I've been having a blast tearing around my neighborhood at 20 miles an hour for a few days now, but I've noticed my neighbors have quit smiing as I ride by. My bike didn't come with baffles and I am wondering if anyone can recomend a supplier. Thanks for your help.

You can buy cheap ear plugs by the hundreds. Pass em out and keep riding!

$200 for exhaust pipe diffusers?! Maybe Steve's neighbors will chip in to defray the cost.

Kind or surprised your bike is too loud for the neighborhood when your using stock mufflers with no baffles . Our red bike is set-up that way and no one has ever complained it's loud or noisey .
If you wanted to try and make some baffles , Dennis Kirk sells steel baffles and muffler packing . Should be a simple job to install . Good luck and Jetblacks right , $200.00 e-bay baffles ! No Thanks

Like Kartgreen said, Muffler packing may be a good alternative for you. My neighbor has a 1980 Honda CM200 that had the baffles removed many years ago....he stuffed muffler packing up the tail pipe a couple of years ago and it is still super quiet. He bought the packing at the local Honda dealer for $15 or so and had plenty left over. Sure can't hurt anything....don't over pack it or it may create a backpressure problem? I watched him and he would poke a coiled fist full in, start up and repeated the process until both pipes had equal amounts and and sounded the way he wanted.

JetBlackChemist, most the stuff I know about these old bikes is what I learned by taking mine apart with a screwdriver and a crescent wrench as a teenager back in the '60's so I've got some huge gaps in what I know. Are you saying those S65's baffles would fit my CA95? KartGreen, is there a youtube of your red bike, I'd be interested to hear it, because I am kind of surprised how loud my bike is with stock mufflers. I will try to link a youtube of it.

I think I might get a pair of those 5 dollar baffles just because they are so cheap and give them a try. One of the neighbors I was worried about bothering has a garage full of Harley Chopper type bikes so now that I think about it a little bit, I think I worry too much.
On another note, my little Honda seems to run better each day I ride it. For the past week I've taken it out each day for about a five mile ride. I've adjusted the cam chain and the carb, greased everything called for by the manual, tightened any rattles and replaced one 50 year old innertube that blew out on me at about 25 mph. The only thing I did to the engine when I swapped out the crankshaft/bearings/rods was new seals and rings. The first day or two it was running kind of crappy, no power, having to shift down on any incline. Here is a link while is was still running crappy.

But after a week of attention and a few miles on it it seems to have a lot more power and it will even sit there and idle without stalling.

It should run better and more consistently so as and when your rings seat. Remember there is no perfect seal until the rings wear in bit. Actually you are supposed to keep to reduced power. My Honda owners book states
"Do not operate at high speeds for the first 500 miles. Do not operate under excessive load or a prolonged high speeds for the first 1000 miles. This is the running-in period."
Which of course sucks (and likely conservative) since I can't put 1000 miles on in a year cause I don't ride enough here in organ donor land.

Its funny to see the words "prolonged high speeds" in a manual for a CA95.

It'll take me a few years to get a thousand miles on my CA95.

BTL- in actuality the above statement was out of my CB72-CB77 owners manual but I recall the same or similar in other owners' manual. :D
