Its on top right side of the coolant tank under the steering shock.

a picture would help. but that would be the coolant pressure sensor, that is if you are refering to the sensor on the coolant tank.

Air pressure sensor is what I believe it to be.

Yup that's the one. Air pressure sensor. Would that cause the bike to run like ass?

 

[Aussie_Bob]

Shouldn't do imo.

It basically just provides minor adjustments to fuel based or air pressure - a quasi elevation correction of sorts.

Yes. It most certainly can. I chased an intermittent running fault for months before I lucked onto that sensor.
The bike would suddenly run rich and surge for varying periods of time and at different temps. The connector was corroded. Cleaned it, immediate fix.

That's about the same problem I have . One day it'll run like a champ but then when I try to with with a group then it backfires.. Surges.. Won't idle.

 

[Red Enough]

How did you go? Was this the problem?

 

[speedn.j]

We'll it wasn't the sensor per say.. But the connector was very corroded. Cleaned it up and the bike ran like a champ. ( I hope that was my problem)
