just bought this CBR900RR, 98 w/11k miles on it, bike starts and runs mint .. no known mods whatsoever on it. it wont wheelie out of first gear w/o using the clutch .. it will bunny hop but thats about it .. WTF? could it be that its older, needs a tuneup etc???

Im pissed

 

Seriously dude I think you bumped your head I have never seen an RR not torque Wheelie In my life! Unless maybe your Clutches are slipping and the sudden Snap of Clutching it up Is what it takes to grab enough to get it up! Or you got to much air in the back tire and it's spinning and you don't know it!!

 

DUDE! 600's will wheelie out of first with no clutch, **** just takes practice, work on bouncin it up while using throttle. always cover the rear brake though while learnin ****!

 

Its not an issue of technique, trust me, I can wheelie a 250 ninja for miles, theres something up with this bike, could be a previous,previous owner fucked with the gearing or something, it doesnt run like an RR

 

yeah i understand what your sayin, when my clutch was facked up, i could wheelie it right when i took the bike out of the garage and it was still warmin up, but once it warmed up, nuthin, just major clutch slippage

 

My brother bought a '96 900 last year and it was the same way at 2500 feet-- no torque wheelies. Then he took it down to sea level and it started torque wheelieing on him. Brought it back home, went 2 down and 2 up, torque wheelies like a charm.

 

probley slipping clutches

 

Clutch slippage feels totally different than just lack of power (or just gearing that's too high). When the clutch slips, you hear a variance between the engine rpm and the actual power delivery. Besides, if it were clutch slippage, then it wouldn't even be able to wheelie off the clutch.

 

Make sure it has all 4 spark plugs

 

lol

 

 

im pretty sure jaxon know what he is doing.......check the clutch and the oil. when the oil isnt changed and it gets real bad it will effect the clutch......my oil hasnt been changed in about 3000 miles andd it is making it so the clutch doesnt engage all the way...especially if it is cold.....change the oil then if it is still doing it...change the clutch. then if it still wont do a compretion check on the motor cause its prob toasted and sloppy as **** on the inside, causing it to be tired and not putting out enough power.

A 900RR will power wheelie just fine....something must be screwed up with the bike.

 

it was ****ed up, previous owner tried to jet it himself.

 

So now you've got it re-jetted and it power wheelies in 3rd?

 

try checking the airbox, airfilter and exhaust for blockage.

e.g. squirrel's nest,etc.
