I'm looking at one that has aftermarket a-arms and Elka stage 4's all around it looks like a really nice bike in the pictures, but the guy took it out this past weekend and said now its hard to turn it over. He's not sure if its just a crank bearing or if its a rod bearing, it ran fine up till then he drove it all weekend. Anyway it's still a pretty good deal cause he said he will sell it as is if I want, only thing is I'm not sure if I want to get I to it. That's why I was wondering how these things are for cranks and rods and pistons? Anyone have any ideas what it might be. It does still turn over just not fast. I am going to see it in person on Saturday.
