I was out there saturday too, should have looked for you. Real nice day though.

 

I was over at the far west end, parked on the sand. I made several runs with the Banshees and one stock Raptor on the flats. I was pretty much the only Rappy making runs in the area. Some of those Banshees were awfully fast.

 

Heres something on the Raptor head When you get ready to torque it down you need to get some bolts that will reach down along the side of the camgear area . You know were the long skinnys go after you put the top on .
Any way you need to get some that you can tighten down ( SNUG ) as you pull your head down . Have actually torqued down a head and then added a couple of bolts to the side area and #2 and #4 have backed off . . And Yes the surface was flat . If you keep haveing head gasket failure try it
Heres a pic of the 2 bolt holes I'm talking about PIC

Also be careful pulling your thermostat it can cause you to over heat . Tstat is designed to let the radiator coolant cool off while the engine coolant heats up and then they exchange . if they work right it balances out . with out the Tstat the coolant just keeps heating and going thru the pump . You will need to keep moving pretty fast so the air will ram thru the radiator (RAM AIR ) when you ride slow it will over heat .
Hope things work out for ya
GOOD LUCK

 

Ya, I watched a couple races, I didn't want to get embarrassed too bad.

 

Has anyone used those aluminum in-line coolers? The ones you see on ebay for $25, I think Protech makes them. I don't have them, but I was wondering if they worked or if they were crap!

 

I know you just had the clutch cover off, is it possible you have air in the system somewhere???? That might be a wild stab, but before buying a new head gasket its a maybe.
