2010 Nytro XTX
Hi, I'm having an issue finding and parts for a 10 Nytro with the stage 1 MPI SC. Since MPI is no longer around and the parts number on the pulley do not cross im running into a dead end. I had a pulley let loose and am looking for a 28 tooth pulley, torque lock and belt. Anyone have any luck finding these from Gates or Grainger? Part numbers would be awesome, or if you have any extras laying around I would be happy to buy them.
 

I found it on Grainger. There are two sizes (width) 1.5” and 0.875”. Mine measured exactly 0.875”. Will be here tomorrow.

I found the belt through Grainger also. They stopped carrying Gates belts but I found a replacement from Continental. Part #39GC64. 90 tooth 21mm wide, 8mm pitch
Conti number CTD8m-720-21. Was around $75
 
Can anyone help me find a mpi stub shaft for a Yamaha nytro for the bottom pulley
Any help can be good
 
Anyone know where to find pulleys anymore? or should i be looking into scrapping the mpi supercharger kit? cause it impossible to find parts anymore i have tons of other “big” pulleys but nothing the size i need looking for a 27 or 28 tooth
