Engine running hot
Anyone ever had their evo overheat. After riding mine about 30 min @ freeway speeds, it starts cutting out. Oil temp is showing about 220. I can let it sit for about 30 min. And starts just fine - until it get hot again. Any ideas?

If not or if you have a CRANE HI-4 heres a trick for ya. take a hairdryer and with the ignition cvr off start the bike and blow the hairdryer on the ignition. when it gets hot if it starts to cut out then you found your problem

In addition to the above, check the ignition timing, and if it's jetted too lean, that'll cause it to overheat for sure.
It shouldn't overheat to the point of cutting out at interstate speeds. Is this something that just started happening?

I've checked the ignition. I've been running a compu fire ign for several years using a factory module. I did the hair dryer trick early on & have since replaced it.
It has historically never run hotter than 200. That's in slow traffic & Texas summers. When if cuts out, the cam cover is WAY hot. Oil temp at that point is at 220'ish. Once it cools to 200 or below, starts right back up.

I just replaced the cam, inner bearing, & pinion gear while troubleshooting the hot cam cover issue. I figured that was it.
Once I got it all back together, it started the overheating thing again. Oil pressure is normal. I'm stumped!!
