help on a vibration
Guys need some help i got a 07 gsxr 1000 motor in my fb car i been having a vibration at higher rpm's i check ever thing in the drive line for any loose bolts so far nothing loose someone ask me to check the clutch basket anything being crack off it looks fine i check the chain for any tight spots and the crazy thing is if i take it easy it 's ok if i hit gas hard and get 6000 rpm or high i have to let off the and ease into it Thank;s for any help
Are you running a slipper clutch..
....is it slipping under load
what happens if you kick in the clutch and get out of the gas when the vibration happens........is it engine or chassis related?
Could the vibration be a misfire? Will it happen just revving the engine while not moving?
Are you sure it's RPM related, and not speed related (ie. it happen regardless of what gear you have selected). If it's gear dependent perhaps it's related to the gears, or some other driveline component (you mentioned checking chains and sprockets) -- what about CV joints, hubs, tires or wheel balance.
If the problem is speed related, perhaps it's an aerodynamic vibration with a broken wing mount or similar.
I'm with David, knowing if it's RPM or speed related is next since it sounds like you already did a quick check for anything obvious.
Re: help on a vibration
What rpm does your clutch engage ? Hard on the gas = vibration. EZ on the gas = no vibration.... hmmm ? A weak ignition system can cause a misfire under heavy load....

Check CV cage's for cracks. Also make sure the front and rear sprocket's line up with a strait line.
ok thank's I look into that I sure the diff is ok but I will check the cv's
