Big john and i do ride hard at times, we hit 120 very easy and often in 4th, heck 4 of us rode here fron central pa to sturgis in 2 days, when going with higher comp, its called cool that oil down!!!!! minimun 10 row jag no thermostat, fans on cooler optional, the location of cooler should be on the down tube out in the air flow, and of course lower afr's too and in summer i always run straight 50 or 60 wt use oil filter adapters for the oil coolers with no thermostats ,flow more ,no stat to impede it, just make a cover in the cold weather. , a jagg rep told me that, also bob woods to. had 11.1 comp in my 116 .
still hate the 255 cam, said that for the thread sake
