Hello guys, i believe my valkyrie is running a bit rich on the low band, im thinking about messing with the pilot screws a bit, i rebuilt my carbs about 5 months ago when i got the bike and i cant remember how many turns i gave it probably what i read here o the forum i was thinking about giving it half a turn IN and see how it runs.

I've cut slots on the back of the screws so i can use a flat screwdriver on it BUT.. whats the best and easy way to get access to it? i was thinking about removinf the intake elbows but i thought i would ask you for an advice.

As long as you have slotted the screw heads there should be no problem getting to them and giving them a twist.

Since they are now so easy to screw, I'd recommend just a 1/4 turn to start with.

I always remove my intake elbows. I have big hands and fingers. Loosen everything on both sides first. Gives carb back more play, so they pop right out. Check your hoses or nipples on your intakes why you there and also your orings. This way its easier to get an accurate setting.

I have no problem getting a tool in there to turn the screws, I remove the spark plug boots and vacuum caps to give room to maneuver the tool. If you have big hands and fingers like Roid, there is always something like this...

The pilot screws will have very little affect on what you think is "rich" running. Look elsewhere like the jets and needles, and the  air cleaner.
