As an update....
I managed to get a good front master brake cylinder the other day.. fitted it yesterday, and the brakes are now working well enough to pass the test..
Sorted out the airbox, and filter, and she's just about ready for testing.. just need to get the Hagon shocks fitted I got a while ago, and sort out the rear tyre, as it's not on the rim right..
Hopefully next week it may be roadworthy... can't wait to have a burn on her..
