I hafta agree with MurphyBrown here, you are obviously starting out on trips that are FAAAAR too short, it's not good for your Spyder at all!!! So, your Spyder is trying to tell you that you really NEED to plan on longer trips from the get go!! :yikes:
Even if you only want to go to the grog shop, plan ahead & take the long way there & a different (longer if possible) way back!! Explore all the alternative (& longer) ways you can travel from home to wherever, but make sure you plan & aim for more distance every time!!
Oh, just a thought about another thing that might be contributing to your issue besides the wheel alignment - are you using the right brand & spec oil?? And what mileage are you travelling before each oil change? Apparently that can have an impact too!
A little background here..... I too had this mileage problem when I first got my Spyder, but the Dealer I purchased it from was very helpful in properly explaining the issue, so I was pre-warned & well prepared. When I picked it up at 9 am, on the dealers advice I took it for a quick spin around the block just to get used to it; travelled about 400 miles & took most of the day to do that (gotta keep the revs varying & avoid rapid brake/accel, etc) but I didn't leave the state....

After I'd seen him & finalised all the paperwork once I got back (at around 7pm that evening) I left it with him overnight to get some extra farkles fitted before collecting it & taking it home the next morning. When I arrived to collect it, I discovered that he'd brought his Spyder out so he could take a short break from work & ride with me for part of my trip home (nice fella, hey!) He left me to go on alone & went back to his showroom shortly after our third gas refill & lunch, so I went straight home from there - took me another 8 or so hours to do those last 500 miles, but I was trying to vary my speed & revs a fair bit still! :dontknow:
Anyhow, & getting closer to the point about oil (finally

) I haven't looked back since, altho at my last service I was advised that I should book & leave home for my next service at least 800 miles before it falls due; apparently they don't think I should hold up the scheduled oil change even if doing so will put it half way around the 1600 mile return trip to their workshop....

pps:
Sooo, some food for thought there.... I'll leave you to it!! I gotta go cos I'm meeting for a meal with some friends just down the road in about 4 hours, but if I don't leave soon I'll never cover the 300 mile trip I have planned to get me there, & I'd hate to be late! :thumbup:
