I have called Honda here in Nova Scotia, and I have researched for a few days, but I can't find out what year the motor I have bought is...I found this on the block. L250e L100633 It is "supposed" to be a late 80's XR 250. But, I'm afraid it might be an older XL 250 for some reason. (big heavy chrome kickstarter). My 4 valve motor blew in my 84 XR 200 and this was supposed to be a project replacement engine. Anyone have any input? I don't have any access to the Frame or VIN the motor came from...long story.
