UPDATED: Help with 04 Viper Engine Rebuild
Hi All,
I'm new to Yammy's but not to snowmobiling. I've been a Polaris guy all my life, but looking for something different.
I'm looking for a winter project and I have a chance to pickup an 04 Viper S for pretty cheap. The guy said it ran for about 20 mins with a bad oil pump while he was trying to diagnose the problem. He said the motor isn't seized but he heard bearing grinding. The rest of the sled is mint.
Now I've redone top-ends before, but never done any kind of crank work, etc on the bottom end. I know I'm looking at new bearings, probably new top-end, perhaps even a crank? The crank new from Yamaha is over $1000, and I know a 00 & up SRX crank will work, but what is the worst case scenario for the engine rebuild?
Like I said I want a project but not something I'm going to have to drop $2000 into.
Thanks in advance for your insight.
