Be careful, that 'restrictor' may be the opposite to what you think, some of those things act as venturi by design and that in fact SPEEDS UP the air intake. So if you take it out, don't break it and be prepared to put it back after frustrating weeks of fiddling with jets and carbie and never getting any improvement ....
