Hi everyone. I'm new to this so please bare with me. I have a 2009 kymco people s 50. It has a big bore kit, performance variator and weights, carb and hotter ignition coil. This was all installed before I purchased the bike from a friend. I installed a performance starter recently because it would wouldn't crank without kick starting it. I'm unsure if the clutch springs, torque spring were changed and unsure about the size of the weights. So I want to know what exhaust would be right for my application and springs and if I should change my main carb jet and pilot idle also. If there's anything else I should be doing at the same time please let me know......cheers
