I have a scrambler 400 and it will not go forward. Reverse works fine but when i shift it into forward it just sits there, it just happened the other day, up until then it ran fine. Any ideas where to start trouble shooting or what is wrong?

Can you hear it click into gear and are your shift lights working? I have the 98 xplorer 400L but i am assuming they are a lot alike. Mine was messing up and I had to adjust the shift rods from the gear shift to the transmission. Worked perfect after adjustment. I would check there first.

Is there any grinding when you try to shift into forward. I have that problem on my polaris and I had to fix the gears that had worn down. If there is no grinding and you are pushing into gear hard then something might be loose in the shifter.

check your shifting linkage...i have a similar problem with my 94 polaris... if you do hear a grinding when you go into reverse or any gear and you need to force it you need to lower you rpms...there is a screw on your carb that allows you to do that

I agree that you need to check your linkage, if you hear it going into gear with a "click" then it is deeper than linkage and you need to check your gears in your tranny. If you are not confident in your skills then I would recomend taking it to your local shop because the Polaris tranny can sometimes be diffucult if you are unsure what is wrong with it.

The linkage might need readjusted. Check out mine at atvwheelin.com there are other tech tips there too.:wink:

Its all a guess till you crack it open...Dog gear or silent chain would be my guess. if it grinds most likley the chain if your hear nothing broken dog gear..still just a guess.

Good luck PolarisATVrepair.com

      Just picked up an 84 LT185 ATV, I understand there was an accessory add  on that gave it electric start, anyone have any info about that kit?

      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.
