backfiring on the 400
Hi Mike, I'm the other guy on the 400 in Colorado....
Mine doesn't backfire at all, not when I had the stock exhaust, and not
now with the LeoVince exhaust. I have had similar problems once with
an automobile and all I had to do was change the brand of gasoline I
had been using, which at the time was Conoco...I went to a different
quality name-brand gas and the problem stopped. I don't know what
you are using, but you might try changing, and also make sure you
are using the premium fuel.
Just as a side note, my dad worked for Mobil for 17 years, and he
would advise not to mix the different weights of Mobil 1 even though
you can. Runing 10w40 Mobil1 because its Mobil1, would give you
better cold weather protection than if running 5w30 regular oil because
Mobil1 doesn't thicken easily ....I run the 10w40 synthetic in all my vehicles year-round, (but I must confess, if its not at least 50 degrees
out, I won't go riding), anyway.....good choice on your part.
Out of curiosity, where do you live in Colorado ? Good luck on your
backfiring problem.
