Tired of wearing ear plugs, like the stock sound now,
But I have a 40, and a 128 main jet, I think I need to go back to the 35.
How many turns out should the a/f screw be now? I have all the other mods done also
air box, slide drill, etc. etc.
Can I get away with a 125 main?
Also what position should the clip be in on the needle?

Thanks for any help, Joseph

 

I ran stock with it drilled out (NO NOTICEABLE SOUND DIFFERENCE, but it opened it up a bit,) I run kdx air snorkel and had wonderful results with stock idle and 128 main, DJ kit 2nd groove. 2.5 turns out.

 

I checked my old jett's that are in the bag.
It looks like I have a 125 in the bike now with the 40, I turned the a/f back to 1.5 turns and put the lid on the air cleaner, no snorkel.
I ran 20 miles and checked the spark plug, it wasn't black at all.
I guess I am o.k.
I will have to check the plug it in a day or two.
