I'd like to help with your jetting problem, but the little I know probably aint worth a squirt.
What I would like to know is where you got your dsp system from ?
Are you pleased with it? Did you get a chance to see / efeel the stainless system to compare the two?
Also where do you ride?
2000WR blah blah

What throttle position would you describe this as? This could be as simple as getting a #175-#180 main jet.
The jetting in my manual says you would have an OBDRQ needle in clip #4. This clip position would be close to too rich for most bikes. My gut tells me the colder temps and open exhaust made it lean, but the needle and clip position say DON'T go richer. What to do?? Do you currently have stock jetting? (#42 pilot/#165 main)
Try going both out and in by 1/4 turn on the pilot screw, this is slightly below the range of needle clip. Then check the needle code and clip position. Possibly try clip #3 with the OBDRQ.

remember we live on an island & the air is VERY moist. this leaves less room for oxygen correct? so come down one main jet if not two.
our pipes are more open than yours standard so again we don't need tthe giant leap for man kind!
sounds to me like lift the needle one clip.

Yes, leaner for moist air. Richer for sea level or cool air. Things offset if it's cooler.
The main looks small already with the "D" needle. Many would be using a 175-180. The needle would be in #3 in my bike with a free flowing exhaust.
BTW, here near Seattle Washington it is also wet and near sea level. There is moss on the roof and no dust for the next 7 months which is fine for me. The mud gets heavy but gets washed off in the water crossings. Rust is a big problem for the wheel bearings though.
