Billym247 Posted July 12, 2011 Share Posted July 12, 2011 hello, yes you could start by upgrading the air filter, performance exhaust, and maybe put better reed valves on, think that's about it if you don't want a bigger engine displacement upgrade, Thanks.

Its a fours stroke engine billy, so no reed valves here. Link to comment Share on other sites More sharing options...
