Replacement Carb Intake Manifold Boots for BS34

[Gowron650]

I am trying to find replacement carb boots for my '83 XS650 Heritage Special. I have bought two sets of replacements on ebay, but neither will fit properly.

The OEM carb boots have a lip that is about 4mm from the edge, which matches the lip around the outlet of the BS34 carb. The two aftermarket pairs I have purchased so far have a lip that is ~8mm from the inside edge, which doesn't fit. Even using a little grease and a heat gun and forcing them on there, they just pop right back off.

I have attached a picture for reference.

Does anyone know a reliable supplier of replacement boots that is still in operation? MikesXS is sold out of these unfortunately.

Where'd you get them from? I just got a set from CruzinImage in Japan but haven't teet for them yet. I'll try tomorrow and let you know.

What you want to look for are boots made by ARS. They were the original supplier to Yamaha. The boot will have the ARS label on it .....

I think the ones sold by Tourmaster are the ARS ones.

Yes, Tourmax

K&L used to carry ARS boots also. Not sure if they still do though.

Yes, another shout for Tourmax branded BS34 rubbers. Bought some a few weeks ago and I was pleasantly surprised to note the ARS logo on them.

I bought mine from Cruizinimage and although tight, seem to work great. Cruizinimage is fast and good.

Did you find a set that works well? I'm at the same point in my project and the set I bought from Mikes XS have the same problem You mentioned. The molded rib is not in the right spot and they don't sit flush/flat when I force them onto the carb. I figured Mikes XS was the place to get them and I wasted $50.

Tourmax inlet rubbers, marked ARS as per the original fitment. Work fine and not difficult to find.

Yes following the advice on this thread I found a pair marked “ARS.”

You might be able to find something cheaper but this is what I bought:

I’m also in need of new manifolds, I found these tourmax ones on eBay I just purchased.

So I found out those tourmax boots I mentioned are for BS38 carbs, 46mm opening.

Good thing I asked before he shipped because I have BS34 carbs, 40mm opening.

Send them back. My new GoTo strategy for crappy parts…

Crap! I think that is the same seller I bought from. They have already shipped.

Looking for new intake boots for a '81 XS650H. Not having luck finding Tourmax boots. Looks like JBM has angled BS34 boots. yamahaxs650 also advertising boots with proper groove depth. Anyone have experience with the ones from yamahaXS650.com?

Thanks Mikey,
JBM's - designed to use without gasket or metal cover, even with UNI pod airfilters (no airbox support for the carbs and filters - just cantilevered)?

 

[Mikey]

The 73 I had and the 75 I still own are stock setups with airbox so I can't say for sure
I just know they aren't the cheapest but they are very good
How heavy can the Uni filters be
