In particular the one on throttle body cleaning - mine was pretty dirty. Toothbrush and a liberal spray of throttle cleaner solved that. One of the pipes was really hard to budge, and when it finally did give, all knuckles straight into the timing belt cover - not nice. Musta taken of 3 layers of skin on my hands that day. I also replaced the fuel filter, and got a nice surprise when I went to inspect the air filter - 2x washable k&n panel filters, so I gave them a good wash and back they go. Most interesting airbox setup I've seen yet. The idle isn't quite perfect as yet, it's a touch high, but it's a marked improvement from what it was.
