Tried a 7K clutch drop start the other day, but half-dropped and half-feathered it instead and the clutch did not grab at all. Revs stayed around 6-7K without any wheelspin and a very slow launch.
What are the chances I messed the clutch up?
This the first time it has happened without bogging or wheelspin.

 

The slippy feeling will stay for a while but if you are gentle with it for now it will probably be ok after then,but if you want to be a little bit aggressive with it you will kill it in a few months and and probably chatter the flywheel too.
I would,in that case suggest you to go with an after market clutch that can hold the power from this engine !!!
God why HONDA put that weaky clutch inside this car ???
