Guys, Having never played with the fueling on my bike until yesterday, Dynojet recommended a map to load onto the device, as the closest map to my bike, as my combo isn't available on Euro bikes, but it is on Yank ones. The recommended map is based on a Yoshi, K&N and Eliminator, but will the map work fine with my 2Brothers slip on?? I'm also using a 3db suppressor power tip, as its horribly noisy without. Map 508 for those who are looking now lol. Or would it be best for me to locate a tuner in Essex and get the bike custom mapped? Tuning bikes is a whole new world to me. Cheers Wayne.
