Hi,
Thanks for youre help again axy. To be honest im not sure if it is bearings OR crankshaft because we didnt continue stripping it any further but it is one or the other. I am very confident in my freind and the starter motor worked ok on its own but jammed when it was atatched properly due to the crank / bearing problem. Also the kickstarter didnt work correctly it also got stuck. I will take some pictures of the stage im at as I am sure I should be able to describe the problem better so you can identify it is a serious problem. I shall do it tomorrow.
Thanks again.
Pls do.
Btw. regardless of you changing the oil by yourself, I think you should try to claim the warranty.
If it is really crankshaft or bearings, it is a manufacturing defect and warranty should be valid.
Try to find a good dealer willing to go down that route.
These engine parts are quite expensive, I will say this without checking but crankshaft itself is easily 400 US$ + a number of bearings and small parts that have to be replaced (pins, bushings, gaskets, etc.)
