My story with my Perana. I don't drive it but I start it and move it. Last time I drove it the clip that holds the brake and clutch fork in the peddle box came off and the bar fell out of the peddle box.
I was just abou to go down the hills to Wisemans Ferry with no brakes and no clutch. Lucky I realised something was wrong.
In my opinion these are the ultimate as performance wise nothing stacks up as stock.
I can't have two but anyone who buys it should respect it. Hopefully
