it appears (from google search) to be around a 1970 Metralla 250cc 2 stroke 5spd. its a one owner 3100 miler. been sitting in a friend of his shed for over 20 years.  kicks over, shifts, and he rode it to where its been parked all these years. he has a title for it and the original (spanish) owners manual, which he said he will get to me once he gets a chance to find them in his file cabinet. this thing is frickn sweet! he showed up here at the shop with it. came up to me and asked if i had any use for an old bike he didnt have a place for. hmmm ummm well... then he said a bultaco... huh?! really?! lets go look at this thing! now here it sits  anyone know much about these things? | ||

Made in Spain. (unless I'm mistaken about that) That's all I know about it. Oh yeah - I think there's dirt bikes by them, too! That's a really nice score - have fun with it! Al | ||

Great bike, It would work well in my garage! They were a super fast and well handling bike in its day. Materalla won the Island of Man race . | ||

yeah, i know a little about them, but mostly that dirt bikes were there big thing. from what ive always heard they were actually kind of a force to be recond with at the races. | ||

I had a 250 Sherpa of theirs (many moons ago) Great bikes, fast & reliable for their time and fairly easy to work on. getting parts could be a bit of a challenge but parts are readily available for a host of long defunct bikes, so the search could be a lot of fun. Nice find! Chris C | ||

I tried to PM you about the bike. For some it didn't go through. I would like to talk to about it. | ||

Great bikes, original Bing carb pain in the rear to tune. Fun when they run, just seeing it brought back the smells of castor(bean) oil, dang I loved my Pursang, scary fast... | ||

I suggest you only clean it up and resist the temptation to paint anything. Original is best. | ||

 Picture is the front of a reproduction sales brochure. Also still have a parts book#23.32-117. | ||

i really dont plan on painting it. maybe fix the chrome bars and exhaust if i can but keep the original stuff as much as i can. find the couple missing decals. and im assuming you must have had one James? only reason i can think to have a parts book, lol. | ||

>>you must have had one James? Here's mine,traded back to my older brother for the X1 about 5 years ago. It was a 100 point restoration. Fun as hell to ride.  Also 3 Sherpa S's 2 Pursang's and a Bandito Might have a pic of my Pursang/Astro. (Message edited by Jramsey on May 19, 2011) | ||

The worst crash I have ever had involved a 250 Pursang, a clay oval and a 8ft high 3/8" thick plywood fence...it hurt for a long, long time....I still limp in really cold weather. | ||

At one time they were BOSS of dirt. | ||

Beautiful! Nicer than my 71 Kawasaki F8 (250cc). Our own Steve Natt had a nice interview with some Bultaco faithful. I think you can get all the parts you need, but they might not be cheap. | ||

1972 I was 15 at the time, start of my second season on it. I'm only 5'3" in the pic, lol. "70 Mk-IV Pursang,5 port Astro liner in a round barrel jug,George Banke pipe.  Still have the K&N spool front wheel and my Maeley steel shoe hanging on the wall. | ||

If the Bultaco is a 5 peed it Metralla Mk2 with a shift pattern of 1 up and 5 down. A very fast bike for the day. It should a Amal carb. | ||
| Jramsey |
>>>shift pattern of 1 up and 5 down. 1 up 4 down, frame mounted shifter on the 5 speeds. Lever has a dog on the inside that fits into a fork on the end of the shift shaft. The dog was eccentric adjustable to compensate for wear. Rices bike appears to be a late 4 speed possibly early 5, note the different primary cases. | ||
| No_rice |
it does have the amal carb. i guess i havent checked(still at work) enough to see weather its a 4 or 5 speed. i just checked to see if it would even change gears and it did. | ||

Quote from a short tracker I used to hang out with back in the '70's: "There's nothing older than an old Bultaco!" But I remember the guys with the Amal monoblocks pushing their bikes around in circles to start them because the float bowls were offset to the side. Damn, I'm old! rt | ||
| Lemonchili_x1 |
That is waaaaaaay cool Tim. I don't know much about them, but I had tried to track one down when I was younger just because they were a 250 that was different. | ||

"But I remember the guys with the Amal monoblocks pushing their bikes around in circles to start them because the float bowls were offset to the side." Bultaco IIRC went to concentrics about '66.. the first year they won the Isle of Man running the 250 in the 350 class. The twin plug Femsatronic ingition helped a bunch along with a compression release. Rt, if you look close at the pic of my half miler you can see a 36 mm Mikuni mounted on a steep angled custom intake manifold. | ||

I may have to push it! I've got damn good spark. Even misting a little fuel into the carb I haven't gotten it to pop off. Probably just not kicking this thing fast enough. Gotta take out the petcock too. I've got the valve taken somewhat apart and still no fuel comes out. Although the tank will need a good cleaning out. A little rusty. Looks like fine surface rust. Clean it and probably coat it inside I guess... | ||
| Two_seasons |
This thread sure brings back memories. Look at all that suspension! The tank will give you a lot of trouble if not cleaned up and coated. Lots of crud stuck in there that several tanks of fuel will dislodge and put into your tap/filter. It will be like paste at times. Nice find and I'd do little to it like you said NR. | ||

I have woken up a good many old two-strokes (All lawn care things) The thing that helps you start it the first time is oil. You need to establish a good seal in there in order for it to pull in a mixture. Dribble some engine oil in the spark plug hole and crank it over a few times to establish a good seal. I think those things are piston-port induction so there aren't any reed valves to be stuck. The crank case seals might be leaky due to being dry all this time too. Bear in mind, all of these tips come from waking up old lawnboys and chainsaws that have been sitting for a few years so that the advice with a grain of salt | ||

Nice. Check the Old School forum at advrider; you can probably find some other Bultaco projects there. | ||

My 71 bison had seals that, incredibly, looked almost new. The exposed stuff was shot (foot pegs, hand grips) but once you got inside the motor things looked new. The oil injection system was bad also, all the lines there were full of hardened and rancid castor oil. All in all though, it came back great and runs amazingly strong. Those 250 two strokes back in the day were heavy, had crappy suspension, and lousy brakes... but they weren't hurting in the motor department. |
