hey everyone,
i read an article about how the direction of you spark plug can give you additional power so i was wondering if there are any other hidden factors that people can change for free that will increase the performance
and i dont mean race exhaust etc im on about practically free adjustments for the average joe who doesnt want to spend a great deal of money on a quad or atv (possibly oil type)

 

Not completely free, but..... put some holes in the air box lid and jet up to compensate for the extra air flow, 4-10 dollars for a few jets. Pull the baffle/spark arrestor out of the exhaust (make sure thats legal to do where you ride,or install a screen tip to comply with law) Chain drive quads- make sure chain tension is correct and chain is properly lubed, and axle housing bearing turn freely. Small things, but driveline drag can suck up horsepower more than you know. Brakes- make sure they are not dragging or sticking. Front wheel bearings, make sure your front wheels spin easy. Correct air pressure in tires, too soft, tires sqaut and dont roll as easy, but dont overinflate or they wear fast and ride bad. All those things are free or very cheap, and add up to a few horsed here and there.

 

ok thanks man and sorry for the lack of terms but what is driveline drag?

 

Anything that makes it harder to roll your quad...sticky bearings, too tight chain, sticky brakes, they all create drag, increasing rolling resistance, and taking more power to move.
And dont worry, its good to ask questions !!

 

ah ok man and thanks for those performance tips

 

If you have a Yamahaha 450, you can change the timing. It's about an hr or so job but it's free.
Knowing what machine would help.

 

haha well unfortunately for me it is only a Chinese atv, i know, i know its a piece of **** but its all my budget can allow for but im getting great knowledge about how engines work from all the repairs!! hahaha

 

On my 400ex I just removed the head pipe and ground down the welds by the flange. The welds are built up by where it bolts to the head . Might uncork it a little.
