Gas Gas Recomendations

Spark Plug NGKBP5RES, Champion RN11YC, Bosch Platinum WR9DP

Trans/Clutch Oil Always 5W30 (Not 10W40), 350cc for the Pro, 650cc for other models, normal motor oil (Castrol/Penzoil etc). It is not recommended to use synthetic oil.

Gasoline 95 Octane minimum. No alcohol type blends. (Jim uses Sunoco purple 115 octane 20% to Shell unleaded premium 80%).

Premix Between 80:1 and 100:1

Brake Fluid DOT 4 is standard. DOT 5 is fine. (All higher numbers mix with lower numbers).
