Update.....I sent my combination meter (speedometer) to AKATV and I couldn't be happier. With the speedo now working, this has totally cured shifting issues and other minor hiccups engine related. If anyone is having mysterious driveability problems, and the speedo doesn't work,  I strongly recommend getting it fixed. The service this gentleman provides is impeccable. Thank you.

I am also trying to get in touch with AKATV. I have a Honda foreman 450 that the hour meter has maxed out and odometer has changed to km instead of miles.  

welcome...what...you don't like the million mile marker ?..rofl. yes..honda came out with some kinda gadget, never seen it or used it ?..that kills the power to the meter...as the meter drains the battery. i'm not sure how it does it with the key off ?..but it does do it.

won't hurt to check the gas cap ?!..lol...lots of folks leave the knob on top of the gas cap in the off position. if its off ?..fuel won't vent to the carb. if ya get the old oem carb back ?, pull the top off (4 screws ) check the rubber piece under it for any holes/tears ?. if ya can get it to idle ?, take a can of propane ( DO NOT LIGHT IT ! )..just get some gas around the intake boot...if it idles up when you do this ?..you have a cracked, or not sealing intake boot. dirty air filter ?, clogged oem snorkel ?.
