No, we don't use timers or lights, it's illegal street racing. But not in traffic like most people think. All you have to do is watch some of my youtube videos.
Some get there motors dynoed, but there are so many different motors, and combinations of parts there is to much left on the table. I build a lot of mild motors, usually only my own personal motors are pushed to the outer limits.

Minibike McCulloch MC9
When I was 8 my uncle and step dad built a mini bike with a McCulloch MC9 go kart engine for my birthday, we called it DEATH RIDER. It did about 55 mph. My mother stepped in and it went bye bye never to be seen again. I got another when I was twelve on my own but it was nothing special a manco with a 2hp briggs, no clutch, no brakes, and no throttle. I push started it and it went full throttle until I choked with my hand. Well now I'm 36 I just bought 2 doodle bugs for my kids and the fire has been re-lit. I will be rebuilding the DEATH RIDER very soon. I just found a MC9 and am going to make it happen as well as another that is even faster . I can't wait.

It's been said before but I believe should be repeated here. Power is not the only thing needed to go 60-70 MPH. A STABLE bike will be necessary. For instance: You might continually get away with a flat [not rounded in section] tire on the rear. You will be tempting fate if you run one on the front. Better have a powerful steering damper on the forks. Again, the rake/trail/frame length/tire diameter and a couple of other factors can make for a stable platform or one that is inherently unstable. High speed wobble [undampened oscillation] is unforgiving as hell. Really good chain and flywheel guards might be something to consider.
i had one on the rear and it was a bit squirrely when turning. i got used to it and it wasn't much of an issue for me (or my friends that were comfortable on mini bikes and had ridden them a bunch). now i'm working on running a rounded rear slick.
i also tried doing a flat slick on the front and that lasted for maybe 10 seconds of riding before i swapped it out for the old tire. it was damn near impossible to turn.

ut:i run the chen-shing 4.10/3.50-5 on my racing kart and they are the flat top slicks. i was having trouble with it not sliding and tipping up on its side. we put the tires on a brake lathe and rounded the edges over and took 5/8 of a second off my lap time.
most kart shops can do this its called cutting the tires. you can also use a grinder if you know what you are doing. you just have to keep the tire moving at all times.
briggs boy
Rounding the edges on a flat section tire, which is being used on the front of a two wheeler, would probably improve the terrorable handling by a little bit. But it'd still be good idea, if you are going to go really fast, to have your will filed with you lawyer, or better, put on a front tire with a cross section ment for a two wheeler.

there's stuff at my work that i could use to round off the tire if i wanted. i think i'm going to change to an 8" front wheel with a scooter type tire in the next few months so i'm not worried about it anymore.
i'm also putting on a 13x5-6 rear slick on once my wheel spacer gets finished. the guy said he'd have it tomorrow but i doubt he will. he's said it will be done at least 4 times now.
