you for replying i hear there is a way to flush the crankcase would you know anything about that? where is the needle bearing located?Looks like the needle bearing in your piston came apart which caused the damage.
If you have pieces of metal left in the case it will happen again
That is a high wrist pin hole piston which are $10
You are all over the place. lol
any idea what size replacement needles would be needed ?Remove one of the clips on the side of the piston to slide the wrist pin out to remove the needle bearing.
Your piston, cylinder, needle bearing, clips, wrist pin are all trash.
Might be easier and better to buy a replacement motor than replace the top end.
A magnet on an extendable rod may find any needles in the case as they are steel.
Then wash case out with gas and oil mix.
We are having a race in Perris on Sat Oct 27th which is only 80 mile north of you.
