Circlip in coolant port

I'd probably pull the motor and stuff some rags in the crankcase so it doesn't fall in there and try turning it upside down and shake it out or even use an air nozzle to try and blow it out

Tiny magnet on a string?

Haha I am at Walmart as we speak buying magnets , I'll let ya know how I make out

Good luck. I hope it works!

Buy a telescoping magnet from an auto parts store

Got it! Used magnet strip and worked like a charm after a few tries

Damn havent seen that before. I think im gonna get some of those strips just in case. Good idea

Good deal! We did top end on my son's 125 last weekend and this exact scenario crossed my mind for some odd reason. I always stuff the opening to the crank case but I thought about the water ports. Glad it worked out for u.

This is what I used for anyone in future. $5 at walmart
