Dirt bikes don't normally run with a steady throttle off road and they weren't designed too. Fully open the throttle valve. The idle circuit is generally activated by vacuum under the throttle plate, which causes a low-pressure area in the idle passage/port thus causing fuel to flow through the idle jet. You can do it yourself if you have the tools and a compression gauge or you can pay a shop to do it for you. He replaced mine with that one, including injectors. The engine burns the air that enters the PCV system so, if the fresh air port is prior to the MAF then, this air will enter the engine without being measured by the MAF and adverse engine operation may occur. 6 horsepower and 6.

Throttle Position Sensor (TPS) The electrical circuitry to both the APP and TPS sensors is the same. One example of this is when the engine is modified, or a different throttle body is being used than what originally came with the engine. The theory is to heat up the throttle body in cold weather and to cool off the throttle body in hot weather. As always, keep the connectors for these parts separate and label them if necessary. All the electrical connections plug back into the same places, the coolant hoses screw back onto the EGR plate, and the PCV hose slips onto the new throttle body. Loosen the jam nut and unscrew the throttle stop screw all the way so that the throttle blade closes fully against the throttle body itself.

If I understand correctly when looking at your photos of the composite intake there are two holes (orange circumfrance) beside the EGR port/throttle body end in which coolant passes through. I already did the regular bypass but it's still hot because of the other coolant hose on the left. I have seen this become blocked with debris / dirt in the fuel system and cause a high fuel pressure condition. The intake air flows through the air filter, intake boot (snorkel), then through the throttle body, into the plenum, then through the runners and into the cylinders (see diagram). That way the TB doesn't get quite as hot, allowing the intake air to be a couple of degrees cooler. Why do you need fuel injector cleaning?
