Has anyone put the 44 mm SE carb on their bike. If so, how do you like it. Will be going on a 2006 w/ 1200 conversion. V&H straightshots and upgraded ignition.

 

You don't need that big of a carb unless you have a real fire breather. The stock 40mm will easily make over a 100HP.

 

you dont need a huge throated carb unless you are running at 7k RPM ALL the time.

the smaller throats make more torque at low rpms and will support good engine breathing up to redline.

stick with the stocker and upgrade the heck out of it!

 

Appreciate responses, but has anyone actually put the bigger carb on. I have already done alot work to stock carb.

 

Too much carb as everyone says but sounds like you want to anyways! Big carb does not = big HP. You will also need a SE-type sized manifold to fit a 44mm carb and grey-colored carb seal gasket to mount it (stock is a 40mm with a black gasket). The 44mm on your bike (as listed for mods) will have waaaay slower throttle response, poor or erratic idle and lurching at slower speeds, poor gas mileage, and fouled plugs because all you're doing is dumping gas in it's throat esp. if you're not running a free-breathing AC and a cam to support it.

 

What have you done to it already?

Custom Float?
Performance Slide Needle?
Vortex Emulsion Tube?
Light Weight Slide Spring?
Drilled the barrell?
Jetting?
Ported and polished intake?

Unless you mod the motor. A bigger carb will make the bike run like chit and have less power than before.

 

I have it on my 2002 883r/1200. It is part of a build that included thunderstorm heads, buell high compression pistons, SE coil, SE ignition, SE cam kit, SE Pro 2-! exhaust, and a forcewinder intake. the best HP I can get is 74 hp. my tech says it's because he can jet the carb properly, it spits and backfires like an SOB and runs rough. He recomends I get rid of the 44 and the forcewinder and my bike should produce much higher HP.

 

Talked to local dealer who did my 1200 conversion and Indy in the area. Both suggested the 42mm Mikuni flatside for the Sportster. Anyone with any actual on the bike experience. I know the Mikuni will be a little more difficult to tune initially.
Thanks.

 

Sorry Dude but a bigger carb isn't going to help that combo, you are making almost exactly what you should be making for HP.
Your tech is a retard if he things a bigger carb is going to help.
You are basiclly running a stock Buell which isn't much compared to the aftermarket, for some reason you think you should be getting more HP than what a stock Buell got, if you want more HP then you need to spend a lot more $$$$ on head porting and really big cams.
My bike was built by Head Quarters and it puts 85 HP to the ground using the stock cams.

 

I wouldn't do it as stated several times above....you shouldn't need a new carb until you bump up to a full-on stage 3 (or a bigger engine kit). It's a waste of time and money if you don't have the ENGINE to go along with it. Even the Mikuni is a waste, you won't notice much difference at all with basic mods.

If your carb is well-tuned, then it's not the problem. Next step you might want to take would probably be ignition, heads, cams, etc.

If you put that carb on your bike, I guarantee 100% it will NEVER run right, or (if you can ever manage to get it out of the garage) you will have MAJOR top end issues in a short amount of time.

A well-tuned CV will go a looooooong way. Spend your money on parts that might actually make a difference - that's my two cents.
