82 gs1100g different exhaust no pods

[Guest]

So i finally was able to get on the road last friday and get the ol girl warmed up enough to do a plug check to see if i was to lean after installing a 4 into 1 vance and hines pipe that a buddy just happen to have and gave me, sweet $300 saved. Anywho, pulled the plugs and all of them are looking perfect. A deep tan color on the electrode insulator and not to much soot on the inside side wall at least that's what I think is almost perfect. For some reason it tends to feel like I am running a little lean though, a little back fire every once and a while and a little chug every so often. Is it a good idea to go ahead and richen it up a little or should I just leave it alone?

Assuming stock air box with V&H 4-1 then:

If it were me, I'd raise the needle by removing the plastic spacer and replacing it with 3 washers. You can pick up the washers at Radio Shack. They're found in the washer assortment pack.

Make sure your fuel enrichment screws are adjusted properly.

You might want to up the mains from 115 to 120 as well.

Then do a proper set of plug chops so you know what's going on inside the engine. Just looking after a ride doesn't tell you much.

I had that problem with the backfires and bogging on my 425, and I'm pretty sure mine was running rich, so that may be a problem, anyways, I just adjusted the idle air screw and two small screws and that seemed to fix the problem, your bike may be different with the v&h exhaust, but before I did anything I would mess with the carb adjustment.
