Cougar SV change inner gears?

[atLihOp]

Hi,
I run my cougar with the standard inner gears.. and with pinion 25 and spur 80.
I drive with a Nosram pure evolution 7,5turns.

But my motor is always getting too hot...
What do i have to change ?

thx

could be geared too high. from the sounds of a 8.26 FDR that's probably it... try a 23 pinion and see how that goes.

what sort of track is that on? indoor/outdoor?

I ran 8.45 FDR in the cat on sunday at kiddy without any temp problems, but it was really cold outside

Ok I will try this..
It is an indoor track.

grtz

Your gearing is way too high. I run a 7.5 also at a indoor track. 20 pinion and 82 spur....its a bullet and the temps never get above 130-140

at chaleroi on the same track, 7.5 in my cougar was on 24/80 and was getting very warm. id recomend a 23/80 as a starting point for there next time
