Engine mount chain tensioner and hardware may be a bit rough, scratched, scarred or blemished otherwise, but it will function perfectly fine. It will make the left side of your engine stick out a bit further so please make sure you have at least 1/2” clearance between your left pedal and engine before you purchase. (We’re sorry, but the free chain tensioner is nonrefundable, nonreturnable and no trades.) If the tensioner makes your engine too wide for your bike. Solve the issue by: 1) buy a wide crankset -or- 2) file down your left crank and/or tension and bolts to clear.
Some parts and/or hardware may vary slightly from that pictured, but you will receive everything shown and described herein. Some scrapes and scratches are common in parts and paint so please understand that.
*** These engines are not ported, but they are among the most powerful stock motors available.
