help with derestriction of cbr 600f 2002 fuel injection

[fintan]

can anyone solve this riddle for me? i have removed what appears to be a restrictor plate from the end of the throttle cable but the whereabouts of the 4 washers in the airbox illudes me. there are def not there. do they always be there or can it just be the plate. any help would be appreciated

May well be between the carbs and engine, in the inlet rubbers.

With the airbox off, if you open the throttle full so you can see past the butterflies, you should see a black hole, if theres a silver plate in there with a smaller hole in, thatll be your restriction.

Just a matter of undoing the clamps on the inlet rubbers that hold the carbs on, then peel back the carbs and pop the washers out.

EDIT: Fail for not reading the title and noteing fuel injection!!!

Might well be worth looking down the throttle bodies to see if there is any form of restriction there. But itll most likely be in the form of a different 'restricted' ECU or otherwise.

If there are washers, they'll be in the bottom of the inlet rubbers, closest to the cylinder head.

Some of the bikes are restricted at the ECU. There was a guy on here called p0peye I think, and he had to change his ECU. Don't think his was a UK bike using an FI International kit though.
