took my bike out for a chilly ride this morning and i get halfway down my road and notice im doing "0mph"........when i was easily doing atleast 45mph and my mileage wouldnt budge. i pulled over, turned off switch, turned the key and did it again. the speedo did its normal things, nothing out of the ordinary but then as i started riding it stayed at 0 again. so i turned around to head home and as i downshifted for a turn, the speedo jumped up to 30, then went through random numbers like it was trying to keep up w/ me going from 30......10.....3......38....ect. it was almost as if it needed to be warmed up because i went back out and by the time i got to where i was going (8mins away) it was working fine and did fine all the way home.

anyone else have this happen to them? i mean, its working fine now so "if it aint broke, dont fix it".......but it seemed as if the guages were cold, lol. i let the bike warm up before i left to about 120 and its in the low 50's this morning.........idk.

 

Almost sounds like a speed sensor going out. I've heard of a few other people having speed sensors go bad on their F4i's. Not terribly common but heard it a few times. I don't have my service manual with me right now, but I would imagine there is a testing procedure to check it to make sure

 

nice.....expensive?

thanks for the quick response Jared. i hope all's well at the new casa! hey, now you're closer to MD!!!!!!

 

when you first start up the bike, does the speedo cycle through 0 to 180 mph? And does the needle on the tach go from 0 to red line and back? I think that is what will tell you if there is something wrong or not with the speedo sensor.

 

EHonda, yep.......it does that. goes through its cycle of normal things.

 

Hey you said the milage doesn't budge? That's good for resale!!!!!!! lol I don't know about the LCD being cold for it to not work usually if it's cold it will just be really dim or be missing a line on an 8 or something if you know what I mean. I found this link on another great site http://cbrworld.net/forums/thread/279024.aspx

Good luck!!

if it is infact the speed sensor, its about $80-$100 new...u might be able to find a used one cheaper(ebay or somethin)...its in the right crankcase cover...right next to where the clutch cable goes....look for a red cable connector that comes out of the crankcase....its a short cable so its hard to connect/disconnet. (unless you got really tiny fingers)

 

+1

 

WTF!!!!!! its doing it again this morning!!!! everything on the guages works fine on startup (rpm needle/mph cycles through numbers) but when i start moving........nada!

 

thanks everybody for all you're replies! i just dropped the bike off at a local shop to have it fixed. the guy told me the part was about $50 and it'd be a half hour/hour of labor. so its not going to be terribly expensive. im not the best mechanic so i left it to them. idk how im going to make it a week or two w/o my bike. lots of CBRForum posting and crying at night, lol.

thanks for the input everybody!
