Frequently Asked Questions - ST 90 Ripper (2018) Timbersled
What type of fuel should I use for my Timbersled ST 90 Ripper?
Use high-octane unleaded gasoline with at least 91 octane. Avoid ethanol blends over 10% to prevent fuel system damage.
How often should I check the track tension?
Check track tension every 500 miles or before each ride. Proper tension ensures optimal performance and prevents track damage.
What oil is recommended for the engine?
Use a synthetic 2-stroke oil specifically designed for snowmobiles. Mix at a ratio of 40:1 if pre-mixing.
How do I store my snowmobile for the summer?
Clean the sled, stabilize the fuel, fog the engine, grease the suspension, and cover it in a dry place. Remove the battery and store it on a tender.
Why does my snowmobile not start?
Common causes include a dead battery, old fuel, or a blocked fuel line. Check the spark plug and ensure the kill switch is not engaged.
How do I adjust the ski stance?
Loosen the bolts on the spindle and move the skis to the desired width. Tighten to factory torque specifications to avoid steering issues.
What is the break-in period?
The first 500 miles are crucial. Avoid full throttle for extended periods and vary speeds to allow the engine to seat the rings.
How do I check the coolant level?
Locate the coolant reservoir in the engine compartment. Ensure the level is between MIN and MAX marks when cold, and top up with the recommended 50/50 coolant mix.
Can I ride on hard-packed snow?
Yes, but it is recommended to use carbide runners for steering and maintain a slower, controlled speed to preserve track life.
Where can I find replacement parts?
Use genuine Timbersled parts from an authorized dealer. Consult the parts diagram in the manual or online for correct part numbers.
