[QUOTE="CA G-Man, post: 1160741, member: 36805"] As suggested by my tongue-in-cheek "correction" of bigjohnsd's post above ("defective[B] [S]tire gauge[/S] technician[/B]"), I truly believe the problem in my case and likely many others is ignorance by the techs. Both of my tires were bang-on 31 PSI, which I think would be unlikely if a tech tried to inflate to the factory specs (36/42) using a defective gauge (how does the same gauge read 5 PSI/14% low on the front tire and 9 PSI/21% low on the back?). The 31 PSI is also suspiciously close to a "standard" pressure for car tires. Pretty sure it's not primarily an instrument issue. Coincidentally, when I took the bike in I asked the manager at the counter if they could install 90-degree valves for me. After checking that they had some in stock he said "sure - I've written it on the work order." Guess what - I got straight valves! [/QUOTE]
