The flex fuel thing is really a big expense in the long run, the fuel is initially cheaper but you pay for it in lower economy and parts costs, I know from my time at the parts store the “flex fuel” parts like the fuel pumps are way more expensive, I’m assuming because of their ability to flow a lot more fuel to compensate for the lower btu content in the e10, e15 and e85 fuels.
E10 & E15 really not so much but the e85 probably requires the ability to flow up to about 40% more to meet the proper a/f ratios at the oxygen sensors. The flex fuel pump for my new-to-me 15 Impala is nearly $500 versus standard non flex pump at about $85, big difference.
Luckily our fjr’s seem to work just fine on the e10 & e15 but I would not use e85 in one, I need to look in the owners manual to see if Yamaha even says it’s ok or not but I’m pretty sure not.
