Need some good advice from you
after 25 000 km my Scorpion tour engine made some clanging/tapping noise.
To begin with my motor has Solid balance shaft gears (without springs). The motor is open and it has NO loose nuts/woodruff keys.\
What i noticed is a snapped Cam Chain guide and scouring on rocker arnm where the Decompression pin hits it "momentarily"
First picture is the snapped Cam chain, I measured it and got 25.3 cms, does anyone has a new/used and measure it for me so I could determine how much it s shortened and if it was the cause ?
Could it be the cause after all ?
Could it be that the auto decompression pin is not retracting back, i noticed scouring marks , picture below.
Is this normal I ride the bike almost every day so I start the MZ twice daily every day(deco only works on startup hence an idea of usage)
Looking forward for replies so ill order parts and start reassembly of the engine and bike(I just prefer it than the heavier B12)
