Hey everyone I'm new here today. My boyfriend had a 92 Nsr 250, that was until he accidentally wrote it off. Now it's been sitting under the house for 3 years and I'm thinking there still may be money to be made on it. It's a sore spot for him so he won't talk to me about it. I wanted to know if anyone could inform me on how you find out if it's MC-21. MC-18?? I've been doing as much research as I can and havn't come up with much - I'm alot better with cars!!! So does anyone know what the tank would be worth - it's still in perfect condition - surprisingly enough!! And I've still got the gauges and a few other things - any sort of help would really be appreciated. Thanks guys
