Well, I thought I would report some interesting findings. This spring I added Scorpion CF slip ons, and a K&N jet kit. Bike sounded great, and seemed to make a ton more power, esp midrange.
I noticed the tips were getting sooty (rich) so I added a K&N filter. Now it makes more power (seat of the pants) and seem to run cleaner. My mileage has gone from 30 to 40 mpg with jsut the filter install.
My jetting settings were as recommended by Dynojet. 140 mains, needle in 3rd clip pos, but instead of using their suggestion of 2 turns out on air screw, I left it at 2.5 turns as stock.
Should I go leaner on air screw or needles?
This is on a 98, whatever elevation Michigan is.
Thanks
Robb
