Zen..........to be peaceful and calm
When restoring, building or repairing a motorcycle it really helps to be peaceful and calm. Step back for a minute and breath deeply. Look at what you are building and grom on it for a few. With patience you won't wreck that bolt, carb or whatever you're working on.
When any motorcycle was created at the factory the engineer had to step back and feel what he or she was building. They didn't always get it right and sometimes they got it right but the bean counters got involved. Afterall they had to make a profit.
If it's your machine that you are working on it doesn't hurt to take a few liberties. You may want to really breath deep before you take that torch to a Crocker frame! Somethings can't be reversed.
Above all make it an enjoyable experience.. you may go the the national Vincent rally and be the one who stands out. Afterall, it's not difficult to make a cookie cutter restoration if you have deep enough pockets. Have fun or drive a Toyota!
