number6 7 Posted September 29, 2013 Can anyone advise me if I can tell if I have a Jawa short stroke or Long stroke? are there any markings ect to tell? Share this post Link to post Share on other sites
Long Eye 278 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. Share this post Link to post Share on other sites

XTC38L 79 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 Share this post Link to post Share on other sites
