I also inherited my 00 standard from my brother. He bought her new in 00... It had been sitting for 2-2 1/2 years on it's sidestand,
outside with a tarp over her. My brother was trying to change out the fork springs amongst other things when he started getting sick and it was left with the tripletree caps off under the tarp through two New England winters. She was in sad shape when I received her.
After rebuilding and sincing the carbs, new progressives front and rear, all fluids, tires, SS cables, etc... she fired up and also smoked heavy. I did the same thing with new gas and seafoam. After a 125 mile run she had no more smoke and been smoke free since.
Hope it's as simple as that for yours.
Now that I have her running alright... I'm just getting to the various parts that have unfortunately rusted because of the weathered abuse... poor girl.
