I am about to start the re-build of the engine. Putting the "proper unit" back in etc. I never split the gear box since it seemed to be ok. I have a new set of gaskets.
The question is what gasket sealant to use. Here in the uk I use Threebond 1104 for the rebuilds of the 2-stroke triples. Is this the one to use for the re5m. There may be different names for it in other countries.
