43mm KEIHIN CARB BUILD
i aquired these from axgrider73,after inspecting them they turn out to be very cool carbs,but will have to be total setup again.converted from a 2 pump setup back to a 3 pump setup,spaced and throttles clocked.they will find there way onto the pro and hopefully the existing ported intake will accept the 43's in place of the 42's which will eventually be converted to a 2 pump setup and installed on the virage probably this fall with a ported intake and stiffer reeds,so what color should the 43's be painted or should i once again turn them into a lonestar set matching the 42's???

Paint them all the same color. I think it would look much better.... Kandy Red from House of Kolors would be a real fine choice!!!

houston we have a major problem
the center carb has a major issue,the brass tee fitting was not pressed in but was threaded in,and the opening was opened so large that the body casting has failed,this was a fire waiting to happen,can anybody weld aluminum cast to fill this void back in and then re drill a passage.it won't have to hold a fitting only be air tight weld.any takers to help resurrect a killer set of keihin carbs????

Here are the pics TX. PM me if you would like me to email them to you.
I can't wait to see what you are able to do with these.

in the upper right pic you can see where a brass tee was added.the carb body was drilled and tapped to the point the casting has split open down the left side.open to suggestion on how to repair???anybody think they can weld the hole full and then redrill a passage thru??doesn't need to hold a fitting only pass fuel thru without leaking otherwise it'll go on the scrap heap and it'll be a twin set.already got 2.0 seats for them but can't go any farther unless i know how to set them up for someone else....twin pumps,run the cast in restrictions,convert to external return restriction.somebody did a killer job making these would be a shame to not use them

Could you fill it with a lead slug? There are also some sticks that are sold that are suppose to be for low temp repair using a propane torch on pot metal and cast alumium.. I bought some at a auto show at one time, But have now idea were they would be at in Michigan if I still have them.

either have to press a tube into the casting past the damage,jb weld around it,and flat finish all of it.or weld into the hole something that will penetrate into the material and create a leak proof bond that can be flat finished,if it leaks thats gonna be an explosion waiting to happen

A good machinest should have no problem making an insert for that. I'll bet Bruce at Wet Wolf could fix her right up.
I second the Kandy Red as well.
