'04limited Posted October 12, 2008 Report Share Posted October 12, 2008 i'm putting my engine back together right now and i'm at the head i got a new chariot performance head got all the o-rings in place and i went to put the head onto the cylinders it wont sit down flush on the cylinders theres a gap between the cylinders and the head.. i also noticed that the domes do not sit completely flush into the head are they supposed to? this is my first time messing with an aftermarket head so any help will be greatly appreciated. thanks...also there were no instructions with the head so im not sure if i have all the o-rings in the right places.. but they all seem right. thanks again.

05.Banshee.SE Posted October 12, 2008 Report Share Posted October 12, 2008 I have a Pro Design one I have not put on yet, nor have I ever dealt with it... ...but I did see grooves in it for where the Orings go, and I believe you're supposed to grease them. I did a "mock" put together of my head, and it seemed pretty straight forward, and I believe everything was flush (at least the domes were flush w/ the head.)

jamebo Posted October 12, 2008 Report Share Posted October 12, 2008 I've never used the Chariot head, but I've installed a Noss head. If I remember right the domes did sit flush with the rest of the head on it. Like 05.Banshee.SE says put a little grease on your o-rings and make sure they are seated correctly. Maybe someone that is familiar with that type head can chime in. Quote Link to comment Share on other sites More sharing options...
'04limited Posted October 12, 2008 Author Report Share Posted October 12, 2008 well i put it on and torqued it down but the domes never did sit completely flush in the head but the head seems to seal up properly on the cylinders. Quote Link to comment Share on other sites More sharing options...
2strokecook Posted October 12, 2008 Report Share Posted October 12, 2008 i have a cool head that i just picked up and gonna put on the bike, i do believe everything needs to be pretty flush, i just ran down and looked at it and my dome might sit just a hair ( litteraly like a hair) above the rest of it, they are flush to the feel though. i didn't try pressing them in so i sure they will be when i clean it up and put it in. If they aren't i could deffantly see some potential leakage. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted October 13, 2008 Report Share Posted October 13, 2008 They are flush on my PD head. If the domes stick out farther that could cause a coolant leak twards the out sides of the cylinders. If they were to far in then the coolant could leak in to the cylinder and compression would leak in to the cooling system. Quote Link to comment Share on other sites More sharing options...
'04limited Posted October 13, 2008 Author Report Share Posted October 13, 2008 well like i said i put it on and it seemed to go on correctly but im still kinda worried but i guess i'll have to wait and see after i get it in the bike and fire it up? or is there another way to test and see if it will leak or not?

See if the local auto parts store has a cooling system pressure tester. You pretty much do the same thing as a leak down test only on the cooling system.

'04limited Posted October 13, 2008 Author Report Share Posted October 13, 2008 do you have to have a special adaptor for the neck on the radiator? Quote Link to comment Share on other sites More sharing options...
Chariot Performance Posted October 14, 2008 Report Share Posted October 14, 2008 See if the local auto parts store has a cooling system pressure tester. You pretty much do the same thing as a leak down test only on the cooling system. All domes are supposed to stick out .003 to .005 inches roughly. Any other heads which appear flush is probably just that appearance. The accepted tolerance is as stated bove . Quote Link to comment Share on other sites More sharing options...
