650 to 9R

[goforbroke]

I have a low milage 2024 650, 130 miles, runs fine. I ride a boost and love it, but wouldn't mind a 9r to try. 650 to 9r. Has anyone done this? A few questions to see if someone knows.

Throttle body - 650 has a different part number, but similar description.

Asm-Throttle Body,50mm,650 Part 1208674
vs
ASM-THROTTLE BODY,50MM,900, Part 1208809

Do you think the 650 one will work? $550 part. Interestingly the 850 has a different part number and I don't hear of anyone changing that out. 850 part number
Asm-Throttle Body,50mm Part 1208673

Next question. Fuel pump or fuel regulator. Once again to save money, I'd rather replace my existing one if needed with an aftermarket one.
650 K-FUEL PUMP 650 RMK INCLUDES FUEL PUMP, FILTER, PFA GASKET,3,11, Part 2211995

900r K-FUEL PUMP 850/900 RMK INCLUDES FUEL PUMP, FILTER, PFA GASKET, Part 2211994

The 850 one is the same as the 9r. I have heard I just need to change fuel regulator? Not sure what part that is.

Pipe and y pipe - planning on picking up a used one. I think around $600

Tune - any recommendations planning $300

Cylinders - polaris oem with gaskets -$1470 Looks to be one assembly is both cylinders?

Head - OEM $370

pistons rings etc - polaris oem - $720 for 2

valves - $290 for 2

Carls, burandts, and indy specialty sale a 9r kit. It looks less expensive to purchase new from polaris. Am I missing something?

Clutch kit - since I have a p-85, planning to talk to TRS if he has one. Any other recommendations? $465

I think the injectors and everything else is the same.

If throttle body and regulator work, Cost is about $4,215 and I think I'll do it. Please let me know if you have done this or any thoughts or things I am missing.

To clarify, you are planning to do a new top on on the 650 crankcase and replace with factory 9R parts plus all the affecting hardware?

Yes, my understanding is that it should be the same as the 9r, crank body etc, except the clutch is p-85 which some like better. Wondering about those parts I questioned and any other items I may be missing.
