Q: Why does my valve clearance get tighter?

A: Your valve or valves are titanium with a thin oxide coating on them. once the coating is worn thru it has no surface wear abrasion and will slowly sink into the head, tightening up the clearance.

Q: My bike has been sitting for months, fork seals leaking on first ride.

A: The seals and wipers have conformed to the profile of the forks at full extension. When compressed, they travel over several different profiles, each with their different high and low spots, allowing oil to weep out. The problem is magnified when cold weather storage is factored in. Warm weather riding may soften up the seals so they will seal again. Or you have a big ding in the tube you did not know about, and it is chewing your seal up.

Q: How do I properly clean my air filter?

A: Your air filter is a very important part to maintain. A dirty filter will allow dirt to enter your motor and cause premature engine wear. To clean your filter remove it from the airbox carefully. Try not to let dirt fall down into the carb. Clean your filter in solvent first, this will remove the oil. Then you wash it in warm water with dishsoap. We recommend Dawn. Clean throughly do not wring out it will rip your filter. Hang to dry completely before you apply your filter oil. Make sure you use plenty of filter oil we recommend a foam filter oil. Wipe out your airbox before reinstalling your clean filter. Do these simple steps before you ride your bike each time.

Q: Riding with leaking fork/shock seal.

A: The longer you ride with leaking seals increases the possibility of damaging the fork tubes and shock shaft. Fork sliders without lubrication will start scraping off the anodizing from the inside of the stanchion, then the tube itself. Shocks without oil are worse. The outside diameter of the seal head will chew through the anodizing/shock body. The inner diameter will wear through the chrome on the shaft. It is cheaper, easier, and faster to have your seals replaced rather than replacing your forks and shock.

Q: How often should I change my shock oil?

A: The rear shock on your dirtbike is subject to much higher temperatures than the forks. We would recommend a minimum of 2 oil changes per year unless you have a leaking shaft seal, then it should be serviced as soon as possible.

Q: What can be done to make my titanium valves last longer?

A: The valve seats in your head are a hard steel material. We can install nickel bronze seats which is much more forgiving when using titanium valves. It also disperses heat much better.

Q: How often should I change my 2 stroke transmission oil?

A: Due to the capacity it is recommended that you change it frequently. Every couple of rides is best. You should always use a racing oil for wet clutch applications.

Q: How often should I change my 4 stroke engine oil?

A: You can not change oil enough in any dirt bike. We recommend that you change it at least every two rides.

Q: Why is my bike getting harder to kick start? It will jump start but I can not kick start it. What is the problem?

A: When your bike gets harder to start it is time to check your valves. As the valve clearances tighten it will be harder to start because the cylinder is not able to make pressure at kickstart rpm.

Q: What is the proper method to wash my bike?

A: Use a soap that is designed for cold water use. If you are using a pressure washer try to avoid prolonged contact on bearing seals. If you are washing your bike between races it is not a bad idea to put a plastic bag over the air filter. When washing your bike this is a good time to look for loose bolts or worn parts that you might not always notice. When your finished washing it is a good idea to start your bike and let it warm up to help stop condensation in some areas that are not visible. On 2 stroke bikes remove the ignition cover and let it dry if there is a sign of moisture.

Q: My forks bottom out on big jumps. Should I get stiffer springs?

A: If you weigh more than 200lbs then yes you are out of range of the standard springs. Before buying stiffer springs try adding oil in 10cc increments. Remember spring pre-load mainly affects the 1st 1/3 of the travel. Spring rate mainly affects the second third of travel and oil volume affects the last third of the travel.

Q: Why does my 250F smoke when I first start it up?

A: Good question. Remember that most of the current model 250 and 450 4 strokes use a 1 ring piston. Less surface friction less piston volume which translates into less weight also less surface area for engine ring to seal. Especially during the warm up period when you first start your bike. I would like to think you would change your oil frequent enough that the oil volume would not be low enough to cause any damage but its a good idea to check the oil levels before riding each day.
