Replace motor?

[wingr1800]

I have a thread a few lines down about problems, but no regrets. I now now know I blew a rod (correct terminology?). The dealership is working on something for me. It's an '09 Vector LTX with between
5-6K miles, and very good condition. I'm curious if anyone here has heard of or replaced a motor. I really like the sled, but I guess I don't want to get way over my head on this. The dealership I go to is a very well known Yamaha dealership and does a lot of performance work also. I have dealt with them for quite some time and I like, as well as trust, everyone that works there.

Went to look at sled this morning. The hole is on the bottom of block, middle cylinder. The hole is a little smaller than a silver dollar.

check with barn of parts or one of the other sled scrappers on here about how much a motor will be for it.

Curious why did the engine blow with that low of miles?

Have seen quite a few over my 10 years of stripping Yamaha sleds. Granted I am in the parts business, so people call me when they have one with a bad motor. In overall scheme its not common, and I think it comes down to a mfg defect such as improper tolerance. By no means are the motors prone to this kind of failure.

I have (2) of these motors available if you opt to fix yours.

I would NOT fix the engine. Simply look for a smashed or junk sled or buy a used stock engine from someone, like hibshman for example.
It is VERY rare for these engines to fail. One thing I have seen on these engines that are carbureted is fuel leaks by the needle valve for some reason filling a cylinder with fuel, then the next time the engine is attempted to start, it hydralocks and damages the rod.
