It doesn’t offer lights, fenders or a fancy LCD computer but for under a thousand dollars it’s one of the best options available. When compared with the eZip Trailz, which costs even less, the Skyline shines as being lighter weight, having a higher quality battery and a better frame design that creates a more balanced ride. I can also tell you that it runs significantly better on 104 octane race gas.but that is a different story.The eZip Skyline balances price against features and while the components it chooses are on the lower end, it offers a lot of value as an entry level electric bike. I don't know if it actually is, but I can tell the difference between running straight 93 octane and with the added 106 boost. It ran 14:1 even stock and mine supposedly had hi compression pistons added and is also supposedly at 16:1 now. I normally use 93 in it with a bottle of 106 octane boost added. Of all the bikes I own, the only one that requires high octane fuel is my old 1992 GSXR750.
They have the dyno results to prove that the lower octane fuel makes more horse power. The guys over at AF1 racing, the home of Aprilia in the US recommend running 87 octane RACE GAS for those racing the Mille and Mille R. This is for their cars primarily but they are running a higher compression ratio too.įWIW, my Aprilia and my 600 Gixxer both run better on 87 octane. Notice, no manufacturer requires 93 octane anymore save for BMW who consistently require the higher octane rating.
Even with compression rations above 11.5:1. Anything built after about 1995 or so will run more efficiently on lower octane fuel. In effect, intake and exhaust gasses are pulled more quickly through the engine which increases performance.ĩ3 octane is not really needed, and in fact is counter productive on anything with compression ratios less than 11.5:1. Thus, the exhaust “scavenging” can be more effective. Hotter exhaust gasses (as created by the insulation of the wrap) are less dense. Increased engine power (Don't expect to double your horsepower but a 1 - 3% increase is possible)Įxternal heat control is the primary benefit, there is also a potential performance benefit.
Increased plug service life (Depending on design, an Iridium plug could last up to ten times the life of a standard plug with little reduction in efficiency over the plug's lifespan).Improved economy (though this depends largely on how much you enjoy the improved throttle response!).Have contributed to numerous accomplishments through dyno-testing and actual use, their true benefit lies in their efficiency, durability, and improved firing power.Ī lower voltage is required, this reduces load on a vehicle's ignition system (less strain = less chance of failure)Ī larger gap can be supported without increasing load on the ignition system (Larger gap = larger spark = more efficient combustion)Ī more precise spark every time, delivered in the correct position and with the correct timing (More efficient combustion)Īssuming a suitable Iridium plug is available, benefits you are most likely to see are: The increased cylinder temperature will cause the temperature of the combustion chamber components (spark plug, valves, piston, etc.) to rise, and will lead to pre-ignition" and. My bike definitely runs better on 93, your obviously uninitiated to my bike.Ĭan cause knock which will elevate cylinder temperatures.

Does your manual also account for iridium spark plugs too? How about the headers wrapped?
