The #55 pilot did the trick. Silence on shutdown and nothing but rumble on the decel. Actually kinda sounds like a Jakebrake on a semi-truck. 8) The only obnoxious noises comming from it now are intentional. Thanx to all that helped.

It took me a couple trys to get rid of it but I finally did. I took Lancer's advice and after the new pilot, started with the screw out 1 turn and went from there. Actually wound up being 2 for me.

I bought the #55 a couple days ago. I took a quick stab at getting the old one out, but didn't have any luck before my buddy showed up wanting to go for a ride.
Supposed to rain for the next couple days, so if I get my income taxes done, that's the next on the list.
Any suggestions on getting the old one out? I think I'll pull the entire carb so I can get a better look and more leverage. Did yours come out real easy?

Take the carb off the bike to work on it for this.
Take the top off and remove the spring/slide so the carb can sit flat on a work surface upside down, exposing the main and pilot jets.
Find a screwdriver that best fits the pilot jet, then take a small hammer and GENTLY tap on the top of the screwdriver while applying turning pressure to unscrew the jet. It usually does not require much tapping or turning force to break it loose and will work 99% of the time.

REMEMBER...GENTLY

Yea thats right, lefty loosey/righty tighty. I was too lazy to take carb off but I have a set of screwdrivers that fit the carb stuff perfect. I just loosened the clamps on the boots and rotated the carb. The bowl screws were actually harder to get out than the pilot jet, and I had thm off before when I changed the main. I did the main the same way. I would suggest doing it the way Lancer suggested though. Bound to be easier on the neck that way.

Got 'er done.
Not the taxes.....
The pilot jet.
Priorities, that's what it's all about.
Stopped raining long enough for me to get it all done and then started raining again, Sad

So I haven't had a chance to really test it out. Just playing with it in the garage it seems to pull harder right off the bat, and zero backfiring from revving to cut throttle. Idle mixture screw at 1 turn out and she idles steady and strong. I went out and bought a cheap screwdriver, and shaped it to my liking, With carb in hand and a little force, the pilot jet came right out. It's not going back in, that head is butchered. I cleaned the hole and threads with a Q-tip, to get any pilot shavings out, the carb threads were perfectly fine, which was a big relief. And the new pilot jet screwed in and seated nicely, another big relief since I bought the jet from the local HD dealer, and it looked quite different. HD was my last resort as the local Suzuki/Yamaha Dealer were too busy trying to upsell me on a jet kit, and the local Honda/Yamaha were too busy to give me the time of day, even though I was in there all the time with my 250 Rebel. Dang, I keep forgeting about the spark plug door mod. Oh well another time I guess, gotta get those taxes done.
Thanks guys.

Pics of my jets:
The taller one with the thinner neck is the new Official HD engine part (Made in Japan). And has 55 stamped on the head The other one is the stock jet and has 52.5 stamped on the side

I was afraid that head would not fit into the tube, but it went in beautifully. Also forgot to mention that the battery box on the S40 made getting the carb out a major hassle, Were the Savage battery boxes that close to the carb? Clymers said to just pull the carb back away from the engine, but the battery box is almost snug up against the float bowl. Getting it back in was much easier as I left the bowl off, being extra careful not to touch the floats themselves.
Can't wait to get out and test ride it. I hate drizzle!! Just rain and get it over with.

You can try the dealer for the main and the pilot. They may have them in stock. Just so happened that my local dealer didn't have a pilot. I got mine from a member here on the site. He had ordered a pair from http://www.denniskirk.com/ .( I think they only come in pairs )
