Default sikk timing on a zenoah

hallo guys. i am running a 25.4 sikk motor and are happy with its performance buttt i had my off days[:@] due to some failure issues. i bought my self a standard zenoah and want to start toggel it a bitt . how much performance should i get if i do coppy the timing from the sikk and cut the zenoah the same. we do figure m coarse racing and i do need a motor with good throttel response. if i go with exhaust 178*and the inlet 155* what hp rating should i have. any suggetions is welcome.

Don't copy the CY, the Zenoah will not like an exhaust port done that way !!
* Do use the link provided [:@] ..... You will be quite happy with the results
