Throttle body gunk, intake trumpet and TXC ECU / Injector upgrade (2011 TE310)

[DRCA]

I finally got around to install the TXC ECU / Injector upgrade on my 2011 TE310. I just been able to run it up and down the street for now, but it feels a lot snappier and cleaner running. We'll see when I hit the trails this week-end.

Quick question on this: do I need to reset the TPS, or do anything else? What are the recommended CO settings?

Now, when I took things apart, I was shocked how dirty the throttle body was (note that this bike has 1000 miles only):



And that's the engine side (the airbox side was as bad). It took a fair amount of effort to clean up too (gasoline and a tooth brush). Any idea where this might have come from?

Also, in another thread someone mentions the existence of a "red magic trumpet" in the airbox like this:

I don't have it on my bike. So, how much of a difference does it make and where is it available?

Happy trails.

holy shit- what is that stuff?? it doesn't look like dirt to me; is there enough reversion in an '11 to cause that? I suppose you've heard of the 12 hole injector mod (over the stock 4 hole injector)... but I'm not sure it would help.

I'd figure out what that "stuff" is first. Make sure it's not dust & oil.

I think the velocity stack is a red-head factory addition (that's my bike in your picture). I doubt you'd notice any huge power increase (and on TE's it was restricted to decrease airflow- once modified to be an open velocity stack it did help).

Wasn't the injector upgrade a Kawasaki injector?

That junk looks like it could be from an over oiled air filter? Then some dirt stuck to it.

My 2010 TE250 has the same stuff allover the intake.

I think it is oil blow by from the Crankcase ventilation system.
The oil is sucked into the airbox past the filter.

Blow-by makes good sense.
