Bad Fuel Pump

Well I bought my 570 from Columbus TX. It really seemed to be a good machine until I had issues with it sputtering and losing power. I bought it so I could drag and work on my baseball field, so it has hardly any hours. Well the reason for it not having many hours on it is because it would not run and would just idle and then die. I took it in and was told it was a bad fuel pump. So they replaced it. About 3 months later, the same issue occurred and they had to put a new fuel pump. I asked them what else I could do to make sure it did t happen again, so I started putting premium gas and an additive to make sure it didn’t happen again. Well it happened once again. They once again blamed it on being bad gas and not running the machine a lot, but yet when I talked to the Technicians, they said the gas was good and Polaris has known about their fuel pump issues. They said that the fuel filter is on the inside of the fuel pump and cannot be replaced without replacing the whole thing. The techs proceeded to tell me that it is a bad design and that they continuously see these fuel pump issues. I then took it to another dealership this last time today and picked it up. As I talked to the front desk people, they said there was another gentleman who just came in with the same issue on a 450. They said if it were them, they would sell the machine and try to purchase something else without known issues. Is everyone having problems with the sportsman 570s? If so, they should recall them.

I need to know options on clutch rebuild kit. I just replaced belt and when in high gear it makes a lound rattaling noise but does not do it in reverse or low. Anybody have any good suggestions.

No fluid in Gearbox?

So I recently picked up a 2013 Renegade 1000 used. I got a pretty good deal on it but its a bit of a project. Went to change fluids and the oil was surprisingly cleanish and free from much metal on the drain plug magnet.

Went to drain the gearbox and was surprised to find that no fluid drained, I looked at the drain plug and it had what appeared to be heavy grease on it. I added a few ounces of Royal Purple into the filler and those few ounces flowed back out the drain plug so its not clogged. It appears the gearbox was completely empty, the fluid solidified, or the fluid was replaced with grease.

I tried to search about this but did not turn up anything. The bike has 200 hours on it and ran and drove fine without any major gearbox noise prior to this. Should I just add fluid and go about driving it or is there anything else I can do to prevent further damage at this point?

New here so any advise helps.

Old 7 digit VIN

Anybody know how to decipher the old 7 digit VINs. I Found an 88 trailboss 250 for sale, but the frame was painted and I was only able to make out 5 of the 7 digits. I think I missed the first digit is which I determined is probably a 1. I'm at a lost as to what other digit I missed and what number it could be.

Thanks,
Mike
