Default 13.5 Epic Duo 2 Advice

Hi I have decided to give a Epic Duo 2 - 13.5 a try with my Speed Passion 2.1 Stock

Can anyone please advice on gearing and or speedo settings

How hot can a Duo safely run without fans?

Normally run on a 30m straight track with fairly flowing infield

Thanks in advance

Try this setting:

4: 8
9: 7
12: 9
13: 3
14: 0
15: 5

Geared at 7.2
Timing set to 5 degrees on the end bell (halfway between 0 and the first line/notch)

Its very smoooooth, but also VERY fast. Runs about 70-75 degrees C after 5 minutes

Make sure you temp it though, and if its running to hot for you, back off 4 to 7 and increse 14 to 3 and drop 12 to 6-7
