As title says, I need a single main jet for a Yamaha FZR1000 set of carbs.
They are going on a Mitsubishi 4G63 car engine which is still a wee way away from being ready but I'd like the carbs to be finished and ready asap.


Cheers guys

Hey Man your best bet go to a bike shop.

I may have some mains floating about for the '87, '88 FZR1000 Genesis.
What model are yours from?

They're Mikunis

Unsure what model, bar that it was a non ex-up. I'm redrilling them out so the size of the internal hole isnt important, as long as it fits the holder

Bah then that should be dead easy. Mikuni is like Keihin -- for 95% of their carbs (not OEM specials) they just use a small range of different jet types and just offer them in a number of different sizes. Take a look at this page: http://www.motorcyclecarbs.com/Mikuni_Main_Jets_C15.cfm Your jet style is probably on that page somewhere. Most bike shops (Henderson Motorcycles had plenty of Keihin varieties sitting around) have probably got the appropriate style in a box sitting somewhere, maybe $7 for one jet.

Got any other bits? My stunt bike is awaiting it's next transformation, so some bits might help me decide exactly that transformation will end up being.
