ok, here's MY deal.
Put on the K&N's. yes, all 5.
Moved rad overflow to under seat.
Put my new custom homemade exhaust on.
To loud so ordered and installed a baffle.
Had her Dynoed.
Up to this point all is good.
Lost the baffle out, engine light came on.
Called son to bring trailer.
took her to shop. they said and I quote,
"second throttle circuit threw a code".
On the invoice they said, and i again quote,
"2nd set of injectors failed to open for a split second".
Paid my money, bike rode like a champ on the way home.
Today, the engine light came back on and it started idling about 3000rpm, and ran like crap again.
I wiggled the 3 wires on the top of what I'm assuming is the TPS at the end of the fuel rail.
The idle dropped almost instantly back to 800.
Bike ran fine and engine light went back off.
It did this a couple of more times on the ride and each time I'd reach under my left leg and wiggle the wires and it'd straighten out.
A few questions now.
1) is this the TPS?
2) primary or secondary?
3) How hard is this to replace, just snip the wires and solder connectors back on and the one visible screw?
Thanks for the help guys.
