The first thing to understand is how does the air filter work. It is simple, it filters particles out of the air that cause excessive ware on your engine; before the air is mixed with fuel to power your motor.
The breathability of the stock air system is poor. It is why most of the time it wont idle right out of the box. I put on a new carb and jetted it. But still it would stall at an idle around 1600 rpms and that's where the idle should be set.
This air filter is a Chinese clone of the Unifilter pod style filter. It works wonderfully! Best $8.00 bucks I ever spent.
My carburetor was already running rich so I got lucky and did not have to change out the pilot jet. The pilot jet controls fuel flow while at an idle. The main jet was running to rich but installing the filter balanced out the air fuel mixture at full throttle. Now my TBR7 runs like a raped ape at full throttle. Ahh Buddy The power and the glory !!!!!
- So the upgrade is fairly easy. First take off the right side cover of the bike.
- Then unscrew the clamp holding the air filter tube to the carburetor.
- Once disconnected from the carburetor gently peel the air filter tube off of the air box.
- Then get a cover to one of those blue totes and cut a piece the same size and shape as the hole in the air box.
- Use Shoe Goop to glue it on. Once dry it is there forever.
- Oil up the new filter, there are many Youtube.com videos that show you how to do this. I used a light coating of motor oil for this job. Do both the sleeve and the main filter.
- Attach new Air Filter. Make sure clamp is lined up with clamp groove on carburetor and is screwed down firmly.
- Start your bike and see if you need to make any carburetor adjustments.
I get more power at full throttle and way better gas mileage using this Air Filter.
Keep the rubber on the road!
