Default New Tire now decel pop

I got a new rear tire and the shop had to take my top pipe loose and rotate it up to get my axle bolt out. Now I have a decel pop just before it gets back to an idle rpm. They didn't touch my carbs I don't know why it just started. It has been jetted for the drag pipes and never popped since I had it.

You have an exhaust leak either at the exhaust port or the tailpipe/muffler connections more then likely.

I can't hear an exhaust leak, but the only place it could be is on the exhaust port because they are just straight open drag pipes no mufflers. I wondered when they loosened my pipe and rotated it I was wondering if it would cause an exhaust leak. I can't hear it but I am sure they caused it.

Yes, they could have damaged the crush washer, causing a leak. With a loud exhaust you're not likely to hear a leak.

I'm with JPR. Whenever I take off pipes, I replace the crush gaskets.

I'd ask the shop to replace the gasket on the pipe they took off...no labor charge since they should have replaced it when they had it off the first time.

I called them they told me to bring it back by. I may have to go to the Honda dealer to get the gasket. I had the tire replaced at the Yamaha dealer because they had the best price on the tire and had it in stock and they included mounting and balancing as part of the tire price.

I went back to the shop today. They left a nut off the exhaust port and pipe was hanging by 1 nut. The other one was down by the starter so they put it back on. They found crack in my bottom pipe's heat shield. I told them they weren't like that last month when I cleaned it up. Anyhow there is still an exhaust leak on the bottom pipe inside the heat shield. It is slightly noticeable. I guess I am going to take the pipes off and see if I can get the pipes out of the heat shields and see if I can get the bad spot fixed. I would still like to find another set of pipes. I am thinking I would like to get some stock pipes if someone is pulling theirs off to go aftermarket.

Wow, another reason I do all my own work. Shops screw things up all the time.

Ha! Yamaha! They tortured the poor thing while you were gone!
Those pipe are really expensive. Look for aftermarkets for comparison.
