Yamaha part numbers -- WR400 -> 426 Conversion
Posted March 22, 2007 - 03:18 AM
I'm doing a 426 conversion on my 400 and i got a quote for all the bits using new OEM stuff from a 2001 WR426. One thing i noticed with JJHayesIII's list of part numbers he has posted a few times on the forum is that the part numbers for the piston & crankshaft assembly are different. Which after checking the catalog his parts were for a 2002 model.
Here are the part numbers:
2001 WR426: 5JG-11400-10-00
2002 WR426: 5JG-11400-20-00
2001 WR426: 5NG-11631-00-00
2002 WR426: 5NG-11631-10-00
So my question is. What is that 3rd number for? are these parts actually different. Does anyone know of any changes that would have affected these parts between 2001 & 2002.
Just wanna make 100% sure before I order the parts
