K&N Lunchbox
Stock Exhaust

pilot 20
mid-main 62.5
main 142.5

Too rich.

Will change back to original.. 

EDIT: Disregard that post. There was a problem with one of my carburetors. I fixed it, but also have installed a Jardine exhaust, so I can't commend on the above setup. I will do some tests and then I'll update the post again. New post here http://gstwins.com/gsboard/index.php?topic=35237.msg493115#new

[Teek]

Maybe swap out your stock exhaust first, likely just not enough air out the back.... or try the dreaded mufflerectomy.   

Guys, a little help for lamoun here?

Doesn't sound right. That's not a very aggressive rejet. 

[lamoun]

Doesn't sound right. That's not a very aggressive rejet. 

Yes I know,  it's on the matrix but the bike is slower everywhere.. 
It's a european model with PAIR system, but that shouldn't make a difference.
I don't know, used the 60mid, lowered the needle.. not much better. I should lower the main jet now, but frankly, I don't see why I should bother.
I will just convert it to stock and when I buy a new bike, I will convert this one to a track bike and then I will rejet it properly   

[galahs]

Maybe the PAIR system is making a difference.

It isn't the restricted model the UK gets?

[lamoun]

Nope, it is the unrestricted model.

I think the PAIR system just injects air in the exhaust, and has nothing to do with the fuel mixture.
By the way, it works overtime 

[galahs]

Where's it get the air from?

It might be sacrificing engine intake pressure to inject into the exhaust... hence there is less air in the engine to burn... hence why your bike was running rich?

[lamoun]

Nowdays?? From everywhere!!  I just have the intake hose lying there, on the cylinder block. 

Anyway the only reason I can think of, is a misadjusted TPS unit, since I didn't mark where it was exactly, when i removed the carbs to jet them.

125 above sea (santa rosa CA)
40/150

RUNS LIKE CRAP fouls plugs at about 350 miles....
added one then two washers to the needle... ran worse

Adding washers makes the mixture richer -> more fouling.

I see that the wiki comments the following.

main 125
washers 1

This is entirely to rich.This jetting is for a K&N lunch box and a full exhaust system.This was to much jetting for me using a K&N lunch box and a D&D exhaust from a GSXR1000.
