It very well could be, I actually never got that far. Before I bought mine, well actually let me back up. I have a suzuki twin peaks. Never heard of them before I saw it for sale. It is the same as the kawasaki prairie 650, or Brute force SRA.
I was looking for a non running project. I came across this and started reading anything I could find. I assumed it needed a complete rebuild. As cheap as it was. In my reading I found guys that have 45k miles, up to 80k miles on the original engines. It was shocking. These guys were putting a hundred miles a day on them for ranch use. Never did more than normal maintenance.
Then the flip side was guys that water log them, or abuse them and tear them up pretty bad in 2k miles.
Then of course you have the hot cams and big bore kits with guys doing heavy mods.
So I was prepared for the worst when I bought it. I think mine has 5k miles on it and I wanted to build it to make it as dependable as possible.
Got it home, started tearing it apart. Did the basic diagnostics on it. Couldn't really find anything wrong with it other than the oil smelled like gasoline.
I rebuilt the carbs, drained the oil a couple times. It fired up and purred like a kitten. I did all the basic maintenance, it Needed a clutch, I put a used one on it. Really haven't done anything else mechanically to it.
Granted it may not be running 100 %.Might be down on power a little from the factory but It still have way more power than anything I need it for. the tires are old and hard, but if I get traction it will pull the front end off the ground. It will run 65mph pretty easily, Probably faster but I don't have the guts.
I keep waiting for something else to fail, fuel pump, CDI box, something. But it just keeps going.
Maybe I just got lucky but it is the nicest riding, handling, running machine I have ever been on. The only complaint I have is with difficult obstacles or steep climbs. It wants to pull the front end off the ground with light throttle. That is scary when you are already afraid of it rolling over backwards on you.
