Pilot screws Stuck

[Wildman]

The last year I adjusted my pilot screws one of them was stuck.
Yesterday 3 of them were stuck.
I split the brass D drive on my 90 degree screw driver.
The steel D drive with the knurled thumb wheel can handel all the torque I put to it.
I can bearly budge several of the screws.

Does any one have experience with this?
How do I free them up?
A little liquid wrench and twist both ways till free?
Buy new pilot screws and drill out the old ones?

The bike already runs much better with the carbs balanced but I'd like to get the cylinders as even as possible, and pilot adjust is part of that.

Whats the best pilot screw setting?
2000 standard
6 degree trigger wheel
K&N air filter no prefilter
Interstate carb springs

Ive heard from 1 1/2 to 1/ 3/4 turns should be good

while I'm at it should I go for the 38 slow jets and maybe 108 mains?

I will be polishing the inlets and maybe adding the ECT timing mod.

I'd like to get better milage performance is secondary but would nice to have.

Thanks for any advice. Wildman
See you at Inzane

Well, if you are (honestly) looking for better fuel mileage - larger jets are not the way to go!

Sounds to me you are a closet speed freak tho'.  Just like me.

I love to tweak the bike and surprise all my friends when I lose them in my dust.

What did you do, they would ask. I would calmly deny any improvements and tell them it's their lack of rider ability. Haw Haw!

Next week it'd be their turn to, turn the tables.

Hi Rick

Yes I am a closet speed freak. I got the Valk in 2002 because my thinking half won out over the speed freak that was eyeing a Hyabusa.

You could try a little heat and more solvent ,but, flames around carburetors can cause problems at times. ..  If you can get them to turn at all then just keep them wet and keep turning them back and forth until you get them out.. You may have to take a dremel tool to them and cut a slot in them for a normal screwdriver. The wheel will cut into the housing a bit.. I slot all the pilot screws and add a dab of neversieze to threads.. As for the settings, I like 2.25 turns with 35 jets and apparently 1.5-1.75 works well with 38's.. I don't have a problem with 38 low jets,,but,, I certainly wouldn't install any larger  high/main jets..
