My experience with the 91FX is as follows. This engine is timed for "Sport" use. The exhaust port timing on this engine is very sedate at Aprox' 145 Degrees. It is exceptionally hard to get this engine to work on pipe correctly. You really need an exhaust port timing of around 155 Degrees to get it to work well.
Your best bet is to run an APC 13 x 10 with 10% Nitro. This will Tach at around 9100.
