gummed up injectors

I was going to say it might be bad fuel. Not all gas stations sell a ton of premium gas so if you got gas at a non busy station could be old fuel.

Many times its just the belt, it seems once they hit 500-700 hard mountain miles, they will show about 200+ rpm drop, a fresh belt and rpm is back. Maybe they get softer with repeated heat cycles...??

Make sure the belt height in the secondary pulley is adjusted properly. This can gain you some lost rpm as well.

The gas ran fine in the 2015 T4 that I rode with, we are carefull about gas station and age of gas. reed valves good, one tip was chipped they were covered in a light oil film, replaced with V force. Pulled rave valves they were a little covered in oily residue cleaned them. Going to take it in and have it scanned by Doo tomorrow. I keep the belt deflection tight, don't take chances with Doo clutches after 2007 clutch nightmare. Only 850 km on my sled.

Fuel filter? Etecs have very fine/small micron size....0.5 I think. ..had a similar issue on 13 summit..change it every season now ..$20

Thanks for all the ides fellas, I was thinking if this was an injector, bad fuel, TPS ect would it not flash a code? I don't think it was a fuel quality issue as I had 3 tanks from 3 different stations and ran the same.

If it was bad fuel it may just go into a different fuel map to save the motor which would make it run poorer.

So it turns out the primary spring is weak, it does not show any sag(same height as the new one). it does not show untill you compress it to 41mm. less than 900 km's on it.

you did the secondary too i hope. if the primary was sagged the secondary will be for sure too. and its only $35.
