    Cracked Airbox

    My airbox broke away at the 3 front holes of the airbox,I brought the airbox hose round fixing plate from bultaco [uk],I fitted it too the inside of the airbox hose aperture and glued the broken parts into the 3 holes, I then screwed the two plates together which made a very strong joint,I also fitted two rubber washers under the bolts to separate the airbox from the frame to stop any vibration which i think may have caused it to split Hightown
  12. i have a bultaco 198a 250cc it will start with the choke on from cold after two or three kicks, after it has warmed up if i stop to look at a section for four or five minutes i have to use the choke again for it to start, is there anything i can adjust it to start without the choke. Thanking you in advance hightown .
  13. Hello Charlie When starting a bultaco 198a from cold fitted with a amal mk2 carburetter with the choke on should you keep the throttle fully closed or a little open. Thanking you in advance Hightown
