I bought a 750 Virago in 1982. Kept it for 8 years, and I did all my own maint. The Factory manual is a must. A good relationship with the guys at the shop doesn't hurt. If you are spending money there, they will talk to you and answer your questions. If you get some good info off the net, share it with them. I sold my bike in '90. It had 77k miles and no problems. It was still running strong in '95. Take your time, double check your work, keep good records.
