docc Posted June 9, 2014 Posted June 9, 2014 It has been the ethanol free premium fuel that has made the biggest difference for mine.
gstallons Posted June 11, 2014 Posted June 11, 2014 For anyone in the States Google www.pure-gas.org and look for stations in your home state to find ethanol free gasoline . I use it in all my air cooled engines. Get ready to pay $$$ for it too ! 1
docc Posted June 11, 2014 Posted June 11, 2014 Locally, the pure gas premium is 30-40 cents a gallon more (about 10%), or an extra two bucks on a full tank.
4corsa Posted June 11, 2014 Author Posted June 11, 2014 Just checked the website map and not a single ethanol free station in NJ - thanks Gov. Kris Krispy! Hopefully a few tankfuls with Engine Med Rx will do the trick.
4corsa Posted June 22, 2014 Author Posted June 22, 2014 Ok so I get to mark two threads as "solved" in one weekend - that'll never happen again! So after installing the PC III and loading the map for Mistral Exhaust / stock air box, AND running through two tankful with Yamalube Engine Med Rx, I have no more pinging! I know I should have been more scientific and tried them separately, but I have no patience. The bike immediately ran better with the PC III, but still pinged a bit at the end of the first tank with the Engine Med Rx. But by mid way through the second tankfull, I couldn't get it to ping no matter how I opened the throttle or at what rpm. So to recap, I'm running Mistral Exhaust with K &N filter on the stock box, Power Commander III with map loaded for the Mistrals (richer map), and now using Engine Med Rx regularly (will probably use every 2nd or third tankfull moving forward), and my Scura has never run smoother or stronger - such a pleasure to ride now! Thank you for all the help!
