Looking for a little guidance with some exhaust popping. Just picked up a 99 EV California with 7900 miles on it. It has the original exhaust and upgraded crossover from Harpers. It was initially popping on decel mostly from the right side pipe - and I thought maybe I had a bad baffle - but I just had the bike serviced - to include balancing the throttle bodies - valve adjustment, etc. Now it pops from both sides. Exhaust connections appear tight. Does not have a power commander. Any suggestions? yeah, yeah, I know...get the power commander. I might, but want to ensure it is running properly before I do that. Any help appreciated!
