I've actually got the Gustaffson windscreen working quite well on my 650 after adding SAENG micro-swirl edging to it. I'll update the product review with the details. But I had a very bad phone support experience with Gustafsson yesterday. I need to say something about his customer support, so that others aren't taken by surprise.
Some history: I had tried a Gustafsson windscreen for my V-Strom last year. It didn't work out, and I returned it after one test ride. My next credit card statement showed no refund. I called him. He dug around and "found" the returned screen and said he would process the refund. Next monthly credit card statement arrived - no refund. I called again. "Bookkeeper oversight" according to Gustafsson, he'd take care of it. I finally received the refund, but three months after shipping the screen back at my expense. And he still deducted the 25% restocking fee after holding on to my money that long. That aside, his screen for the AN650 sounded promising, so I decided to give him another try.
After riding with the Gustafsson screen for about a week, I noticed that it didn't line up exactly on center. I measured, and the tape measure confirmed that it was offset 1/4 inch to the left. This bothered me, especially since the screen had cost almost $200 delivered.
I called Gustafsson and stated the problem. He started off on a somewhat sarcastic note. So my screen was off 1/4 inch? Well, well, well. A whole quarter inch? So what did I want him to do about that? Then he launched into a tirade. He noticed that I'd returned a V-Strom screen. If he'd noticed that when I'd called to order the Burgman screen he wouldn't have sold it to me. I was obviously one of those fussy customers who couldn't be pleased. One of those guys who just like to try things out and return them. (???? I hadn't asked to return the screen.) He then ordered me to ship the screen back, and if it was in perfect condition, he would deduct the 25% restocking fee and refund my credit card. If it wasn't in absolutely perfect condition, he would send it back to me and I would "own" it. (Again, that wasn't the purpose of my call.) He then went on for awhile explaining that minor imperfections were common in all brands of windscreens and most people don't even notice, explaining that he doesn't pay any attention to what Givi or Clearview charge for their screens - he uses better material that will last longer and charges what he should. He insinuated that I was the only person who had ever complained about one of his Burgman screens. He sounded extremely agitated, and didn't really leave me an opportunity to talk - he was basically unloading frustration toward me and my piddling complaint.
I finally got him to understand that I'd like to talk. He was quiet for a while, and I talked, explaining that I did feel that a screen that cost that much should line up perfectly, and that I had NOT encountered that issue with the stock screen, the Givi screen, or the Clearview screen. I also pointed out that I had not returned those screens to the manufacturers, but had sold them online after deciding that I wanted a different solution.
His ultimate offer was that I could return the screen (my shipping expense). If it was in perfect condition, he wouldn't deduct the restocking fee, and he would make me a new screen. I told him I'd get back to him if I wanted to do that.
I went out to the garage and remounted the screen, and I was able to get it aligned closer to center. Not spot on - but pretty close. If he had just worked with me on that, I'd be OK with the whole deal. But after listening to that tirade, including derogatory remarks on my behaviour as a customer - I'm not at all OK with Mr Gustafsson's attitude toward customer support. I test rode the screen again last evening - it is working well. I slept on it. I'm going to keep the screen. Hopefully it will last for as long as I own the scooter. I am going to avoid dealing with Mr Gustafsson again. Ironically, that will make him happy...
