Hey!!
welcome from a chilly Yorkshire UK.
I'm newer than you haha and if you think your TR1 is rattley you should see my CX500 shed. It will make you feel a whole lot better.
When I get it home on Saturday I'll post a pic. It's the bike of my childhood, on my wall when I was 16 riding a Suzuki X1 thinking ... One day!
Saturday is ' The Day'
It will be my project for the forseeable but will owe me nothing so what the hell.
your Tr1 looks great, I nearly bought a TRX and still might..
Keep flying the flag.
