- 2006 Yamaha Nytro ER
Last month I extended my 2006 Nytro to a 144 x 1.75, and dropped 1 tooth on the driveshaft from 9 to 8 teeth.
I feel like I still want to drop my top sprocket from a 21 to 20 or 19. I am still able to clock 150kph on a lake with a tailwind. I know its actual speed is slightly slower for the yamaha factor, and for the 8 tooth reading faster than true.
Does anyone have the proper part numbers from Yamaha for a 19t or 20t sprocket that will fit the jackshaft, or are all the Vectors sprockets the same spline / chain type as Nytros? Or,who is a decent aftermarket sprocket reseller in Canada that I can avoid the stealership.
I know my top sprocket is a 21t as I happened to get a picture of it when it was disassembled. Does anyone know factory bottom size, be it 38 or 39
