Put unbaffled fishtails on. Popping issues. Upgraded to Mikuni carb & put washer in pipes to break up reversion. Popping still remains, especially if its hot outside. Now looking at true duals with minimally baffled sharktails. I also want to up the performance - planning to go with cam upgrade. Any thoughts on best "bang for the buck" for performance upgrade + eliminate popping? I don't want to lose the look. I do have some baffled fishtails I took off - I may put them back on.
