question regarding cobra pipes and carb jet size

Bear with this newbie but i need a question answered as i am a little confused. I purchased a VN 750 1994 that had cobra pipes on it but the carb was never re-jetted. My question is 2 fold

1. is it necessary for me to replace the jets to compensate for the different pipes and

2. which jets should be in there


thanks

With just the pipes being swapped, and nothing done to the intake (ear shave) the stock jets should be fine.

I was planning on keeping the stock air filters and not shaving them (god that sounds weird). But suppose i go ahead and go the ear shave route, is there a recommended jet size the carbs should be?

There is some information on "ear shave" in the Vulcan Verses forum off the main forum page. Lots of folks have done it, (I personally like the looks of the stock filter boxes) and if you wait a bit, Lance will probably chime in with the proper jet sizes for a shaved 750.

Give lance everything you know about the bike. Shaved, not shaved, Which exhaust & where you are geographicly (height above sea level). I think that's what he'll need.

specifics

Geographically located in Florida

non shaved (stock filters still in place)

cobra exhaust

bike came with cobra exhaust already installed but unsure if it ever ran that way. the bike also came with the stock air filters (ears) in a box seperate from the bike. I believe the previous owner was intending to do the ear shave but not sure. I have sourced out a new "surge tank" and am leaning towards using the stock air filter setup unless someone can recommend not to and use KandN filters instead.

I have a surge tank that you can have, along with the other associated goodies since mine is already shaved.
