i just put a uni pod filter (1"x3") that removed the air box, and the bike runs so much better with that thing on there. i didnt have to rejet, and the bike has so much more pep to it. i think the uni # is 4112, but it is the best $20 i have ever spent on that bike.

 

Now put a K&N on there and you will notice even more pop

 

ya i had the slowest 50 in the group but i put on k&n and i think i lowered clip 1 now my 50 is a supreme stunting machine

 

I have a K&N and love it.. but it actually takes away from your bottom end a bit

 

where did u buy this at

 

they're all over ebay for just a few bucks

 

yes and you loose torque

 

torque isn't everything.

this is me backpedaling now, cuz my fingers were way out in front of my brain on this one. read on.

 

when you're stunting it is

 

Yeah, i know for stunting you need it, but i was just thinking that Ninja Steve only said it ran better and had more pep. He never said what he was doin with it.

 

thats what puts the hp on the ground

if you had a moter with no torque you wound'nt move

 

Yea I have my airbox modded out for max airflow and my spark arrestor is cut off too. The needle is on the 5th clip (very top) and I'm running 110 octane race fuel (pure C14) in it. The sucker hauls ***. I can get it up to about 40MPH on flat ground (verified by police radar). I think the big street tires help with the top speed a bit.

 

you wont lose torque if you jet it properly.. more air - needs more fuel = more power

 

If torque isnt everything what is? HP? HP is a measure of torque x rpm \ 5252

 

Yeah true, i know all the calculations and engine theory and i guess i should have said that bottom end isn't everything to everybody.

I'm just saying that everyone is so concerned with losing bottom end and for all we know maybe he's just parking lot racing this thing and top end is what he wanted anyhow.

Torque is the basis, HP is the result

 

K&N's are cool if your just stunting it but if your riding a lot of dirt ide go with a UNI. the K&N's just clog up way too fast and you have to end up cleaning them all the time. the POS filter that comes with the Takegawa kits is even worse.
