There are some changes that are being made and the new website doesn't have everything on it yet.
The previous YS Performance website is no longer in service.

There will be more and more as the next few weeks unfold. One thing that is on the radar now is getting a set of instructions on running the YS engines. For now you can get the manuals for all the current engines.
These manuals include running instructions. The basic principles on running the engines and setting them up is the same on all the engines. There are differences like on the Dingo motors compared to the pressurized motors, but most of the adjustments and so on do the same things and work the same way. The big difference is the DZ style motors
