Looking for help with engine issue

[MikeMetzger]

Riding my 22’ Matryx 850 and noticed the last 2-3 rides a slight bog at the lower end when modulating the throttle in technical terrain. Seems to maybe be getting slightly worse the last ride out. Got pretty unrideable today. Tried swapping plugs, no help. Started throwing codes 4 - 51 - 1 then 10 - 51 -1 had to call it a day. Local dealer pulled the P codes. Any ideas? I do have a Munster Finger Throttle, but i dont think the TSS bypass would cause these codes ?‍

All of the codes on Digital Wrench are "inactive" with the exception of th EV actuator.

Did you do an E-VES relearn?

Sluggish off the bottom could be E-VES valves not opening correctly.

Could also be chipped/ damaged reeds-- reeds will NOT throw a code.

Thanks for the reply, he did not do a relearn, mentioned it would take a long time for some reason, I didn't fully understand, but sounded like it wasn't as easy as just pushing a button and letting it do its thing. Initially it was noticeable only on the bottom end, but this last time out it was pretty much all over the place. Made an edit from the ride and you can see/hear what its doing at the 3:55 mark

That sled is completely cutting out.

Dealer diagnosed it today. Bad TPS Sensor, which for some reason, on the 2022’s you cant buy, you have to purchase the entire throttle
body ?‍ Im curious what thats all about. But Im excited to get back put there and riding!!!

Covered under warranty hopefully?

The TPS sensor is definitely listed as a part number separate from the dangerous and garbage worthy throttle block assembly. Never know about the sensor part availability, but be sure to have them put an aftermarket block on for you while it's apart.

It should be covered under warranty. Everywhere Ive looked, the TPS Sensor is not sold separately for the 2022 ?‍ This is the first Ive heard that the throttlebodies are garbage. Whats wrong with them?

He said throttle block not throttle body. The throttle blocks are garbage but Mike fights for the rainbow warriors and runs a Munster Finger Throttle so its a non issue for him. Mike is talking about the throttle body and TPS that had nothing to do with the the throttle position safety switch which you are referring to with the throttle block. Guys seem to always get these 2 things confused.

It's goofy, but they're not wrong
