Saving Fuel

[BrokeStonedBiker]

what are the ways of savin fuel. no wise asses please.

 

i know that jetting bigger and boreing bigger the the main things that will suck it down.

 

does high compression burn more gas?

 

does advancing the timing burn more gas?

 

and does shaving the head have anything to do with it?

 

the more i can get out of the tank with out having it run to slow is a good thing.

that all depends. technically, higher compression makes more power so that would make it more efficient and therefore use less fuel. However, I would believe that the power gains are so minimal that fuel consumption would not noticeably change.

 

Same goes with advancing the timing and head shaving is more beneficial for indians or aborigines.

Basically look at carb and jet sizes. Your jets and needle limit the amount of fuel being sucked into the motor. Anything that makes you jet up is going to consequently (sp?) burn more fuel.

It defies the laws of nature. You cant go faster and get the same efficiency on a well tuned bike (maybe if it was running rich) IMHO. You would have to back off from the mods and restrict intake and exhaust flow to use less fuel.

Increasing your compression/ shaving your head and advancing your timing is about one of the only ways to gain power without changing your fuel consumption. Increasing your compression gives you more complete combustion by raising the thermal efficiency. Also, advancing your timing you are getting more complete combustion without comsuming more fuel.

 

oh yeah, check out this, once I get the cash flow I will most likely do this:Dial-A-Jet

Let's talk about efficiency for a moment, and I'll use my diesel truck for example. The same should apply in any motor driven situation.

 

My truck stock got 14 city / 17 hwy. I put my computer module in. Basically, the module reads the air intake and increases the fuel flow, turbo boost, increase the pulse of the fuel injection and the adjusts the timing of the fuel injection. Even more simplified, it gives it more fuel for a longer period based on throttle response. So, more fuel, hmmm, less mileage cause I'm using more fuel. Nope. The motor runs more powerful, and the byproduct of more powerful is more efficiency in this case, so less throttle pressure is needed for the same task as before. Less throttle pressure to maintain 75 than needed before. Now, my truck gets 17 city / 21 hwy. Less fuel consumption. I got around 500 miles in a full tank before, and I can now break over 600. That's a definite decrease in fuel consumption.

 

The same would apply to our case, just not near as drastic. Only, our problem, is instead of maintaining, we're always adding to. It's full throttle all the time, so we add mods and up the carbs, we're still full throttle, so the benefit is much harder to see.
