Spark Plugs

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.

What makes sense is to pull a spark plug and check it's wear (you can use any spark plug color chart) if it is normal you don't need to change the plugs heat range.

Sugar Bear is no tech or expert either, agree with the other guys, if 7 has been workin for you no need to change. My own case on my old (28 yrs) 750, I did change to #6, starts and runs much better than before, electrical stuff breakin down?, I don't know. On my 1100 7 is what I use and does me fine. Bottom line, if #7 works for you, no need to jack with it Ride safe.

Ride Safe, Live Long
