What are you talking about?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Most two stroke bikes made since the mid 80s are equipt with powervalves. Powervalves are valves in the exhaust port that open and close according to rpm to effectively change exhaust duration and port size. They stay closed at low rpms to keep the port small to encourage good low end power. They open up at higher rpms to give the engine more top end power. How are you going to fix your bike with them when your bike already has them?//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

And your engine having an air leak has nothing to do with how your pipe "hits". The only way a pipe can change the charactersitics of your powerband is if it is a different shape. Im sure your bike runs differently now but it has absolutely nothing to do with your pipe.

It sounds to me like you need to learn alittle bit more about how your bike works and how to maintain it before you blow it up...//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

^ Yeah if you get a 2 stroke make sure it has powervalves. Give you much more bottom endMy Banshee is a beast with the powervalves.

Most modern bikes have powervalves. If you get anything post 1990 you should be good to go.

The only bike I have riden with no powervalves was a 1985 rm 125. It had absolutely ZERO bottom end. That bike had a powerband like a light switch, it was either off or you were flying. Talk about a harsh hit, it was the furthest thing from a begginer bike.

Kinda like my Banshee was before I got the 521 Cheetah powervalve It feels like a yamaha raptor 700 with a turbo

I bet it moves along pretty well now compared to the stock 350...

If I ever got a quad it would be a banshee. Soooo much potential to hurt yourself...

 

[JBGabriel 10+ year member]

Yeah the guys at the dunes where I used to ride rode Rappy 700's and could only pull 2nd maybe 3rd up the big hill
I pulled the top of 5th and I'm geared at 100mph

How much did that motor run ya?

i think i need to learn more too!

but its what it was, my jetting was the same, same temps i rode the bike down the street with the cracked boot, replaced it, rode down the street and the pipe hit wayy the F earlier.. its what happened, the bike runs completely different.. its like it dropped a pilot jet and main jet 2 sizes, thats how lean it felt... and the gears were shorterr too.. so i adjusted jetting and fixed most of it but i need to change the spring i have for my valves..

and power valves what i mean is the spring, changing the spring you can change the rpm range +- 1-2000 for which the pipe will "Hit" and hence spin tires

I actually sold the 350 and bought the 521 for $5200. (whole bike)Oh yeah and it had 35mm carbs when I ran it last I got 39's on the way with big bore shearer drag pipes and a lockout clutch

Should be pretty insane. And loud

Depending on how serious you are you may want to get the shocks revalved for your weight because they are usually valved for lighter people. Also depending on the adjustments you could just try to up the spring preload and add some heavier fork oil and/or put more air in the forks, just don't blow a sel with to much lol!

i hope your joking

k here is what i think if you start off riding a dirtbike for the first time in sand your going to get real frustrated. trust me ive been riding for around 8 years or so and im just getting used to riding in harsh conditions. i think you should look in to a ktm 300exc it is a 2 stroke and it has e-start if you get the new one(i think) and plus a 300 will have plenty of power or you might consider a 250exc. but i have a ktm200mxc and it pulls me around just fine and i weigh 170 so you should be fine on a 250 or 300. and a good thing about ktm's is that you can beat the living hell out of them and they wont break. they are probably the toughest trail bikes on the market right now and really reliable. just a thought

mitch

lol more air? roflzzzzz

wouldnt ya wana to kinda bleed them a bit more then fill? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif:crap:

 

[mirracomitch 10+ year member]

no you dont want air in your forks haha

 

[bterz 10+ year member]

In my opinion, I suggest a KTM 450f

Electric start

Great suspension

The price for matience is a ***** on a 4 stroke but they run forever if you maintain them, by doing simple things like changing the oil / oil filter / air filter etc

Depends on what kind of riding you're going to do also.

My 250f is for sale if you really want a 250f. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Its plenty fast, too.

PS: Bleed your forks before EVERY ride. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif dont put air in them

 

[blazer316 10+ year member]

some forks have a spot to add some fyi

 

[blazer316 10+ year member]

a pos bike we got around here we used thicker oil and charged it with some more air pos xr forks

Some older bikes have air forks. And yes you could adjust them by putting in different amounts of pressure. So once again you guys need to learn alittle bit before ripping on other people.

 

[JBGabriel 10+ year member]

I still say a kdx 200/220 for a cheap bike that is good all around. PLenty of two stroke power and they can be found very easily for cheap.
