Hello there.. Newbieeees here.. I'm jim and my wife is marilyn.. :thumbsup: We have what we know is a Cat Mini Bike, but what model ?? THe lack of chrome plated handle bars is throwing us off just a bit.. Yellow when new, scrub rear brake, front & rear fenders w/ an offset colored stripe, folding foot pegs and the seat was anchored securely down with 5 bolts.. The frame number if this helps is 843421 ?? Also, i will leave a close up of the handle bar decal.. Maybe someone will recognize which model by this decal ?? Original motor expired long ago.. Tecumseh must have been use on this frame fromthe other Cat mini bikes we've seen here on this forum.. Please take a look at some of these photos and maybe you can narrow down the model ?? Thanx in advance, Jim & Marilyn.. >> Medford, OR. <<
