I know a lot of people have put their dyno results on here.. But I was lucky enough to get a before and after. The first one is baffles drilled and O2's unplugged. The second one is the same but with the power commander 5 and the E3 plugs.

Yes it did! it really smoothed out the ride. My tune guy wants to try E85 fuel. He thinks he can get some more power with the higher octane. I will keep everyone updated on that as it comes.

Where do you think that E85 is high octane :confused:

Beside it will take more E85 to go a 100 miles then normal gasoline cheers

yeah I know there is a lot of concerns with e85.. But it is 110 octane the same as race fuel. It is way cheaper then race fuel which is a plus. The reason you get less mileage is cause of the extra power. The prob with the flex fuel cars is they are regulated by the EPA. My tune guy gained about 40 hp in his non flex fuel car with a proper tune. I figure it is worth a shot. If it dont work then you can say told you so but if it does well good for me lol. plus with the pc5 it has a map switch so if I am somewhere without E85 I just flip the switch and now I can use gas.

You get less mileage with E85 because you have Less power and have to turn the grip farther. Also running higher octane in a low to mid compression motor that doesn't need it gives you Less power as well, you don't get more power from higher octane. Higher octane burns slower to prevent detonation in High Compression motors, which you don't have. Vics run best on 89 octane ;-)

The reason why you get less gas mileage is because corn e-85 produces less BTU's then gasoline...

E85 is horrible for bikes, destroys seals, damages Pistons etc. The AMA is currently fighting as well as the automotive industry the push to get to E85 because of the cost of making engines capable of consistently running E85.

it concerns me more than a little that a "professional" is espousing the idea that more octane=more power. That's only the case if your engine actually requires the stabilization of higher octane to prevent detonation.

Also, +1 everyone has said about ethanol in general so far. It's all accurate. Might wanna find a new tune guy.

I knew as soon as I said anything about E85 it would be a fight.. But like I said in a my previous post Im gonna try and if it dont work then you all win and I would be the first to admit it. But if I win I guess I would like a little respect and an apology.. Im not trying to step on any body's toes. but what is it gonna hurt to try something new. Isnt that how things get better is to try new things? how do improvements get made. so your all saying that if someone came out with a new motor or cam or piston that it is worthless and its not worth trying? why not try its not your bike its mine. I just dont understand why anyone needs to be so negative about it. its still new there are a lot of people trying different things to gain horsepower. I mean sh*t why does nascar run it now? is everyone scared of something new. the worst thing that is gonna happen according to you is that it wont run and my gaskets erode and I have to replace them.. well screw me cause I tried something different.

Quick question without trying to rob your thread, I don't have a manual handy but does it not state to use 91 octane?

This is another thread on its own. Vic recommends 91 to make it idiot proof. Premium is only needed in high compression engines, we're not quite there. Your engine runs best and makes the most power on the Lowest octane you can use without getting detonation or "pinging". Using premium when not needed can cause carbon build up on pistons and valves from unburn't fuel.
