Want to keep your bike as stock as possible but want a smoother ride and/or hate it cuts out on you randomly? There might be a solution for you: *Switch to Shell gas.* I had switched from 93 Octane to 89 Octane when I started to use Shell gas (based on recommendation wife got for her BMW (car) and trusting Shell 89 more) so I could never gage just how much of the smoother ride was Shell. Was running late for work before Thanksgiving and didn't want to stop to put gas and at work then realized riding it to the closest Shell may be a gamble and went back to the Exxon by work, because it's probably fine anyway, right? Well, the longer I rode it the more I hated it, aside from riding rougher it sometimes cut out when I rolled behind people and pulled the clutch all the way in to disconnect power, something it hasn't done in the previous 10k miles. Back on Shell gas today, and it's much smoother again, nothing changed but gas, I can be sure of the difference now.
