  If the handling of your Arctic Cat Offroad Vehicle feels too heavy or stiff, it could be due to incorrect front wheel alignment (adjust the alignment). Other potential causes include inadequate lubrication (lubricate the appropriate components), incorrect tire inflation pressure (adjust the pressure), seizing tie rod ends (replace the tie rod ends), or seizing linkage connections (repair or replace the connections).

What to do if my Arctic Cat DVX 400 2004 Offroad Vehicle engine will not start or is hard to start (Compression too low)?
- C
  caleb16Aug 25, 2025
  If your Arctic Cat Offroad Vehicle engine is hard to start and the compression is too low, possible causes include valve clearance out of adjustment (adjust the clearance), worn valve guides (repair or replace the guides), or mistimed valves (time the camshafts). Other potential issues are excessively worn piston rings (replace the rings), a worn cylinder bore (replace or rebore the cylinder), or a poorly seating spark plug (tighten the plug). If the starter motor cranks too slowly or doesn't turn, consult the 'Electrical' section.
