Long Eye Posted September 29, 2013 Report Share Posted September 29, 2013 Have a look on the left side of the crankcases just below the barrel. Assuming you have a laydown type it should be marked with 884 or 889. The 884 is the longstroke model with a bore and stroke stamped on as 85x87 and the 889 is the shortstroke with a bore and stroke of 90x77.6.

XTC38L Posted October 4, 2013 Report Share Posted October 4, 2013 888 is the first of the short strokes. 88mm bore with 81.2mm stroke. Setup properly they are quite a good engine Quote Link to comment Share on other sites More sharing options...
