help 02 12r
Does anyone actually know how the 02 12 was restricted?
It's said that the bike is restricted via the odometer.
It is also said that a pulse is sent to odometer via the countershaft trigger(also along to the ecu)
1. What is actually happening when the bike is going into restriction mode?
is...
a. fuel reduced
b. spark cut
c. rev limiter initiated
My odometer isn't working. My fi light comes on after reving past 9k rpm. If I turn the ignition (off/on) it resets
If the odometer isn't working what is the outcome?
The problem I am having is, my bike is running lean on the big end of the qtr mile. The mods are gearing, muzzy pipe, arm, lowered, pc3r.
60 ft avg 1:54,1/8 ml mph 116, 1/8 et 6:30, 1/4 avg 9:83@ 137mph. (all motor)
When I say lean, I mean lean. The pipe turns white on the inside>
I have disconnected the pc3r and run the same times around the same mph. I have swapped pc3r to a pc3, with the same effect.
no difference.(what are the chances that both are bad)
I have checked the fuel pump and even swapped it out(same result)
Around town doing normal riding the exhaust pipe is black, but when I make full throttle passes at the drag strip and at my testing
site, the pipe starts to turn white, reguardless of the fuel table settings.
Possiblities: fuel pump, fuel regulator, pc3(r)or odometer not receiving signal and shutting down fuel.
I think this is happening after 3rd gear. The bike seems to fall off after the 1/8 mile.

I guess when you say "white" you mean the outside of the pipe, near the head, right? I wouldn't expect you to mean the tip of the tailpipe. Getting white there would be odd. Almost making me wonder if it's from radiator fluid making it's way to the combustion chamber or exhaust. So, I'm assuming it's the head pipe.
Anyway, if the bike works well around town, seems good in 1st gear, sometimes good in 2nd, or maybe sometimes at the top of second it starts to show a problem, and then in 3rd and 4th or higher the problem is there always, that sounds like fuel pressure.
That's my only thought. If you haven't done it, it might pay to check the main and return lines for any kinks. There's also that very off chance of a clogged filter, but that certainly wouldn't be my first choice.
I've heard that on an electric pump, you can clock the amount of time it takes to make it fill a 1 gallon jug. Use that time to figure out 'gallons per hour' to see if it's up to spec. Sorry, don't know the spec!
You can lift the tank and remove the return line from the tank (red label) to fill the gallon jug.
Unplug the black fuel pump relay at the front of the tank. (has brown plug)
Jumper the RED wire with the White/Red wire. Turn on the key and the pump will run.
PS. don't apply any power to the brown wire on the plug or you'll kill the ECU.
I got the 12R fuel pump stuff directions from an old post here.......

BA,
No, it's the tail pipe. white tail pipe on pump gas mean lean condition. If you didn't notice when you removed your stock header the insides were white. I was thinking along the same lines as you are (low pressure or not enough fuel).
Put the bike on the dyno yesterday, with help of FastestR1 and got the problem solved.
ok, for those that looked at this post, here's what I found out yestereday.
The odometer wire(pink) was the cause of the lean condition. With the wire connected the bike pulled it's normal hp range of 166 to 169 with the muzzy pipe/pc3r/stock filters. The idle was a/f of 13 to 1
I made several passes, then changed fuel tanks(thinking it's the pressure regulartor), with the new tank(fastestR1's) the bike pulled two ponies over my tank. The idle was 13.6 to 1
Out of couriousity, I disconnected the pink wire and what would you know, this was the cause of the lean condition. The idle was 13.9 to 1. We did another pull, there was a premature rev limitation. It kicked in around 10,850 rpm or so. Normally the bike didn't hit the limiter until 11,700 rmp.
So, there you have it. The final test will be this Friday nite at the Hawaiian Race Way Park. The fastest I have managed was a 9:80@137 on motor. 60ft 1:52, 1/8 mile: 6:30@116(spinning).
If this fixed the problem, then the bike should run some 9:6ish around 142 mph(210 lb rider)
