There are no cheap hobbies.

Rock and roll,

The only cheap modification I know of for a Liner is the air box.

Either the "Brain" mod. insert 1/4" strip of rubber between the top and bottom of the air box. enlarging the opening and allowing a little more air in and maybe some ram air affect. Comes at the cost of an increase of intake noise but less than some air box mods.

The other leave the top off the air box. Reinstall the filter using the air box screws with washers to hold the filter.

A D&D slip on muffler gains a little but a little over $400. They have a link on their site to a dyno chart. Claim about 7 HP.

If you start to do too much without a fuel controller you may run into a lean engine. I believe all of these come at a cost of fuel mileage and noise.

There are no cheap hobbies.
