Title: Aniket riding the new 998 V-Twin in a parking lot
Post by: ace.cafe on January 30, 2013, 12:21:51 pm
Here's a link to a short video of Aniket on the 998 riding up and down a parking lot with some short acceleration runs. No mufflers.
I think his smile at the end says it all.

Breaking it in the right way! Fantastic. That is one beautiful machine.

He makes all those "custom" builders look like dopes with all their bolt on crap. That's one talented guy.  ERC

sweet, is this built with a stock  top end? or Fireball?

It's all stock parts, right down to the Iron Barrels and floating bushes and stock con-rods and 28mm Mikarbs.

The Ace parts will go on the next build, and probably Aniket will modify this one later too.

Sounds incredible and looks like it goes fast as hell.  Impressive.

I've never seen the bullet indicators mounted off the nacelle - looks good.

the first acceleration from dead stop...  all I can say is
             
              HOLY SHIT

It's got a boatload of torque, as you can imagine with basically 2 Bullet engines together there.
Probably around 50 ft-lbs of torque at peak. Right in the neighborhood with a Harley-Davidson 883 Sportster.

And there is plenty of higher power capability there with the right mods.

And it looks like a dream!

That bike is so sick!  It sounds amazing too!
VRRROOOOOOOOOOOOOOOOM Cackle Cackle Cackle!!!
Love it!   :D

Coolest bike on the planet, presently.

I am smiling just sitting on my couch watching and listening to it, he must have a bad case of perma-smile...

Tom,
Just being curious here regarding a potential UCE twin fireball. Am I correct in my understanding that the crank position sensor in conjunction with the throttle position sensor essentially 'trigger' the fuel injection and spark by completing/switching an electrical circuit.

Tom,
Just being curious here regarding a potential UCE twin fireball. Am I correct in my understanding that the crank position sensor in conjunction with the throttle position sensor essentially 'trigger' the fuel injection and spark by completing/switching an electrical circuit.

It could be described that way, but it's a little more complicated than that.
Basically the crank position sensor and throttle position sensor are devices which feed data to the ECU. The ECU monitors these and then actuates control functions based on the data it acquires from its sensors.

The crank sensor is basically a hall-effect magnetic "switch" that is activated as each magnetic pole of the alternator passes by it. So, once the engine is indexed to this crankshaft position during set-up, then it "knows" where the crank is, and how many revolutions it is doing.

The throttle position sensor is basically a rotary potentiometer(variable resistor), that provides a changing calibrated electrical resistance all along its range of movement as it rotates with the throttle plate axle. When the resistance at a certain position is received at one of the analog input ports of the ECU, it then "knows" how far the throttle is open(and the rpm and crank position indicated by the crank sensor), and then it can squirt the programmed amount of fuel into the port by opening the injector valve for a certain time period. The injector operates off a regulated pressurized fuel supply that is kept at a specified pressure by the electric fuel pump. It has an electric solenoid valve to open/close the injector, which is controlled by the ECU. The injector has precisely metered holes in it so that it squirts the fuel in precisely controlled amounts when it is opened.

So yes, they trigger it, but it isn't quite as simple as triggering an ignition spark like a set of points. In the old days of very early fuel injection, they had more simplistic control systems that used switches. But, not anymore.

Nice Tom, that would be called "hitting the nail on the head". 8) 8) 8)
