I just picked up a CB250 today 2nd hand & took it for a spin. I took it up the motorway & top speed is 45MPH, I’ve had feckin mopeds faster.

Any ideas what could be causing it or what I can do to see what’s wrong.
I’m no mechanic but I’ve tools here & can do the basic stuff like servicing it.

I’m hoping it’s something simple :rolleyes2:
