Mark G: I found this cause I just scored on a barn find.
As I get to know my bike one of three in said barn find I was going nuts
when you hit the magic button so I looked closer at mine and sure enough.:)
Send me an pm if you don't mind about a rough finale tally.
Cory O: I have a yellow 1970 AT1B that looks and sounds a lot like this (except
mine is unbaffled) lol it's loud! gonna put a baffle or washer in the
muffler to quiet it down for road use, just need a high-low beam switch and
probably a throttle (mine doesnt return to idle, once its full throttle, it
aetlas5000: Not being a smart ass. What does it do to the bike when he neutral revs it?
Venomrs4: I have the same bike. Bike mine is complete and has the AAA passanger seat
CR2501A: You idiot. there's no knocking, sound s GREAT! That is the way they are
supposed to sound
newbernbears: Somone's knockin' at the door, check your lower unit bearings, otherwise
Paul McConnell: not bearing, Back in the day we called that piston slap. I is a normal
noise. All the two strokes sounded like that
CaptainNomura: It really is a 1973 Yamaha AT3, 125cc two-stroke single. This one looks
pretty stock and clean except it's missing the front fender, turn signals
and part of the muffler guard. I have the 1971 AT1 and 1972 AT2 model, all
stock. At2 was my very first motorcycle.
Johnq Deere: It allows the engine to literally, tear-shake itself apart, it's like
throwing a rock as hard as you can, without a rock in your hand.. Try it
about ten times and see how your arm feels, engine feels the same way,
piston goes up and down, wobbling, instead of straight, no load on it, no
rock in hand, same difference.. Does this help ? Neutral rev is stupid,
looks cool, sounds cool, but pure stupid for your engine.
CaptainNomura: @calsonicsky Hey, it looks like it has the pre-1972 5-port AT1 engine on
the 1973 AT3 body. You can tell by the engine covers. Older covers had
raised Yamaha logos, AT2 and AT3 models had sunk in letters painted in
black. I guess the engine was swapped.
Nathan Andrew: You wouldn't happen to have just the rubber piece in the petrooster per
chance? Because in my 1973 Yamaha AT-3 125 cc Enduro, the petrooster will not
stop leaking because the rubber piece has been eaten away and shrunk so
that all the gas just flows through the gaps where the rubber piece has
shrunken. So message me back if you have it or if you know where I can find
mamasboypowersports: No, Pennsylvania
aetlas5000: Ah that makes sense. These run at pretty high RPM too so I see what you
