RE: SPARK PLUGS
personally Harley-Davidson sparkplugs worked fine for the most part, for a stock engine. But, if that's not the case you need to expand parameters! I personally now use Autolite, after recommendations by my tuner. I was having some difficulties with stock plugs, and moderate RPM roll on's. So far I've seem to cure the problem with the change. I find them to burn exceptionally clean, virtually no carbon buildup on cold engine starts like I did with the Harley-Davidson plugs. Also after a good days hard ride I find porcelains, to be exceptionally clean and residue free.

I have tried them all and found the stock HD plug works best, and has the smoothest idle.

I just changed mine and used the Harley plugs. I'll spend the $6 dollars at the local dealerfor the peace of mind. I'm not sayingyou have to use the Harley plugs but the service manual says "no substitutes". GoodLuck
