checked the coil and Pickup coil wiring with multi meter all ok.Fitted a new O ring to idle screw that didnt look to healthy, there's no O ring fitted to the airscrew dosnt show it on the parts PDF.Fuel level was checked and that was ok aswell.
The 125 carb is the same size only the jets and needles are different.
I got it running on idle today at 1300rpm and was ok,going to have another look at the throttle cable in case its sticking was a bit slow in dropping its revs to 1300 but it still cut out though after blipping the throttle. >
I got a timing light and a ColourTune so going to fit that see what colour it shows the mixture, that should give me a indication of whats happening mixture wise. If i open the choke the bike looses revs like its going to stall so thats normal anyhow with hot engine.
Im getting there slowly
And to make things worse spotted my ex Yamaha TT350 i sold 5years ago, in Melksham the other day
