Please help - detailed instructions on removing/bypassing a50 emissions system

No prob, you get everything ok?

Yep, everything's out and thanks for the direction.

I was going to write an update after a few more weeks of riding to see if the emissions system was in fact the culprit to my months-long mystery stalling issue. So far, so good! Hopefully, that was the final gremlin.

I hate to bust your bubble but the only thing a scooter uses less of is gas, emissions are MUCH higher than modern cars....

B&L - good stuff, and link.  I always assumed this was the case.  My GV250 - all stock, smells NASTY!!!!! when the exhause catches up with me at a red light.  Gross polluters!  But at least the mpg is good and not many on the road. 

Yesterday, I saw a brand new (6 month ago mfg date on the sticker) Yamaha FZ-09 3 cylinder motorcycle with stock exhaust which already had black carbon soot on the tip of the exhaust pipe.

B&L, I'm considering doing the same thing to the SYM HD200 I just purchased.  Should I be concerned about adjusting the carb or the engine running lean after the emission's parts are removed?  Thanks

I am doing the same thing on my 2014 Agility 125 but it has a second big canister on the left hand side. How would I get of this? Thank you for the great write up.
