I wasn't going to speak on this matter, but I have nothing better to do. Dave, DO NOT PAY A DIME for the services "performed".! I realize they are acting a if to be all helpful, since you talked to the owner. You should have never had to talk to the owner! A motor can be rebuilt in a day, 3 days if you have to order parts. a clutch that was working, will work, unless installed WRONG! Call an attorney and find out about the lemon law. Another option is the right to recind. If it had something wrong within 3 days you can use that. If they say you owe them anything, mention what said lawyer tells you. They should be buying you gear, beer, and taking it out of your rear(with vasoline).
