Do you have a shop close to you that can show you were the idle mixture screws are for sure,and than you can do the adjustments for yourself?

Maybe it's just my uneasiness of buying a bike that idles funny and a seller telling you it's something simple, but I smell a rat.

Just based on your description, it does sound like a bike that just needs an idle adjustment or larger main jet, given that he put new exhaust on there. However, if the previous owner was knowledgeable enough to swap out the exhaust, why didn't he go ahead and finish the job? Idle adjustments and jets are as easy as he lead on... so why didn't he do it?

Like I said, maybe it's just me being paranoid but I would be asking that question if it was my bike.

-Anyway, to deal with the issue: Your bike has twin carbs to feed the V-twin engine. Twin carbs are just as easy to work on as single, except you have to make sure that they are both operating properly if you want the engine to run right. The other issue is removal. Not rocket science. But it is more complicated, espeically for a rookie like yourself, because there are more parts involved and they rest at funny angles.

Unless you can find a detailed walkthough on a Honda Shadow forum somewhere, showing you how to remove and clean these things, then I would call your local Honda dealer. Ask them to install a low stage jet kit (about $80) and have the peace of mind that your bike will be ready to roll for a long time. If the Honda dealership wants to charge you something crazy for the work, just find a generic bike shop (probably not a chain store) and have them do it.

A buddy of mine has a Vulcan 750 that looks very similar to your bike. (In fact, just from the photo, I thought that's what you had.) He's had idling problems since he bought it and it's not because of intake or exhaust. We spent two weekends making that thing look like a brand new bike including removing and cleaning every piece of it you can imagine. He still had idle issues and turned out it was just a by product of an old worn-out carb. So, it's probably time to go head and have the carb rebuilt. I mean, the bike is an '86. (Don't let the word "rebuilt" scare you. All they do is put new seals in it, a couple of o-rings and all new jets.)

Hope this helps.
Good luck with your new ride.
If you want to try the poor-man's method, just pour some carb cleaner in the tank and ride until it you have to fill up again and see if that does anything to help

mess with any part of the intake or exhaust and you have to jet carb to make it run right, thats just common sence right? anyway good luck miss

There are a few exhaust systems that were designed with the sole purpose of making noise without increasing flow. (Think Cobra F1 & others) In those cases, you don't have to change anything at all. Just slap them on and ride. It also depends on the nature of the particular bike. But speaking generally, you are correct.
