Awk08 is absolutely correct. Yamaha de-tuned the hell out of the blaster to tame it for
'New" inexperienced riders, plus gave us tuners the ability to open up things and make them work better. Take for example that rubber snorkel on the air cleaner lid. You can't even get your thumb in the opening. That is the first thing you remove, then check jetting. The snorkel on the banshee is worse.
