I have a question with regard to spark plugs.
I have a vstar 1100 classic, 2003. I am the only owner.
I live at 7500 feet above sea level and my bike has been rejetted, by me, twice. I forget which Jets I am using (from Maxair), but the bike is running well. I have K & N air filter and Hard Chrome Big Straights.
Today I went down to a local bike shop to buy new spark plugs. The guy there sold me #6 spark plugs (NGKBPR6ES) instead of #7, which is in the Vstar manual. The guy told me that he always uses spark plugs that are 1 number hotter than recommended.
Does this make sense or should I be switching these spark plugs for a number 7?
thanks for the help.
