January 29, 201115 yr My TY175 has a 250 piston (192cc) with a Boyesen reed and straight inlet to big K & N filter, and WES exhaust. Anyone have any ideas on jetting and ignition timing.Did the 200 Majesty have rejetted standard Mikuni? Thankyou
January 29, 201115 yr Mine is 205cc, WES end muffler, Yamaha main pipe, Boyesen reeds and John Cane ignition, standard carby attachment and standard size TY175B carby. The only rejetting mine needed from when it was 175cc was to go one size different on the pilot jet and slightly richer on the slide cutaway. It already had a smaller main jet than standard from when it was a 175cc and that stayed the same. I can go look up the specs if you want. David
