Ok I got a serious question. I was asking a mechanic at the Suzuki dealer about mileage and after market accessories. I told him I had cobra pipes and a power commander and I didn't think my mileage was very good. He said I have been doing this for 20yrs. The first thing you should do is get rid of the power commander you don't need it. He said it dumps too much fuel in your system and that is why your mileage is poor. You gain vey little and suffer a lot and it wasn't worth the trouble. He said the same of the pipes they just make the bike loud with little performance improvement. He said the engineers who design these bikes know more than we do and they are designed for the maximum performance and durability.
So, we have a 20 yr mechanic calling what most do to their bikes unnecessary and his bike is stock ( Not a C109). But, he too use to mod his bikes but now has since changed his mind and doesn't.
I want to hear from you guys. What are the benefits and can you prove the bike is better and worth the expense or is it simply personal preference. I am only talking about our bikes (C109) specifically. Also how has your mileage changed versus stock?
