Default B-max still running hot.

My cp B-max is still running hot. Specs are -

Nosram matrix evo istc (auto set-up at the moment)
Novak 5.5t
spur 87t
pinion 19t
GM 4200 lipo 30c
Tested with Schumacher yellow mini spikes on short grass and astro track

Just had a fresh rebuild, smooth diffs, nothing binding. I was thinking of changing out the spur to 81t and using another pinion. The car still seems slow on the straight, but heat keeps building. Need some ideas.
