I just got done specing out and modding my xsc. here are some of the stock port timing numbers I pulled yesterday
Rampage xsc
bore 36mm
stroke 28mm (measured several times)
displacement 28.5cc
exhaust port timing 153
transfers 109
intake 143
Here are some numbers from a zenoah 23orc if any of you care to play around
exhaust port 170
transfers 125
intake 145
these were the best numbers I could figger. The small size of the motor makes it pretty difficult
