Cam, carb, and high compression piston. We did this on my friends daughter's 300, it made it haul ***.

depends on what you want to spend you could go all out and get a 330 kit or you could just get a pipe re-jet and air filter!!!
It s all on how much money you want to spend

Sounds like the best bang for your buck there, probably around 500$.... and you could probably use an exhaust when you get a chance. I'd look for a carb off a 400ex on ebay, i'm gonna sell mine on there in a few weeks.

a 400EX carb really works on a 300? is it just a boldt on, or is there mods u have to do? would it be hard to jet? i know that they are not that much, compared to an aftermarket one, but would it be anywhere as good as say a 38 mm PE? i really dont know, looking for answrs

There is a 400 carb for sale on Ebay.

I sold my stock carb to a guy with a 300 for $125.00 he said it made his 300 wake up.

For the money, a pipe and filter and jet kit will be your best mod. A pipe really wakes up a 300ex, I had one that had the stock pipe, I bought a DG for it and it really helped out, then I rode with an FMF megamax and it was even more powerful than mine, so I purchased the FMF and sold the DG to another friend.
With my FMF pipe and filter and jetted right, it was probably close to 1/2 more horsepower, thats about 6hp more or so. If you did that and added a cam it would be REAL fast, a cam is only like another hundred bucks or so from WB.
A 400ex carb will work on a 300, but a bigger carb wont give you more low end power, it will help top end, but thats it. Unless you have a pretty modded motor, the stock carb works best for low end.

500$ bucks would probably get ya all three , cam,carb,piston, get a manual and do it yourself. Just take your time and do a good job. Beats paying a mechanic 60 bucks an hour:grr

eeerrrrrrrrrrr.......ummmmmmm........i think you's mite be leavin some stuff out........if you put in a cam ($100-$190, depending on brand) you HAVE to get aftermarket rocker arms, how much is that? like another 100 bux........piston is 100, plus gaskets if needed $$????............carbs run anywhere from 150 to almost 500.......sooooooo i dunno if 500 bux is gonna get ya there

an all around drop in cams like 120..pistons like 120...gaskets like 30.....carb 150 to 200....like 420 plus throe in the rings,new oil,oil filter, uni air filter......manual...like 500 maybe 550 or 600

If u get a cam i think theres 2 rockers. and there 95 a peice
so its around $300 for the cam
the cam will do for all around performance. low-mid-top

i have a freind with it and he said its GREAT
i have WB pipe/k&n jets/and air filter.

Dude theres a bunch of cams, the drop in, is just that, drop it in.
The next step requires springs, and the high end cam requires springs and hardened rockers.
