Thanks for your help/ advice, what size jets would you be running in it then? The need jet is still the same as the spec says and is on the correct clip position, thanks

Hi, I'm new to this forum tonight, after struggling for a few days I've decided to join and ask for help. I've got a DT 125 LC MK1 When I first brought this bike a month ago as a project, it would start fine but wouldn't rev up past 1/2-3/4 throttle and seemed lacking in power, I stripped the carb down gave it a good clean out and see that the main jet was a 140 and the pilot was a 25. I ordered new jets for it so it's now got a 20 as a pilot and a 100 as main, I chose 100 over a 80 as it has a sports exhaust on it, updated reed valves and a aftermarket filter. I've been and fitted the carb on the bike tonight. It was a struggle to get it to start and now it will only run on choke, as soon as you push the choke button in it gradually dies and you cannot rev atall to stop it. It still doesn't rev up properly and it's very smokey now, leaves a cloud behind when you ride it. Can someone please shed some light on this before I throw it in the scrap ? Thanks Tony
