[808ministroke]

So upon examining my engine the other day I noticed a crack where the CVT part meets the crank case I thought it was not as far as it was upon examination today it's parent that it's percent of the way through the entire case it's still held together below are pictures of the crack with the kicker covered on and without the kicker cover where the crack is a little bit wider Any suggestions please let me know I have JB welde I have a welding friend I heard aluminum can't really be welded too easy I love this engine and I want to save it by all means necessary

Is that the Piaggio lump? I have seen a few Piaggio cases break there.
It could be welded, but that is a high stress area. I would personally replace that case half.

dang so this is a common occurrence, I feel a torsion arm would have prevented this .
I am not ready to throw in the Towel this block has been though hell with me me buddy said try alumaloy to weld it with using a map gas torch.
