The Bruin was a short-lived utility four-wheeler that Yamaha manufactured only in 2005 and 2006. Though there were two different trims available, the Bruin 350 was the larger and more powerful of the two and could come in either two or four-wheel drive. Yamaha offers troubleshooting help and repair tips for the Bruin 350 in its 2006 owner's manual.

Yamaha outlines a number of common problems, ways to check them, and the procedure for fixing them. However, complex repairs, particularly for mechanical or design failure, often requires detailed knowledge and specific tools. For the most complex repairs, Yamaha instructs drivers to take the Bruin 350 to a Yamaha dealer. But for many simple problems, the owner may repair the Bruin 350 on her own.
With incorrect or inadequate amounts of fuel, the Bruin 350 will not run properly, if at all. If the engine won't start, a driver should first ensure that there is adequate fuel. If not, he should refill and try to start the engine again. If there is some fuel, the fuel cock may be turned to "RES," which could help start the engine. When there is definitely adequate fuel, there may be an ineffective fuel cock. Riders should turn the fuel cock lever to "OFF," remove the fuel hose, turn fuel cock to "ON" and check the fuel flow. If there is no flow, the fuel cock is most likely clogged, and riders should thoroughly clean it.
Another reason why the Bruin 350 may be having problems is that there is no compression. This may be checked by using the electric starter to gauge whether compression is available. If there is compression, then this was not the problem. If not, Yamaha recommends that a dealer be consulted with this complex repair.
Another source of problems may be the Bruin's ignition. Before any repairs should be attempted, the ignition must be dry, and should be dried with a cloth if wet. An owner should then attach the spark plug cap and ground it to the chassis. Then, the owner should use the electric starter and observe the spark. If it is strong, then the ignition system is not the problem. If the spark is weak, owners may attempt to repair by adjusting the spark cap or replacing the spark plug and trying again. If there is no spark at all, then Yamaha recommends taking the Bruin 350 to a dealer.
The battery may be checked via the electric starter. If the engine turns over immediately, then the battery is not the problem. If it turns over slowly or not at all, the battery may be dead or weak. Owners should check the lead connections and change the battery if necessary.
