…And this important caveat from the author, “…the earlier bikes have 38mm carbs where as mine is 34mm so keep that in mind. If your using it on other models there are probably other bellows at the auto parts store that would work if this one won’t fit for you. Just go during a slow time and have the counter guys help you rummage through the shelves. Most of them are pretty good sports.”<\/em><\/p>\n

I needed replacement intake air ducts, because I had one good intake duct and one off of something else.\u00a0 As I’m sure the rest of you 750 people know, the ducts are very hard to come by.\u00a0 Frankly, I wasn’t all that pleased with the design anyway, so I stopped hunting for one and came up with my own.<\/p>\n

Here’s what I used:\u00a0 Rack and pinion bellows for a Prizm.\u00a0 You can buy them right online from O’Reilly….<\/p>\n

Bought two new ones and cut them to fit.\u00a0 Works great.\u00a0 Has some give, so it will handle the vibration.\u00a0 Much easier to connect to the carbs, and seals better than the originals I think, too.\u00a0 I haven’t put the carb clamps on yet because I don’t have any.\u00a0 I’m working on that next but it’s such a nice snug fit I almost don’t think it’s necessary.\u00a0 It’s automotive grade rubber so it should be okay with the heat.<\/p>\n

Did all the work on it while the air box was still in the frame too which was no small feat I might add.\u00a0 Still retained all the original components (except the ducts).<\/p>\n

Here’s a shot of the business end.<\/p>\n

Here’s a shot showing the bellows are actually sandwiched in between the clamps.\u00a0 The seal is impervious to water.\u00a0 All the air must pass through the air box opening and the filter.<\/p>\n

Note from Biquetoast:\u00a0 Please note that I have not done this\/these mod(s) myself, so I cannot validate any of the claims here, nor do I know the models for which this will work.\u00a0 Although if you’re a 750 twin rider like me and AtLarge, you will likely face the need to find replacements like this someday too.\u00a0 So if you ever try this, <\/em>please let me know <\/em>and I will update this page if I ever do this as well.\u00a0 Good luck!!
