I got a kazuma 150 a few months ago but no manual and i cant remember what oil is best to put in i think it was 20/50 but im not sure can anyone help me !!
ive also removed the exhaust tip and insides will this do more harm than good ?

 

I use Valvoline 10-30 in my wifes Yamoto 150.

 

My kids Kazuma Falcon MKII 110cc calls for 20W-50 oil.

 

my manual for the falcon 150 mkII says 20w/50
could you do me a favor and look on your engine and see what size it says mine says 124cm3 and it is supposed to be a 149cm3

 

Steve, as stated above, the manual does call for 20w50 but up here in the northeast I typically run a 15w40 during the summer and a 10w30 or 10w40 in the winter. Oil is cheap and a few oil changes a year will make the motor last that much longer. Good luck

 

my quad also has 124cm3 stamped on it and its a 150cc as far as i know ??
thanx to you all for the help STEVIE
