dlnoss Posted May 23, 2005 Report Share Posted May 23, 2005 Don't use any type of gasket sealer. Use grease. If they still don't want to stay in place use stickier grease. Quote Link to comment Share on other sites More sharing options...
SANDSTAR Posted May 23, 2005 Report Share Posted May 23, 2005 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?

sandman121383 Posted May 24, 2005 Report Share Posted May 24, 2005 (edited) 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.

jeepman380 Posted May 25, 2005 Report Share Posted May 25, 2005 Anyone know exactly why rtv is a bad choice for sealing up a cool head? 372873[/snapback] It has some stuff in it that will eat away aluminum over time I think. Quote Link to comment Share on other sites More sharing options...
dlnoss Posted May 25, 2005 Report Share Posted May 25, 2005 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. Quote Link to comment Share on other sites More sharing options...
PassionRE Posted May 25, 2005 Report Share Posted May 25, 2005 (edited) Anyone know exactly why rtv is a bad choice for sealing up a cool head? 372873[/snapback] 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 Edited May 25, 2005 by PassionRE Quote Link to comment Share on other sites More sharing options...

bansheeryder21 Posted September 20, 2005 Report Share Posted September 20, 2005 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? Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted September 20, 2005 Report Share Posted September 20, 2005 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. Quote Link to comment Share on other sites More sharing options...
Toomey Banshee Posted September 20, 2005 Report Share Posted September 20, 2005 I just used white lithium grease, threw the o-rings in and greased em in place. Quote Link to comment Share on other sites More sharing options...
