The internal parts are really clean. This is the magic of synthetic motor oil. I use Mobil 1 0w40.
I replaced a total of six shims. This brought all of them back to the original factory specs. My bike has 48,000 miles.
When the project was completed I had one hand on the starter button and the other on the kill switch. I new if I made a mistake this was goiing to cost a lot of $$$ to fix it.
I turned the key on, held my breath and hit the starter. She immediatley fired up, no metal to metal sounds. It idled really smooth. I put my helmet on and took off slow at first down the street. She ran just fine.
Next I opened her up and wound the RPM's up in 1st three gears. It runs a lot quieter. I'm going to adjust the right side next week.
