Timing chain -PIAGGIO 2+3- HiPer4 50-100ccm AC – 84 links.

Timing chain in the usual good OEM quality.

Both the timing chain and the timing chain tensioners should be checked every 10,000km. Sloppiness can have expensive consequences here, because lifting the timing chain from one of the sprockets leads to a skipping of the chain. In the best case the engine simply stops, in the worst case the valves collide with the piston and a capital engine damage occurs.

An easy to carry out check in the given interval looks like that the spring for the timing chain tensioner and then the chain tensioner itself is removed. When the tensioner pin is pulled out, a clicking sound is heard. If it clicks 4-6 times, everything is okay. If it only clicks 2-3 times, there is a noticeable wear and the chain should be replaced.
