It does not include the cost of any parts needed or used in this process. The parts used in rebuilding your engine can be genuine YAMAHA or aftermarket as specified by you. I have owned and run my own NSR250 MC21 since 2001 as well as rebuilding and restoring countless other RD's NSR's, TZR's, RGV'S and KR1's. The time taken will depend upon what parts or additional services are needed. But if no additional work crank rebuilds, barrel re-plating, etc..is required then 14 days is the usuall turnaround time.
