Harleys are great bikes, but it's people who give them a bad name. Looking down your nose at Jap bikes isn't just confined to some Harley people, in fact some Italian bike owners are probably the worst.
Back in 1980 I had just bought my second CB750, a K1, that needed some work. There was a Ducati repair shop around the corner from where I worked in Lidcombe, in NSW, so I walked in, and asked the proprietor, Ian Gowanloch, if he fixed Jap bikes? He just laughed and said, "Yeah, we'll fix it alright, with some petrol and a box of matches!" and his dopey mates all had a big laugh at my expense.
I ended up taking it to a Triumph guy, Lenny Henderson-Smith, who was a great Triumph mechanic, but not so good on Honda 750's, as it turned out. He was happy to give it a go though, and he told me that the great Ian Gowanloch used to work at Frasers Ducati until he was caught stealing parts and selling them, and did time in jail for it.
Lenny wasn't the best 750/4 mechanic, but at least he was honest, unlike that arsehole Gowanloch, who's still in business today, as I just discovered. I don't mind Ducati's, especially modern ones (old bevels look nice, but are sh1t build quality) but I wouldn't ever buy a bike from Ian fcuking Gowanloch.
