Do not start that bike. This is the best opportunity. You will have to get everything out.
The method you described above, will work great.
I ran Virgin redline for about 500 miles and then I dumped it completely
The next time I dumped 500 miles later, it still had a little bit of a greenish tent so I wouldn’t worry too much. It will take you a couple changes to get it all out.
All my miles are very hard and near red line I basically have less than a 20 minute drive to where I’m ripping it up.
I always ran 300 V fresh for track weekends though.
What I’m getting it is your 3000 miles if they weren’t very hard, may not be the Engine killer that it was for me
OK, I think I touched on everything you asked. Good luck, buddy!
