Post-TB Tubes - Ducati.ms

So I removed the Evap. Canister on my Hyper a while back, and had plugged the nipple locations with screws. Upon further investigation I realized that the nipples she be left and should be used to bridge the two TBs.

However, I managed to break off one of the nipples in the post-TB tube yesterday when I was trying to plumb it back up.

Has anyone looked into if there are aftermarket post-TB tubes available, or if there is a "big-bore TB" kit available for the hyper? I don't know how much success I'll have trying to remove the broken portion of thread, and figured I'd ask if anyone had looked at alternatives before looking into a replacement tube.

Bridgeing the two tubes into one tube is not a good idea. What that does is equalize the vacuum between both cylinders at idle. Idle vacuum is correctly set by adjustment not an equalizer tube...or else Ducati would have provided one when they built it. Plugging the nipples is the correct way. And not with a screw. Use a small bolt and screw it into the rubbber...or buy nipple plugs.
