Swapped from S&S to SU

I agree with G,that thing looks good and fast juz sittin there.
I gots SU carbs,got two HIF {internal float} like Yours and got HS4s with the side body float tanks on em,not fer sale though,they be for Mee MG.erbox:)

I did have a S&S G single carb mounted to the MG and now I have the HS 4s on thare and between the two carbs I do`nt think there is much difference in performance.
UHHHHhh,if You wants to sell Yur E send Me a PM.

They are super easy to work on. There are basically three needles that work well with a shovel, compared to hundreds for cars. A needle can be changed in about 5 minutes.

The power increase is mind boggling to say the least. Plus, they look very cool. There are only two drawbacks to them. Some feel the stick out to far. Also, sometimes, if you have one with a worn out slide the piston will be a bit loose in the bore and if it comes down to far, it can contact the base and shut off fuel flow at idle causing the engine to shut down. What a lot people do in that situation is put a small piece of rubber in the slots below the piston crown to keep it from bottoming out. With that little mod, it works perfect.

When these are mounted on cars, they require some oil in the dashpot. Now you see why the joke goes...the English are the only people who could make a carburetor that leaks oil.

When they are mounted on a bike, only some WD-40 is used to lube the slide, no oil is needed.

I use 20-50 motoroil in the slides on Mine,for a vehicle application,without oil,the slides would open too quick and cause a loss of power and popping/backfire out the carb which is the same results from using too light of oil.

I have been going by the Rivera instructions. They recommend only using WD-40. But everyone's bike is a little different, so as always go with what works best.
