I've restored my son's '81 PK Ripper looptail
He used to race it (I was his pit man) at Waterford Oaks in Waterford, Mi.
Up here, BMX's are not too popular except with the grade school/middle school kids that like to bash. No tracks, no BMX's is the way it goes.
Over the years we have been approached many times to sell that Looptail for 400.00 and more. Not too many out there that are not wrecked with cracks or missing Landing Gear fork.
