During operation, these rings help seal the combustion chamber, improve heat transfer and even regulate engine oil consumption. So, whether your existing rings are damaged or you are looking to rebuild your engine, the 2-Stroke 48cc Piston Ring Set has you covered.

The wrong rings!!!

I ordered the wrong rings from them but they got here in a timely manner. The reason they were wrong was my fault and the people I have spoken with on the phone are very helpful. I will continue to order here.

With proper break-in they work great Heads up, long review.Interesting story that I hope helps somebody.I did not properly break in my 48cc 2-stroke engine when I first got it.This is my first build and I got the engine off eBay with an incomplete manual.My understanding was the break-in fuel-oil mixture did the trick.IMPORTANT: after installation you must run heat cycles to help the rings make their initial seal against the cylinder wall (as well as use a 16:1 fuel-oil mix).There are a number of methods to this madness so look up ""2-stroke engine break-in heat cycles"" and you'll find a number of ways to make it happen.I did not do this when I broke in my engine so the rings that came with the engine didn't seal properly.After 2.5 gallons of fuel, one of the rings dug a nice groove in the cylinder wall and I had to replace the cylinder and the rings.I bought a new cylinder and rings from Bikeberry and they arrived without a scratch and went together with the least amount of trouble you can expect when reassembling a 2-stroke.Also, I've found WD-40 works better than assembly lube (like royal purple) when sliding the piston back into the cylinder and if you can, use para-synthetic oil or non-synthetic oil when breaking in your engine in any case.The synthetic oil is so good at creating a slippery surface it keeps the rings from sealing properly while breaking in.Funny enough, I also used synthetic oil when I broke in the first time which probably helped toast my engine.This information is a combination of experience and research on the many forums that exist online with a huge number of threads related to small 2 and 4 stroke engine installation and maintenance.
