i am really sorry to hear that happend man..
the question is..
--do you really like that sled...if you were to fix it, would you be willing to ride it for at least 2 more seasons or keep it as long as possible
well, if it were me...this is what i would do..
call IndyDan..
ask if he can hook you up with the TMI/TMII/TMIII crank and some crank cases...he will line bore the cases to fit the crank perfectly..then you will a great stout crank with warranty by the best in the business..
I have no idea what his prices are right now...but you need to get ahold of him asap before he starts building other sledders engines in the summer!!!!!!!!!!!!!!
he can also get you a TOP END kit for a good deal as well
that alone is WAY better then your quote..
here are some cylinders on ebay, 2 used and 1 brandnew..
