I've got a Yamaha 100cc 2 stroke dirt bike, which is missing the silencer.
It has the header & exhaust, but no silencer.
Will it damage the motor using it like this.
It's not way too loud, it's never used on road.

Double shot!!
I think it will perform better with a silencer on it. I doubt it will hurt it.

By header and exhaust do you mean the expansion chamber too?
The expansion chamber is the vital item, a non-silencer system should do fine, as far as I know most of the silencers are straight through anyway.

Yes totally bad.
There's a bunch of little cunts up the hill that ride loud bikes with obviously gutted mufflers. Sound carries for absolute miles. Pisses me off & I'm a total 2 stroke nut dirt biker etc.
This is how we lose land to ride on.
Stop being a prick & buy a cheapo muffler off TM. It won't hurt the power.
Don't you look at my accountant.
He's the only one I've got.

It's got the expansion chamber and header, just missing the silencer bit
here's a link to a diagram explaining what I mean....

It's a bit noisy to ride around the garden, but I reckon it's quieter than half the bikes up at Woodhill (which is where it will get used). Sound doesn't carry far through the forest.
I had a look on Trademe but could see anything cheap which would fit. I thought about making one, but if it won't be bad for the motor, I may just leave as is (won't go riding it anywhere it'll piss people off)
Double shot!!
If you are taking it to woodhill or any public area, then put a proper muffler on it, or get prepared to be told to eff off.

See picture you posted. No 7 is the muffler unit but contains the stinger section as well. Without it it won't run as well despite what your ears tell you. Just get some pipe about 19mm ID & bend to shape (local muffler place will do it with a piece of bent coathanger for a template & charge you F all). & lead it to an MX muffler off TM.
Don't you look at my accountant.

Forum whore
noise issues aside, it might be running a bit rich and if there's nothing holding the loose end (part 5 on the diagram) the pipe might break off closer to or at the engine.
Go to a wrecker if trademe won't help - there's a good one behind the shops in kumeu (09) 412 5820
