Hi, has anyone had trouble with the idle mixture D type screw not adjusting at all I purchased the correct tool to do the job but both screws refuse to move ! the tool locates OK but how much force is needed to adjust these things.

They should adjust very easily - they should not be tight at all.

Just did that today with a "D" tool, OldBiker. Turned quite easily. If you are positive it is seated correctly, give it a good tweak with thumb and forefinger. Perhaps it is just a bit "set" from time.

Or old fuel that has turned into varnish.

Nope tryed again this mornin apart from putting some grips on the tool (joke) both mixture idle screws don't want to move, I purchased the the Bonneville when it was 1yr old in 2006 I don't think any one before me would want to adjust them the only reason I need to adjust it as I've put old styled silencer and rejetted on Bonneville

Being spring loaded,something is wrong.2 fingers should be all it takes.

binding

Any chance the tool is binding on the side of thehole? Try cleaning up the tool with steel wool, maybe put a little lub on it too. Just a thought, I know with a screw driver on mine, if I'm off a little on the angle, the screw driver will bind on the hole side, HTH's

Hoopla

Very weird, should not be happening. Sure you're turning them in the correct direction? I know that sounds retarded but sometimes stupid suggestions make for the easiest solutions.

That can happen from time to time with the Bella Corse D tool, as the D-shaped socket is relatively shallow.

Tryed again today for the third time and guess what's happened the D tool is F**%$D

I first made my own D tool from a bit of pipe from a long air nozzle - had the right ID and OD. Used needle nose pliers to bend the D shape and wrapped duct tape to thicken the base for a good grip. Worked okay, but the "genuine' thing from newbonneville worked better. I just adjusted my carburetors to 2 3/4 turns out - pretty exact with the tool, and man, the bike hums sooo much better than before. My home made job must have allowed for too much slop. $16 a bit pricey - but good tools for a good bike, eh?
