the video is pretty cool. i wonder what modification is needed on that year of cr250 cases ? really i havent done a ton of research but i was under the impression a puma would bolt directly to the older cr250 cases from the mid 80's. and since them bikes can be found real cheap, thats what i was thinking of using. but hell if that cylinder can also be easily fit to the mid 90'[s cases then maybe that a better idea. the PV is cool but i was thinking nonPV since it would just be a drag racer
