ok. i got a new HT kit, so i took my old one off of my schwinn, and put it on my diamondback. now when i try running it, it will Pop loudly every once in a while, it will only stay on for about a second at a time, and i feel bursts of air coming from by the engine. i tried running it without the pipe to see if it was backfiring, but it still did the same thing.
