Rd 350: Neutral switch assembly replacement

[MRDRcycle]

It looks like either the o ring disintegrated or liquid gasket was used on the old assembly. What's the best/safest way to clean it off or is it ok to go ahead and install the new one?

It looks like the gray rtv stuff. I'm guessing brake cleaner and plastic scraper will work, but am not sure what else is behind/around it that brake cleaner might mess up.

Lacquer thinner and a s.s. bristle brush work well.
Cant really tell in the pic, looks to me like Yamabond 4 (hondabond, motoseal, 1204 threebond, etc.)

Thank you! I'll try it out. I've got a can of turpentine and some assorted s.s. and brass bristle brushes laying around. I'm guessing the turpentine might work similarly

Got it done!

Thanks again.

Good job, it did look like the gray case sealer and not silicone sealer...
