I am curious if I need to lean out the maps suggested to compensate for the elevation or can I use the maps suggested in this thread and the bike does the adjusting.

dahl0000 Posted August 18, 2020 Thanks for the link. It said it had it but didn't really. It Led me to a guy at Full Throttle Sports in MI that said he has received numerous calls on this part. The only one in the country he guessed:) Thanks again. Quote Share this post Link to post Share on other sites
