I agree 110%. A Clocked JPX .21 is an impressive engine in every way. No other 21 I've see makes more power, and the mileage puts a smile on your face. I have a Clocked CRF .21, and a Clocked Sirio CL3B, both are excellent, but for less money, a Clocked JPX .21 will lay waist to a regular CRF ( or any .21 I've seen )
