Speed costs $$$ also you need the speed to be used right because if it is stop n go you want more bottom end, if you have no stops, traffic or hills it is totally different... also depends on laden weight of bike and gearing... I share 3 known to be reliable and streetable event timing recipies so you can get some performance but also be able to tune some idle and be able to run all day long and into the night. There are more aggressive recipes but there are compromises so I just suggest this as good for a beginning, you can judge your own abilities to tune.
If you are running a CDI then set the timing for 1,2 btdc rather than 1,5 and let the pipe do the work for you and keep the heat out of the motor.
For general use (traffic n such) getting up in the 30s mph
Exhaust - 145 degrees Transfers - 100 degrees Intake - 130 degrees spark 1,5mm.
Nice derestricted circuit pipe and SHA15:15 with derestricted Malossi 15mm intake and match port the unions.
Based on the C & D series Mobys, this is a good timing event recipe
Exhaust 150 degrees Transfer 104 degrees Intake 124 degree Spark 1,5mm
Same exahuse, intake and carb will give you 2,5hp at the pto so goodly for all day long traffic and upper 30s or better.
Based on the 72020 cylinder used on the Speciales
Exhaust 160 degree Transfer 110 degree Intake 120 degree Spark 1,5mm
Same exahuse, intake and carb will give you 2,8hp with long power band can give you 40s.
