I recommend you go to the dealer and buy them. They are cheap enough and can take the heat better than what you're going to find at the local auto parts store. I have attached the part number.

And to further what Marty has said, if you cannot get the OEM caps that last a bit longer, go for the auto parts store caps and change them once a year as routine maintenance.Mike Giroir

Once you un-can a can of worms, the only way to re-can them is with a bigger can.Comment

I just take some 1/8" ID vac hose, cut off a piece about 1" long, shove a BB in one end, put some dielectric grease on the other end and slip them on. Old Yamaha vac hose that hasn't cracked in 30+ years works perfect, new cheap vacuum hose will crack just like those caps, BTDT. Either way, 1/8" ID will fit.2H7 (79) owned since '89

The grease is probably to prevent the hose from baking/sticking onto the carb nipple and thus never being able to pull it off for a carb sync.Hi, my name is George & I'm a twisty addict!

Yep, they come off every time no problem, it sucks when they get baked on and stuck, especially the inboard ones.2H7 (79) owned since '89

Yep, I knew there was a reason to keep the vacuum fuel valves. They connect to the center two carb tubes.Originally posted by bikerphil View Post
