The bearings are cheap low quality bearings compared to Nova bearings as well.

For me it's about reliability and knowing that my engine is going to run strong and consistent thru an entire race weekend without chasing a tune or an air leak. Not saying that the K9 is bad, just saying that I personally have never had an enjoyable experience with an engine that came out of Taiwan. I could be wrong but I doubt your gona find a engine from Taiwan that has 12-15 gallons on it with no more than a rod replacement. Maybe I am missing out on something special because I don't want to take the chance but I just like to stick with what I know works week in and week out.
