more power??

So I would not say that you get an increase in power but there is an increase in throttle response to be found. I got a pro design manifold which is a billet manifold and a VF3 reed cage. The VF3 cage had to be modified to work with the manifold so in getting them to match I ported both. This did not make a top speed difference but the throttle response is instant and amazing when compared to stock. ... And I second the reed spacer ... skip it unless you need room for bigger carb
 
No differance in power, but better throttle responce for sure. The reed spacers are not what they claim to be so save your money. If you want some cheap power do a timing advance, it will help a lot.
 
X2 on the Boyesen PSR reeds and tradeing in your fatty in for a set of Toomey's They will make a very big difference. Thats my opionin
 
You can change the time that the spark occurs, by advancing the spark some extra power can be achieved.
You can buy a kit, or if you have a little mechanical knowledge and a flywheel puller you can do it for free. Whichever way you go you will need a flywheel puller.
Don't advance more than 4deg BTDC
There are instructions on how to do it here on the site but for the life of me I cant seem to find them.
Some king person will post a link I am sure.
