  1. You may try without one shaft each time, to find out where problem is located.
  2. I guess your gearbox is OK. I think it´s the selector mechanism. To examine it, as far as I can remember, you´ll have to remove the clutch basket.
  3. It looks the Finnish flag blue is Pantone 294C which seems to be little more blue then RAL 5015 so correct shade of blue looks to be 294C for 199B and RAL 5015 for 199A
  4. Had a discussion with a number of Bultaco experts some time ago about possible shades of Bultaco blue. It ended "there is only one known Bultaco blue from factory". Different shades of blue seen on old colour photos is possibly due to agening photos. This is good for me unless someone has different and more correct information. My remark is RAL5015 suits well (or perfect) and it´s easy to find https://www.ctborracha.com/wp-content/uploads/2019/02/3-RAL-to-Pantone-Conversion.pdf
  5. Agree👍 They are surprisingly durable. A replacement is not the first thing I would look for. Go for the Domino and as said previously, do not overtighten the bolts.

  7. https://www.splatshop.co.uk/s3-hardrock-steel-footrests.html You may find similar from Jitsie
  8. Think you need weld on brackets for the footpegs in mention. Most people feel comfortable if they move the footpegs slightly rearwards and slightly downwards. Slightly is up to a couple of cm. I like the S3 steel ones. S3 steel footpegs are reasonable light and are long lasting
  9. https://en.wikipedia.org/wiki/High-density_polyethylene "HDPE is resistant to many different solvents, so it cannot be glued. Pipe joints must be made by welding"
  10. 199A head steady is not a good design. Mine has been broken for at least one year now. Seems to work well nevertheless. Best is of course to loosen all necessary bolts and retighten to avoid extra strain after assembly. For my 199B I have made a new and better design but not tested yet.
  11. As far as I know, usually no major problem with PWK. Splatshop are good at carbs and have spares,,jets etc https://www.splatshop.co.uk/performance-parts/keihin-pwk-spares.html
  12. Also check you don´t have an air leak.
  13. It might be residues from air filter spray that follows the airstream into idle system and get stuck. It is not dissolved in clean petrol. Some people use Carb-Cleaner to dissolve. Have no experience of that liquid. When blowing, should use well filtrated HP-air. The passages are very small in the idling system so it can be difficult to clean. It happens it is a nightmare. Perhaps you should concentrate on cleaning the carb body and buy a new jet. As jets can be dirty from factory it is best to have it ultrasonic cleaned before assembly. For safety´s sake, HP-blow the jet after the Ultrasonic cleaning. Is it a Dellorto VHST or Kehin PWK? My last carb-cleaning-nightmare was approx 8-10 years ago with a Mikuni (original) on a Beta evo 4t. Eventually a man (not me) fixed it.
  14. To me it sounds like you have a problem with dirt in idling system. Not easy to clean. Must take everything out from carb and carefully blow and clean. Remember to blow and clean all drillings and passages in carb body. After only use a good, clean and oiled airfilter and change often. As I see it, dirt in idling system is one of the most common problem in a dirt bike. If problem is only at certain throttle openings I would say it isn´t the ignition. Ignition problems is most often at all throttle settings.
  15. Accordingly to this list https://cemoto.tripod.com/list.html 199B started in May 1981 and ended ? Numbers should be 12876-14653. It is unclear when production ceased. Some sourses say in 1983. Rumours say the workforce assembled the last bikes from remaining parts https://cemoto.tripod.com/photos/blue.jpg
