Can anyone help with a supplier or know of someone that can supply a complete 33mm Flat Slide arrg
Also looking for a supplier of parts , bikes etc .

SCB had a set a year or so ago - might be worth a call.

Mind you need the black box too.

Pretty sure Allens Performance will do you a full bank but it'll likely be dearer than the rest of the bike's worth.

...and won't have the added zxr bits (the potentiometer up top and sensor/solenoied/whatever-the-hell-it-is back in the accelerator pump system).
Definitely the place for parts though.

A mate had a FZR400 with a set once but I don't know if they were standard or had been fitted by a previous owner. They didn't have the extra gubbins either.
