Idle issues (with video)

[maxp]

I had planned to sort my carbs out (for the first time) when I had a weekend or two to myself, but that moment seems to have come sooner rather than later as the situation has gotten worse.

I plan to remove them and basically give them a thorough clean, and reset everything to 'factory spec'.

Ive just been outside and taken a video of the bike in action (or should that be in-action). If anyone has any specific pointers on the likely culprit then that would be appreciated, if not no worries.

I'm no expert by any stretch but to me it sounds like it is being starved of fuel??

Have you checked fuel lines and tank? I say tank as mine sounds like it has a sand pit hidden inside
If your tank sounds "sandy" when shaken, try running it without the tank (bodge some make shift direct feed for the petrol) and see if it runs any better.

A confusing update -
I put half a bottle of redex into the tank after I took the video, ran it for 2 x 5 minute idle sessions (blipping the throttle whenever they fell into the lumpy sub 1000 range).

Left it for an hour, came back, thought sod this Im going for a ride to see if she's the same and oddly as you like it ran fine for the whole 40 minute jaunt.

Bloody bikes

It had almost a full tank, a mere one week old, and I cant believe something like redex could 'fix' it so dramatically so i'll just have to wait and see.

Having the same issue with mine, carbs need cleaned I think. Redex did sweet fuck all to help but for 2 quid it was worth a bash.

If the problem comes back, give the bowls and pilot jets a clean - don't forget to check the float heights whilst you're there.

If no better after that, try connecting a fuel source directly to the carbs (missing out the pump). If it runs fine then, it's either the fuel pump (rare they go) or the pump relay (less rare to go)
