OK, guys, don't laugh at me, although this may seems weird.
I installed the D&D slip ons on the 08 Scrambler. It starts easier than with the stock pipes and jets and it runs great . The engine is a lot more responsive - it has really transformed the riding experience since it sounds and runs so much better. Pilot jets are now 45, old ones were 40. 3 turns out on the pilot mixture screw
Here is the strange part: After first starting up, the exhaust from the left cylinder gets warm pretty fast. The exhaust from the right cylinder almost feels chilled since it is cooler and has a lot of moisture which makes it feel cold. Both headers warm up pretty fast, but the gas is cooler on the right. This is both at idle, and more important at about mid-revs. Sorry, no way to measure temps at either location at this time, just holding my hand in the exhaust stream.
After warming up the bike, the exhaust from the right warms up and is dry, but is still noticeably cooler than the left.
I turned the mixture control screw in on the right carb to see if I could warm up the exhaust gas. It warmed up a little at about 1 turn out, but the engine didn't run as sweet at mid throttle. 1 turn out has to be too lean anyway.
My first thought is mixture, since exhaust gas temperature is how you lean an airplane piston engine. The mixture screw doesn't make much difference though.
Any other ideas?
BTW: the slip-ons are sealed well at the joint, the bike only has 800 miles on it...and I can't tell you if I had this condition with the stock setup....
It runs great, but I think the bike may be telling me something.
