I had an RD350 (believe it was a '74 - purple) that came in a box from a guy for $50. Put it back together but was too into dirt bikes at the time and gave it to a friend. I do still have the College Station Yamaha metal license plate frame that was on it. My first real motorcycle was a '71 Yamaha HS1 90 cc twin cylinder two stroke street bike. Traded it for a basket case Bultaco that never ran right. Don't have any of those any more, but I do have:
Here's a picture of my 2001 CR500R engine in a 2002 CRF450R frame. This was just after I finished a ground up refresh. It now has a few rides on it.
One of my mostly stock 2001 CR500Rs. This photo is an older picture and the bike isn't as pristine as it looked then; it does get ridden.
And the other 2001 CR500R. It's apart right now. Bought it and planned to make a woods bike out of it. But, it is now waiting on a 2008 CRF450R aluminum frame that's being modified for the engine:
In '87, I decided to get into motocross with a brand new '87 CR500R. I don't have any pictures of just the bike, but this is me racing the amateur MX race in the Astrodome back in '89. I fully admit I had no business there on that track but I did somehow end up with a 4th place out of 7 riders. I've been trying to find time to restore this one. I have it mostly broke down, but the swing arm shaft is stuck and I'm trying to figure out how to get it out. Heat, penetrating oil, and even a 12 ton press won't move it.
