Re: replacing an R1 stator
Stators go like clockwork on R1's at 25,000 miles. I changed mine on my 03 r1. There is a thread on the r1 forum that outlines changing it. You are going to need a three arm puller to get the flywheel off, no way around it. The flywheel is simply pressed onto a tapered shaft, the crank. No keyway, so you can imagine that that mother ****** is on there good.
You will need to modify the puller to go into the holes on the flywheel, being carefull not to mangle the flywheel or the end of the crankshaft. Yamaha might make a puller, im not really sure.
The hardest part is getting the flywheel off, everything else is cake.

You have to pull the flywheel. The stator is behind it.

A jaw type puller might work but is not the proper tool for removing a rotor/flywheel....The centre of the rotor/flywheel is threaded, what you do is remove the bolt holdin it onto the shaft. Then use the proper threaded puller (or simply a very strong bolt with the right thread size and pitch)to pop it off the shaft.
Done it before many times not on an a 2000 R1 specifaiclly, but thier all basically the same...And yes they are pressed on pretty tight

Re: replacing an R1 stator
When I do them I try to do it quick while the bike is still hot. All the expansion from constantly heating up and cooling down of the crank tends to really stick those rotors to the taper...They all POP! off but some of them take alot of force and really POP OFF!....

Re: replacing an R1 stator
your stator is on the Left side. You will need to take all 9 allen bolts off the stator cover. You will need a 16mm x 1.5mm puller hardened grade 8 bolt to pull the flywheel off, but good luck sometimes these things are so stcu on these models (poor desing by yamaha) that you might have to HEAD THE FLYWHEEL to get it off while usung an Ipamct wrench and the puller bolt. You then DO need a new gasket and about 2 qts of oil or whatever it takes to restore lost oil during the job.
hope this helps.
