Howdy, my name is Patrick

I bought my first bike, a 2013 Yamaha Stryker, when I was 42. 9 months and 10,0000 later I traded it for a new 2014 Super Ten ES. It now has 52,000-ish miles with about 5k of those miles from Jeep trails in eastern TN. The bike is starting to act up so I am joining this forum to get some direction for possible fixes. She does a lot of chugging below 4,000 rpm and is pretty un-ride-able below 3,200. The stator and regulator both checked good. I've put new plugs and coils on with no change. I was about to install new injectors when I started reading this forum. Now I'm leaning to throttle position sensor issues.

Welcome! Assuming valve checks have been performed at specified intervals (every 26K)? Take a look at the rubber vacuum plug on the right side throttle body sync port, they tend to get brittle and crack. While you're at it, sync those TB's.

That's all I got, the smart guys in the room will be along soon........

UPDATE: Thank you everyone for the welcomes...
I found the solution here in the forum. Thank you Tremor38. The Jumpy throttle Fixed thread is great. He included clear instructions and pictures. After spending hundreds of dollars chasing issues and having a Yamaha service shop check it out, I just worked the throttle linkage at the throttle bodies while cleaning everything with carb cleaner. It seems like there was an issue with the throttle position sensors. I've put about 200 miles on the bike after this and the problem has stayed away.
