loud and fast

[rickdiculous]

so i took the screw out from the end of my muffler and took the cap and connected pipe out. took it for a spin and could'nt believe the difference. it was way faster and more responsive, no more "four cycling". could i burn something up running it like this? are there some simple mods that i can do and still keep it semi quiet?

I ran my "Bomber" Bike like this!!!
They are really fast & powerful without the baffle!!!!
It won't hurt it running it like that.
The best compromise is to drill a few 3/8" holes in the end of the baffle. (A little more power, a little more noise!)

Remove baffle, replace end cap, enjoy.

HI,

For quiet you can do this.....Large volume muffler means zilch back pressure for all practical purposes....Quiet too!

A classic cherry bomb would look good but I would imagine that the glass pack would just collect the black ooze that normally comes out of the pipe . ...... D.J.

thanks guys. today i port matched the intake and ehuast, cut off the pipe connected to the muffler end cap and drilled the holes in the baffle plate out. it just started raining so i cant take any hot laps. i'll have to get back to ya with my progress.

Too bad we have noise pollution laws here. I took the end out and what a difference. But I did wake some napping kids in the neighborhood. I got to try cutting the pipe as well.

When I removed the baffle from my first engine I could hardly tell any difference when run side by side with a "stock" muffler.

Hey guys im new to the site and I was wondering, I know removing the baffle elimanate back pressure but isnt some back pressure necessary for a two stroke to work properly

 

[Bikeguy Joe]

It doesn't remove all backpressure. A two stroke will run without a muffler, it's just hard to get good throttle response from off idle to upper midrange..

 

[jasonh]

2-strokes run best with the *proper* back-pressure.

I've run the bike with just a 4-inch pipe off of the head...it's WAY too loud. 20 min of that will give you a nice headache, and lots of nasty looks from people.

so i burned up the nieghborhood today. after the work i noticed a bid difference. i still have some spots of "four cycling" but can usually power through them. i'm giving these mods a big thumbs up. try it yo!

Backpressure to a point Recharges the spent unburned fuel/ air back into the cylinder for a supercharge effect, return pulse. Thats why when installing an expansion chamber the design and length are best to be matched to the engine size. With less backflow you will get a higher flow, so you may have to change the needle clip setting, watch your spark plug for lean condition.

 

[badmoon]

running without muffler or baffle do lean the piston and the sparkplug so you will use your piston . ive tried it ...

andrew, could you put a see thru oven door on the muffler, i could cook meals while on the road!!!

Gives new meaning to "Meals on wheels". ROTFLMO

I do service and maintence on these motors and I've noticed
on some engines the lack of back pressure due to no or half a baffle
wrecks the piston rings.

"four cycling" What is this? can someone explain it?

 

[Bikeguy Joe]

It's when the engine is too rich and fires every other time...four stroking.

 

[ibcnya]

Like.....if my carb needle was set on the bottom slot kinda of rich? I think I may have solved my issue tonight. How it got set on the bottom slot, I have no idea, but it was.

 

[Bikeguy Joe]

Yes, just like that.
