There's tons of information in several older threads - I've read most, but would love to see current opinions concerning which spark plugs are probably better for the XB engine ('09 XB12). How about Brisk plugs (correct heat range, etc.)? I run a BOR10LGS in my Blast (have run for 18 months), and it's been a great plug...wondering if any XB owners run them, etc.

In addition, there's a fairly lengthy, older thread concerning adding a ground lead from the battery to the coil screw (or the braided frame cord mount) as being helpful for the electrical system. Any contemporary information on whether or not that is needed or a good thing to do?

Thanks in advance for any help/info....
