Hi,
im facing this kindof weird problem. the bike is obnoxiously loud when warming up at idle. my bet is it is because of secondary air injection system intended for warming up catalyst. and since i dont have it any more i dont really need to warm up exhaust. anyone tried to disable the exhaust air injection system?
or maybe have a good advice how to warm up bike without pissing off the neighbors?

The bike is with decat mid pipe+stock exhaust

If you open the throttle a tiny bit, the volume goes way down.

indeed. bike then sounds exactly as it should. do you have an idea why is it so?
