A: Something in the area of 95 pump octane. Your best bet is to make a 2:5 to 1 blend of 91 premium and VP MS109. It equals out to a perfect 95 for around $6.00-$8.00 a gallon depending on your local area prices. It's always a good idea to retune your ECU fuel map when installing higher performance aftermarket parts to avoid possible engine damage.

A: It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

A: The standard compression for your 2007 Yamaha YFZ450 would be 11.4:1. This Wiseco Pro-Lite High-Compression 4-Stroke Piston would be 12.4:1.
