Shielded From The Elements
On a wet day it's a good idea to place foam into voids around the airbox. The foam will prevent excessive amounts of splashing water and debris from reaching the filter and stalling the machine. The last thing anyone wants is to end their day with a swamped quad.
Wheel Wise
If you're looking for added width or maybe even narrowing a machine to your style of riding, a new set of wheels may be the answer. Virtually every wheel brand offers multiple offsets to achieve the desired customer width. Check for available offsets before you make your next wheel purchase.
Reliable Thread Repair
I've seen numerous ways to incorrectly repair threads in frames and engine cases that have been damaged or stripped. There's a simple fix for this problem that doesn't require unsightly gobs of liquid metal or mismatched bolts. Installing a helicoil has a ranking of three on the difficulty scale and will allow use of the proper type and size fastener. Several types of these thread repair kits can be found in automotive part centers or at your local hardware store.
Bag It
Drilling extra holes in an airbox lid for added airflow is quite common. The problem arises during routine washing when water passes through these holes filling the airbox. To combat this minor issue, place a plastic bag over the airbox before installing the lid. This will keep water away from the air intake and ensure the filter remains dry.
