Don't use any type of gasket sealer. Use grease. If they still don't want to stay in place use stickier grease.

A little bearing grease will hold it in real nice.

 

I have been told by several people to keep the gasket sealer away from my head.

 

I pinched the o-ring gasket once during installation, just used a little red rtv, has worked good for all last season. I intended to just get a new o-ring, but since it has held up, it is permanant until the next tear-down.

 

Anyone know exactly why rtv is a bad choice for sealing up a cool head?

i used some yamabond on mine and it worked fine. put it on the o-rings and let it set up for about 20 minutes or so before u try to install.dont slop it on or anything but it doesn't take .

i used a little grease and it workled great. run ur bike and let it idle for a min or 2. then shut it off and let cool for a little. re check the torque specs on the head bolts then star it up again. and let it idle and give it a little throttle. let cool and re check again. just make sure u re check urself a few times cas u don't wana be flyin down the road and have ur head leak on u. it's worth takin ur time to work ur way up to full throttle.

I used blue rtv on mine both times I installed my head and have not had any problems with doing so, just dont get carried away with it and let it dry before you install the head

It has some stuff in it that will eat away aluminum over time I think.

It's difficult to clean out of the oring grooves if you ever need to and can make the orings non-reuseable. It also can keep the orings from seating properly if it sets up before assembly.

Certain types of sealers (mainly mated surface type sealers) such as Kawasaki bond, Yamabond, and Honda Bond used for case halve sealing, will cause the o-rings to become brittle much faster than no sealer at all. Normal types of silicone gasket maker dont do this but can be a pain to clean up upon reassembly. If you have sealing problems that keep coming back, use Threebond 1211, but in most cases your better off just using grease by itself.....Jim

Right on, good info.

[bansheeryder21]

Okay so according to dlnoss, grease is the best to use and I know he knows what he is talking about. Now my question is what type of grease to use? My head should get here in the mail today. Anybody?

[Justintoxicated]

Just regular grease, it does not matter much, I just use some all purpose grease. Idea is just to keep the O-rings in place.

[Toomey Banshee]

I just used white lithium grease, threw the o-rings in and greased em in place.

[Gargamel]

dont matter on tpye of grease, hell use vasoline if you want
