been fitted to your bikes and which spark plugs seem to work best ? Thanks for any feed back.

I will be using the new full size copper head gasket for the 250 from the Beamish owner club. In stead of the standard ring gasket, thanks for any feed back

I have been look on Gasket guru for a new cylinder base gasket for my Black engine 250 which is the standard thickness gasket please

Im Rebuilding a black engine Beamish Suzuki and i was trying to work out the best way to clean up the fork legs, has any one got any tips please on the best way to clean them so the look a bit better ?

Hi feetupfun thats the one that Scot Taco and Model80 are talking about, i think the photo in Model80s link shows the fiberglass cover and a bit of the alloy inner tank, it looked ok to me. and Inmotion are nice people to deal with and almost every thing i have ordered arrives the next day.

The boys that have an Add for there great internet shop at the top of this page have a new tank in that style for sale looks good. It has fiberglass cover over a aluminium tank, i was looking at one they had on there stand at the Telford bike show.

Hi Trialsfun My bike came with the 159 airbox so Im not sure if it makes a difference, I was told they are sort after so not cheep ! unless you have a lucky find, but if your bike runs well i would keep it the way it is. I think i use about 10 % of what my bike is capable of ........... But i am working on that BR

My Bike ran well with the Mikuni i was told it was from the 70s ....... But like i said it ran well. Thats the set up i run with the 199B style air fillter, yes my bash plate is from Todotrials easy to order you can email them in English ( nice and friendly to deal with ) they send you bank info ( its in a big city so i needed to search for the right branch ) and you just send them the money and it arrives in just over a week, i got a good tip of Ibhbul who makes lots of great posts on here fit a piece of rubber between crank cases and the bash plate. BR

I could never really decide how to set up the bars in clamps on the standard top yokes and i wanted to make the steering feel a bit quicker and feel like it wanted to turn ! i got my rear shocks a bit longer and fitted a michelin front tyre then spotted this top Yoke thinking every little bit helps and for me its feels better. But the best things i have fitted and the things i noticed the most were a new IRC rear tyre and the new style big flat alloy foot rests

Hi Trialsfun The top yoke is really well made, i spotted it being talked about on facebook by some Bultaco riders its made by Gerry Minshall, he had a set at Telford on the Twinshock Trials Championship stand so i could have a good look at it before i spent my money. He has some photos on his facebook page under albums / mobile uploads. BR

I got a chance to get out on my bike at the start of the spring i had fitted some new style foot rest a bit lower and back a bit and i really like the way they feel so much wider to me they are so much easier to stand on, they are the big alloy new style ones my bike had had the original foot pegs moved up and back so moving them down and back a bit was quite a difference. i also fitted some new Domino levers which i find easier to reach. looking forwards to seeing photos of your bikes as you rebuilds progress. BR

Hello Model80 I have a 199A it came with an old Mikuni and the older style air box off a 159 which is bigger and helps the engine breath i also replaced the old Mikuni because it would flood if engine was not running. Every one that has a go say how smooth and soft it runs at the bottom which make easy for me to hold on to, till its about 1/2 open then its still smooth but getting really strong and mean........... But a lot of fun I forgot to say i fitted a Dellorto PHBH28BS ! and a Billit Parts adapter so it fits to the air filter rubber hose

As you can see i have had a bit of time off work, im not good at sitting still ...... So have been doing some jobs on my bike and over thinking...... I took the head off to have a look every thing seems nice and tight ( my friends words ) The marking on the top say T2-- is this to do with size of the piston I have a low number 199A did the first ones have the gear box drain plug on the bottom it has the small almost flush one not the big 199 style one ( way too much time on my hands )

When i first started riding my Blue Bultaco 199A in trials i was having trouble with the chain jamming full of mud in the rear sprocket lots of mud and sand were i ride. i did not really understand why it was happening so i posted on here and got good feed back and a great tip from Woody on how the rear tyre can feed mud on to the bottom run of the chain into the rear sprocket, the sand and small stones mixed in the mud did not help at all. So i cut the lid of a soft plastic box up to make a flexible bottom bit for my chain guard to try and stop the mud getting onto the bottom run of the chain. When i had finished fitting it i was thinking thats going to last 5 minuets ...... before it gets ripped off and lost. i counter sunk the heads of the nuts on the tyre side so they would catch the tyre or hold onto mud, i used small nuts and big washers to try to keep them out of the way of the chain and the tyre. Well after 3 trials its still hanging in there ...... and after the first trial in the sandy quarry the chain was still nice and clean at the end of the event which was a first for me.

