No. I mean if you're checking your belt or clutch weights, etc with engine not running. Do not turn it clockwise as you're looking at the clutch from the side. When viewed from the clutch side, the engine runs counter-clockwise obviously.
Reverse in this 4-stroke 998 is NOT like a 2-stroke - this engine does not stop and rotate backwards. Reverse is accomplished via the chain case and some gears and chains. The engine ALWAYS turns the same way.
No problem. The reason you never ever want to turn it backwards (clockwise when viewed from clutch side) is the cam chain can jump teeth on the exhaust sprocket causing the cam timing of the engine to get off. If that happens, the exhaust valves will be out of time with the intake valves and pistons. If it gets off by more than about 1 tooth the next a piston comes up to top dead center it will hit the valves and bend them. It's a MAJOR repair to fix. So, just be very careful to never do it. For example if you are putting a belt on or looking at your weights or primary clutch it's easy to not remember and accidentally do it. I think Cat should put a large ugly decal somewhere there close that everyone could see once they drop the side panel.
Have fun! These 998s are a hoot to ride, especially after getting a good tune. Once you pull the trigger on 280HP you're addicted for life!!
