fx ho pump in gpr?
What all has to be done to install a 05-07 fx ho pump in a 01 gpr? Really im just needing the stator section-I assume the shafts and bearings are different?? Thanks

no issues. the ho pump that everyone uses and came stock in the 05+ gprs is the fxho pump. gpr uses a longer driveshaft withe the 2" spacer that was also stock on the fxhos and the later gprs

There are 2 items being discussed here
1) the FXHO or more commonly referred to 05 (GPR) pump is yamaha's updated pump. The only difference with it is the inner hub size is larger. it uses the same seals, bearings and driveshafts as the older pump
2) when yamaha introduced the GP1300R in 2003 they added a 2 inch spacer. The spacer can be used with any of the Yamaha pumps. If you add the spacer you have to have use the new style intermediate shaft, introduced in 2002, and you have to use the 30 in driveshaft. The only year that didn't use the 30 in drivesahft was 2002, in 2002 Yamaha used a 28 in driveshaft.
If using the new style pump it is best to also use a large hub impeller, either a solas Dynafly or a Skat impeller.
You can use the 05 pump without the 2 in spacer and also vice versa, you could use the spacer without the 05 pump.

Pump im buying is out of a 06 fxho-complete including driveshaft. Im installing in 01 gpr hull. So would the driveshaft from the fxho be the correct length and spline to use (with the spacer) in the 01 hull? I plan on using a skat impeller(based on earlier conversation with you(thanks for all the info you have helped me with)
