  1. Try to get a copy of this book https://books.google.com.au/books/about/Bultaco_Limited_Edition_Extra_1971_1979.html?id=FZdVAAAACAAJ&redir_esc=y&hl=en there is a cycle world test of the m187/188 that they claim the only difference to the m165/166 is the paint scheme. Has a good spec list of it. there is a few other Alpina tests in the book from the day
  2. You'd be better off asking about model number differences like m138 years don't really identify Bultacos ive never seen individual Haynes manuals your probably after Bultaco parts books here's a m212/3 link to one http://www.custgp.com/a1manual2/Bultaco Alpina.pdf
  3. Woody I'm pretty sure all the 325's from m125 on had the same flywheels around 2.8 kg on both sides your 159 may have been modified if it had a pursang primary flywheel
  4. If your talking about ignition side you might not want a m49 ( VAR41-9)flywheel about 2.4kg against 2.8kg that you probably have now (VAR41-52)) where as the 250 later flywheels (VAR41-51) m124 on are around 1.7kg. Well that's from my scales they probably vary a little bit. A lot of 250/350 Alpinas (m137 on I think) had the VAR41-51 flywheels so it might be easier to find one from a Alpina as there seems to be a fair amount of Alpina parts on eBay in the states.
  5. Part no.49.00-068 for frame no. up to 1832/ part no.80.00.068 for frame no. 1833 onwards
  6. Ah that what it is a Y not a V thanks Bought some once when I couldn't get a S in town didn't notice any difference in the running though
  7. Doesn't the V on the bp5ev spark plug just mean a v'ed out electrode
  8. Yes they are the models I call Soler as wellThe later models are nice bikes but the earlier models up to and including the Soler models were a piece of art in my opinion
  9. I suppose you could say that Paco is Bultaco Nothing really special happened after the Soler Sherpas in my opinion
  10. I've also been using IRC tubed (49,125) and tubeless (183) with no problems on my Bultacos
  11. Most have probably read this but it's a good read like the rest of the site. http://www.retrotrials.com/exclusive-ignacio-bulto-interview-20122.html In my opinion the last true Bultaco would be when Paco still had control of the company
  12. All the steel bottom yokes I have including M49 are M8 x 35 mm x 1.25 thread hex head
  13. I've got one on a m183 it runs really well, the jetting should be close on a 158 Main 103 Pilot 33 Needle d36 clip in the middle Needle jet 266k Slide I'm not sure no markings that I can see but I think it's a 60
  14. Banana, fork caps, wipers, carby, levers, ......... Nice bike but how about a photo of your 69 one
  15. What's been done apart from the 74mm gasgas piston to make it a 280 has the crank been altered ?
