reverse light flashing

just finished cleaning clutchs and after putting it back together I started the bike and reved it up to see if everything was working properly, when I looked at the display I noticed the reverse light was flashing, can someone tell me off hand what that means.

the same thing happened to me when i first got my Griz, the problem went away before i could find out what happened.

Q: what year is your bike ?

Q: did you install a reverse over ride, is it on ? ( The reverse indicator

will not function with this mod. )

not sure about this, don't have my service manual handy but i think i read somewhere that if the reverse light flashes it might be the speed sensor? if i am out to lunch here someone please reply.

I noticed mine doing that and it turned out I didn't have it latched into park all the way. When I mashed the brake and tugged at the shifter it clicked and the blinking reverse light went out.

I noticed the same thing. I would rev the engine a little after it warmed up and the reverse light would flash. The handbook stats that is the problem in a round about way so I did not worry about it. It stats that the reverse light flashing is an indicator of the speedometer not reading correctly and to take it in and get it serviced. yeah. don't think I will be doing that.

I had my 2006 Grizzly do the same thing while idling the other day (first and only time it has done that)... The problem went away when I turned off the bike and restarted it. I wouldn't worry about it unless the problems occurs every time the bike runs.

I did have the bike run for a while with the choke set less than halfway for the warmup. If you run the bike too long with the choke just set enough to interfere with proper idling, could this cause the flashing light ? I'll have to see in the near future... got some cooler weather coming my way (Quebec is known for its cold winters).

I just had it happen today. 2005 Grizzly. Went though some real deep water quit a long distance. First the speedo read zero and was stuck there, then not long after the reverse light started flashing. I drove it about 5 miles back home on the back roads, and it must have dried up as the speedo started reading properly and the light stopped flashing. All is well now. So definitely speed sensor related.
