Greetings chaps.
I have just spent four days cleaning my sons tank of 30 yrs of gunge to get it ready for him for summer.
After being satisfied that the tank was ok I thought I would rinse it out to get it ready for the tank sealant that I am going to give my own projects tank.
When I was rinsing the tank out I thought I would check to make sure the newish looking tap was working ok.
I put the tap on to reserve and soapy water came gushing out but when I put it onto the on position ,only a trickle came out like it does when you want to piss in the middle of the night but cant.


I removed the filter bowl at the bottom to see if it was bunged up with goop but it was fine.
After further investigation I removed the top tube in the photo and found that the hole was only 3.5mm which is obviously a design flaw in the casting of the tap because the reserve petrol hole ,bottom one was 4mm.
I got a 4mm drill and made the hole bigger and now all is well.
The reason behind my rambling post?
Under no circumstances buy chinese parts for your bike because its not worth the hassle.
I am glad I discovered why my sons bike wasnt running properly ,I thought it was the carb blocked or the tank full of crap but it turned out to be a cheap chinese petrol tap that the previous owner had fitted instead of servicing the original Yamaha tap.
Never to old to learn huh:thumbup:
