HMF full system. Leaking at the head.

[Stoke88]

I just bought a used HMF full system off ebay. Its in really good shape and got it for a good price. I put it on today and started it up but its leaking at the head. The nuts are tight too. Is there any gasket type thing that goes on there? I know my warrior had like a metal "o ring" that went on before the header. Any help is appreciated.

Yes, you need to replace the gaskets. Prolly the same thing as what you mentioned on your warrior. Its a copper colored gasket you can get at your dealer. Will need a thin flat blade screwdriver and peel out the old ones then set the new ones in there then they smash down and seal as you tighting the header bolts.
