13:1 what gas?

[mxpimp2000]

ive been running striaght 110 pump gas in my yfz it has a 13:1 wiseco piston and its expensive i was wondering if i could still get same performance if i run 105 or 106 or 107 because mixing 110 with 93 i can lower my octane rating

i use this octane calculator:

Most go 50/50. If you do that you're good. I think it'll be like 101 or 102 octane or somewhere in that range.

If you mix it 50/50 it should be good. I run VP that is 114 and I mix it with 93. If you take the 2 and add them and then divided by 2 that will give you your octane reading.

For example 114+93=207
207 Divided by 2 = 103.5

So Your octane reading would be 103.5

When you mix your gas you do not end up in the middle it will be lower there is a lot of bs in 93 it is only another 5 dollars when you ride ride it strait at 13.1
