Well I picked up a 2007 800r about a month ago. The guy I bought it from said that the motor had been rebuilt to deal with the 07 issues. Took it out today and went 4km and the motor seized, coolant pissing everywhere. Haven't torn the engine down to see the extent of the damage, but I think I am going to install a new shortblock. Will the 08 shortblock fit? Who has the best prices?
