Hi all I have been lucky in purchasing a set of Mikuni 40mm Yamaha TRX 850 Japanese market only carbs , with accelerator pumps and TPS, I intend to fit them to my MK1 SL no 110 , this already has a 600ss flywheel, high comp pistons, full Skorpion spaghetti system and an Ignitech ignition system.
My question is has anyone else fitted these carbs and if so some base jet settings would be very helpful. This is my bike
