Your video shows the left side TB butterfly's OPEN MORE than the right side ones @ WOT.

There is an adjustment screw in-between the main two throttle bodies.

*Someone was definitly in there dinking about and screwed that up big time**.


Part #10 is your TPS: https://www.partzilla.com/catalog/yamaha/motorcycle/2005/fz6-fz6st/intake-2

It's connected to the RIGHT SIDE TB SHAFT (which ISN'T OPENING fully), thus giving the LOW, 63 reading (should be about 100).


You really need a synchronizing tool to set the TWO TB's back in sync (PHYSICALLY, NOT just the air screws). The TPS reading will then go up as that center synchronizing screw gets them close to each other..



I circled the adjuster in blue that sync's the TB's together:

If I remember correctly you should see 16 - 100 reading on the tps. I hear a click when opening and closing the throttle bodies. The throttle bodies may be fine but the tps may be bad. That bike doesn't have a physical throttle limiter does it?

The throttle is opening way TOO far (left side at least) to have a limiter, but here's a pic
of one which attaches to the left side for the cables:





I do agree thou, that TPS won't likely change another 40% or so .

i cant believe it !!!
just take a look at the bike it has the limited throttle !!!!
in the vehicle license its 98hp with all correct chassis and engine number.
what a weird bike i have
its 2007 model s1 but with o2 sensor and same as s2 header no abs

i bent it did the d1 thing
close 16 open now 101

Excellent!

I would still have that throttle body MAIN SHAFT ADJUSTED so all butterflys open the same.

Did your flashing light stop?

JM2C but the camera angle appears to be introducing parallax thus making it look worse than it is.

Don't mess with the screw just yet. Look for paint up and down the head, spring, and base material. If in line it likely hasn't been changed.

Placing a vacuum gauge to the sync tubes will tell you a lot. The right side would be very low compared to the left.

I wish I could find something like that on my car and get 25% more power! Blah

These are the sync tubes.

well
its all open at same i guess its the lighting flash and camera angles looks otherwise .

i did a ride now
all i can say is WOW :rockon: and i thought i had 98 hp haha ill go to the dealer to ask how come they selling 98hp bike with a limiter
the fuel guage keep flashing but the bike feels as usual so i dont know

Again Thak you peaple
