When I joined I said I would be asking a lot of questions, which you folks have been real helpful with. I also said that I would try to contribute when I could.
Over the years I have pulled a wrench lot of different bikes, both mine and others.This came to mind as I was changing the plugs on the R3
One trick that has been around for years is to put a dab of anti seize grease on the threads of spark plugs when you replace them. Not expensive, but can make them screw in easier , seat properly, and prevent damage to the threads in the engine. I have had to replace a lot of threaded spark plug inserts. Not easy by any standard. Expensive if you take it to a shop.You don't need a bunch just a dab where the threads start , it will work its way up as the plug is screwed in. A penny and a couple of seconds and save a lot of money and having your bike tied up in the shop waiting its turn.
