I will share my experience. Getting 40yr old base gasket scrapped off of al head was a real pain. I may have scratched it up a bit. First I put it back together and used a light touch of some non-hardening sealant in spots on base gasket. When I got back together I get some oil leak by back of this base gasket when I take it out and drive for a while. Took all apart again and new gasket, without messing with any sealant. But still get some oil leaking. I noticed someone else's u-tube rebuild slobber this lower base gasket up with grease, not sure if that is good thing but it might at least help avoid hours of scrapping sealant or gasket off if you have to get at it again ;) I did learn they say to put sealant on rocker assembly surface where head-bolts go, there are those copper washers, a couple o-rings on the head bolts that maybe I should have replaced. The oil travels thru these head bolt areas to rockers above. May have to try again, ugh.
It's a pretty notorious spot for leaking! I haven't had any issues with it yet, but getting the old gasket off was definitely not fun. It had hardened so badly.
@@BonesMcoy I got it fixed by just adding slight sealant to cam block, clean up copper bolt washers and adding tape to one of the two bolts missing the rubber down by the thread. I think it was the sealant on the cam blocks to avoid oil going down in bolt holes and collecting. What a relief!
I hope not the new owner would be disappointed in me. At the least, it had more giddyup after I replaced it thanks to the compression increase. And never gave me any issues.
Well buddy i bought it from you lol. I got the motor pulled out of the frame right now and I’m gunna take it into work and check the piston bores , hone it and make sure the heads are not warped at all. Shouldn’t have blown the same gasket out again but it did .

Did you reuse the rings home the cylinder with fresh rings
Nah, the cylinders still have honing and I don't have/can't afford a dingle berry. The bike is sold now 🥲 I miss it a lot
Someone know the torque specs for the head bolts?
3.15 kg-m, 23 ft-pd
How much torque do you put on the head bolts?
3-4
Sorry never seen your comment there, did you still need the spec? It's in my repair manual
Guess what… head gaskets blown on that motor again.

@@ProjectFound999 hahaha that's great! Good to know it's in good hands.
It was my first one so I hope you won't hold it against me.
We’re you putting new piston rings on or did you just take them off ?
