it seems to have been the wet season in the uk for a while,
i use my cane every day and it has been wet,last tuesday the bike started to splutter like she was dropping a cylinder or two, so my first thought was coil or plug. MORE SPENDING MORE EBAY
She then cleared and ran fine for a day,the next day i had to stop for fuel, when i removed the filler cap the tank neck was full of water got to work and dried the neck out. Ran her home that night and she coughed and farted all the way home.
The weekend i had the tank off and the breather pipe from the tank neck was squashed up and some of the water had got in the tank, so the fuel from the tank was put in the wifes car (it`ll do no harm in their ), repaired and re-routed the breather, new fuel filter and new fuel and she is running sweetley again.
the moral is start with the simpleist and cheapest every time.

 

ah the tank overflow it was , my 87 the actual tank breather internal choked up
so I drilled the cap to make sure no internal vacuum

 

your right sprock it is the overflow, over the christmas break im going to have the tank off again and clear them all out and re route them

 

shhhesssshhh do I miss those Christmas breaks and boxing day on the other side of the pond !.

Here in the USA this year we just get the Wednesdays off ! .... no room for major


Let me know how it goes with clearing the internal tank breather pipe if it's
blocked

 

will do sprock, looking forward to over a week off
i have got myself some welding wire ready if anything is blocked

 

You'll need wire the thickness of a paperclip. I think welding wire may be too thick.
FWIW

 

your not wrong shadow,but luckily where i work we have some 20g welding wire not sure what they welded with it, but we used to do lots of fabrication work, if thats to thick i will find something i hope
