i have a 1998 techno 200, when the bike is lent on an angle the petrol drips out of a pipe, at the bottom, i read somewhere this pipe was to give it pressure but not sure. i have had the float out made sure it is not bent, it still leaking is there a cure for this? thanks

Don't know if the Techno uses the same Mikuni carb as the Rev-3, but on later bikes the fix is to simply connect the two overflow outlets together with a single piece of tube.

the techno and the rev3 have the same carb.

thanks sirdabsalot. know i wont get any more petrol patches onmy drive from when it is on the stand

When the floats are properly adjusted you should not have any leakage, and you should never have fuel come out the vents.
