      Get keihin jets get them in different sizes varying from 135 to 145 and pilot jets of size 40 to 42. Stock jets of Karizma are 125.5 mains and 35 pilot. get them from Jets R Us

      If at all you need more performance try eliminator's 31mm cv carb, its hard to find but nothing impossible you can trace it out in any of the junkyards.
      i heard a new one will cost you more than 8k !!

      Still better option try BS29cv carburettor which joel is running on his fiero 200.

      Which filter you are trying to plonk in after upjetting

        DO we need to do any mods before installing/upgrading to new jets.
        are there any tuning manuls?
