Can't you toilet train your bike ;) ;) ;)
Lynx:
My 400 is exactly the same. I've never understood why so much water comes out the exhaust on these. If I've had the bike idling for a while, say to balance the carbs, it is especially bad.
mickwinf:
My bike has a little wee every time I start, I think its true that for every gallon of petrol burnt a gallon of water is produced, so not suprising that some leaks through any small gap until the engine and exhaust get hot enough. Many exhausts have a small hole at the lowest point to let it drain out, just looked at my 500/4 nos exhaust in my bedroom(!!) and they have them.
Clem2112:
Yes, they all do it from a cold start.
Following cars you often see the tailpipe piddling on the road for a while.
Could it be made worse by the water that the ethanol in modern petrol absorbs ?
I expect more weeps when I fit the replica Motad headers and collector to my bike.
Those 4 joints appear to use no gasket/collar.
Oddly my modern bike doesn't seem to wet the floor but it has an upswept exhaust and fuel injection, cat etc. No joints or holes in the lower pipes though !
Johnwebley:
on my 500,all 4 pipes have drain holes,in colder weather they puff steam from them,and the tail pipes,
because of the expense of replacing them,I try never to do short journeys,and always find an open road to get the motor
a blast,normally to over 8k rpm in 3rd,hoping the heat will dry the insides,
