Sealing Crankcases?
I'm in the process of rebuilding my old ninja 250
http://www.svrider.com/forum/showthread.php?t=261713 The manual calls for "Sealant: Liquid Gasket TB1216B: 92104-1064" which is ridiculously expensive. Originally I planned to use Permatex ultra black, but some research shows that's not a great idea. I see people swearing by ThreeBond 1194 and ThreeBond 1121. Has anyone here had experience with either of these products? OR any other recommendations for sealing them up? |

I use the gray stuff called Honda bond. But before I put it on I clean the case half a with break clean. And I use a scotch bright to rub them down. As I put the Honda bond on I rub it around some to make sure there are no oily spots. And only leave a thin film of sealant. You don't want any squeezing inside the case. Let it set up for a little while to form a skin. Then put the two halves together.

Yamabond is also excellent.

Here's a tip that is especially good for the clutch-side cover. Put a more permanent gasket sealer on the side of the gasket toward the crankcase, and use an RTV on the side toward the cover. When it is time to change the clutch, the RTV will allow the cover to pop off cleanly and the gasket will not be destroyed. The gasket has basically been glued to the crankcase. To reseal, just rub and peel off the RTV and apply some fresh.
I have used this technique for 35 years, it is great for any cover you may want to remove cleanly later.

Why has no-one mentioned....
...After applying the sealant, mating the surfaces, and snugging all bolts with minimal pressure -- wait 15 minutes before finally torquing the bolts to spec. This allows the gasket maker material to further set up and slightly harden before being torqued down to spec, ensuring that less of the gasket maker is squeezed out of the crack and lost.
