1st time this has happened......

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)

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!

a week or two? that's a long time to leave the bike at the shop for an hour of labor

yeah, well he has to wait for the part to come in. if i kept it at home i'd be entirely too tempted to ride it, and i dont want to do that w/ the mileage not working properly....i want to have the correct mileage showing, ya know?
 
maybe my g/f will let me ride HER F4i!!!! that my CBRForum friends is reason #179 why it kicks ass to have a g/f that rides!

There out riding it right now There is no reason that part should be more than 4 days out.

You're starting to sound like me!!

When my bike was in the shop for 3 weeks after getting rear ended, I even went so low as to borrow my roomates GSX-R hahaha


Glad it's getting fixed and not too expensive.  When you get it back.... time for a roadtrip!

i have the same problem.  been like that for 2 years now.  I know it's the speed sensor.  but i won't bother changing it cuz my mileage doesn't go up.  Someone with a new bike should really consider damaging the speed sensor on purpose to keep the miles down.  When reselling, just replace the speed sensor and make more money.  $100-$150 (labor already included from shops) is a lot less than selling your bike with thousands of miles.  hehe.  just don't be stupid and try sell the bike at 0 miles 3 years later.

and you should really consider standing in traffic for being a conniving, deceitful prick
