Guys,
I recently installed a HMF utility pipe, K&N Filter. I removed the carb to rejet and adjust the fuel screw. It runs alot better now but I know have a speedometer issue. My speedometer is definately off. When I slow down and come to a stop it will still say like 5mph for a second. When my speedo says I'm doing 40mph I am probably doing only 25 then when my actal speed catches up it seems like it is reading right. Still tops out at 58mph WOT. I tried doing the ECM reset procedure and it did ehat it was supposed to. (I heard the thing adjusting), Any other ideas on what could be causing this? All I disconnected on the carb was the vent lines and the sensor on the side of the carb. I left the choke cable and throttle cable attatched. Thanks for the replies.

well your tires are 2 sizes bigger than stock where the spedo was calibrated at. Maybe that is it or did it work after the tires.

It's not the tires. Like I said It happened after I took off the carb

i think that it just went bad, i dont think it has anything to do with you taking the carb off.
