Ive got a couple of these motors from Ryan and also modded alot of these for customers. They are all VERY pleased with them! The 30 is deffinatly a good bang for the buck. The engine is very strong and isnt as bad on fuel as youd think, specially for a 30. They come with too many shims factory, but thats an easy thing to remove and gain even more power
Im very suprised the bang for the buck the STS mills are giving! And Ryan from racernine has the best customer service in the biz hands down from my experience
Keep up the great service Ryan!
