Definitely pulls harder out of 2nd and 3rd gear corners. Finely honed to perfection - the Low Inertia EC997 Eddy Current allows us to discern even the difference between individual cylinders. This kit is finely designed - the perfect needle set for all four cylinders. Good for additional midrange over any kit that uses the same needle in all cylinders!

How to adjust float heights and why would I want to do that? 17mm float height setting To adjust float height:       Sooo.... You read the carb kit instructions and they specify a 15mm float height. Float height? What's a float height?  15mm? How much is that in inches? (it's .590") Does that mean I must do it??? YES! Gee whiz!   What do I measure with?? You can use a set of vernier calipers, if you have them - they are great for measuring all sorts of things, but you can make it even easier with our... Float Level Setting Gauge Measures from 0mm to more than you will ever need!    Easier to use than vernier calipers on carbs. The vertical legs adjust in width and the thin post slides up and down so you can slide the post to the required clearly marked float height measurement.   Remove float bowl screws. Factory Pro gives you replacement allen screws in most carb kits to replace usual Phillips screws. Slide the lower movable leg so that both legs will rest on what would be called the gasket surface of the carb body (if there was a gasket, anyway)   Tilt the carbs so that the floats just flop over towards and into the carb body. Tilt just enough to touch and close the float the float valve, but... Do NOT compress the float valve spring when measuring (only exception is 95-97 zx6r) Test adjust the "L" horizontal arm in the usual 1mm increments and test fit the gauge to see what the float is set at now. (or not). (If we say 15mm and you measure 4mm less than that - you might be compressing the little float valve spring.) At this time, you can set the Float Height Gauge to what you want to reset the floats to. If you are tuning, you'd usually use 1mm increments CV Carbs: Too RICH at full throttle / low rpm (that's the most common in CV carbs) Slide carbs (FCR's) - Float height controls 25% throttle at ALL rpms. If the float height is too low (small float height measurement), bend the tab slightly to increase the height measurement. It's a 5:1 movement ratio. CV: If the float sticks out further, down, into the float bowl, the carb will deliver less fuel (leaner), especially at low rpms and at cruise. Slide carbs: Float height controls 25% throttle at all rpm's, even at redline. You'd generally change the float height in 1mm increments when tuning. It will affect the topend slightly. Maybe 1.5mm leaner float height would require 1 size larger main jet to keep equal main jet fuel delivery. CV Carbs: Too LEAN at full throttle / low rpm (not too common in CV carbs) Slide carbs (FCR's) - Float height controls 25% throttle at ALL rpms. If the float height is too LARGE, bend the tab slightly OUT to decrease the height measurement. If the float sticks out further, UP, into the carb body, the carb will deliver MORE fuel (richer), especially at CV low rpms and at cruise. It will affect the topend slightly. Maybe 1.5mm richer float height would require 1 size smaller main jet to keep equal main jet fuel delivery. You'd generally change the float height in 1mm increments when tuning. When you are done, a multi-cylinder must be all within .5mm (1/2mm) or .020" range of each other.   Nifty baffle plates in the 05 KLX300! This carb type has been around since the early 80's! It's had some updates over the years. It's similar to the Ninja 900'a and ex250 styles. A view from the engine side, butterfly open. Why adjust the float height? Changing the float height changes the level of the fuel in the float bowl. The fuel height adjusts the full throttle, 2k-3k rpm and part throttle cruise, as in cruising around town, trying to be quiet... To give a scale of change, if the bike runs well when cold, but gets a bit sloppy when fully warmed up, lower the fuel level 1mm (i.e. go from 15mm to 16mm float height - remember the float measurement is "backwards"). When do I adjust the float height? When installing a Carb Recalibration Kit tm. When rebuilding carbs. To adjust low rpm / part throttle operation that isn't pilot jet, fuel screw or needle height related. When a bike starts running rich at  low rpm after a mishap or After an overwhelming gravity equalization process occurs. How much is the nifty Float Valve Measuring Tool?

Click here   Note: Measure the "rectangular", taller float (not the lower, "diamond / parallelogram" shaped one) There is ~3mm difference between the 2 different floats! Remember to measure the float height - tilt the carbs till the floats just barely flop over and close the float valve, but don't compress the float valve spring!

	The Military Vehicle Technology Foundation was founded by the late Jacques Littlefield. It is located in Portola Valley, just south of San Francisco. The Military Vehicle Technology Foundation oversees one of the largest and most significant collections of historical military vehicles in the world. Our goal is to acquire, restore, and interpret the historical significance of 20th and 21st century military vehicles. Domestic and foreign combat vehicles such as tanks, armored cars, self-propelled artillery, and other technically interesting mobile platforms are the focus of the collection. We also maintain an extensive technical library that describes many vehicles down to the part level. Aside from the vehicles, there are towed artillery, antitank, and antiaircraft guns. Military support equipment, inert ordnance, and accessories round out the collection. There are over 200 vehicles in the Foundation's collection, many of them exceedingly rare. The updated site will have greatly increased content and information on the collection, as well as information on how to book tours or arrange access for commercial purposes.     To arrange and schedule a Tour.
	The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved. Edited to the tunes of Chemical Residue by Herbie Hancock.
