Dump valve problem

[Ryan6926]

I have a forge 007p forsale £60 delivered running the yellow spring

This isn't the for sale section bud

Next time perhaps use PM?

Guys I'm also new to this and have found a 007p with yellow spring (no idea what this means) and its a 'JBS special edition'. What does this mean and is it okay to fit as normal?
