09 Beta 125 Overheating

Postby Stanm » Thu Sep 15, 2011 5:48 pm

Hi Folks
My sons Beta 125 overheated and the hoses bulged and blown head gasket. Found the impellor fell off the water pump. Not sure if this is a common problem but it is easy to check. Those with 09 125 should drain the coolant and take out 3 screws on the water pump cover and check the longnitudal slop in the shaft. The pin will drop out and cause damage if the slop is to much. I installed a 1.5mm spacer on the shaft to stop it happening again ( gear side) Good thing the side cover and water pump gaskets and reusable.
Hope this helps others and let me know if you need more info.

regards

Stan
