My bike will start and idle, when i rev it up, it goes to like 6 - 8,000 rpms then it will go right back down to idle! what the f**k is the deal with this thing. i've checked all of my fuses, relays, and its not throwing any codes. does anyone know what might be the problem, let me know. even if it might sound retarded let me know so i can check it, cause i seriously think i have been over my bike 100 times!!
Thanks

 

mine does that too some times.. in process of figuring it out.

 

.... anything? im having a similar problem

 

So what. You're sitting stationary reving it up to 8 grand then it just falls off or is this when you're doing a wheelie....more explaination.

 

i am also confused as to what your question is...
do u mean right when u start it? it'll rev high cuz of the auto choke.. to warm itself up...
if u're on the gas n it drops back down. it could be **** cloggin the fuel pump or fuel filter

 

after its warmed, go to ride or pop the clutch at low rpms it'll bog out back to low rpms. and its not clogged lines or hoses its weird.

 

did u put a stupid kn filter.. or a full system on it?

 

i think the one that bogs does have a K&N on it but it never effected it before.

 

mine is problem free in AZ

 

mine falls off in a wheelie around 8 any idea???
