Hey bud that’s a huge carb for a 125 you’d be trying to jet it forever
Your better off going with a smaller carb
Like 22-26mm mikuni

Have a look at a pwk 26mm or smaller 22mm any of the cheap carbs will do but have a look a molkt 26mm
That size would be the biggest you’d go on a 125 ive used several molkt carbs over the years there a good basic carb and will do the job for ya just my opinion mate

I hear you there see my goal is to get it to be able to run about 80 miles an hour so I can stay on the freeway because I try to avoid all these are highways right now when I'm going to and from work because I can't get it to get over 70 miles an hour I barely reach 70 and that's pushing it everything I got and I don't like being able to you know get up and get out the way if I need to with crazy people drive it on the expressway but that's my goal to get my razkull running 80 to 85 miles an hour

Your next option would be a big bore kit for your 125 or look at going to a bigger engine like a 140cc and would be a lot easier to comfortably get it to 80 mph and you’d have a better chance of jetting your pe28 have a look on tbolt they’ve got eclectic start yx140 engines send them an email there great people to deal with
