I like the factory Champion RJ17LM, if the ignition is a little weak or the engine is a little "loose" you can use the hotter RJ19LM to stay cleaner longer (to a point).
If you're asking for a brand recommendation, there is no right answer.

Thank You MustangFrank for the fast reply. I got this engine used & couldn't read the p/n on the plug. I found a chart but I wanted to get an opinion from a club member. Appreciate it!

Hey Mustang Frank- thanks again. I got this engine off eBay and it ran fine on the bench. It's been on my bike running for about 3 hours now. I don't have any idea how many hours were on that plug prior. Now I'll keep my eye on it when I replace it. Thanks again, Robert.
