dont depend on the speed displayed on the speedometer... coz its not accurate.. tune the bike up.. then see if it'll not improve..

you need a bigger carb jettings. like 107.5 or 110. its because there is no back pressure but ur acceleration increased ryt?

Hey bro, if you changed the pipe and only the pipe and did not made any changes on the carb settings, try to check the o-ring on the exhaust port if it is there or if the nuts are tightened decently otherwise the exhaust fumes might be sneakin out between the ex port and pipe manifold... This is one of the few necessary evils that could cause that kind of problem... You sure you just changed the pipe without touching anythin aside from it? If it does'nt resolve the issue then it's time for you to call me so I can provide assistance through mobile phone as you're way too far from where I am located... 0922-895-0069

nice tip xproject.

rejetting also helps.
check the for sale section for jet kits.

i will try to find exhaust gasket, my exhaust gasket is also
worn out...

Sorry for asking. is it free flow one?
The same thing happened to me. losing the power drastically.
If not doing jetting, the pipe need inner mods so the exhaust is not too free to flow.
Then gain the power back.

@junex

jettings will only need be done only if you have free flow exhaust pipe.
if youre using stock, you can rejet to #105 which is the jet used by AC sniper.
