I have spent the whole winter making my FJR fast, I have the dyno runs to prove that it the fastest one. First I removed the restrictor named Air Box, then drilled holes in the head pipes just before the converter to help get better exhaust flow. Still there was more that I needed to do. I replaced the sparkplug wires, why would Yamaha be so dumb as to put resistors in the wires? I used #10 Romex but had to cut the wires at the coils and use wire nuts. Now I am getting someplace. I went to the local airport and got some jet gas and that made a 78.5 horsepower increase above the 48 horsepower all the other changes made. Real progress is being made now. I also disconnected the ABS hydraulic pump so the engine wouldn’t waste power running it. Suddenly I realized that as the engine went faster the air coming out of the exhaust blew harder. Eureka, the next solution for a power adder just came to mind! I used some gas dryer ducting and some hose clamps to connect it to the exhaust pipes then ran it up to the throttle bodies where it could force more air into the intake just like a supercharger. I don’t have dyno slips for these runs because it ran out of numbers for the chart and only made a straight line at the top. I think it should now run at least 325 miles an hour! Write to me and I will send you the instructions on how to make these changes so your FJR can be fast too.
