R&Ds personal water craft tuner Bill Chapin uses a set of gauges in order to monitor the conditions and fine tune the engine of the Ultra 250X or any other four stroke engine. The particular set comprises of three gauges, in order to check air/fuel ratio, boost pressure and air pressure. All three gauges are fit on a panel that is positioned to the glove box. R&D will soon make this gauge kit available in the market. It guides you easier to the set up of the Power Shot that plays key role to the performance of the four stroke crafts.
