82 750 airbox modification

[mret430]

Okay, well since I bought the bike 7 months ago the other owner decided to take out the air filter/box under the seat. He ran a slinky type/ air duct hose from the back of the carb airbox, down behind the right side cover. the end of the hose has a styrofoam wrap around it. Really no problems with the bike running but tell me your thoughts and should I get it back to stock.

Thanks

Suprised it starts and runs well. These bikes are usually particular about having the exact right amount of restriction in the air intake.

+1.

I'd take a good look at your plugs and make sure you're not running to lean.

Are you sure the PO didn't re-jet the carbs ?
