1104 is the stuff I used when I changed my crank.

I use Honabond for everything, like the results and consistency of the sealer when liquid.

1104 or threebond, Yamabond seem to be very similar, but not as runny.

Apparently Three Bond make sealants for many motorcycle companies.

Threebond 1207B hasn't failed me yet and is excellent for modern crankcases.
Threebond 1104 is a cheaper alternative and does good work when joint surfaces are worn or uneven but I believe is now discontinued due to lead content?

1207B is the stuff Honda spec, it's not cheap but the amount you use is so small I fail to see a reason to use anything else.

I used ThreeBond 1211 on both my car cylinder head and the NSR crankcase. I've got to do more driving and riding before I'll make a recommendation, however.

I resealed the dreaded camshaft/rocker box oil leak on my KTM with Hondabond, already lasted longer than factory KTM sealer.

Reading thumper forums it was the most recommended sealant for the job, even KTM shops recommend it Smile
