First off I could say it's perfect-amazing-over the top but I can't since I don't think there are words in our language that could ever convey or express the quality or what you do-I'm more than completely blown away-w0w!!!.What is the rear tire you're using? It looks kinda like the tire from my revell triumph drag bike that I've had for about 30 years that I've never started.After seeing this I think it's time to start rockin on it.Thanks for the inspiration.
