Picked up a Koso digital air\fuel ratio meter yesterday and got it installed today. got the brute warmed up and at idle it read between 14.7-15.1 went up and down between these numbers. so its pretty good i think 14.7 is the magical number i was told. when i give it enough throttle to open up the needles it runs real lean all the way up to 16.9 so i know i need to richen up the needles a bit. but when the needles kick in and it runs lean it takes a long time after letting off the throttle for the guage to drop back down to 14.7. the motor goes right back to idleing normally after you let off the throttle. is this normal with a mixture guage to take a while to drop back down or is something wrong. if you shut the bike off right after it drops back down to idle. and start it back up again it will go back to reading 14.7-15.1.
thanks in advance
