Very Happy with purchase.
Great product, great value, would highly recommend to other people needing to replace their cylinder. You should also rebuild bottom end of your cylinder is with enough to replace it.

vertex pistons
I ordered two cylinder kits with pistons made by cynlinder works for my 750 teryx. The cylinders are great looking no visible flaws. The vertex pistons that came with the kit are of poor quality. One piston came with a broken ring set. One piston would not fit the wrist pin in it because of machining and had to hone it to make it work. The clips that hold the wrist pin in are cheap and almost impossible to install without bending them. I believe cylinder works makes a good cynlinder butI am sorry I ordered these pistons at the quality they seem to have.

Beware. These are Junk 2015 KXF450
I purchased (275) the standard bore high compression kit. I installed it and at start up I could heard a loud knock for every revolution the motor made. I pulled the valve cover and double checked the cams and valve clearances. Everything looked great. Fired it back up and it still had the knock. I had no choice but to tear it down and reinstalled the stock piston and the knock was now a normal low four stroke knock. I contacted RM and was informed since I installed the parts I would have to deal directly with cylinder works. Jim Burt had me ship the parts to him and a couple weeks later his engineer measured them and were not able to find the issue. He stated there kits are just louder than a stock top end. Funny because the box it came in states quieter. He shipped back the original parts and told me to deal with RM. RM will not refund or give a store credit on any part that has been installed or is used. I have installed numerous top ends in 2 stroke and 4 strokes and never heard such a loud knock in a top end before. The kit I bought standard bore high compression isn't even available anymore. Weird. Do not buy these kits. Go with the OEM and save yourself the headache and your pocketbook.

One happy customer
I can not tell you at this time how the Teryx works but at this point everything fits perfect. I could not believe the speed in shipping as I am in Canada. Fastest I have seen yet and I order alot from the US.

Overall good product, easy installation.
Good product, but hardly any instructions or guidance for a first-timer. The video on Rocky Mountain's website is really good, though. It all fit well except the line-up pins provided were not the correct pins. I had to use the pins out of the previous engine.

These cylinder kits are a life saver, especially when in a pinch before race weekend!
These cylinder kits are a life saver, especially when in a pinch before race weekend! We've installed dozens of these cylinders at our shop and never had an issue. Ring end gaps are generally pretty close and the cylinder plating quality is amazing. Can't go wrong with price either.
