My bike is running a bit rough, losses power under load. If i hold the throttle in the right spot for the rpm it will sound ok, also seems to idle fine.
Compression is 190-210, spark looked strong with new plugs, fuel pressure is good at all rpms (3.0 Bar), injectors have a good spray, clean air filter, no FI light. The C- is good but will rise up very shortly when i rev it, ive removed the secondary throttle plates, i also ran the bike with no atmospheric pressure sensor for a while and just plugged it in.

The - should go to the top as soon as the throttle is opened.

Why did you remove the secondary throttle plates?

Are all the hoses connected to the air box properly?

Was it a hot day when you noticed the power drop? Could it be poor quality fuel?

Could you describe what it feels like/what the bike does when you lose power?

Sorry for all the questions.

I routed the two breather hoses to atmosphere and pluged the airbox nipples. everything else is there

I removed the plates to make sure there wasnt an issue of bad actuator

The bike doesnt run worse or better at any temp

It feels like it is hesitating, like its losing a cylinder or getting bad ignition timing. It will alternate between running ok and then dropping power randomly/depending on opening of the throttle, mostly runs bad though. Im thinking maybe tps?
