The farkles have value and cost quite a bit to purchase retail. Add the price of those on the 05 and see what it will cost new to install them on the 07. It really adds up.
To me a replacement instrument cluster with 0 miles is a red flag. Of course it is critical to see the maintenance records on the 05. If none are available; I'd walk away.
There is always another bike out there. These two are absolutely not your only option. Take your time and get exactly the bike you want for the price you want to pay.
Agreed -- whatever damaged the instrument cluster was either a severe accident that probably damaged a lot of other stuff besides or, uh, I dunno -- precisely targeted lightning bolt from an angry Zeus? Vengeful ex? Where's the old instrument panel? And "debadged" smells a lot like "repainted".
The point is, there's obviously a story here you're not getting. Dealer paperwork is easy to fake -- how the hell would you know if it's true? Besides, they're asking way too much for a damaged bike.
The farkled 05 is obviously the better choice. The mileage is of little to no concern.
As far as maintenance records, I don't place much stock in them. Again, these are nice to have but very easy to fake. Definitely not a deal-breaker. I'd much rather rely on my own assessment of the bike's condition (I suppose this varies if you're not all that mechanically knowledgeable).
And let's face it -- these are pretty tough bikes, and there are no models earlier than 2002. Short of crashing, there's not a whole helluva lot that can go wrong even if they're neglected.
Wear items like chains and tires are obvious and can work in your favor as bargaining chips. Same with valve checks -- if the owner doesn't know when they were checked or you don't quite trust the records, it's just another way to keep the price down.
If the thing runs OK and oil is fairly clean, it's not worth fussing so much about the blinker fluid records or the seat fart logs.
