All you need is a pinion gear a couple of teeth smaller. That will reduce speed and give you more torque and you’ll run cooler.So I bought two older style ruckus’ old batteries were junk, so automatically upgraded to 2s lipo.. well... after running it through some trail terrain (working on making it like a track... not there yet!!) I smelled the smell!! Grabbed it in the back side and oh yea bit warm..... not quite as hot as my old ladies .. but the smell... I’ve heard of this smell... It is not as elusive as I had thought. So.... now what! Go brushless.. .. ? I want power.. to pull it off a stick on the trail or something.. no need for speed... they are for my kids... I’d like to tone it down on speed if anything..
