Random Fuelling Issue

[Az]

I'm riding along a duel carriage, pretty much flat out and it starts to become a bit more sluggish and the revs drop slowly. I naturally turn over to reserve as it imitated the same symptoms of when the bike is running low on fuel and needs to be turned over to reserve via the fuel tap. The bike ran fine on reserve and the revs picked back up again.

I then realise that I topped up yesterday and i've only done 40ish miles since yesterday.

So… Assuming my fuel consumption has got really really bad for what ever reason, I pull into the next petrol station and top up, the bike only fills up with £5 something, so it definitely did not need to be switched over to reserve and had a decent amount of fuel left in the tank.

I switched it up back to the main tank via the fuel tap and it didn't happen again on the last 15miles (roughly) of my journey home.

Do these things happen? Is it something I should pay much attention to? I don't want to be stuck in the middle of no where because i've got some fuelling issues.

Bike's a Suzuki Bandit 600 mk2 and it's never done this before. Bike was running fine before this issue and is running fine now (done roughly 50miles today).


TL;DR - Bike started to splutter like it needed to be turned onto reserve, I had enough fuel in my tank and did not actually need to turn over to reserve. Should I ignore it or should I be checking my fuel lines and/or carbs?

Given it picked up when you turned to reserve. I would guess at some crap in the tank, that has got stuck round the intake.

Hi

As above, or a bit of water. Or possibly a blocked fuel tank breather (not enough air getting in to replace the volume of fuel being used - slowing to switch to reserve gave it a chance to catch up, and afterwards you weren't pushing it so much) or blocked fuel filter .

All the best
