2006 Speed Triple Problems

Is the MIL (malfunction indicator light) on. If so you need some software to read fault codes.

 

Possible blockage in the exhaust.

 

Crank position sensor?

 

Did you also replace the fuel pump hoses in the tank? I had an -07 that had similar issues and that turned out to be the problem even though they looked fine.Also check the wiring harness around the steering stem, they are prone to breaking wires around there. I also think I’ve read a bad ground giving people similar trouble

 

put your hand (gently!) on the exhaust headers to see if they are all the same temp at starting?
If not, you’ll have an indication of which cylinder is playing up.

 

Plugs. Check they are correct spec ones, if 1 cylinder is dropping out try changing plug over.
Vacuum hoses. Did you use OE ones or silicone, if so are they vacuum quality, if not, change, Are they connected correctly,?
Coils. Are they new or used replacements?
Valves. Are you sure you have done them correctly, some people seem to get it totally wrong. Cam timing correct, loose chain could have slipped one tooth?
Cps sounds unlikely but don't write it out completely.

 

There are a few faults that do not illuminate the MIL so it would still be useful if you could check for any diagnostic trouble codes. Is the small diameter rubber hose connected to the underside of the MAP sensor? The MAP sensor is attached to the top of the airbox and should have an electrical connector plus the hose which connects to the throttle bodies. I assume you also have a new air filter so there is no blockage in the intake system?

 

Perished O rings at injectors?

 

You have gone through so much that you might be at the point where you have to measure the fuel pressure under load on a dyno. Then at least you’ll have it narrowed down to a fueling or electrical problem

 

Those codes all indicate wiring faults / short circuits and the MIL should have illuminated. It is possible that only one wiring fault has triggered multiple codes.
The codes relate to the MAP sensor, stepper motor, secondary air injection, ignition system & throttle position sensor. I would start by checking the wiring where it passes the right hand side of the headstock as this is a known weakness where cables can rub through. Then I would check the ECM connector pins and cables.

 

check if there is water in the fuel? has been outside for a while, and check if there is not an animal camped out in the exhaust?it may be blocked.

 

I had a Throttle position sensor fail on one of my Triples, it caused assorts of problems, but I am sure it put the MIL light on.
