Aprilia SR50 Scooter 2T.
Got a Malossi 70cc Sports kit, Yasuni R exhaust, stock 17.5mm carb and stock airbox with a Stage 6 HPC MKII Crank (If this matters?) How much in terms of % should I increase my main jet and do I need to increase my pilot jet also? Main Jet is 53 stock and Pilot Jet is 32 stock.
Any help is most appreciated
It sounds and performs really well when I go from 3/4 throttle to WOT. Loads of power and performing great. However in low revs it's spitting like this without much power even when the engine is warm.
Idle seems fine and turning the idle screw out or in makes the idle run slower so I think that's perfect. The needle is an A22 with the clip in the highest position which I understand is the leanest already, that's how the Carb came from the shop?
My main jet is at 80 would changing this to a lower jet help?
