I was going to get a 07 Harley then pulled my head out.

Looks like Im going to get a 07 Yamaha Road Star Warrior.

Dont care so much about mpg, as I do low end fun grunt.

I'm really not sure on this one. I'd imagine cost/weight/complexity is a factor with the other bikes (although I find f.i. far easier to work with) . With Harley's, I'ts probobly more tradition, also the reason they use out dated technology all around. In the future there is plans for Harleys to be F.I. as well though.

For the smallest of bikes, they run f.i. so they don't need a battery, sensors, and related heavy bits, they are pure simple machines.

Hopefully someday we'll also have F.I. ULEV lawnmowers, or plug in ZEV lawnmowers and such it will probobly be too late by then anyways.

Vmax dosent have much down low. Its all pretty much made on the top end. Plus couple that with way nasty forks and brakes and the jacking shaft drive. They kind of a suzi bike. Ive heard rumor that its suppose to be redesigned for 08.

I think must new Harleys are FI.

I think what is most amazing about bikes not being all EFI across-the-board is that Kohler makes closed loop EFI for some of their garden tractor engines.

Think about it: You can buy a garden tractor with closed loop EFI, but not all motorcycles.

Dosent suprise me a bit that all bikes arent FI. Anybody that builds up there big V-twins or other FI bikes. Dumps the FI, O2 sensors and all the other EPA stuff. And alot of these folks dont or wont care what the EPA or anybody else has to say about it.

After I get my Warrior. It wont be stock for long.

carburators are cheap to build, and the molds, and facotries are already set up to build them, the cost of a replacment carburator from honda for my motorcycle (if they still made them) would be around $120, a 4 wire o2 sensor can cost almost that much, so how much are tiney fuel injectors going to cost, and the computer, throttle body? fuel injection on motorcycles is going to come in a few years, but unless you want a really crude system, or a large engine (like a riding lawn mower engine 600-800cc) that can use off the shelf parts, making a fast, small fuel injected engine is going to take time to work out it sounds like.

Ryland, have you ever considered adding fairings to your bike? While browsing the internet, i stumbled upon 50cc race bikes haha, they're actually quite speedy! 100+ mph from around 20 h.p.! Considering that, these fairings must be quite efficient since my bike has almost twice the horsepower, but much lower top speed...



I'm playing with the idea of trying to make a similar fairing for my 400cc bike, the only problems I see are cooling to my air cooled engine. With no temperature sensors, I see no way to measure this either.
