Yeah i like that better than my neon yellow 22

I have a 22 . They pop and crackle all stock for sure. No tune will make tje header stop glowing if you go down that rabbit hole and the clutch is good long as your not tractor pulling with it or have it turned up 20 hp. Just ride it

First thing you do is replace the clutch basket or you can just throw your quad in the trash. If it fails it will destroy your bottom end. Also the vortex ECU improved the performance significantly.

Do those fail commonly on these YFZ's?

Vortex is the best ecu for it

I’ve had a 2009 yfz R & 2013. The best efi controller for these quads is a MSD blaster FI or vortex efi controller. I’ve already had PCV & other controllers in the past. If you want it to run the way it should get yourself a legit efi controller. Sell that PCV…

i had a msd and that was the biggest waste of money glad i got a vortex

I just bought a 2019 yfz450r and i think that things taken out in my Exhaust too and it backfires on Deceleration.Did yours backfire on Deceleration before? And if so did thatt fix it, and why did you choose that over the Vortex?

Is it really a used quad if it doesn't have the baffle removed (and stock jetting/tune) by the previous owner?
