my little scooter came with an egr,
thats an exhaust gas recirculation system. sounds really complex but basically its a pipe that comes out of the exhaust and puts some of the exhaust fumes back into the air intake.
it to do with being greener and giving a cleaner exhaust gas.
honestly i can see where they are coming from but its a 125cc scooter that does 120 ish miles to the tank and the tank is 6.5 litres.
its not exactly a gas guzzling v12 that does 6 to the gallon.
as i had mentioned earlier the bike shop welded the pipe and it blew up and off so i was driving about with it off and i had noticed that the bike felt nippier.
it didn't go any faster still 50mph but the throttle was more responsive and the bike would pick up speed quicker.
i put it back on to test and sure enough the bike felt sluggish and unresponsive.
i would turn the throttle and it would slowly pick up speed. even the handling felt slow.
so for me i personally felt it had to go.
so i followed the the vacume line back to the manifold inlet and blocked that off by bending it over and sealing it with cable tie and cut the pipe,
unbolted the egr from the back and took out the pipe connecting to the air box and put on a small air filter to stop dust and crud getting in to the carb and engine.
finally i followed the metal out let pipe to the engine and unbolted that. since i didnt have a egr blocking plate i fashioned one from the blown pipe by liberally beating the crap out of the remaining pipe left with a hammer to seal the pipe. the bolted that back in place. ta da a blocking plate.
once i has that sealed and cable tied i took it for a spin.
i hadnt noticed it so much before but at near top end the throttle was bogging.
it wasn't till the other vacuum was sealed and i was out on it did i notice.
still no faster but it has made my bike more responsive and able to pick up speed quickly and basically a joy to drive.
