X bones runs at 250*
Slim runs at 200*
Both mild stage 1 complete exhaust free flow intake
xbones using V&H fp3 with a canned map
Slim on dyno jet canned map

same oil. Change them at the same intervals using AMSoil in all three holes
Xbones 15k mi... Slim 31k mi... Why the Xbones run hotter?
Meanwhile, the Slim burns more oil. No too bad. Bout a qt every 5k mi and gets dark
The xbones burns no oil and it stays clear through out the 5k mi interval.
Scratching my head ober this far too long with no reason why. Any ideas?
