Can anyone tell me the proper fuel/oil mix? I run bel ray HR1 at 40:1 in my 03 cr250 can I use it in the quad? Does this quad use a B8 or B9 plug? Thanks again.

 

The factory premix ratio is 20:1. Yeah you can run the 40:1, but you have to jet it correctly. A lot of guys run 32:1. I run 40:1 in my '86 QRacer. You're supposed to run a B8 normally and a B9 if its running on the warm side.\
Hope this helps
later
