So I have my kat running 'well' (as far as I would have known) and finally felt comfortable with taking her for a test run. She was seeming perfectly fine at a stand still.
When dropped into gear the RPMs dive low and the early throttle is initially hesitant. After just a few (less than 4) laps through a deserted parking lot, the RPMs refused to come down as the throttle was let off. Was using 40 pilots, 102.5 mains, and 150 air jets, 2.5 turns out.
Butterflies are reasonably bench synced (by violin string). I went on an airleak hunt and wrapped the airbox boots in weatherstripping, sprayed everything down with ether and found nothing. Nowhere could I get a rise in RPMs, I tried the join between filter "crate thingy" and airbox, the airbox boots, the drain tees.
So then I tried 42.5 pilots, 110 mains, and 140 air jets at 1.5 turns on the air needle ... it entered the 'hanging idle' and died shortly after not in an overrev, but in a "it just dipped out" as I let the clutch out. It seemed to want to go higher on the RPMs than previous try. Once I started it up again. Adjusting the idle screw results in either a racing idle or imminent death. There was some dark smoke out of the exhaust once I fired her back up and rode her home.
Plugs are black. Except cylinder one, who looks kind of between lean and healthy.
Checked the valves, the intake on cylinder 4 I'd like to have changed out but couldn't for the life of me spin the bucket to get at the tab. Anyone have any advice on spinning those?
Pulling the clutch results in the RPMs rising, up until a point where it drowns.
I'm definitely going to go ahead and replace my #1 and #2 airbox boots, along with the intake boots at the end of the month.
This is the first time the bike has actually been ridden since last year, so may this clear itself out? And one of the first few times it's been ran since changing the intake o-rings, so could this go away on it's own once it's been spun around for a while or should I be fiddling the air screws and float heights?
