Usuallly, upjetting will result in a decrease in fuel economy.
Real world applications vary because no two bikes are the same and no two roads, routes are the same.

Badbob's mileage went down, as did mine. On both the GZ and the scoot.

LOL!

Just want to ask guys and girls here WHO DID DRILL the exhaust...

How many holes did you drill that the sound was pleasing to you?
How many holes did you fill back?
How long did you drive your bike with drilled exhaust?
Any problems with engine, due to drilling? (any rejetting, fixing engine, bugs...)
What is your opinion now, after ___?____ about drilling? Would you recomend it?
Have you changed the exhaust from the stock?

Thank you for answers, I would really like to get feedback from you, who did that...
