I guess it's an improvement from how it WAS running the other day....
[backstory]
I pulled the carbs, and did a ground-up rebuild on them, because I was not satisfied with their performance when I got the bike. It's an 80 850L, and I got 4x carb rebuild sets of Ebay for a good price. Installed the rebuild kits, along with a Dynajet Stage III kit, using 165 main jets, and clipped the needles on #3 from the top, as per instructions. Synced the carbs by wire method, and got them running BETTER, but not perfect.
Specs:
1980 850L
- Stage III Dynajet kit
- K&N filter pods (SU-9084)
- V&H 4-to-1 exhaust (with baffle still installed)
Upon cold start, I'd have to choke the bike all the way for the first few minutes, then choke halfway for a few more. If I gave it gas, she'd start to stumble and want to die out. I had the option of running a 180 or a 190 air jet, and chose the 190.
Now, the throttle wants to hang for a few seconds when I let go, yet I properly drilled out the slides with the included drill bit. Am I still running too lean? If I am, should I shim or re-clip my needle so that it sits higher on the slide? The problem diminishes when she warms up, but does not go away entirely. I can wrap my pods with a t-shirt and it runs alot better, so I am assuming I am allowing too much air vs. fuel? I am also getting an occasional backfire here-n-there on when I let go of the throttle.
Hope that helps.
