POWERVALVES
Suzuki’s powervalve system (Automatic Exhaust Timing Control) uses ‘guillotine’ blades to open and close the exhaust ports. The three-stage system on the VJ22 saw an increase in complexity and parts, and the maintenance and set up of these systems became more problematic. Issues can end up with a catastrophic failure and associated rebuild costs. So check with the owner you’re buying from as to what work has happened and when. Regular maintenance is key here and more robust valves are now available which helps.
SUSPENSION
VJ22s had more developed suspension over previous models. In came a fully adjustable shock and 41mm inverted forks with pre-load adjustment. SP models had fully adjustable front and rear. By now, all suspension would need a good rework. Thankfully, as these were popular racers, there are plenty of places that can advise on the perfect suspension parts/set up.
