dumped the bike for the first time today in some really tight trails. nothing hard more just lost my balance when i came to a dead stop and laid the bike on its right side. anyhow now my speedo isnt working right my rpms seem to be right on the money but when i was doing between 50-60 mph with my friends riding next to me my speedo was bouncing between like 30-40 and wont stay steady even though im holding steady throttle. any ideas on if i should replace the cable or the pickup at the hub or just finally suck it up and buy a vapor kit for it?

im kinda lost on this one so if anyone can offer some help thatd be great

 

and if i should just buy the vapor kit i was told to get one for a klx 300 so would this be the right one?

Probably the cable. I've broken mine about seven times.

 

ii pulled it off from where it mounts to the gauge and it doesnt appear to be broken at all and same thing down at the hub

 

bump
ive decided im just going to go with the trail tech kit as ive been wanting one anyways. but i want to make sure that the one im looking at will work being that they dont actually make a kit for the 250s

Crimping the cable sheath will cause similar results as you are experiencing.

 

i swapped it out with a brand new cable and its still doing the same thing

 

sounds like the pick-up at the hub is busted.

 

There's friction at work somewhere. Probably at the hub or the display. May have put a slight bend in where it connects at either end - that would cause a wobble, and hence, a bouncing needle.
