didnt think to try higher octane. ive already installed a bigger radiator, temps dropped a solid 5 degrees. but racing at 225 degrees isnt good for the bike. last season for the most part the bike was stock naked. bike ran around 180. i bought another sv that had everything and swapped over everything. after putting on the fairings and exhause i noticed the bike running warmer around 200. now thats its summer its bumping on 230. ive been told by a few tuning can be a concern. bikes set lean then add a free flowing exhaust the bike runs leaner, and hotter. even tried removing the fairings to test and temps did drop but not much. thanks for chiming in
