I am new here and have a quick question about installing the gasket while doing a clutch replacement on a 2018 Coolster 125 3125CX-2. When I install the new gasket that goes between the case and the cover, do I install it dry or do I need to use a gasket sealant? Any help would be appreciated. Thank you!

 

Joints with gaskets are usually supposed to be assembled dry, some put a little grease on the surface to ensure the gasket sticks where it is put, while you get the other half of the case on. Others do use "goo" as a sort of belt and braces approach. Only problem with this is some joints have small oil galleries running through them and a drip of "goo" blocking a gallery can be terminal to your engine. I found this out the hard way on an Eiger clutch cover, I used silicone sealant as well, because I was re-using the original paper gasket, a drip the size of a rice grain must have dropped off and had blocked the oilway to the cam, resulting in cam seizure.

 

Thank you very much!
