yeah ethanol can be quite a damaging fuel but it is definitely a power maker and a cooler running fuel. Reducing engine temps would be my goal with using it but if the fuel pump and system wont handle it I might forgo testing with it.
You asked adc27 if his bike would pull up in high on pavement and then you compared it to your old 660. This is the main reason I started modifying mine. mine being a kodiak would not even try to pull up the front. My buddies old 660 pulled me from a stop on pavement.
After a few mods mine will wheelie nicely on pavement and that was before the cvt weights and 1.5mm shim. Go find my post about it.
Yes it can be if the fuel system wasn't designed for it.
I agree it's a cooler running fuel and is more resistant to detonation than even pump 93. It's great for high compression performance engines, supercharged or turbo charged applications. However, in a mild engine like the 708 you wouldn't see any power increase, likely u would have even less power output. You would definitely have greater fuel consumption compared to gasoline as it requires a pretty significant increase in volume of ethanol to produce the same amount of energy that gasoline does.
My 16 is def quicker in all situations racing wise compared to my old 660 and any 686 700s I've been around. It just doesn't lift the tires up in high from a stop which is mainly the gearing and clutch differences cause my 660 wouldn't wheelie like that in high prior to those changes.
I read ur post and I'm anxious to see what ur results are with the controller compared to your resistor mods. Since mine won't wheelie with the controller in high but you state urs would after your exhaust mod and resistors, I'm going to make a guess that the exhaust helped u since mine is still stock. I'll be trying it again once my tip comes in the end of this week.
With all that said I'm not a wheelie crazed guy by any means. It is just nice to know if needed or wanted u can stab the throttle and bring it up for whatever reason. Now when I'm out on the trail I've gotten aggressive with it while moving and on a lower grade incline and its brought em up many times. It's just that normal seating position at idle stab that it says no sir lol.
You said u hadn't beat on it too awful much since u believe it to be lean. Did u ever get a top speed reading totally stock? If so I'd be curious to see what it will be with the controller, ur exhaust mod, and the shim and weights. I didn't hit the limiter on either of my top speed runs of 69 mph and 68 on a diff occasion after some weight added and being less aerodynamic. I'm going to see how fast it will go with the controller then the tip and controller. If it still doesn't hit the limiter, then maybe the shim won't lose any top speed but just give the machine the extra mechanical leverage to rev on out.
Look forward to these findings from your testing, my own, as well as anyone else.
Good call KYGrizzly.
I see in the 2016 700 owners manual that Yamaha requires 91 octane fuel without corn.
In my 13 700... 87 and 10% corn is approved.
My last statement was read smwhere else on the forum or a link someone posted in the last couple months. I went ahead and grabbed my 16 owners manual and it states 86 or higher octane is fine for these machines using the r+m/2 method which is the method used for fuel at the stations in the U.S. The lowest I've ever seen is 87.
The 91 octane is research octane which isn't tested the same way. It would be the lowest standard of testing I guess u could say. The highest standard of testing is motor octane. What we see at the pump here and in many other countries is just what I posted above, the average of those two methods hence the r+m/2 formula.
Lastly it does state fuels blended with up to 10% ethanol is ok for our machines.
