78.6 MPH??? How slow, tune!!

I have a 1986 RD125LC. It was bored out to around 140cc, straight through exhaust on it, aftermarket airfilter, and a new plug.
If the powervalve was open, it would sit at 85mph, and I had 95 out of it, but it wasnt happy (And neither was I, It winds a lot)
They are a great little bike. Mine was knackered when I got it, and needed loads of work to get it throught the MOT. I blew it up a couple of months back, but have just had it re-honed and a new 58mm piston in it, which should make it around 155cc. Want to get her back on the road and run in, so I can see if it is any faster!!!
