Hi Mark,
Here are some pictures and a link to the video of Lucas' recent wins! (click picture for link)

Thanks for all your help again

Lucas has won 2 races at Homestead Karting with the help of your B.R.E. blueprint engine! Not only did he win both races by quite a lead, but the engine passed tech without a hitch! This is also Lucas' first season participating in the FCKS Series in Florida. He placed third in the last race in Orlando, again with the B.R.E. engine!

Your customer service is incredible ... Thank you for all your help!
