horsepower mods?

[WAKORB]

With me being new and still learning I have many questions and so do a lot of newbs on this site. I was wondering if we cant put together a list of mods, in the order of power gained (not exact power gained because brands vary) I would rather not talk brands but more so the mod itself. Also somewhere say whether it is a mod just for 2 vs. 4 stroke because many mods will be the same for both. Please explain the mod mentioned in great detail. Any disputes will be polled. Also say the cost range. Please quote the thought you may have to add to any existing post. Please  NO tweaky mods like gearing. I will post a new list at he end of this week to see where we are. Please help me in my quest to help newbs on this site.

Thanks WAKORB

1.EXAUSHT [2&4 STROKE]

2.REEDS [2 STROKE]
   a.)accelerates air mixture insuring increased horsepower

3.MAIN JET [2&4 STROKE]
   a.)increases fule flow in carb

4.AIR INTAKE [2&4 STROKE]
   a.)added air box lid holes with prescreen filter to alow more air
   b.) run no air box lid (not recomened) use prescreen filter bag
   c.)two-stage foam air filter

this is only a start please fill in the blanks!

Ignitions will really wake up some of the ffour bangers ..www.procomengineering.com 
Port work from atp performance will give similar results on a 2 banger when properly jetted
Big bore kits will do wonders for either
Jetting either is truely the first step on either ..talk to Chuck Norris about this onre ..also www.billspipes.com   
Learn to jet it properly and you will be very proud of you gained knowledge and the finished product will functio much better " mileage and performance .
Clutch kits work great on either machine .

what is gained in the cluth kit? the power tranfer to the wheels?

[J.D.]

Better clutch=less power wasted in the clutch mechanism.

if you did drop a tooth on the front sprocket to gain torque you will be shifting thru the gears more rapidly to counteract this could you get a new cdi rev box that will allow you to increase your rpms by say 6 to 700 from stock to not have to sh*t as rapidly?

Higher compression head.

This will give you more power throughout the powerband. Too high of compression and a higher octane is needed. But good for both 2 and 4 strokes. But 4 strokes may have to change out the piston due to they have valves.

What else has to be done to properly prepare for high compression? Are better gaskets needed? Different sleeve? Won’t this increase the chance of detonation? Does timing have to be changed? Are airflow mods required?also will I need a new higher prfomance crank?
