Hi Mark
In yanky land they call a fazer 1000 an FZ1 . So if the lever your looking at is for 2001 to 2005 it should fit fazer 1000 m/c . The later and current model came out in 2006 known in UK as FZ1 naked model and fazer faired model. Confusing I know.
I have tracktech levers on my fazer thou 2005 model . I got them from 'Buster's', I forget how much they cost but you could google it.
Obviously you would have to buy a pair but then you would have a spare clutch lever.
The quality is good for the price, mine have been on five years no issues.
I once owned a RD350 YPVS N1 dream machine painted Kenny Roberts colours, it was Stan Stephens tuned with F2 pipes made by Stan . It flew!
Hope you find your lever
Cheers Jacko
