Bought this recently. It's a GSF250V. Another inline 4 cyl 250cc. I love how they all have their own quirks or designs.
The bandit in particular has the same VC-engine (variable lift on the inlet cam) as its larger brothers.
Trouble is, it was only officially imported for a few years here in Australia - 1999 and 2000. No service manual available on the net. Japanese hardcopies available to buy. I actually work for a suzuki dealer here so I will have to make equiries. Had a brief look at suzuki's online manuals but it only has newer models.
