I just took my airfilter off to clean it after my last harescramble. The race was very dry and dusty, like baby powder. Anyway, I have a very light dust film in my air boot. I cant see anywhere that it got past the filter. I use Twin Air with PJ1 filter oil, as I always have on every bike Ive owned and never had any problems. I noticed the air boot seems to be held to the airbox with a big clamp, the clamp is tight but I dont know how well its sealed. Im sure its been the same since 06, has anyone had any issues with this? I have ridden the bike about 5 times and this was the first time it was dusty out. Luckily I got a flat on my second lap and had to pull off so I only rode about 16 miles.
