Them fat tubes

[ali]

Afternoon all.

Can anyone tell me the function of the big rubber tubes that seem to lead from the bottom of the carbs to the little plastic box mounted on the l/h side of the frame???

One of mine has a bloody great split in it and I'm trying to work out if it's affecting anything (especially starting the bike). She's sounding a little lumpy on warm-up but it may just be the dropping temperatures.

Cheers,

Ali

It's a vent tank for the carbs. Bit like the breather on the engine. Lets any vapour build up escape.
Try taping the split to see if the idle settles. Doubtful though, unless the breather is affecting the air bypass.........

Thanks Nelly, much appreciated. :)

Just wanted to check they weren't anything similar to vacuum tubes found on cars.....
