It was machined perfectly and fit like the OEM cylinder. No problem at all and it has about 50 hours on it now.

Better than oe, goes back to the original one that yamaha used that didn't break off so easy.

I bought the big bore kit for the WR250F. The whole kit fit very well, and it gave nice low end power to my bike. The gasket fits great with no leaking and has been solid for the past 5 months of riding. I also bought an extra gasket in case I need to do any major engine work. It's always a good idea to keep a set of engine gaskets ready.

Runs awesome in my crf250x! Seems very high quality. It was a pretty simple plug and play install.

Great upgrade for my 2014 FE350. Noticeable power increase. Great fitment to the stock lower.
