Spent some more time riding since the conversion today.  It is hard to quantify but it just feels better.. everywhere running E85.

But it really is amazing how being 20 degrees warmer than last time really help in starting and warm up.  Today it was just as if it was still running gas.  Started right up, and after a minute or two off the choke just fine.

One thing I may do is either stiffen the springs on my TM48 up a bit or move to a 60 pump jet as I think a little more squirt will be the last thing to make it tuned to a tee.....  It has better throttle response already, but just feels like a little more will help a tad - make sense when you consider its about 30% leaner with this fuel on the accelerator circuit like all the circuits...

Got one more thing to do before hitting the sand..  going to Vic's favorite soon...

 Was wondering if there was any more info on running E85 on the DS650's? Benefits running on a stk motor? Jetting recommendations? Benefits adjusting the timing?  I've a little late to the party, but have never run it and would like to benefit from others knowledge

4 oz. per 10 gal.

Specific Gravity E-85 .785

With Mystery Oil and E-85 .78528

Ethanol is corrosive, but not very much. Gasoline is corrosive too. Ethanol is biodegradable in water. So it has a tendency to contain and attract water. It is not the corrosive properties of ethanol that can cause damage to your vehicle; it is the water which can rust a vehicle’s fuel system from the inside out. Today’s distilling processes are superior to way back when. We now have better techniques for drying out ethanol or reducing the water content.

On side note, gas contains water too. Ever hear of dry gas?

Ethanol cuts down the lubricity of oil, I would run a full synthetic oil if using E-85 full time.
To protect seals and add lubricity to the metal surfaces, I would also use Marvil Mystery Oil.

Jetting:
E85 requires 30% more fuel flow.

If running a 150 Mikuni main jet, increase size to 170

Raise needle 1 groove

Pilot screw out 1 turn more

Powerjet works bests for final tuning

Ignition timing: 32 degrees high compression    34 degrees  stock compression

Because E85 is not always E85 at the pump, if running high compression, buy a E85 fuel tester.
In a stock motor, if E85 is lower, lean out the fuel requirements with the powerjet.

Because of the cooling effect with E85, for best results, higher compression and more ignition timing is necessary.  Too much cooling will actually result in the motor producing less power.
