This is not a problem with me, just trying to learn, and the illustration did the trick. Personally, until I've learned more, I believe in sticking with what is stock, especially something that involves the flow in and out of the engine. This is my first experience with 2 strokers. They are different and that is what I want to learn with my stupid questions.

lots of material discussed here in technical documents as well as 2strokes in general online, good stuff to brush up on

I've been on these forums for over a year and am still asking questions like "what does a boost port do". That illustration clears that question up for me
. I can do anything with a car but 2-strokes are another story, for now!

I vote that animation, or this topic be stickied. i've seen numerous people ask about custom pipes and what not.

Okay, what's a boost port? I don't know either.
The direction this thread is going raises an issue of a need for a glossary for us amatuer/newbies. I'm thinking of starting a thread that could become a sticky.

A engine(2 or 4 storke) with no pipe runs really lean, gotta richen it up. Maybe on Tuesday if I'm not sick I will make a vid of some stuff running pipe less.

EH?! Four stroke has valves and 4 strokes isolating intake and exhaust, which totally changes the dynamic of the physics. Agreed, tuned exhaust increase horsepower, but that's another matter. Born/raised Texan, but been in Missery long enough take on "Show Me" ways. If you're going to do a video, do one on the 4 stoke too. Inquiring minds wanna know.

4-strokes without a pipe, or an open pipe, will run lean too.

Dont have one to run, but I gurrantee you can run a 4 stroke with the exhaust simply pouring out of the block, just gotta rejet so it doesn't run lean and burn a valve(which is why people say you cant, and some say it wont run).

that aftermarket pipe looks cool on ebay but what will it improve? i see that you cant get more than 34 out of your ported and updated spree. hmmmm i can get 32 out of my stock one......makes me think that all that expence is not worth it????
what do you think? unless it sounds and looks cool
Re: Honda Spree performance exhausts?!?

Bump to keep this thread going. You are writing, I am learning.