I had a go at cutting open repacking my exhaust with the help of a friend, I had the luck of bumping into one of Bultaco top works riders and he told me how he repacked his which was a really big help in making sure we had a good chance in doing a nice job of it. we cut it open and pulled all the old packing out which was all gummed up then got a blow torch on it and burnt all the crap out of it till it all looked clean then repacked it nice and tight. BR

HI Scot Thats the best one i have seen made to measure and a prefect fit, My bike came with a home made one, no were near as good as the one you have made, but i managed to brake it ! So i managed to find a Bultaco original left hand rear brake peddle from an earlier Sherpa and was so excited ( photo attached of one like i found ) but the arm is not long enough to clear the top of the swinging arm on my 199A and give a straight line to the rear hub brake arm ........ So the one that came with my bike and fits and lines up with the rear brake is being fixed. Scot please keep posting photos of your work on your bikes, looks like you have lots of great bikes to have fun on. I also have a big grin on my face when im riding my 199A the grin gets even bigger as i open it up. I have just had the rear box stripped and rebuilt simular to the way the spanish Bultaco tuners do to there bikes a friend of a friend did it for me, he said it was so full of crap he was surprised it worked at all, so i guess it needed doing. All the best Joe

Hi Scott, thanks for posting some photos, Your brake pedal looks better than most of the ones i have seen for sale. All the best Joe

Hi Billybob, I fitted a new head set, asked an old biker friend how he would do it he said put the bottom of the yokes with the bottom part off the old head set in the deep freezer over night get a barbecue hand held gas lighter the one with the little flame and warm just the bearing up then face it down and tap the end on a bit of wood till it falls off ..... i needed to tap it quite a bit to get it moving but it came off then and the old cover ( lose fit ) came off to, i put the yokes back in the freezer, later heated a new cover ( tight fit ) and the part of the bearing on the gas cooker and they just dropped on i could not believe my luck ! Got my head set off Stu feel really smooth. BR

I have had a little go on a really nicely setup 199B it was great to ride, the things that really stud out to me was how well it steered and how good new style wide foot pegs felt when set in the right place, my bike came with foot pegs which had been moved up and back not sure why. Anyway i got a set of Gerrys top yokes and dropped the fork legs all the way through the top yokes and that seem to have done the job for me. I made all the tight turns at the last event apart from a steep decent in sand with a tight turn just before the bottom which had me feet down trying to pull it round every time ....... May be a bit more work on the rider will help ! What i really like about my bike is Bultaco designed its engine to be smooth all the way and to really rev out cleanly more so than the other Sherpas, ( read this in a bike test ) never fails to make me smile as it start to howl i get some arm pump trying to hold on to it some times. Its been a long time since i had a SWM but i do have my eye on one again, it was really nice to ride and easy to ride, my friend had got him self a bran new white 349 Montesa after a while he asked would i like a go on his super new bike i liked the SWM much more and so did he ! he even said some thing like thats cheating to be fair his bike needed to be setup much better. The only thing is i always seemed to get into trouble on my SWM falling off crashing it would catch me out, it just felt a bit more nervous may be ..... than my Bultacos did, I have always like maximum stability first i need it i have trouble concentrating for more that a few minuets at a time and the extra stability seem to keeps me out of trouble. I love this forum BR

Hi Scot The air box came from a 1975 model i think this is one of the best looking bikes they made, they use this air box on quite a few models so there must be lots in the U.S.A . the inside volume is bigger so helps the 325 engine breath better most of the works rider put this air box on there bikes. i was lucky it came on my bike. The top yoke i had seen on the web so went to pick one up at the main show here but he had sold out big order from spain ! but had one to show are take orders they cost 150 pounds and its so well made that i would say it could possibly be the strongest part on the bike ! in the box with it came a top cup that fit on the top of the steer a tube CNC and a CNC top cup for the head bearing race, i will try and find a link and pm it to you. I think for me the biggest difference was fitting new style foot begs the big wide and flat alloy ones, they are lower in hight the way they are made i moved them back and a bit lower there is not much room they are still cover by the frame so much better to stand on nice and wide. All the best BR

Hi Scot i think we have the same bike 199A, in the late 70s i had a new 198 which i really liked. I passed my road bike test so i could ride any cc bike from then on so got my self a beamish suzuki 325 nice bike but missed my Bultaco sold the Beamish the same time a friend was selling a really well setup SWM and it went really well much better than any bike i had had before so much grip it held a line really well engine was really smooth it was not me it was the bike it would drag me any were i pointed it, But i think my Bultaco i have now with all the little jobs im getting done on it, its becoming more than a match for that SWM i use to have, I think the Bultaco 325 199A engine we have in our bikes is just magic. Anyway here is some photos from my last event. i think we have the best Bike .......

Hello Ibhbul I have zoomed in and made it a bigger size so you can have a better look, looks like a BSA bantam engine to me. There are some really nicely set up bantams over here you should be able to find out more on the Pre 65 part of the forum All the best BR
