billyt Posted April 7, 2014 Report Share Posted April 7, 2014 All depends on what bike! There is no mention of what bike you have. Quote Link to comment Share on other sites More sharing options...
bullylover Posted April 7, 2014 Report Share Posted April 7, 2014 Hi Bondy. I`d give In Motion a ring and ask them as they sell Mikuni`s for Bultaco`s. For those who don`t know a M 198 A is a 1979ish 250 Sherpa T. These were the all blue ones with black fork bottoms and the first ones with no frame tubes under the engine. Over here they were the 1979 model and the last ones to come over to Australia. We didn`t get the M 199/8 B`s. All of the ones over here were imported privately.
