Help! I grew up with bikes (TY80 -> RM80T (awesome bike at the time!) -> RM100T -> GSX250 -> CX500), trouble is, it's been nearly 20years since I owned one and I now want to get back into it. I am thinking cheap off-road and mid-eighties which gets me something that works and I can fix 'cause it's what I grew up with. Only real issue I have is the electronics of these old beasts. A quick check of a few online parts places shows that (for example) the CDI for a 1981 IT 465 is discontinued. How would I go about resolving this? Can units from other bikes be modded to work? Are there aftermarket alternatives? etc. etc. Thanks, Brian
