some guys need to put this in perspective, you guys are acting like youve spent $400 for these engines.They are$200 people, what happened to the days that for $200 the most power you could get was an os RG.

IMO dont waste time on the perfect breakin just heat cycle it a few times and hammerdown, if it blows at least youll be running it full wood not waiting two gallons for metal pinch to pass.

that being said ive been hammering on mine and have no complaints other than the lsn is a little sensitive, frankly it tunes better and runs just as hard as my jpx.21s
