help with downtown 300 issue

[roboscoot]

i have a 2012 dt just over a year.....have had no major problem since i bought it...all maintenance done on schedule.....heres what is happening.....the speedometer reads like 50 when you are only doing say half of that....on idle the speedo shows about 20 mph....and correspondingly....the tach is way off as well when on start/idle it revs at 3900rpm...

if you just turn the key on (without starting) the pointer on the speedo is at 20 and the pointer on the tach is also at about 20.....so when riding the pointers are at higher levels than they should be so i am working at higher levels on speedo and tach....

believe electrical....i do charge with trickel charge as needed.....have noted the scooter will stall out at times if not warmed up....other than that power still there but not  reading the way it should......anyone have any ideas/suggestions as to what might be going on?

I had this with the instruments after I blew a fuse. Turn the key on and let them try to find home. Do this several time and each time they should get closer to home. As far as the cold stalling, try reseting the throttle position sensor. There are several threads on here as to how to do it.

racewalker.....i don't have any blown fuses....everything seems to be working..re electrical......but what i did do....was adjust the throttle just a tad...and did what you suggested...turned the key on and off and noticed each time i did this the pointers on the instrument panel got closer and closer to where they should be ...after about 4 trys got everything back to normal......than rode the scooter this am to check indicators ....under riding conditions.....everything is fine.....will continue to monitor...and thanks for your help.....

I had this same thing. What I found worked, was I was going down hill, turned the key off, then back on. Compression started the scooter back up, so I didn't have to stop. Had to do it about 4 times too. Was about 8 months ago. Hasn't had any problems since. Mine showed up after I removed the battery to charge it after it had drained.
