As the thread title says: Don't trust dealer techs. [EDIT: ...not all of them of course,] I know a couple of really good ones but most seem to be marginally competent at best. I've posted before about the dealer where I purchased my KTM 1290 SA. Over the first few weeks of ownership, I found numerous assembly errors. Then no less than FOUR different techs rode the bike and came back saying they couldn't reproduce a 40 mph handlebar shake that was moving the bars about three inches either way if you let go - and did it absolutely every time under any conditions. Latest is the tech who serviced the Triumph Tiger 1050 I just purchased. The chain was tight as a bowstring, even with the suspension uncompressed. I asked about chain condition while looking at online pics before purchase and the salesman had a tech check it out - so they had two chances to get it right. After riding for a day, I figured out why the rear brake is so bad - the disk is covered in chain lube. I also noted that just about every bike in the shop (new and used) has white sideplates on the chain, due to spraying with lube. This is only on the outside, however - indicating that whoever is lubing the chains doesn't know what's they're doing. My guess it that every single bike in the shop has a lubed rear disk.
