I've been having issues lately with the connection where the fan sensor attaches to the radiator on my SV. I loosened it a few weeks ago and it was majorly cross-threaded; as a result of taking it off it wouldn't re-tighten properly and would leak pretty badly once the bike was started.

I have since had the thread in my radiator helicoiled with a steel thread but although the bolt now tightens pretty well, there is still a very small bit of leakage coming from the connection. I think the helicoiled thread is (very slightly) too large for the bolt.

Tomorrow I am going to try adding some PTFE tape but I was wondering if a smear of 'Instant Gasket' or some other sealant compound would be good for sealing the connection better?

Or has anyone got any other recommendations? Any help appreciated!
