I was wondering what ratio's you guys are mixing your oil and gas for your RM 250's. My buddy told me 31:1 is that anygood? also what plug should i be using a BR9es?
Yeah, don't go less than 40:1... (41:1+)... keep it in the 30's and you'll be fine. Won't hurt to go a little extra. Anything more than 25:1 will end up smoking and clogging your pipe up really quickly... probably foul a few plugs in the process too.
I've used AmsOil HP injection 2-stroke oil and I've never had a problem. Really nicely produced oil. Plus, it's cheaper than Motul or Yamalube...
