Does performing basic service on a new bike void warranty?? I took my 14 SGS to my local dealer a few weeks ago for the 1,000 mile checkup and they overfilled the engine to the point where I had oil spitting out of the air cleaner. I checked the oil when I got home and it registered way pass the hot check mark…. Overfilled tranny too! Luckily for me the ride home from the dealer is only 25 miles so I don’t think any damage was done other than a nasty air filter and messy jeans. I'll be doing this task myself from now on and I am told and read somewhere that warranty is good as long as you do them at the proper intervals and keep receipts?? I think there is a log on the back of your owner manual to record services but not sure if that’s for dealer use only. I have done services on my other bikes but only after warranty expired. Any advice?? By the way, the dealer did apologize but I don’t think I’ll be taking my bike there again.
