New 300 S3 cylinder and head... nice!

Wow, vast improvement over stock! The entire power spread is much better top and bottom... can't wait for a first 30 mile ride! Not a cheap proposition and dealing with the importers is horrible! I'm amazed that a business can stay in existence running such a poor business etiquette, but... its the only game in town!

I bought mine on Ebay with no issues from user n.tahoemotorsports. Definitely not cheap though.

YES, not cheap! I bought from my dealer(SMS in Denton Texas) he processed everything ok... It was the importer that was not very good! They sent a 250 top end in addition to taking forever... Not very attentive.

On a great note... I have ridden bikes with their head, much improvement but when you combine both head and cylinder the mid to top is Very strong. The bike was rejetted and is still running to Rich on the bottom. The bike currently is set up as a 250 so it needs gearing changed(down to a 48/50 tooth rear vs 52) and the way I ride dictates a gnarly pipe as I don't care to ride that hard anymore (did I say lazy/older!!). The stock pipe is more of a mid pipe which would be good for open/cross country riding.
... More to come!

Risk74, are you running the full topend? Elevation? What type of riding do you do? Just curious on any thoughts...
