Sold my my bike (not through this site though) I think I have managed to correctly mark as ‘completed’ in the Classified section

I guess you have done the basics Lolo, but practically if you have, you won’t have a weird starting problem, as it’s not magic! Have you paid any attention to the carb/mixture settings? Does it run particularly weak or rich? Plug condition/gap age of coil ht lead condition etc etc Good luck 🤞

Thanks for raising the profile of the Classifieds guys, it has prompted me to list my SR125 on this site, as well as E-Bay 😀

Yamamat, let me know how it goes, I also recently came across them and am tempted. I will be selling my SR soon, but rather it was running perfectly before I sell it, and this looks to be an interesting option

In case it helps someone, you can get them repaired , but it’s expensive! https://www.carmoelectronics.co.uk/index.php?main_page=index&cPath=493_4686_2129_2445

Adding pictures is easy, on reply go to add files and follow the steps 😀

No progress on CDI unit, have had a couple of used ones through EBay which haven’t generated a spark at all. On the plus side Theory Test Passed and Module 1 booked for late June 😎

Just putting this back out there again. I’ve had 2 used ones from eBay which have resulted in no spark at all, so I’m back on the existing one which gives limited performance

I have both a car and a bike with no fuel gauge. You quickly become good at working out how many miles you will do on a tank and adjusting it conservatively based on driving / riding style !

If you can’t fix it with a hammer then it must be electrical! yes, previous owner did rather a hacksaw job on the frame, I can see what he was aiming for but craftsman he was not! current issue I have is CDI Unit. One unit and the bike will only tickle 50mph, the other it runs like a dream 60mph plus for about 12 miles, then misfires and conks out. I’m trying to find out if there is a modern workaround / new unit that can be made to work

I see you have no relied Clive, did you make any progress? *replies

Riding for about a year, owner of a fairly rough 1991 model and enjoying the trials of running a 30 year old small bike 😀

I have 2 CDI units for my Sr125, on the one unit the bike runs reliably but maxes out at 50mph and has poor acceleration. On the other Unit I will hit 60mph easily and acceleration is good, but after 12 miles misfires and becomes unrideable So, both units I believe are at fault. For the early unit 5HO-MO very few are available. For the later unit there are more on eBay. Q1 has anyone used a later unit on an earlier bike? Q2 has anyone found an alternative new manufactured CDI that will work well. thanks in advance for any replies Tom
