Thumpstar Oil Change

Recommended Posts

How do you correctly change the oil on a 06 125 Thumpstar Pro?

One of the drain bolts shot off when I loosened it. It has a spring and a long tube with holes in it inside. What is this for and does it have to be installed any particular way?

Thats the timing chain tensioner spring. Put it back the way it came out, with tube first, then the spring and you should be OK.

Thanks for that and thanks for joining up just to answer aswell :moon: So I take it the gearbox and engine oil are together?

To change the oil do I drop both bolts underneath and replace, then refill from the ONE opening where the dipstick goes in?

Gearbox and engine oil are the same. Just drop the oil drain plug, the flat 19mm bolt if I remember correctly. The tensioner bolt is the bolt on an angle, 14mm I think. Fill thru the dipstick hole. Glad I could help.
