  1. In most european countries the 95 octan fuel contains 5% alcohol (ethanol) so changing from 98 octan to 95 octan means that the bike will run slightly leaner.

    The E85 fuel is 85% ethanlol and demands a radical rejetting. 15% petrol is needed for proper coldstarting at low temperatures (less then -10C).

  2. THat Dellorto is sounding more and more interesting Carl..........I see the one in the picture is an  R9359, and you give your jetting info for an R9354.........is there any difference?

    R9354 is the number if you buy a std carb from a Dellorto dealer. I guess that R9359 is a specific Beta jetting for Beta Motors which should be very similar to mine.

  3. VHST 26BD R9354 basic jetting for Beta 250/270

    main jet: 120

    idle jet: S37

    needle jet: 272H

    needle: D47

    throttle cut away: 50

    choke jet: 60 ( I feel that this may be a little bit lean)

  4. Dellorto VHST 26 BD fits stright in and is an excellent carb. More power, no dribbling, no pinging, instant throttle response and a soft throttle spring. Beta use it on the 125
