85 polaris trailboss 250 firing trouble

Recommended Posts

so I seem to have some trouble getting my old 85 trail boss to put out a spark. when I first got it it fired just fine but had no compression. After I rebuilt the top end and tried to start it there was no spark so I got on the internet and ordered a used coil that came off of the same bike and it worked and ran good for about two weeks. When I really got the engine going good it would lose power and start to bog down but would quickly recover after a few seconds. Then one day it wouldn't starts and I found that it was not firing at all. Now I`ve put a brand new coil and there is still no spark. Everyone I know seems to think its the cdi box. However when I search on the internet everything points to the stator. Is there a way of testing either one?

      I have a 2008 loncin desert storm that wont stay running.
      When it ran it ran rough and backfired a lot.
      Now it will only start with throttle and there's a lot of unburned fuel (white smoke), there's also compression comming out the airbox. Is it the carburetor that is broken?

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      Does anyone have a redcat 250 or falcon 250cc that they can share where the two vacuum lines on the carburetor that you run antifreeze through I honestly have no idea where the lines are suppose to go to circulate the antifreeze. 
       
      Any help is greatly appreciated.

      Recently I noticed gas leaking from under the gas tank on my 2005 250 2x4. As I looked closer it appears to be leaking from the shut off valve under the tank. It's the valve with the handle that can be turned to open, close or reserve. Can this part be replaced? Thank you.

      Just bought (Tue. evening) an '89 Suzuki 250 4wd that has been sitting out the last 5 yrs. It's complete, including the shift knobs, battery cover, and headlights. It has the optional cooling fan on it (probly stuck - didn't check), and the engine isn't locked up. Plastic looks good and isnt cracked. Racks aren't bent up. Shift lever works, the foot brake moves (needs oil - have to pull it up by hand), and there's black oil and no water in the engine sight glass. Guy was asking $125 and gladly took $100 for it. Anxious to get started on bringing it back to life. Been wanting one of these for years. As soon as I can get to it (working on a junky "Jackel" right now - Chinese Yamaha Timberwolf). I'm going to pull the tank off it and clean it, clean & possibly rebuild carb, put in new plug, and a battery, then see what happens. If nothing, will keep going until it runs. Feel free to respond if you want to, I'm mainly just excited and wanted to tell somebody.

      I just bought two 1985 TRX250's from my father-in-law. One runs great, the other not so much. The one is having issues with the shifter. The shifter seems to be resting lower than normal. When I press the shifter downward, it just pops back up. Any thougjts as to what the issue might be?
