What did you do for the motor/swingarm pivot cut anything? and what front sprocket are you using?Thanks

[@justinbrito5020]

How hard was it to make mounts was it far off from factory yfz mounting points? And also how’s the motor feel in there being a dirtbike engine

[@nicholascaudill6185]

What air box are you running? If you ran the yfz stock air box, did it fit the carb easy? I've got a 325 esr kit on my 2001 yz250 motor and it's sitting on an 06 yfz frame. Ive got an esr trx 5 pipe on it as well from a trx250r. I'm running a 38mm pwk short body carb with pump gas dome in the head with esr reeds.

It's hard to describe how I did it but I did use the stock air box if you have Instagram I can send you some pictures

How well does or did the transmission hold up?

[@va6341]

I swapped the original transmission with the yz250x transmission seems to hold up well

[@onewisedre]

@@va6341 thanks for the response.

[@Cmiller741]

Does this vibrate bad since there’s no counter balancer

[@va6341]

It does have a little vibration but nothing crazy it's still rideable and a lot of fun

[@eliasdimitropoulos7801]

How is the power compared to original 450 engine?

[@va6341]

It's a different kind of power a lot quicker through the woods way more fun than the 450
