Huge power loss after cleaning

Hello all,

I had a buddy work on my bike. I have a 2001 750 Vulcan. He said the jets were clogged and I have leaks in both exhaust pipes at the gaskets. He cleaned the jets, tightened the exhaust pipes (still need gaskets will get them soon). After doing all that the power loss from when I first brought it to him is huge. On a moderate up hill i can hardly hit 55 mph. He checked the carb and everything seems to be in order (fuel, cable, vacuum synchronized the carbs, serviced the air cleaner, idles great, starts fine), so now we are at a loss. We both start school and are taking a break from the bike for now but we are fresh out of ideas. Thank you for any and all help.

P.S. I believe my bike is degoated because there is no converter and both pipes are on the same side.

Sounds like he routed a vacuum line wrong. Check the vent line going into the back of the right airbox that it's not bottomed out. (cut the end at an angle to prevent this)

I looked and plugged it in. Now I have a top end power issue. From 4k on it is gutless. Can that be caused by lack of back pressure (due to blown manifold gaskets)?

Thank you for your help
