Afternoon folks
My son rides an SR125, 1992 model. He has owned it for about a year now and it seems relatively incident free, with the exception of the CDI Unit. I had to replace this unit about six months ago, after a lot of head scratching and testing of parts I bit the bullet and replaced the CDI. ..Problem solved!
A couple of weeks ago he started complaining the bike wasnt running right and had no power. I took it a run and sure enough the bike would struggle under load (the engine, not me). There was also an occasional clatter from the top end. Valve clearances and cam chain checked and adjusted. Plug, cap and lead replaced to no avail. He purchased another CDI from ebay and hey presto, the bike is running fine again, He says it has an occasional backfire, but apart from that its fine.
Anyway the questions are
1/ By replacing a 20 year old part with another 20 year old part, this is going to keep happening so... Doeas the newer CDIs work on the older model. I know the pin connections are different but if I just solder on new connections will it work?
2/ and if not, Is it possible to crack open these units and get them repaired from an electronics guy
Thanks for any help here
