    Short version of this story:

    I ran a great Yamaha motor, won a Great Lakes race with it, won local races at Pitt Race, etc despite my lack of skill; then I quit racing to focus on my son.

    Had Sean Cook at Cook Racing Engines change it over to to a sportsman version with a brand new HDC-5A clutch and 3 rebuilt sportsman carbs. It was a complete rebuilt that looks amazing. It was over $1,400 to rebuild & ship once you factor in the carbs and new clutch.

    The bad is, after I sent it to him, I sold my business, make less now and so I still have an open invoice I would love to close for him. I still owe $619 on it, would like to send him $700 for his patience in dealing with me. While I know Yamaha prices have fallen, I would love to get $1,200 out of it, but make me an offer that would get Sean paid and I’ll listen. I refuse to take my kid racing until I pay it off and he is begging to go to New Castle next week. I have a motor mount and all for it and you can keep the shipping container and all.
