Hello all. I’ve been riding motorcycles since I was 8 and have kept a few. Right now I pulled out a 1975 175 that was last registered in 2003 and has been non-opted since. It’s still street legal and I just got the rear rack off eBay. Also have a 1976 Yamaha 100 that is also street legal and non-opted. Up next a 1971 Yamaha 360 which all parts are there but has sat for a long time. My favorite is a 1971 Kawasaki KX 450 F12 and I think was the first of the green streak name. 
For now, it’s time for new friction plates on the 175 but the front wheel is froze. I wd-40’d everything but haven’t got very far with it.
I’ll be back with questions!

edit: I forgot my 1984 Suzuki LT125 quad runner and a 1996 Yamaha PW80 for my 8 year old grandson.

Hi & welcome from NZ. I guess you're in the US?. Enjoy your time here. Lots of good people to help with questions. We love photos haha but to show them they need to be posted via something like Imgur. I only manage to post a link via Google photos & I've  not got the knack of linking it live, but hitting the link works albeit annoying I guess. "71 360 has me sitting up & taking notice haha, love them. Last model before reed valve took over.
