Bad headgasket
« on: April 08, 2012, 12:59:45 PM »
what the hell I went to put coolant in my bike today and it was POURING out of the head all the way around is there some trick to getting these s**tty gaskets to seal the metal ring won't  crush down so the rest of the gasket in not sealing you guys have any tricks or a paricular order you torque the head nut down in I've never had this problem before

start by lapping the the cylinder and the head to be sure they're PERFECTLY flat....more than likely,thats gonna be your problem.What gasket are you using?
Excuse me, ma'am...but you've got extremely nice legs!!!...what time do they open???                                                                                                               https://www.youtube.com/watch?v=n8tCgN3aryQ

#1 Which gaskets you using.

#2  Torque the head nuts first (ignore the 2 kips ones past 50%)   in a star pattern... then torqe the 2 (Front) kips ones..  50% 75%    100%

#3.  Lap Lap Lap...  Ive never seen a flat Jug   nor do the replaters pay attention to it either.

#4.  after putting in head studs (you tightened those as well right?)   use a straight edge.. to make sure there isnt any material pulled up around the studs.... K5 is good for that one.

#5 Dont forget to loosen the Head mount when you torque it... Met many that have.

they have been lapped the metal ring was at 55 thousands the rest of the gasket was at 49 thou and that's after I torqued it down like I  said it was pouring out uniformly all around the cylinder but I did torque the exhaust head nuts in my criss cross pattern and I new I should have done those last but I  don't think that would have helped anyway because the gasket is a cheap piece of crap and I  should have just bought oem but no I  used ne super gaskets from China I know I'm a dumbass but I didn't hear anything bad about them so I tried them

Never tried Cometic gaskets so I keep my mouth shut as far as opinions. However, I have used dozens of OEM Kawi top end gaskets with excellent results. I do always check the head for warpage. IMO if you have issues with a brand new head gasket, it's not the gasket "quality" or "lack of" that's the problem.

plus 1 on that. I can't keep my mouth shut so.
I only use the thin oem gaskets, (more power) and never had issues. Again I check the head and cyl for straight and square surfaces. There never right and can always use some cleaning up.

the head and cylinder are true its the gasket there is a 6 thousands difference between the metal ring and the rest of the gasket after it was torqued if the head was warped it would only leak in spots mine was POURING out evenly all around the cylinder with no pressure it was never started I'm pretty sure in fact I'm positive it was the gasket and nothing else

Not on that gasket..  It's coated already.  

Positive deck is flat.


Check around studs for pulled up material win a straight edge (I hit my stud holes win a countersink...

If I remember correctly there is a tiny location pin to align the head, make sure that pin is not mushroomed or burred, and make sure there is no debris in the bottom of the pin hole.
