Devl Max you are so right. I'm 64 years old and I have been modifying bikes since I was 16. I had bike in the old Autorama shows years ago. I have Harley's that I have modified high performance after market engines that then required beefing up the transmission, clutch modifications, starter modifications, drive belt to chain conversions, etc., all to handle the engine modifications. And lets face it, I can tell you from first hand experience, those highly modified bikes are always more problematic than a stock bike. All motorcycle manufacturers spend extensive research & development for optimum safety & reliability. I guess I just can't leave thing alone. But then again it's not a bad hobby if you can afford it and you are realistic in the cost & outcome of any project.
In the case of my Vmax I also changed out the factory shocks to the Wilber shocks for a more comfortable ride. The handlebar risers were done back in 2012 & that along with the shocks have made my bike so much more comfortable on long rides. Not for everyone but I designed it for my personal preference. The risers that are on my bike now are a second set I had made because the first set did not provide the seating position I was after. At one point I changed out the handlebars to a bar that had my hands twisted inward in the hope for a more comfortable ride. The Vmax has such a hard pull that it was hard to keep my hands from sliding off so I went with a handlebar that is more of a straight drag bar style only 2 1/3" wider than stock. I have experimented with many modifications on several bikes over the years that the outcome was not what I expected so I started over until I got what I wanted. Some times an Idea in your head does not translate to a functional modification after it is designed & put in use. The fun of ownership is making it you own.
