Due to the advanced materials that some aftermarket headers are made of, this can be expensive. On the DCOE and IDA series carbs they have 2 numbers on them like 50F8. In a two-stroke engine, such as that used on dirt bikes, a bulge in the exhaust pipe known as an expansion chamber uses the pressure of the exhaust to create a pump that squeezes more air and fuel into the cylinder during the intake stroke. If the diameter is too small, power at high RPM will be reduced. If it does then the carbs are too large or you have another problemA 40 DCOE can use as small as a 28mm choke tube but chances are the performance will not be good with anything smaller than a 30mm choke.I have found that a correctly sized 40 DCOE application should always stat with a 30mm choke and do up to a 34mm max.Bigger or smaller than that and you probably have either the wrong size carbs or another problem that is causing you to tune outside of this rangeThis same info applies to IDF carbs as well A great reference book for rebuilding, tuning, etc. Too big and you will always have a flat spot that you cannot tuneToo small and it will always run rich and not make any power.

This is usually accomplished by correct sizing in the design stage, and selecting a proper gasket type and size for the engine. If you do not have enough advance you will have this problem and it will have nothing to do with the carb tuning. then it is time to jet and tune the carb(s) You need to establish if you are running lean or rich. Because of their light weight and the increasing availability of inexpensive tuning equipment,[4] tuned economy and compact cars exhibit high performance at a low cost in comparison to dedicated sports cars. Very Simply..The bigger the number the richer the jet. Shorter springs offer greater stiffness and a lower center of gravity at the possible cost of unwanted changes of suspension geometry. If you are having a problem on a new install it is most likely this problem or one of the steps below See the Vacuum leak tech page for this info. Other standalone engine management systems are available; these systems replace the factory computer with one that is user-programmable. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy, or smoother response.The goal when tuning is the improvement of a vehicle's Detuning is the process returning a modified car to its original factory status, or reducing its performance in a particular area of tuning. Top End Performance has been your source for the best prices on brand name, top quality car parts since 1994. By increasing the roll resistance of one end of the car, weight transfer is concentrated at that end, causing it to slip more than the other. Do not mess with them. Stiffer sway bars reduce body roll during cornering, thus improving the grip that the tires have on the surface by reducing suspension geometry changes caused by roll; this also improves handling response due to faster weight shiftingsimilar to stiffer springs. It should come off of idle good and transition to the main circuit smoothlyIf it falls on its face and will not take any throttle or runs better if you back off the then you could have a few different problems depending the type of carb. The program will feature the breadth, power and journalism of rotating Fox News anchors, reporters and producers. There are alot of theories about setting idle mixture adjustment on a Weber carb to determine Rich or Lean jetting.A Weber will run correctly with the mixture screws from 1/2 turn to 3 turns outThe late style DCOE carbs with the extra Air Bleed Screws on the top take 2.5 to 3 turns to operate correctlySo you cannot say that because it is 1/2 turn out that you need smaller jets.You need to find what is right for that particular engineAn engine with a strong vacuum signal will draw more fuel in with less turns of the screw than an engine with a weak vacuum signal willThis is the kind of thing that throws the "certain number of turns" theory out the window..
