I can check cam timing again using the method you describe. The bike runs so well that I don't really suspect that it is off. I saw a video of how an xs650 will run with a tooth off and it looks like it would be pretty obvious. With the crank at TDC the pin on my camshaft is at 12:00. My...

At second glance, the advance replacement cap would be putting my advance rod slightly ahead of the cam. That would advance timing and in theory would require the plate to be adjusted more towards the retarded position? I've verified the cam timing is correct.. I was almost worried I really was...

I was at the 100 mile mark on the engine so I went ahead and did a head re torque, checked cam chain, and reset valve lash. I also adjusted floats back where they were supposed to be (both set high), adjusted mix screw back to 3/4 turns, and sync'd. I was still experiencing the intermittent...

Thanks guys, I appreciate all the help. A couple things I should mention: When monkeying with carbs a couple weeks ago, I adjusted the float in the right carb to try and lean it out, didn't help, but I never changed it back... The stalling issue will occur even when bike is stationary on...

I cleaned out the bowls, reinstalled the pilot jets, put a light coat of oil on the gaskets and reassembled the way they came off (problem bowl on left) I just snugged the screws as I did every other time, trying not to over tighten. I ran the bike and it behaved a lot differently. High idle...

I did some block sanding on the bowl I was having issues with and pretty much worked out any irregularities. I also sanded a bit on the other bowl even tough it didn't seem to be giving me any problems. It turns out the "good" bowl had worse pitting/gouging than the other. Good bowl is the last...

Ok, so maybe not such a crazy idea! I would like to figure out whats going on with the bowl, but if I can get it to run nice with a modded pilot I guess I can live with it.

I compared and inspected both sets of pilot jets. same pattern and same hole count... I also took a closer look at the bowls and was thinking maybe the pilot was sitting so far down in its seat that it could be partially blocking the bleed air passage, but I shined a light through and could...

Interesting... I will check this out. I did compare the 45's to the 42.5's last weekend and noticed a slight size difference in the air bleed holes and the fuel holes at the tip. The 45's were both larger, which is what I would expect I suppose. I didn't take note of the hole count. While in...

Ok, I wasn't sure if that could effect the Idle circuit.. Choke definitely works and carb clean spays through passage just fine. edit: I realize it would and does effect the idle circuit, but yes I meant isolated to the bowl. If that makes sense...

2M, I swapped the pilot jets in the first run of testing after I swapped carbs and bowls. The corrosion you see is actually something on the surface and not pitting. It appeared mysteriously after the initial carb rebuild. It doesn't wanna come off with solvent/rag. Oxidation maybe?? I will...

I hadn't noticed that there was another jet that is permanently pressed into the bowl. This is for the starter or enricher circuit? would this have any effect on how the bike runs at idle even if enricher was not engaged?

Grizld1, That would be awesome. I very much appreciate the offer! I will keep that in mind if I cannot resolve this issue.

Here's a few side by side photos, sorry they're not the best... (problem bowl on left) They appear to be the same. I forgot to mention that I bought a set of "donor" carbs basically just for a float bowl. One of the carbs that came with the bike had a cracked bowl. I found the donor set on...

Tried grease on gasket, didn't change anything. I also used some valve lapping compound and ran that drill bit in reverse and it looked like it made the pilot seat pretty uniform... Gary, the carbs are supposedly 1970. I will snap some pics today after work. I didn't do anything too invasive...
