Ray A Racing Piston and Sleeve Resizing Service


Last year, I’ve lost my air filter on my Reedy 121VR engine. As expected, dirt has entered the carb, my engine ran really lean and I ruined my piston and sleeve. My piston and sleeve were so much ruined that it was easy to turn the crankshaft even with a glow plug installed.

When I got back home, I disassembled the engine for a complete inspection. Luckily, there was no dirt in the crankcase and the bearings were spinning smoothly. However, the compression was gone and there were few minor scratches on the piston. I had no difficulty to push the piston all the way through the top of the sleeve. Then I’ve put all the parts in a bag and I’ve placed the engine on the shelve.

Six month later, I’ve heard about RayARacing.com, a company located in New-York and specialized in piston and sleeve resizing.  After few searches on the web, all I was reading about RayARacing was good comments so I decided to try their services. I filled the order form located on their website, sent the money with Paypal and sent my piston and sleeve.

Less than two weeks after, I’ve received my piston and sleeve. I live in Canada, so shipping takes a little more time than if I was living in USA. The turnaround is 1-2 days so you can expect to receive your resized piston and sleeve quickly.

My piston and sleeve were looking like new. The first test I did was to push the piston into the sleeve just to see where it will stop. The piston stopped at about 6-7mm from the top of the sleeve, that’s excellent. You can select the tightness you wish, in my case, I selected medium tightness.

Once my engine was rebuilt, I did a little break in, just to make sure everything was fine. The engine fired up instantly and I broke my engine in by using a heat cycling method. Once I have set the engine to its optimal performance I’ve ran the engine for 5-6 tanks consecutively. Back to the pit area, I’ve turned the flywheel with my thumb to inspect compression and there was a lot of compression. In fact, the compression was exactly where it was before I ruined my engine.
