Vilder racing tops / SRX - usable for viper ?

[Yamaha Norway]

Anyone has any information about these SRX tops ? Ive been told that they have smaller chamers, that`s all. hp gain ?

Are they usable for a SX Viper ?

A lot of people drive vipers with modified srx tops.
How are these in conjunction ? Any ideas ?

they will work on a viper with a water rail, either home made or from megapower, peak or someone else.
for a viper, you want the domes to be around 23-24cc for trail riding assuming pipes.
