What brands/model#s of oil filter fit a Buddy 125?
What spark plug brand/model#s fit a Buddy 125?
And related ... I did find some discussions of what oils to use, apart from buying the high end synthetic Motul oil, are there any recommendations? Does it need to specifically say it's 4-stroke oil?
For the oil filter, I did see one post mention HiFlo Oil Filter HF183. However the couple sites I found those for sale on did not mention the Buddy125 as a "compatible" scooter. I also saw a site advertise a Malossi Red Chili filter (M0313382) as being fora Buddy125 but it was a performance part and close to $20. I just need an OEM type part - unless someone can convince me otherwise.

For the spark plugs, I found one mentioned; NGK CR7HSA. Are there any others recommended? How about an iridium plug?
Thanks in advance!
