Re: Cbr 954rr-attention fireblade friends- need help

Hi!
You are sure the codes are 1 and 2 not 12? (long blink and 2 short ones)
One long blink is 10.
That code 12 would indicate a injector fault.

Also how you ended up forcing air into that vent tube?
Sounds odd.

Actually asking for my husband- he said he forced the air in the tube just for the he'll of it, used his compressor and it DID sound way better. He thinks he knows why now (trying to remember what he said) he needs to remove bolts and reeds on par system and block something off so it gets air- sorry if I phrased anything wrong. He's been trying to get the thing running for a couple years now, one problem after another. Trying to figure out if all the hoses are correct- vacuum, air,coolant hoses to the wax unit etc.

Have you checked compression on all 4 cylinders?
If not do that. It'll tell a lot.
I highly doubt that the pair valve system is the problem here.

As of know has to be on full throttle to run at all, barely starts- doesn't rev at all and dies immediately no matter what throttle position it's at.

I don't want to seem a wise ass, but there comes a time when we must bite the bullet and take our bike to a decent workshop. My feeling is that if we cannot solve a problem after a few online tips, well, it must be beyond us and therefore time an experienced technician to step in. Sure, budgets can be restrictive, but a small cash outlay can compensate for hours of stress and non-riding.

Ouch haha you're right. Worked on my buddy's Shadow for maybe 2 days straight. I made it a skeleton and brought it back; fixed nothing. Twice.

Even the shop has been at it twice.

Sometimes you gotta try two shops.

On the subject of Carbs, Ian, I get a strange pleasure from people doing stuff like this:

CARBURATORE CNC TCR - CRISTOFOLINI Racing

And, even though I would not do this with them:

CRISTOFOLINI Racing

I understand why someone would!
