stage 3 spree. need a pipe!!!

[Bear45-70]

Sure salesman always want to sell you the most expensive one. Makes their numbers look better. But the other pipe (MB-5) is for a 70 cc motor.

Mr salesman says those Dio pipes are for 70s as well. And that "its what all the Hawaiians use"

Why I Posted my findings here before purchasing anything expensive

So what its not about who knows more or who can spew out technical stuff faster. At the end of the day its about whos got the fastest bike

You guys do not want me * off enough to start building a racer. Two things, I have a nice budget and I cheat like *. When you "know it alls" start being faster than Tjamz, wheelman and baka, then I might be bothered by you enough to build a go fast. But back in the day all you "know it alls, who really don't know s***" got beaten continually by me and I did it on a very restricted budget. When you have done something special and/or even beaten someone, then throw your challenge until then , you are talking out your *.

That sounds like fun. I won't be able to attend the national rally this year, how about next year?

why dont you try making a pipe you have the other one and i think you have a welder its not hard to do it take time ...

What part of the Iowa pipe is the restriction?

[swimmingfree]

if you cut open the back side of the spare pipe you well see two plate that are the bafull .. just open them up so it move throu faster and it shood help.. i have also put a little larger tip on one and got a fue more rpm ( i think) and gain some speed...

Swimm all you did is just made it louder so it sounds like its going faster silly. Nothing is wrong with the stock pipe. If a stock pipe for a se50 or sa50p can be made to do 50+mph when originally they did only 27-32mph. Stock spree or elite e has done up to 43mph on a stock bore/exhaust setup which is fast considering its a non CVT trans. Its the design of the engine case and cylinder design that limits its power. Not the exhaust.

do you agree that one thing that hold these thing back is the pipe??? ( se50p??? )
if you have a bbk on a stock pipe will it hold back the rpm???
is the tip of a after market pipe lager then the stock???
if the anser are yes the why is it rong to open it up and do this???

Read what baka said. It won't help and 2 strokes don't like a bigger exhaust outlet. Just makes them louder. * they used to use megaphones on 2 strokes and guess what, the small outlet chambered pipes make a lot more power. stokes do not respond to exhaust changes like 4 strokes do.

all i this dose is remove the bafull in it he running a bbk so he need to dum the epent gas out of the motor and yes i do under stand about the back presure thing and the presure wave thing as well... if the tip is the same then its a new clean pipe not one thats full of carbin...

The baffle cut down noise. they do not restrict flow, the pipe size and bends do that.

Now you are contradicting yourself Bear.

just readng thru a couple of threads and i think the bear needs some forced leave

When bear means flow,that doesnt mean air. 2 stroke exhaust is tuned by sound not by the amount of air going through. So using the term back pressure is wrong. And for swimms answer,some after market pipes for 70cc kit have about if not the same size outlet. The size of the j pipe changes size on aftermarket pipes is for tuning purpose .the exhaust is a tuning horn for the engine and not only an exhaust pipe

The design of the exhaust for 2 stroke engines for a rpm range for it to make max power and torque. If you want the max power out of a cylinder then getting a exhaust for that size kit is what you want. But a stock exhaust like a unrestricted se50 exhaust, a bbk can be used with it. Again like I wrote before if a stock engine setup on a se50 with just a variator can do 50-55mph max speed, what's wrong with the stock exhaust. That means that the engine is reving to about around 9400rpms to go that speed. The same for the spree or elite e. Those motors without the gear upgrade can do almost 40mph . What holds it back is non cvt,gearing and block and cylinder flow design. If not it could go just as fast as a stock se50 or dio
