Well put. Plus one.

 

I agree with that comment that working on your bike is half the fun of owning one. Good for you. Oh yeah, your plug did it's job.

 

My Honda dirt bike plugs always did the same thing. Like others said it just means it's doing its job.

 

This metal shavings question reminded me of a product I use in my trucks & the wife's car called Tufoil, it's a teflon based additive that has rave reviews for car & truck applications. In cars this stuff if amazing and reduces wear & friction. They claim it works well in bikes also. Anybody ever use it in an HD ? The principle has to be the same, only use less. V-8's use 8-10 ozs, so 3-4 ozs for a bike should be fine. Any thoughts ??

 

I've used Tufoil in my pickups & cars for 20 years. It's good stuff and can be used in any 4 cycle engines (I even put a couple ozs in my lawn mower). Just don't use it during the break-in period.

 

I used to run Slick50 in my cars back in the day. Since then I've read a lot of tests and reports stating that those type of products don't do much more over the long run than raise the cost of your oil change. The way engines are built now a days with better tolerances, etc., using an additive just doesn't add up to a whole lot more longevity for the engine. I'm sure I'll have a lot of people disagreeing with me here. I just use good oil and make sure it's always clean.
