Just had a 85 BW 200 given to me. Not really sure what to do so I am asking for advice... The enginge is smoked, I can hear the rod knock just kicking it over. The charge coil is shot.... cdi might be junk as well. I did some searching and parts for these things seem to be kinda rare and or pricey. My question is, are they even worth the effort now? The few items I mentioned would cost about a grand to fix buying new stuff and rebuilding the engine... The bike itself is in suprisingly good shape for its age and I had one brand new way back in the day.I really did like the bike. Are there any other engines that could be swapped in? I thought about a blaster engine...... Any ideas?
