I ran Cobra`s at Daytona last month and here`s what happened. I`m one month away from 70 years old and have never ran Daytona so I wanted to scratch it off my bucket list. My kart is a completely rebuilt 1997 Trick Typhoon with a rebuilt and newly blueprinted TS Racing KT 100, TSOW pipe with 9 5/8 flex, Bully 3 disc set at .250. I ran with the Unlimited Allstars. The first practice at Daytona were the first laps I have run in 12 years. I ran a 6.00 tire on the RF because Trick told me that is the tire they used when the kart was designed and it handled great compared to the 8.00 I had run in the past. Other tires were LF 4.50 LR 6.00 all on 6" wide wheels and RR 8.00 on a 8.78 wide wheel.
Day 1 First practice - New Cobra`s punching 52 no prep air at LF 6 RF 7 LR 5 RR 7, spun first two turns I hit.
Lowered air to LF 2 RF 4 LR 3 RR 4 for qualifying and prepped with equal parts of Track Tac GKI Blue, BTGP Red, Black Sand and a little Wintergreen.
Qualifying time was 17.81 in day time, cloudy upper 60`s temp.
Race time was about 11:30 pm with temps around 55, my fast time was 18.46.
Day 2 Prep, tire pressures and weather about same as above.
Two minor adjustments I had to make were RF tire moved out, rubbing tie rod and RR moved out, rubbing frame.
Qualifying time was 17.57.
Race time was 18.22 after 6 laps, Unlimiteds were running 3 - 4 seconds faster and I wanted to get out of their way.
Previous years qualifying times when Yamaha`s ran were; 2013 - 18.25, 2014 - 17.23 and 2015 - 17.06.
I feel I did pretty good for an old man and an old kart.
I had a set of new untouched Vegas yellows but didn`t want to use them.
I wanted to give the Cobra`s a good test and see how they would hold up.
In my opinion the held up very well and showed almost no wear on Daytona`s rough Limestone track.
A week after Daytona my Cobra`s were punching 46 - 48.
