Steven Duffy

I would highly recommend them. Keeps you well informed. Superior machine work and excellent turn around time.

Chase Fullriede

I could not say enough good things about motomonk. I have a 2000 KX250 that locked up, causing a lot of damage to the cylinder and cylinder head. I sent them out to motomonk for refinishing, and with a quick turnaround at a very affordable rate, they sent back my refinished head and cylinder, which looked better than brand new. I highly recommend them for any of your engine needs.

Frank Padgett

Sent them an 01 kx250 cylinder and they were extremely thorough in the options offered for repair. Ended up getting a sleeve, work is fantastic and with a quick turnaround. Highly recommended and will be using again.
