V-Star 1100 Jets/carbs/intake

So there is a lot of info out there on the web but I'm missing some info about the actual parts I'm looking for. So, Ive removed the stock pipes, installed the Cobra Slash-Down Hot Rod Speedster Exhaust pipes. So this winter I also bought and intend to install a new air intake, Baron Big Air Kit...so naturally its time to re-jet the carbs...lets go! But wait there's a problem I need help with...So with the exhaust I need to re-jet, with the air intake installation I need to re jet...What jets do I actually install? So each modification calls for a different jet install, and they're quite different.

Baron kit recommended for the B.A.K. comes with:
- 4 main jets 107.5,110, 112.5, 115
- 2 pilot jets 22.5
- 2 needles and clips and cap screws

Cobra suggests this kit:
- 6 main jets 2 each: 165, 170, 175
- no pilot jets
- 2 washers & needles
- some e clips and drill bit and screw

Very different understandably. I know I don't want to buy the kits, so do I do this: replace Main jets individually, "165, 170, 175" as stated from Cobra (which size to try for front and which for rear?). Then replace pilot jets 22.5. And do the needles to to be replaced, adjusted or left alone? Need washers or?

Is this a good plan, or is there a better way to attack this. I'm pretty good with my mechanic skillz and tools, this modification doesn't intimidate me except for the lack of knowing which parts are needed to get this right. I have watched a few videos and read a lot of posts, called a few shops but haven't found what I am looking for. I have removed the Mikuni carbs from the bike, got 'em on my bench. Haven't started opening 'em up cuz was wanting parts to complete this first.

I don't know why anyone would go to all the trouble to do what you are doing. Do you not like the V-Star 1100? Why does it need to be "improved"? Why not just buy a bigger bike? Is a modified 1100 cc V-Star better than a 1300 cc V-Star? If your bike had a 2000 cc engine.....would you try to improve it? I just don't understand the reasoning behind all this. Lots of people buy cars and trucks but very few do any modifications to "improve" their performance unless it's for racing. I could see someone replacing broken parts with parts that would improve performance but not improving something that already works great. OK...from one comment, trying to ride at 70 mph in 5 th gear was not possible. Any bike with 250 cc engine can do that.

plenty of people change the exhaust and intakes on their cars for normal street use. Buying a bigger bike isn't always an option. We aren't all made of money. It costs quite a bit more to buy a bigger bike than to buy an exhaust and better air intake to go with it. Reason for buying the exhaust could be because they like the sound better. Or perhaps they want a few more HP out of the bike they already have. And why not if doing so makes what you already have that much more powerful?

Well the exhaust was the first modification...it was really quiet and when I was riding with others on bikes at times I couldn't hear myself...so could cars hear me if they couldn't see me? Then of course is to re-jet with a new exhaust. If im re-jetting with a new exhaust lets do an air intake modification and get some horse power out it as well. And why else...its fun. Im getting a good sounding bike, higher horse power, learning, and having fun. And to answer your question if I had a 2000cc bike would I do this? Of course!

So Looking at the chart (attached w/ thumnail below) from https://sites.google.com/site/vstar1...g/carb-jetting this is what I come up with but is still very unclear. I installed the B.A.K from Barron and they suggest 22.5 for pilot jets, but the chart says no change or 17.5-20.0, not sure how to read that for intake. So I assume POD is referring to exhaust...what is POD? So my Cobra Slash-Down Hot Rod Speedster Exhaust pipes are 2 to 2 not slip ons...so for main jets 150. Am I reading this right? Also do both carburators get the same main jet size, unlike stock? Anyone know?

The hardest part of this is figuring what parts. So my Cobra exhaust came with referral of an jet kit that I was wrong about and is no longer available so I'm not sure what jets they recommend. Ive the carbs on my bench apart and hoping to find jets tomorrow.
150 main jets 22.5 pilot jets add a washer/spacer/shim ...I think that is whats left my parts list to get. I understand this is trial and error of sorts, so here goes...hoping to find these jets tomorrow, and get the bike up. Between two jobs its hard to find time, but the road is calling with this nice weather.

Pod kits eliminate the intake box placing individual air filter (pod) onto each carb.




Your BAK still uses the stock air box with the air restrictions if it's this one.



You are only adding better breathing before the air box with the BAK. If it was me I would follow know working jetting recommendations that are recommended.
