My 2015 YZ250F has some issue. Runs good and starts good, timing on point and valve clearances are great. It just bogs bad and cuts in and out from gate and out of corners with the occasional pop. Anybody know what is wrong?

Tons of threads on here if you do a search. 1st place to look is TPS and all electrical connections.

I had to replace fuel pump in my 15. That was 500$ then 2 rides later the connecting rod broke.

TPS, trust me. If it hasn't been updated to the 16 up part number order one NOW! I am the one with the big thread about it, spent THOUSANDS chasing the problem....

Dirty injector? Dirty fuel filter?
This ^^^. Dirty injector. Had the same problem on a 13 Yz450. Doesn’t take much to clog them. Get it cleaned and get a Twin Air Filter that goes inside the gas tank.

Dang! That is some bad luck!
Yes . I guess I was due. I have had 8 yzfs going back to 03. All were very reliable.
