the easiest mods you can do if you have a stock head pipe you can take off your head pipes and grind down the welds this will help with the flow.
get for $15 you can get advanced timing pin and it will also make an effect. Maybe put a slip on muffler and a high rev cdi box and you should have a nice little set up...

I would not recommend the step key ignition, I have had 4 of them shear on me. Do not touch your flywheel.

Sparks says not to use the key on 440s or bigger cause they already run hot, and the key makes them run too hot.

Unless you have a built motor the timing advance does you no good, your motor cant handle it. ANd as far as the header mod goes, your increase is not even worth the time you spend filing them down. The CDI and Slip on however will have a little bit of an increase over stock.

Dont forget cam timing you can slot your cam sprocket and degree the cam for some extra ponies.
