What Happens If I Leave Race Fuel In My Motorcycle

Yes, it is difficult nowadays to find gas that's not corn fed especially in certain parts of the country or during a specific time of year.

What happens if i leave race fuel in my motorcycle. Most racers today don’t know what it was like to “fill ‘er up” with leaded pump gas. Also, i once bought a motorcycle with 10 year old gas in the tank, and the bike wouldn't run at all. Also works good for boats, motorcycles, lawn mowers, etc that sit for the winter months with fuel in the tank. Gas tanks have a tendency to rust when not in use, and untreated pump gas breaks down and becomes gummy over time.

Since no components in carburetor fuel systems had been designed for this fuel, the teams could no longer build and test an engine and then store it for future use. And if you have run the engine with bleach in the tank, have the entire fuel system flushed immediately. That said, fuel tanks on bikes tend to generally yield notoriously inaccurate readings from the fuel level. But i am one helluva motorcyclist.

I left my mazda protege unused in my garage for over a year, and the fuel filter was clogged when i went to start it again. Proper feeding of the wild motorcycle can often prove a daunting task. The value of lead far outweighs any downside, unless you factor in the environmental concerns. Understandably, we get a fair amount of questions about lead and why it’s used in some racing fuels.

A vehicle requires proper fuel delivery to its engine to function properly. This is argued by many because the throttle response becomes crisper & is often mistaken for more performance when in truth the bike is making less power on the dyno sometimes by as much. It’s been many decades since lead began to be phased out of pump gas. The race teams quickly learned that the ethanol in the fuel systems created problems with the carburetors and fuel pumps.

Race fuels generally last longer than typical pump gas but often times race fuel is stored for several months between racing seasons. Effectively, race gas offers more choices and more consistency, allowing enterprising custom engine builders and tuners to whittle down allowances they might have to leave in for lower quality fuel (or fuel of unknown quality). My valves have not budged one bit. I run leaded race gas mixed 3:1 with 92 octane unleaded in my drz with 13.5:1 piston.

In fact, the more gas you try to give the motorcycle, the more air will be sucked into the unwanted holes which will ultimately make you lose power. When your motorcycle engine is getting too much air and not enough fuel, it won’t run right. The higher the number, the more resistance it has. This number is used by some fuel companies to trick the racer into thinking the fuel is rated higher, i.e., higher quality, than it really is.

Many fuel pumps keep cool by staying submerged in the fuel in the tank, so if you're regularly running at a quarter full or less, you risk speeding up the need for a fuel pump replacement. The same thing is now happening inside your fuel tank, fuel lines, pump injectors and possibly intake manifold and cylinder head. It started fine, but would not rev and was basically undriveable. A dyno run and tuning session is often in order, so if you are not an experienced tuner, consider these costs in your performance budget.

The “r+m/2” octane number is the average of the research and motor octane numbers for a fuel and is the number displayed with yellow labels on retail level gas pumps. * drain and replace all fluids (engine, brake and other oils, c. Lead and leaded racing fuels. The whole reason that lead was introduced to fuel was to provide valve and top end lubrication.

Here are a few good tips to keep fuel as fresh as possible from one season to the next: I own four bikes, ride more than 20,000 miles annually and commute to work via motorcycle every day. If you suspect someone has bleached your tank, do not start the car. This will minimize the loss of certain components in the […]

All of my bikes have fuel level sensors (including my '82 cx500t and my '79 kz1300, though i'm eliminating that in my build). Removing baffles from the exhaust provides for a freer flowing exhaust, causing your exhaust to become louder and flow more air or flow air faster. Some bikes have fuel indicators, some don't. It must be mixed with fresh gas before the vehicle is stored, not added to already old gas.

It is possible to damage your engine by removing baffles from your exhaust. Standard race fuel (vp c12, c14, sunoco 104, 100ll avgas even high octane pump gas 96 or 100) ran straight on a stock rc51 motor will actually lose horsepower. I don’t have an issue with using e10. Do not try to start it or turn the crankshaft by any means before you do what others have suggested here, especially making sure pistons/rings are not stuck or fused to the cylinders.

I'm sure it wasn't great for the fuel injectors, too. The fuel pump receives the fuel from the fuel tank and throws it into the fuel rail which transfers the liquid into the cylinders using the. My only concession is that i don’t leave the bike standing with e10 in it.
