I have an 07 Arctic Cat 400. Non DVX. It’ll turn over and backfire through the carb. I have verified timing, tried in both positions. 180 out. Carb is clean but it’s an EBay special. But I have tried another carb (different from a 350 Rancher) with the exact same results. I have also verified valve lash, good fuel, good plug, compression is about 110. I’m about to my ends with this things?!? Any ideas?

      2009 Honda Rancher TRX420FA with shifting problems
      By Cj Winds
      I have a 2009 Honda Rancher TRX420FA with shifting problems.
      Usually it shifts ok when cold but after couple minutes it will stop shifting with no codes.
      The 1st shift clutch oil pressure when in first gear is 74psi. The 2nd shift clutch oil pressure when in second gear is 74psi.
      The 1st shift clutch oil pressure when in neutral is zero. The problem is when the tranny is in neutral the 2nd shift clutch pressure starts around 10-15psi and builds to 20psi. Is this normal?

      Здравствуйте, нужна помощь по ремонту багги Arctic Cat 700 EFI, пропала искра, датчик коленвала импульс есть, Самодиагностика показывает две ошибки AC99,AC96. все провода проверил на целостность, все датчики блоком определяются, не включается топливный насос. Провода от ECU до реле насоса и от реле до насоса исправны. Поставил подменный ECU, ничего не изменилось.

      2014-2023 Rancher 420 Plastics - New
      By 88classic
      I have (2) sets of brand new plastics available for Honda Rancher 420 2014-2023. These are genuine genuine OEM Honda plastics. One set is white and the other set is green. The boxes these are in are too big to ship.(Unless you want to pay for it. If so, lookup your own shipping rates from 17325 and box size is 58"x35"x18").  $400

      2006 Arctic Cat Utility transmission drive shaft replacement.
      By Shorty51
      Good morning, I am new to the forum. I'm 75 years old and love getting ATVs back to usable condition. I particularly like the 2006-2009 Arctic Cat 250 Utility. I currently own 6. The 2006 I am working on only has reverse and low gear. The "drive shaft" in the transmission is completely stripped where the high gear would mesh. Has anyone on here replaced the shaft. I'm told I have to split the case. I was hoping that someone on here could let me know how hard it will be. I already have it stripped down to where the shaft coming in from the clutch side is the only thing left. I was hoping I could just remove the driven clutch and drive it out from there. Directions say different. Any help would be greatly appreciated.
