I'm getting upset w/ poor low-throttle running
10/25/09 at 12:42:30

Pulled the plug - slightly brown, really doesn't look too lean, and performance at altitude suggested rich on the pilot. I had a thin spacer. So I put the white spacer back in - figured that would lean things just a tad. No better running.

Feels like a fuel starvation issue, but remains with the petcock on prime.

An intermittent slightly irregular hesitation. Not the lean hunting thing, just a uugghhh ugh uggh OK OK uugghhh slowing. Really doesn't feel like anything I've experienced before. Annoying as all getout.

Once I hit 1/4 throttle the beast perks right up and goes great!!! I rode the Volusia yesterday and forgot how nimble and quick the Savage is.

Dyna exhaust, 52.5 pilot with holes, 152.5 main, white spacer (but 1/3 of white spacer does the same thing). Fuel flow through the filter looks fine.

Any ideas? Any expert in the Knoxville area? I'm getting frustrated with this.

Vacuum line is new, and it does the same on prime, so that's not it. I'll pop the 52.5 w/o holes in. It's just trouble to easily get to - battery box is in the way, so I end up having to pop the battery box out to reach the screws for the float chamber.

Loosen the clamps on either end of the carb, remove the carb top, slide, needle, etc and just flip the carb (more or less) upside down. There ya go.

I'm tired of messing with it - now I've got the Volusia to go through, too. Probably get by with one tank-off pass because it runs well. Do the valve adjust, change coolant, replace spark plugs all at once.

what he' saying though is that he cant get the fuel bowl off from underneath with the battery box there. Too tight a space to work in. I can't do it either, thats why I just flip the carb. Plus its kind of hard to get the jets in and out without really being able to see what you're doing and while balancing the jets on the end of a screwdriver. Plus if you're switching main jets you gotta worry about that brass ring dropping down into the abyss behind the starter.

I expect different bikes are a little different. This is an S40. Might be different from earlier models, who knows. I'm over it, so I'll try wedging it out again. Before I ended up needing too many hands.

Voldi, can't there to show, sorry.
Wiggle the carb left and right, up and down just to loosen it a bit.
Now I forget axactly, but lift turn pull or vise versa.

Also if you're just changing the jets, you can just drop the bowl.
Get yourself a compact mirror when your wife ain't lookin', a 3" diameter is good.
Havin' a hard time getting the screws loose? use a pair of vice grips on the heads.
use a stubby straight blade on those jets and your fingers to start them.

And if you need just abit more room, take off the battery cover top.

Try spraying a mist of wd-40 around it, and listen for a change... also, check the needle slide,... is it moving freely, and is the rubber diaphragm intact and correctly seated?...
