All, I've been lurking for a while and got some great help as I started on my bike lsat year, so I need to start with a big THANKS for all of the great info on this site. The bike is running "OK" and I'm riding to work 2-3 times a week. I've slowing, but surely, been tuning everything in, but...

Can someone confirm that the small hole inside the float bowl (center of the photo, not the drain plug) and it's mating location under the gasket surface is supposed to be plugged on a late 1970's BS34 carb? I've thoroughly cleaned the passages, but it looks like there's brass plug inside to...

All, The bike is running great and I'm tweaking a few of the more aesthetic details more to my liking. I'm not sure I have a "style" in mind. Just something a bit custom to cruise around town on. Anyway, I picked up a "bobber" style tail light and I'm soliciting some design input on the...

All, Does anyone have any tips on removing the small screws holding the brass butterfly in place? A screwdriver won't budge them and I'm afraid of stripping the head with too much force. I have a small easy-out, but I only want to use that as a last resort. Plan C would be to boil the...

I'm looking for a carb body for an 80-82 carb (fuel mix needle on top of carb). Mine has a broken float post and a wedged main jet (the PO didn't use a washer). I'm also looking for a corresponding brass float, but not necessary. I don't need any jets, just the aluminum body. If you have one...

As I was disassembling my carbs for cleaning I pulled out the fuel mix screws without realizing there was an o-ring and washer in addition to the spring. I have them, but I didn't see in what order they were assembled. Can someone help me? The old schematics are too blurry to tell and a a...

Hey everyone. First time poster, long time lurker. Anyway, recently picked up an '78 XS400-2e (kick only) that's really clean. It needs carb work and timing adjusted so I haven't got it to run yet. Can someone confirm all three ignition key positions? My guess is (from left to right): off...
