Jets and Hyabusa pistons
 

Where can i get a 136.5 jet from?

Also, do standard Hyabusa pistons fit standard bore of a 650?

What carbs for[1]? Most places I believe drill the jets rather than actually get them in such increments.

IIRC they just need a hone.

[1] Different makes have different scales.

What drill them! bloody hell.

did the sv have different carbs then?

Re: Jets and Hyabusa pistons
 

Yep, easier than carrying a load of jets. I personally prefer to swap jets but hey ho.

Original Mikuni carbs then rather than Kehin flatslides was what I meant. :)

Do you know which type jets they are (I've avoided doing jetting on my SV personally), N100/604 (large round head ~8mm), available #50 to #180 in 2.5 increments or N102/221 (small round head ~6mm) available #50 to #200 in 2.5 increments.

Or N100/606 (Very small ~4mm head) #30 to #150 in 2.5 increments.

What do you want 136.5 jets for? Way small.

They're the small head ones but the big head ones fit too.

Try http://www.allensperformance.co.uk/mikjets.html

Never used them but they list them.

I buy jets from them, fine place to deal with.

Re: Jets and Hyabusa pistons
 

they are Mikuni carbs,

bike was running crap, due to bending a valve last year so i put a 3000 mile injected in running on carbs,

Steve jordan set it up on the dyno, and said should go 1 size down and 1 up on the needle!

But i don't know what size is in the carb.

Re: Jets and Hyabusa pistons
 

ok what mods are done to bike.

Re: Jets and Hyabusa pistons
 

Its a minitwin spec carbed bike with injected engine.

Hayabusa pistons not legal for minitwins.
