Help I think I've done something stupid

[MarJay]

Hello,

I think I've done something silly. I was repairing the threads on the side of my RD350YPVS barrel where the powervalve pulley casing bolts on to the barrel. I think I drilled a little bit further than I should have and a drop of coolant appeared in the hole. I've repaired the thread successfully, and put the bolt back in place but will I need to do anything else to seal it up? I'm hopeful that it will be OK because its only like I've added another drain plug further up the barrel!

Any thoughts?

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

You might need to use some loctite thread sealant on the bolt if it leaks, do not use anything like plumbers tape as it will not withstand the heat.
