So my neighbor had an old mini bike his son used to ride around on in the 90s, till the engine blew, I got it for free. I was planning on getting a 212 and being done, but in my usual online hunt, I found a 98 cr500 engine for 150$, ad says it runs, I can only imagine how impractically fun would this be. I can’t imagine the bike will stay on two wheels at any speed whatsoever, which isn’t really an issue for me but will the frame crack under the stress from that much power? I’m probably gonna pull the trigger on it regardless, but has anyone here had experience with something similar before?
