1. Upgrade the air intake. A cold air intake will help your Bruin breathe better, which can lead to increased power. There are a few different cold air intake systems available for the Bruin, so do some research to find one that fits your needs and budget.
2. Install a performance exhaust system. A performance exhaust system will help your Bruin breathe better and also reduce weight, which can also lead to increased power. Again, there are a few different performance exhaust systems available for the Bruin, so do some research to find one that fits your needs and budget.
3. Re-jet the carburetor. Re-jetting the carburetor will help your Bruin get the right amount of fuel for its increased airflow, which can lead to increased power. Re-jetting the carburetor is a relatively simple process, but if you're not comfortable doing it yourself, you can take your Bruin to a qualified mechanic.
4. Install a power commander. A power commander is an electronic device that helps optimize your Bruin's fuel injection system, which can lead to increased power. Power commanders are available for a variety of different ATVs, so do some research to find one that fits your needs and budget.
It's important to note that making your Yamaha Bruin 350 faster may come at the expense of fuel efficiency and durability. Before making any modifications, it's a good idea to weigh the pros and cons to make sure that you're making the right decision for your ATV.
