These motors RIP hard! I have been running one of these both in my ski and Tem's superfreak loaner for several months and am stoked with their performance. Blue has been refining the sleeve and porting design on this motor for over a year now and it is right on the money.

The wording sounds like its its an up charge so figured I'll ask anyways. Does the short block price of $2680 include a ADA head & required domes?

Chris, how much is a complete motor with the ADA head, intake and carbs, no core and does it come as a RTR drop in or do I need more ie. flywheel etc.
Cheers Ray
