Yeah both coil and lead have been replaced and now have tested a working CDI and the bike runs perfectly, problem is it's only borrowed so I'm going to have to buy myself one and the old one is very hard to find...

I've ruled out pretty much everything else, spent far too long and too much money getting pretty much every possible problem fixed like fuel filter, carb cleaning, tank cleaning, jet cleaning, new spark plug, new battery and regulator, in fact after it stalled the last time I tested the spark plug and the spark was intermittent so it's basically the only thing left to try... If I'd have known it would be so expensive to try and run this bike I would definitely have got another one but I've already spent so much and I'm aware a dodgy 125 is worth piss all to most potential buyers

Hi all, My bike has a faulty CDI unit which is causing total loss of power every time I go over any kind of bump so it needs replacing, but I've been looking around and I'm confused by models and dates. Mine is from 1995 so does this mean anything pre-2003 when the new shape was introduced will work? Also how likely is the new shape to work in my bike, is it specifically for post 2003 models, as the new one is much easier to obtain and much cheaper. Thanks!

Thanks guys I'll give it a listen. Also another problem I have is occasional lumpy throttle and sputtering at stable RPMS. I'm pretty sure I caused this a while back by running the reserve tank dry as I didn't realise that it was actually on reserve - I know, shoot me, ridiculous mistake - but I believe it pulled some dirt into the fuel system and into the carb, problem is I don't have the tools or the knowhow as it stands to be able to disassemble the carb and the jets to try to localise or fix the problem :-/ has anyone else had this same issue and know how long it takes just so I could get an idea of costs?

My SR has developed a noticeable rattle in the engine, but I'm a bit of a bike retard so I don't know what it actually is, does this sound like a crankshaft bearing? Only thing I know is its a long job to fix so another question is if I have a problem with the bottom end how long is it safe to keep riding?
