The Krebs cycle charges only ADP, but the energy contained in ATP can be transferred to one of the other nucleosides by means of an enzyme called nucleoside diphosphate kinase. This enzyme transfers the phosphate from a nucleoside triphosphate, commonly ATP, to a nucleoside diphosphate such as guanosine diphosphate (GDP) to form guanosine triphosphate (GTP).
Bigger jets allow more fuel and smaller jets allow less. The rejetting process figures out which size jets is needed to keep an engine running with the right mixture. Too little fuel and the engine may starve or overheat at high RPMs.Too much fuel and the engine could flood and bog out.hares & Saves. Save. Replacing an exhaust with a carburetor-type engine is more than just bolting on a new pipe. Whether itâs a car or motorcycle or scooter, you are likely going to need to make sure your carburetor is running with the correct jetting for the new exhaust.
I've heard you need to rejet the carbs when you change the exhaust but I wonder why. After all, the exhaust is just exhaust. I can see rejetting if you change air filters, air box or other things that mix fuel and air.But I can't quite see why you need to do anything if you're just changing the exhaust.(I do street riding and commuting, no racing).To me its like requiring you to change the faucet if you change the drain in a sink. can see rejetting if you change air filters, air box or other things that mix fuel and air.
