Since i've just bought the Husky TE510, I thought I'd better add a husqvarna forum section!
Jaydee Motorcycles did a fantastic job preparing the bike for me, and its just done 150km so far, so time for that first warranty service.
Something that you may not know, is that you can get the warranty service done by any qualified mechanic/shop if you are a bit away from your Husky dealer.
I've only had one hiccup with the bike, and that is wearing through the shock protection flap that covers the swingarm. I guess the combination of the large standard rear tyre, going to the 15 tooth sprocket, and a bit too much right hand action caused the tyre to expand at speed and rub it through. :-(
I put a temporary fix on today (plastic from an ice cream container), and kept it below 80 without causing any more wear.
I'm ditching the standard tyre with the service anyway, and replacing it with the Kenda trackmaster, which i'm quite a fan of, and it will be a much smaller tyre, 110, maybe 120 where standard is 140 which is huge!
I changed the oil myself at around 75km's, and there was a fair amount of metal on the magnetic drain plug, and the oil was quite dark, so I think its probably better to do that early rather than later. Especially when the engine is new.
