Well I feel a bit better now, I drove over to Canberra Harley after work to book my "Hog" (Piglet?) in for a service. It'll actually be it's second service (it's only got 4000 miles on the odometer) but I don't know how many services it's actually had in it's 21 years.
It does have a new front tyre and a good rear tyre (Pirelli front, Bridgestone rear) and everything works, so once my "Bro's" at the bike shop finish the service they'll take it to their rego testing guy so all I have to do is ride it over to the RTA (DMV) to get it registered here in Canberra. I emailed the seller and asked him if he'll contribute to the registration and he offered me $350, which I thought was fair.
The Sportster tank is tiny, but it doesn't help that there is about half a teaspoon of petrol in it, so I'll take a can of fuel with me and fill it up before I ride it to the shop, while I'd obviously rather push my Harley than ride a Honda (jokes, keep your tampons in ladies.........) I don't actually want to push my Harley either.......... Anyway, after the outpouring of sympathy this morning (not) I thought I better report back to let you all know I've survived another "Fcuk my life" moment.
