Here's a weird one... For about 30 seconds on the way to work and on the way home on friday, I had a loss of power- it felt exactly like it was losing one cylinder, and it also felt and sounded exactly like it was out of fuel, though that doesn't really fit the bill as it takes off again when it stops exactly as usual- so I doubt the float bowls are draining. Definately not a wet plug. I've checked the obvious suspects- kinked fuel line, negative tank pressure, and just on the off chance I've checked the plugs and fuel filters, all look fine. I'm pretty sure it's keeping one cylinder running, and as soon as it stops, it's absolutely fine. No particular conditions to tie the two, and it wasn't carb icing. I doubt it's rust in the tank as the tank is already petsealed. I did have the tank off and the plugs etc out last weekend for a valve clearance check and some other tidying up, but it's done about 200 miles since and only started with this on friday...

Any options I'm missing out on? It might never happen again but it was annoying, so I'm trying to chase it down. Oh, there were no low-power issues, the bike started strongly the next time I started it, and no telltale dancing needles etc. I tried flicking the lights on and off while it was happening in case it was a drain issue but apparently not. I did have a random flat battery last week during a ride but to be honest I'm blaming rider incompetence and excess load for that!
