I have no idea, but I will offer this I would base the amount on parts being available since it is in a non-running condition . From what I understand kohler parts are hard to find for the I assume flat twin and what is available is pricey. You have to also think about what you will find when you do get it started, that is unseen now. A repower I would think is 2 k at least anyway. If they want that much have them get it to run so surprises for you are kept at a minimum. good luck
