Might be easier just to buy one of the Dawes devices ? Cheap and can get it spot on 1 bar. I do have one of those restrictor pipes in my glovebox I think so may be able to check if no one knows
Now Shagging sheep on the cheap
You wont find one that's for keeps
Spend the money, find a honey
'Shit' think I need to sell my Sunny!
But woman cant replace a sheep
Oh I wish that for the peace!
But I really cant find my honey
The only one I would give my money
Is one with a great big fleece
And then I would be at peace...
