Main jet thread too large.

Strange. My number is 49400. The plot thickens.

A search turned up that 49400 belongs to an '82/'83 8 valve GS1100 G/GL/GK.

Third or fourth post in this thread lists the jet sizing.

Wow thanks, that's incredibly useful. Is there any ballpark jet size that's understood to work well for pod filters and aftermarket exhaust or is rejetting just a bunch of trial and error?

If your carbs are, indeed, 49400s, they are 34mm carbs, which are too big for the bike.

It's interesting enough that the same 32mm carbs are used on engines from 550 to 850 (with jetting changes, of course), but it will be hard to get the 34s set up for your small engine.

I am also curious how somebody found boots that adapt the carbs to the head.

Well I specifically ordered new bs34 boots (previous owner thought high temp rtv was an acceptable sealer for cracked boots) and they fit right on the head. The question now is if the carbs will fit the boots. I'll go test fit that before anything else.
