Just fitted a 33bhp restrictor kit myself that I got of someone who used to have their cat restricted

The washers went into the inlet manifolds like they are meant to

Went out a ride and in first gear it revved up to 12k. Is this normal?

I know the washers are in there and they are for the thundercat I dont see how they could have came out though :S

any ideas??

Cheers
