For anyone with a Yosh RS3, air box mod and Pair valve removed I have a custom map. I spent the time and money on having it tuned on a Dyno250 and decided to sell the exhaust to make room for a Brock street megaphone kit. The map made an extra 5hp on my bike over the one available for download from Dynojet. Send a PM if you want me to send it out via email. Hope this will help someone.
