Got my first pipe couple Q's....

So I have a few puch powered bikes with 14mm stock carbs and intakes. One cast iron head, one aluminum. Got a techno boss as my first pipe. The iron loves it, the aluminum hates it. So iron man/high torque she went. Rides nice. Very little low end loss. Four strokes just a bit under 1/4 throttle and pins the 30mph needle wound up after a few seconds. Doesn't 4 stroke at all topped out. Just a wee bit if I don't give enough throttle on take off, low speeds etc. Jetted mid sixties. Pretty much stock 2hp hi torque. Stock air filter with the little open non-dampered pipe. When I let off the gas it pops a bit from the exhaust but not jerking the bike or anything. Is this all good/to be expected? Does the setup sound about right? Gonna blow up my shitz in a hundred miles? Plug looks brown. No white ash. Sorry so long. Just wanted to give as much info as possible. Thanks all!

That poppy sound is normal for that pipe, you should be kool.

Sounds like you're all set up and ready to blast.

And yeah, the popping is just un-burned fuel that burns in your exhaust. Gotta love that typical 2-stroke pop :P
