Triple Mikuni carb, use center carb on the side

[misiek303]

Unfortunately, I screwed up my right carb. I have one center spare that I potentially could use. The only difference is that the center carb has fuel delivery on both sides that are connected to the left and right carb. I would need to plug the one side fuel delivery chamber.

Pic attached. ( on the picture its another broken spare, as you can see has broken leg for the float level, if I could fix that, that would be ideally ). But I am pointing to the chamber that needs to be blocked some how.

What would be the best way ?

Yep, been there dealing with extra throttle shaft holes. Original JB Weld is impervious to ethanol and will adhere. JB Quick is not, give it a pass.

Maybe @Jim will chime in. He had a nice fix for one of those.

If you don’t have any access to a mill or lathe, I could see the transplant possible with an inserted post.

Cut one off a bad carb and put it on your good carb.

Yeah, I made brass pivot post replacements and pressed 'em in. You'll need a lathe to do it though

As far as plugging the inlet hole, I like the J B Weld option.... yeah, the original formula.
For best adhesion use a gun bore brush or similar to clean the hole first. You want to remove as much of the oxide layer as possible.

Not the prettiest but I call it success. I will use this carb and swap it instead of the one with broken mixture screw in the hole.
The hole is clogged for good in the other carb. I tried to drill it, but instead of in the center I drill it next to the hole.

Rough around the edges... but I'd call that a win!!

As long as it’s straight and doesn’t make the float needle bind it should fly

I assembled all. Bikes runs again. Very reach, need to work on that. Case closed.
