malossi mhr replica aerox


New Member
Hey. I have a yamaha aerox with mhr replica 70cc cylinder, 17.5mm dellorto carb, completely standard filterbox and yasuni R exhaust.
Which main jet size would be near perfect for this setup? Beafore I changed to the mhr replica cylinder I have the sports cylinder malossi sport 70cc combined with jet size 78 that I think was perfect.
Hope someone can help me with the new jet size. Best regards Jonas
