Dealer told me the Yamaha rep back in the day told them to do an upper rebuild on the 700 2 stroke Vipers at 2000 miles as they had a weak spot and it would take the lower end out as well. Any of you heard of this? Mine has 1800 miles and runs fine
 

3800 on mine and no issues so far. I'm also not a trail rider that is in the mid-range a lot, and therefore haven't raised my needles.
 
I snow checked a new 02 viper and in the fall of 04 I bought a new sled and sold the viper with just shy of 8000 miles and the engine was never apart the only problem i had was a cracked y pipe
