I have bought for my bike, a longjia lj50qt-k a technigas Q-tre exhaust. I will be removing the restrictor (I have a full bike licence) so will I need to upjet and if so by how much, the bike is not restricted as it does 50mph on the clock
If you had the standard exhaust on before, then yes you will have to upjet by about 3 to 5 points, but try it first, you may not have to do anything.
