    Since an exhaust with a lower restriction than stock will cause the bike to run lean. And running lean causes the engine to heat up far more than what's good for it. Guaranteed to fry you piston, piston rings and several other parts. Of course, it can be fixed, but it's near impossible on the 220FI, since the FI isn't reprogrammable. The carb version with an rejetted carb probably is a better bet if you're into such mods. FI is probably best left stock.

        Remove the small restrictor plate at the end of the exahust. You would need an allen key to loosen the bolt and a plier to pry it out. Sound good on higher revs but sounds like shit when idling, plus the exhaust will be more prone to water entering it.

            already tried that but thats not enough .
            moreover doesnt sound good when your rpm is low..
            fixed that back there.
            any other way left ??

                i remember few posts before rahul bhai and praful bhai explained me about afr...
                if we get that exhaust fitted and and make afr rich then ???
                is there still chance for engine to run lean??

                    It can still run lean since the exhaust will alter the fuel requirement differently at different RPMs. Thus even if you get the right AFR while idling, it can still be completely off in the powerband. This is because the fuel map in the FI system has been set for the stock exhaust.

                            See, the amount of money that would need to be spent to get the 220FI running 100% properly on an aftermarket exhaust without burning up the engine is probably too high to justify.

                            If possible, the only option would be to tune the bike fairly rich to very rich at idle and see how it behaves while running at high RPM. I'm not sure if it's possible to measure CO level at high RPM, but that should give some indication of how it is doing.

                            Aside from that, using an aftermarket exhaust is a gamble. Be prepared for an engine rebuild if you get it wrong.

                            Really, I'm not saying you should not do this, but be prepared.
