Aerox - Yasuni Z bottom end bogging?

Hello, I'm new to this site but anyway :wave:
Fully de-restricted my aerox a few months ago, Washer and exhaust went okay for a standard 50 without any other mods.
Just fitted my new Yasuni Z Powerpipe, at first it kicks in, and flys!
But when it gets warm, and say from a standing start, pull the throttle back and it will just sit at a low revving, bogging down, until the speed eventually picks up and then the power kicks in..
I have no idea what this problem could be and anyone one here that has a better i idea please post as i cant get my head round it cratch:
:grin:

 

Jetting?

 

I'm not sure, a lot of people are saying that jetting isn't really an issue with just exhausts, but the thing is, i don't think it's jetting because it flys when it gets pst the bogging :/

Cheers

 

You do need to upjet your Carb when you put an exhaust on dude

 

Has feck all to do with jetting! The problem is, you havent fitted lighter roller weights. You've just slapped a pipe on your bike & expected it to work. :grin:

 

All sorted, all it took was a stiffer torque spring in the clutch, quicker off the line now too!

Cheers
