That’s more the idea. I’ve posted a few threads with general questions not because I need an anwser but more out of curiosity of what others use as a common practice! Great info here, thanks to all!
Engine Bolt, Grease or Threadlock?

I used to use red & tacky until I tried Amsoil Synthetic Water Resistant Grease (the blue stuff). Best grease I've ever used.

First clean all the threads on the bolts and engine parts with a tap and die set, use compressed air to blow out the bolt holes after. Should be able to run the bolts in finger tight all the way until they stop, then torque the last half turn or so. I use oil on the flywheel bolt and thread sealer on everything else. Also helps to replace lock washers.

So what oil are you going to use?Sometimes I just like to stir the pot

Haha should I even say? I used the thread sealant specd in the manual. This engine will be apart sooner than later for a better crank so I’ll see how it goes when I take it all apartSo what oil are you going to use?

I use marine grade antiseize for salt water use or blue thread sealant. Also use a small amount of assembly goo on paper gaskets so they dont tear when you disassemble. Essentially making them reusable if you use a small amount each time.

brapperdoodle: Thanks for this timely thread. There is a youtube video where the guy says that he puts a little oil under the hex heads of the head bolts so that they torque uniformally.
(I have heard that putting anything on the threads (except for something which the manual is spec'd for may result in a torque different from that which is spec'd.)
fastgtfairlane: I am swapping flywheel covers on the 701 (which had a oil bump) to a new take off flywheel cover which does not have the hole for the oil pump. I learned about Assembly Goo from the same guy who did that youtube video. I noticed that the flywheel gasket has a little bead of sealant (like ThreeBond 1211 liquid gasket sealant) on the cover side but nothing on the engine side. I like the idea of putting a little Assembly Goo on the flywheel gasket on the engine side and will try it.
Any other observations, suggestions, comments guys?

Funny you say that because I installed an OEM Yamaha flywheel gasket today and it has the little silicone bead on both sides of the gasket. Also I wasn’t going to mention about the torque spec changing, but you’re absolutely correct and I think most people here using grease or anti-seize are aware of that. I have personally ripped threads off bolts using a torque wrench and anti-seize on the threads. One way my Toyota Pickup driveshaft bolt, the other was the engine mounting bolt for my Honda XR650L, both of those times the threads just popped all of the sudden and the nut was free spinning and had to be cut off. So many variables!!!

brapperdoodle: Where do you buy OEM Yamaha flywheel gaskets with the siicon already on them?

It was from Yamaha, I don't mean "silicone" or maybe it is, but you know some gaskets have that "silicone" line directly in the center... This one had it on both sides and I had never seen that before. Should have taken a picture.

The OEM base gaskets have it also.

It's an elastomeric sealant, in use in this country for a few decades called print-o-seal- now printoseal (Felpro)
FWIW...........Ive had the best results with Teflon pipe dope on any fastener that has some length and can stretch to hold tension. Make sure to put some under the bolt head to seal out water. Very short fasteners get Loctite. Fjywheel bolts get metallic antiseize. One good thing about the pipe dope is that its easy to clean up with solvent when you take it apart. I once used aviation "Pro Seal", It was nearly impossible to clean off the parts.

Do you guys have a link for where you buy Yamaha OEM parts including gaskets?
I have searched via DuckDuckGo and all I get is dealers selling skis and ebay listings for gaskets that say it is OEM but does not have elastomeric sealant that augustaf, brapperdoodle and Mikidymac mention.
