National Engine

Not a bad deal if you get it for cheap. Kind of would like to see some pics of the porting though. I didn't know they swapped in a WR200 piston. Nice to have the Barnett clutch as well and the 36mm carb. Not a bad deal really if you need a bolt and go engine and are lacking one.
 
Edit: nevermind, I wonder what's wrong that he is selling. I'd be wary but that trenga LRD right side pipe he has looks nice
 
WR200 pistons run in .8mm increments instead of the even numbered ones blaster's use.

Instead of 195cm³ in stock format, the properly sized WR200 piston is used to get nearly EXACTLY 200CC's (199.8 CM³ as stated) per class rules.

If you've got the money and time, and winning is paramount you'll do what's needed to squeeze those extra few cc's out of it...

So what happens when you need a new top end?......you have to get it resleeved?
