WTB-Semi urgent, FZR1000 main jet, anywhere

[lowlancer]

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.
Ask for a main jet for a FZR1000 they will know wether ornot its mikuni Keihen etc and will know whattype it is and will most likely have oen for sale and they are about 5 bucks max

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.

Right, I have a Dynojet kit box with the following bits in it that will fit your carbs:

FZR750 (Jap import) original main jets (Fit FZR1000 carbs) 2 x 90 and 2 x 92.5
Slide springs
Slide Needles (5CDZ5)
Dynojet mains sizes DJ108, DJ144 and DJ136. (4 of each).
FZR1000 pre-exup original mains. 2 x 107.5 and 2 x 110
4 x brand new float valves

PM me if you want them
