What size are the stock injectors on the 2004 600RR? I've been searching through google and have come up with no results. All I know is they're made by Denso.

Thanks in advance.

 

75 micron IIRC

 

Knights is correct, what are you working on?

 

i can't remember if that's for the primary injectors or the secondary (overhead) injectors though. i'm pretty sure Primary.

 

Thanks, but I've never seen injectors sized in units of microns. What is the size in terms of cc/min or lb/hr? I'm using a standalone for engine control and I was wondering what the injector size was so I can calculate pulsewidths. I have a custom IM, and I'm only using the primary injectors.

 

Really? i thought it was quite common place... but you're not looking for size though. You're looking for delivery capacity. that's information, i'm afraid, i cannot provide you.

 

Did you ever get an answer? I'm doing pretty much the same thing. 2007 TB's with only the primary injectors and a Megasquirt.
Need the cc/min figures..so, yes, the flow rate is what I need
I could care less about how big the holes are.

noobs must be all thinking alike because I was just looking at the wreaked bike i bought wondering what size injectors it had cc wise stock. Any you senior members know of a good place that would have just technical specs for the 600 rr models. I'd like to research all I can on this bike till I know it inside and out. Like I've done with the RX-7 for the last decade.

 

what’s the size for a 929 in microns?

 

I believe they are 235cc. No one in the industry uses micron size only in lab testing so it is useless info for the average backyard mechanic
Happy riding. Micron size pertains to the size of the holes the fuel squirts out of, although important info, I would assume it’s the flow rate you were looking for
