[ECU failure??? Or something else???]

Changed the FPR. Now xx consumes 5.5 liter per 100 km. Less than should Thank you for the advices.

[Rear brake doesn't work and problem with fluid]

It was a air lock. I bleeded the brakes again. Looks like 3 years ago I have forgotten about one nipple. Now everything works fine! Thx a lot for advices.

The FPR vent lines should be bone-dry; any residual fuel--even moisture--is a sign of a compromised FPR diaphragm, a pinhole would do it. This is one of the few weak spots in the XX. The original (FPR) design predates the proliferation of alcohol-laced unleaded fuel, which is thought to contribute to weakening/compromising the diaphragm; anecdotal reports, while falling short of empirical evidence, seem to support this conclusion. Fortunately, the fix (replace the FPR) is relatively inexpensive and easy to do (on the right end of the fuel rail).

You don't wanna fuck it off.  The gas all goes to #3 cylinder and can lead to a really bad time.

What is an average lifespan of FPR?

How quick FPR failure can lead to ruin the cylinder wall?

[Rear brake doesn't work and problem with fluid]

Maybe it is important. There is no fluid in the secondary master cylinder (near the left front fork). Air inside only. Looks weird....

[Rear brake doesn't work and problem with fluid]

Thx. There is no resistance at the rear brake lever. What is it?

Take the cap off the rear fluid reservoir, that should let it flow.  Beware that if you get air into the linked part of the system it'll probably be a bitch to get out, be cautious about which bleeders you open and what you do.

I did it, but nothing goes out from the nipples. I followed the Honda user manual 😕

[Rear brake doesn't work and problem with fluid]

I'm trying to pour out the fluid via the bleeding nipples on the rear caliper, and no success.

Hi

 

Maybe do you know what failed. Have no idea.

 

I have standard linked brakes. No mods.

 

When I push the front brake lever, the front brakes do work, but rear one not (pistons don't move, even a milimeter).

 

When I use rear brake lever, the rear brake doesn't work and the front don't.

 

Also I can't remove the fluid from the rear brake reservoir, while there is no problem with emptying the front brake reservoir.

 

Thank you in advance for the advices.

 

Cheers!

Was yours leaking?

I haven't checked yet :)

Hi

 

The problem with voltage was in the connectors. Some were seized. Cleaned them and voltage is ok now.

 

I have ordered the fuel pressure regulator. Thx

 

I don't have O2 sensor, while I installed power commander with O2 sensor eliminator.

Hi

 

It is my first post here

 

My XX worked not very well last time. 20 000 miles done. Year 2002.

 

Fuel consumption was horrible. I could do only 90 miles on a tank driving very calmly!

 

I checked all the sensors and noticed that the voltage, which is delivered to the IAT sensor (is in the airbox) and to the engine coolant temperature sensor is only 0,44V ! Haynes manual says, that in both cases it should be between 4,5 - 5,5V.

 

It is possible that bikes consumes so much fuel because of it. Manual also states that when low voltage is present, the ECU can be damaged. 

 

What should I do now? Maybe the manual is wrong and you had similar issue? What is the reason of it?

 

Thank you in advance!
