You will be ok with the 2003 parts, the 2002 Vin number is actually for 2003s sales and year etc..Barrett has clutches(Performance Shop parts) if you want to go that route. Possibly American Sport Bike. And of Course the Dealer.
The Stock Clutch pack parts will work just as well, especially if it's just for street riding. Might want to replace the Ball Bearing the Rear Needle bearing the Inner race and Inner & Outer Thrust Washers. Make sure before you install the New Clutch Cable to get some Inox Lube and put about 20 drops inside the Cables Housing. Let it run from one end to the other and that cable will be very Smooth to operate.
If you use Oil or other types of Lube W/D 40 and such it will Evaporate or become Sticky and hard to operate, possibly wearing out the cable prematurely OR it may snap it. When [Assembling] use some Transmission Fluid inbetween Plates and Clutches to wet the parts so it does not start up dry.
Good luck on your Mods.Make sure to have to correct Tools to open up the Clutch Basket. After all is done make sure to change the fluid at about 500/miles. You can break in the New clutches with Formula from Harley. Then at 400 to no more than 500/miles change to Redline OR your preferred Brand as long as it is at Least Synthetic 20/50.*Jimi
