So do ye pull the tank and manually remove the carbs and empty the bowls? or do ye turn off the fuel tap and leave the bike run til it uses the fuel in them and the lines? or another way like leaving it rot in there lol. Im more curious than anything.

I just leave mine running with the tap in the off position for a few minutes. I use my bikes regularly though.

Les your method seems a bit labour intensive. But as you say if you know you wont be riding it for a while its definitely best to do it that way.

I usually do it the same as you Zeus. Its just handy, although i do wonder does it cause any damage with the increasingly lean mixture til it cuts out

Just stick a jar under the bike and crack off the drain screws on the float bowls, if you're worried about it. Bear in mind if you're using premix though, that there may be a slight oily residue left from the mixture that could, eventually, turn to a gel-like substance... after several months!

Personally, unless you think it's going to be 6-12 months before you use it again, I'd just drain the float bowls. It takes seconds.

As for Les's "labour intensive" method... really?! On an MC21 race bike it's two screws and a couple of minutes max to pull the carbs off the manifolds! (You don't need to disconnect the throttle cables.)

Andy im under 30, anything that takes my generation "a couple of minutes and 2 screws" is labour intensive lol Very Happy
