Jammin release new Pro .21 & .28 Engines
Jammin have announced the release of 2 new pro engines, a .21 and a .28 motor. Both engines have been optimised for off road racing and both feature turbo plugs as well as a number of other performance enhancing improvements.
Tweaks to the materials, crank timing, and tolerances all played a part in getting the engine to the high performance edge that Jammin Jay requires. Both engines deliver excellent bottom end power with great top end run out.
