Dear Ralph: I’ve been riding a ’97 Arctic Cat ZR 580 EFI for a while now since frying pistons in another sled, and it has a few problems. I’m not sure if this is a mechanical or electrical problem or what, but two dealers have had it on the... Read more

Dear Ralph: I have a ‘99 Ski-Doo Summit X 670 with stock clutching and I would like to know what helix and spring to purchase with a Team roller secondary. Should I change anything in the primary? It has a two inch 136 Challenger track. The sled is used... Read more

Dear Ralph: A friend of mine has a ‘97 Polaris XLT Special that falls flat on it’s face when held wide open. At 3/4 throttle it runs great; 70 mph at 7800rpm’s. But when you open it up all the way it dogs down to 6800rpm’s & 45mph! I... Read more

Dear Ralph: I have a 2002 Polaris RMK 800 with the 151” track. At the end of last season I changed out the stock driven clutch for a Team Rapid Reaction Driven. The difference is incredible, anyone that rides a sled in the mountains should get this totally affordable... Read more

Dear Ralph: I have a 2003 Arctic Cat 900 Mountain Cat and have a problem with the throttle sticking. I’ve checked the cables and the splitter box, but they seem to be fine. The only thing I can think of is that the carbs are freezing up. Christopher Peacock... Read more

Dear Ralph: Is there a problem with the cranks on the 00-01-02 800 Polaris? I know of five that have broken the P.T.O. side after 3000 – 5000 miles. Also, does Polaris know about this and did they fix it for 03-04? Would I be better off to put... Read more
