i HAVE A 1982 SUZUKI DT85 THAT WAS SITTING ABOUT 5 YEARS. THE ENGINE HAD LOW HOURS FROM THE PREVIOUS OWNER WHO DIDN'T RUN IT MUCH. mY PROBLEM IS THE ENGINE IDLES FINE AND REVS UP IN REVERSE BUT IN FORWARD IT BOGGS AT ONE QUARTER THROTTLE AND KILLS. i'VE REPLACED THE PLUGS AND SPRAYED THE CARBS AND VENTURAS WITH GUMOUT. TOOK IT OUT TODAY AND STILL THE SAME PROBLEM. CHECKED THE OILING SYSTEM AND EVERYTHING LOOKS OK.

Champion,<br /> If the motor was stored a long time like that,I would look closer at the carbs.Try removing the bottom(bowls) on carbs.Make sure floats are going up/down easily.Make sure the pin(attached to float) is clean,etc.Check the pin seat for gunk.Do this to each carb one at a time.<br />Removal of carbs and a thorough cleaning inside may be necessary.Good luck. ;)Note:If you remove the floats the needle valve(pin)may fall out.Take notice where things go if you don't have a manual(which I highly suggest) :)

Champion,<br />Welcome to the greatest boating board.<br /><br />I don't know much about Suzuki's, JB's the expert on them and hopefully he's still out fishing and will deal with your post soon.<br /><br />Sounds to me that you have a carb problem that may need a complete strip down to solve. Just spraying gumout into the ventures may not be enough to get the residue from 5 years of standing.<br />Pulling the carbs apart is not a difficult project if you take care and follow a few simple precautions.<br /><br />1. Buy the manual as it will give you photo's to follow, plus how to fine tune the carbs after you rebuild them.<br />2. If you have a digital, video or Polaroid camera, take photos of all the linkages and their position before you start.<br />3. Only pull one carb apart and re-assemble before starting on the next.<br />4. Any mixture/idle screws, count the number of turns in till they seat and keep a record before removing them to clean the seats and jets.<br /><br />Hope this helps and I'm sure you will get many more tips from the board.<br />Good luck,<br />Peter

Howdy, Champ.<br /><br />You need to troubleshoot.<br /><br />1. See what happens if you spray some fuel mix into the carbs when it is misbehaving. If it picks up and gives you full power for a few seconds you need to go through your fuel system and overhaul the carb that needs the spray..<br /><br />If the fuel does no good crank her up on the earmuffs and pull each plug wire, in turn. The cylinder that makes no difference in rpm is dead. Troubleshoot the ignition system.<br /><br />Don't pay any attention to how a 2 stroke idles or revs with no load on it. They sound great on one cylinder.<br /><br />Good luck. :)
