New member to the site. Does anyone know much about the removal of the "goats belly " from a vn750. Is it a good idea to remove it or not?

Welcome to the forum. You may find an answer to your question in the Vulcan Verses toward the bottom of the page. Can also do a search. Are you wanting to change the way it sounds, or remove a heat source for the R/R? R/R is easily relocated, and just removing the GB doesn't seem to improve the sound of the exhaust according to some folks here who have done it.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Welcome to the group.

Know much about the Goats Belly? Seems to me I've heard that term tossed around here once or twice....

Welcome to the vulcan madness zip5. Opinions vary as to the pros and cons of removing the belly of the goat, or power chamber, as Ma Kawi calls it. It may decrease your low end torque a bit if you remove it, but is supposed to increase top end horsepower. I guess it depends what you want. I`m a big guy, 5'11" and #300. The stock vn750 has plenty of power and speed to keep me happy now. That may change as I get more riding experience though.

If most of your riding is local, you may prefer to keep your low end acceleration for around town. If you are looking for louder exhaust, you will probably be best off with some aftermarket pipes like Vance and Hines Cruisers or similar. If you go this route, the GB has to come off, I believe.

Just changing your exhaust doesn`t seem to increase power or fuel consumption much, unless you do an "ear shave" to the air intake boxes and replace them with "pod filters" that attach directly to the carbs. You need to rejet the carbs after a shave, and you pay for the incresed power with higher fuel consumption.

Sorry for the long answer to a short question. My advice is to ride the bike for awhile, until you decide what are the most important aspects of riding are to you. Personally, I am leaving the GB alone for now, and experimenting with drilling out a spare set of mufflers, in an attempt to get a little more rumble and deeper exhaust tone.

If you take it off, keep everything, in case you want to restore it back to stock, if you don`t like the new and louder sound. JMO

If your looking for more sound from the exhaust removing the GB will indeed give you more rumble and tone.You may also want to drill out the baffles if you are wanting more sound out of your bike. Removing the GB will get rid of about 15 to 20 lbs of bike,and it will run cooler.As for a slight power loss I have not noticed it at all. I think in the verses it said something like one 10th of a sec over ten runs 0-60.So nonthing to worry about. And welcome to the group
