Just finished installing the Two Brothers 88cc kit on my 2004 CRF50. The bike runs like crap, found the cyl head gasket leaking on the right side. Everything is torqued, anyone ever have this problem? Will some high temp rtv fix it or is there a better head gasket out there?

Ok, well I went to the honda dealer talked to a guy in service, and he said a factory head gasket wont hold up to the 88 kit. I put some high temp rtv sealant on it, and it fixed for about 30 min. It is leaking in the same spot on the right side. I have had no luck finding a better head gasket, anyone know where to get a head gasket the will hold up?
