Hello, So my Kymco has already broken the 2nd piston of course I was so stupid and didn’t change the cylinder So now I know of course not what it is that the pistons are broken Is there any way to check if the crankshaft is okay? Without going into a workshop and without special tools? The crankshaft is here removed and I assumed that the hood is because the left and right game has net a lot but but what was on the Internet that was normal game but net the KW itself but the part where the piston comes to it Up and down there is nothing Could that be due to the Kw anyway? Or can I assume that the cylinder is to blame? I want to change the cylinder now for 70€ and then find it was due to the crankshaft then I can buy the cylinder + a new crankshaft that I can really not afford Ach and a mistake at the time build I made net And the scooter also drives net too thin And the new piston was already broken after about 10km On the piston are so deep scratches / notches While those are only front and back at the side hardly With front I mean direction outlet And my oil pump is still running
