guys i need help fast,the blaster when you give it throttle it bogs to hell but idles fine so when im looking i found that my exhaust is leaking right where the silencer and pipe meet. I sealed it with the rubber thingy the stock exhaust have but still it leaks, any ideas how to seal it up?? Also anything else that could make it bog to hell when i give throttle other than jetting, cuz i have it jetted right and cleaned carb too.
