First, has anyone noticed a drop in their mileage after using power vision tune? I have gone through several tanks, and where I was getting 45-50 on freeway, with my Vieds, I am now getting a solid 40. Before you say I was running lean, I had the Vieds adjusted to where the plugs were a nice light brown color. Plus I could adjust each cylinder individually.


Second, my bike 2007, XL1200L from the factory, manual says I can use 87 and higher gas. Most other models, min of 91. Has anyone used 87 in their bike? I ask because living rural, I keep about 10 gallons of 87 octane for when things get low. Mowers, power tools and car. To have one be 91 cuts down available amount of gas to store. In case you wonder, it get turned over and used up frequently before storage becomes an issue.


Third, I am trying to come up with a quick and convenient method for locking up my full face helmet to the bike. I have a couple ideas but they look goofy when the helmet is not lock on them, so they are a no-go. If you just hang yours on the handlebar, without locking, please refrain from commenting, because I will not consider that, for many reasons. What I was trying to do was have essentially a built in helmet lock that stayed on the bike and I did not have to dig through the saddlebag like I do now, to find the cable. I prefer NOT to lock it using the D rings.
What do you guys use, and or suggestions?

Thanks
The last time I filled up I used 85 octane for reasons we wont discuss right now. The difference from my usual octane is when I gun it, it has a rattle/ping noise from my valve train area. If I ride it easy, everything is fine indicating to me if I want to use the full range of power from my engine, using the highest octane possible is mandated. If I plan to ride it easy (never gonna happen) then I can get by with a lower octane. Does anyone use an octane booster with no bad effects by chance and can you share it with us?

take a old fuel pump hose see how much water it takes to fill the length of the hose to the nozzle

Hmmm, I don't seem to have one on hand at the moment, nor have I ever. Nor will I ever, most likely. Just not something I foresee a need for.

Why not show us? If you have a hose, prove it. Toss us a bone!

Otherwise, I think I'll go with the API data.

Only down in Baja for my VW bus in the early 1980's. Some of the gas we got from barrels was maybe 78-80 octane, IIRC. All I can say is when I ran out of octane booster, it was a total bitch to start my van in the morning. The minute I got back to the US and put higher octane gas in, starting was again very easy. This was back in 1984, and we had to get gas from barrels, filtering it through cheesecloth.

From then on I always made sure to bring plenty of octane booster, and a can of starting fluid, just in case. Today, Mexico's gas is pretty much on par with our US blends.

i figure that the first 2 gallons will be left from who ever used the pump last so why pay for it if i am not going to get it.
I don't understand this at all.

I bet all pumps are the same the world over.

In the UK weights and measures people visit a petrol station with calibrated containers and check the pumps are delivering what it shows on the dial. No way will a pump in the UK under deliver by 2 gallons.

He might be figuring the pump to the dispenser will be full of the previous buyers gas fill. No telling how big the pump is or how much its hanging onto till you direct it to fill from a higher octane tank. Could be very little or it may be up to a gallon who knows? It's a logical argument and worth further discussion. Someone who works in a service station and has in depth knowledge on the subject would be helpful.

hose can be 8.5- 18.5 ft. 10.5 ft is most common all are 3/4 inch. so take a 10.5 ft length of 3/4 inch hose and see how much water it holds and then think about what amount the pump itself holds

Not 2 gallons ... on any typical coaxial "Gas Station" dispensing hose. The Vapor Return take a large portion of that space.

I don't care how much the pipe holds, when I pull the trigger and serve 12 litres (3.17 US gallons), that is what goes in the tank of my bike.

What service station employee even pumps gas today?

I think the API data is about as good as we can get for valid information.
