I'm sure this has been asked before, but if I used the Mikuni carb mount 990-842-007, will the Mikuni TM34 carb clear the crankcases on an H2?

I'm quite sure a TM34 will insert into a good stock inlet manifold on an H2. Same spigot diameter as a VM34..You could poke it in and see if it hits.

No, the stock H2 inlet manifold is only 37 mm, the TM 34 is 40 mm, it might stretch that far but not the old ones I have.... and I don't have any TM34 yet, the reason for the question was so I didn't buy them only to find out they don't fit...

You can use the stock ones, if they are fresh and still "supple", as they do need stretching to fit. I have seen a bunch of 34 flats on 750 motors so I don't see a problem. I do know some minor clearancing may be necessary.

Ive tried it both ways and the stock manifolds work better. You will have to grind the sprocket cover a little bit to clear the large drain plug on the left carb.

My carb mounts are the originals, not in bad shape and won't leak I think, but there is some slight cracking so in no way will they be supple or stretch any. I figured that if I had to buy new stock carb mounts then I was a bit closer money wise to just buying the new Mikuni mounts and TM34 carbs to fit. So it sounds like they do fit, within reason. Plus I have done some port work and am using chambers so 34 carbs seemed like a good addition. The bike in my signature has new TM38 s on it, and I love those things, their off idle response and tuneability is really nice. Thanks guys.

TM 32. And 34 are same size spigot. Buy some new Kawasaki manifolds if yours are cracked. They are cheap, a lot less than the pistons you will burn up when the manifolds leak. :)
