One carb for V Star 1100 instead of two   Technical-Bikes

Hi, how did you lift your fuel tank?

It lifts the front only, basically the tank cup section sits on top of the frame stub, that's enough clearance.

I made a bracket that fits over the frame stub that holds the tank rubber mount and into the C shaped cup on the tank where the rubber mount sits.

If you have a fairly flat air filter I would use an extension to move the carb out, which is what I will do in the end.

Btw, this is on a custom, the classic might have different clearances?

When you make the intake longer with the extension it will probably change the characteristic of fuel flow, overwise companies  would do the intake for our model espesialy longer?

By the way, what air filter did you mount to your cv carb, do you use stock mufflers and did you buy you carb with suitable jets  or you tuned it yourself?

Longer intake runners = TQ. The V* motor is not designed for TQ. Basic engine design 101.

Intake is about the same length for the front cylinder, a bit more for the rear. Needs maybe an inch extra to clear the tank, would that make a difference who knows. 

Carb came jetted, didn't have to touch a thing except adjust the PMS a bit.

Air filter is a universal flat one from eBay, had it on my Harley before the Yamaha. The back plate is blank, so you can drill the holes to suit the carb.

Stock headers, 2 into 1 exhaust muffler, again eBay.

Everyone has an opinion and as I said I did the change for cosmetic reasons, the unexpected benefit was the big improvement in throttle response and rideability.

Maybe mine was super sluggish before, it didn't seem to be and I have a GSX1400, so I know massive torque and acceleration!

Hi, thousand thanks for your clarification, I decided to buy such kit on eBay like yours, hope the installation and tune would be successful.

No worries, make sure you get a carb suitable for the TPS, not all have the mounting holes in which case you need a bracket.

Also the TPS turns backwards when on a on a Harley style carb, it's a simple wire swap if you are ok with soldering.

Just to clarify my statement regarding performance with a single carb. It wasn't an "opinion"......it was made after seeing quite a few different dyno sheets over a number of years with different intake set ups. "It feels faster" doesn't really mean much until the numbers are on paper.

I"m sure it is an increase over a stock set up, which is horrible. I'm glad your results were favorable.

No problem with having an opinion, everyone has one, I used that wording to highlight that single carb is my opinion and not other people's, not to have a dig at anyone, life is too short.

Average results with KJS and HS40 carb is 60 hp and 84 tq for stock bike. Will hold it own to 60 mph against any Vstar with cam, pods and exhaust. Extended to 80+ with proper setup Super E carb. 

Not everyone is into top speed and can be happy with $600 intake and single carb. Especially advantageous if you pull a trailer or love curvy twisty roads where speed is irrelevant.

1 have a stock 2005 bike with cam, pods and exaust that loves screaming down the highway, but a 2006 with KJS and SUPER E for backroads and mountains. Each has it good and bad.
