If there is already a thread on this subject for the DF 250 bobber that is not 8000 replies long please tell me and I will stop. If not, I thought it would be useful and handy to have a thread that dealt with sometimes hard to find parts such as something as small as a stock replacement turn signal lens that I can absolutely NOT find, 520 chain sprockets (front and rear) and 428 conversion sources, piston and cylinder kits that will add displacement and bolt right on or with minor mods bolt on. Info like this. Thank you for any info in advance that will make owning and repairing / rebuilding a DF 250 RTB or a Heist motor if the exact same? a little if not a lot easier.
