I took the tank off my 640 Adventure and there are 2 or 3 wired connectors that don't go to anything. Does anybody know what they are for? Also, I get about 250 miles before I hit reserve with 157.5 main jets, stock gearing, does that sound right, I always here 300 mile range are you counting the reserve also? Any recomendations on gearing and suspension settings. I tried a 15 tooth front but it seemed too short on the road, great for off road. The suspension is great but it seams the rear kicks up over small jumps unless i'm hard on the gas. Still new to the whole dirt thing but enjoying it more every dirty mile.
