SUBJECT: EXHAUSTING QUESTIONS
on my 88 cr 205r
i want to get a new exhaust on it, currently i have a fmf gold series pipe but stock exhuast if i buy a pro circuit end pipe
will that do anything or what?
The first thing you’ll have
to do is learn how to communicate better than a drunken field mouse. I never heard of a CR 205r. Could you mean a 250 CR?
One never knows these days. If you have an FMF pipe, why would you need another pipe? Will the Pro Circuit pipe do anything?
Hmmm. It’ll give you yet another reason to spend money on your 88 cr 205 for no apparent reason.
SUBJECT: THE MYSTERIOUS KX 250
the 1980-90 model 2 strokes and i had a guy offer me a trade for my 850$ rc truck. It is a Kawasaki KX 250 as he said. He
siad it was an 86 but i really dont think so. Ill try to send a picture. heres the url if that helps. http://it.tinypic.com/r/14msab7/6 thanks and tell me if its a good trade. he says he has sanded it down and painted it since then and it has
an fmf pipe and new renthal bars.
I could tell virtually
nothing from the URL that you sent me. However, some general advice might be helpful. If the bike runs good, just about any
mid-1980s Kawasaki KX 250 is about the fair price for the bike, assuming it runs okay. Sitting down and taking a bike and
making it look pretty doesn't mean that it's a bargain. The most important thing is how it runs. The FMF pipe and the new
Renthal bars are just pluses. Again, it must be a sound bike mechanically for to be any kind of a bargain worth considering.
Here’s a photo of an ’86 KX 250.
SUBJECT: WET HONDA 250 MUFFLERS
i accidentally got water in the mufflers while rinsing off my dirt
bike. what happens to the water when it gets into the mufflers of my 2006 honda 250 cfr.
First off, the bike is a CRF, not a CFR. It was the TWO exhaust four-stroke bike that was made for
only a short period of time, then Honda went back to a single exhaust system. When you get water in the mufflers, the single
best thing you can do is to fire the bike up until it's good and hot and water in the muffler will get blown out or vaporized.
Any time you do wash your bike off, you should plug off the muffler(s) to keep water from entering. A simple rag in the end
will do just fine. About the worst thing that can happen to the muffler is that the water will mix with the oily exhaust residue
and then seep down into the fiberglass packing of the muffler and shorten its life span.
Could you please tell me the year, model, and cc from this
serial # 3V4-050265.
I just purchsed this bike and don't know this info as I do need to get parts. Thank you.
It’s a Yamaha DT125, 80 or 81. And the next time you write, have
the common courtesy to include at least the brand of the bike. If you don’t know that, then you shouldn’t
be allowed to have a dirt bike.
SUBJECT: 2010 MAICOs
Dear Mr. Sieman,
What do you think about the
new Maicos that are coming out? Could Maico ever be as big as it once was? What do you think about the Maico 700cc two-cycle?
Maico has been hopping from one manufacturer
to another over the last few decades. Right now, they're being produced in rather limited quantities and they don't have much
of a dealer network here in the United States. Frankly, I don't see them ever becoming a force they once were.
WHY A KLX 250 WON’T START
i have klx250 1995 i can push start it but not kick start
It probably won't start because the maintenance it received
is about the same quality as your e-mail: sloppy and poorly done. If you would just go through the bike, clean the filter,
put a fresh sparkplug in, clean the bowl of the carburetor and blow out the jets, chances are it would probably start and
run quite well.

SUBJECT: YET ANOTHER BIKE DROWNING
I submersed my 2000 RM250 for maybe
2 to 3 seconds. It fell on its side, as did I...
I got it started again and it ran breifly while spitting out white from
the pipe (water I assume) and then it stalled so i left it alone. I have now drained and replaced all fluids and ran clean
gas through the carbs for a few seconds. the bike will kick start after about 8 kicks but will only run for 1 second or so.
What should I check next? Reed petals?
If your bike sucked in a bunch of water, then you have
to do more than just run clean gas through the carb. And yes, it only has one carb, not multiple carbs as you suggested. You
should take the carb completely off the bike, including blowing out all the jets. Then the filter must be serviced from ground
zero. If you said that you put fresh fluids in, that’s fine, but you should also put a fresh sparkplug in the bike.
Then it should start and run okay.
SUBJECT: STRANGE BIKES YOU'VE PROBABLY NEVER SEEN BEFORE
a nomad-72 that says was built by the snow company of omaha nebraska. i was wondering if there is any information on it or
somewhere i get get parts for it
We didn't have much information about the Nomad model made by SnowCo,
but here's what we do know about it:
The Snowco line of three-wheel vehicles offers
utility as well as sport. And a front ski attachment which replaces the front wheel permits year-around use. Sportiest is
the Tri-Scat with metalflake fiberglass body (shown), leather-type bucket seat, and low-bar, low-pressure ATV tires. It's
available with 5-hp or 7-hp engine, and the 7-hp model comes equipped with standard head lamp and roll bar. The 7-hp Tri-Scat
is also available in a deluxe model with 12-V key starter, head- and taillights, chrome front fork, roll bar and hubcaps.
More utilitarian is the Nomad, also available with 5-hp or 7-hp engine, and equipped with wide, low-pressure knobby tires.
Headlight and roll bar are standard on the 7-hp model. Addition of an optional cargo carrier makes the machine a utility vehicle
for hunters, fishermen, farmers and many other users. The "baby" of the line is the 2 1/2-hp Mini-Scat, produced
especially for youngsters, but far from a toy.
The attached photo is of the unfortunately named
tri-scat, which was the big leader in the airline of the TVs. Send us a photo of your nomad to share with our6 readers. As
far as finding parts, lots of luck.
SUBJECT: CHECKING OUT A BATTERED 1998 YAMAHA RT 180
i have recently bought
a 98 yamaha rt 180. it was ran through water 4 years ago then it sat. the guy before me owned it for like a week thinking
it was a 4 stroke. it will start but it smokes bad and sounds rough when your kick starting it. can you give me a checklist
or somthing to go over the bike with.
The Yamaha RT 180 was a
near bulletproof bike and you had to do something pretty bad to it to make it stop running. I would do a normal checklist
on the bike to see if it's sound or not. This should include a fresh plug, cleaning the filter, completely cleaning the carb,
including cleaning all the jets, changing the transmission fluid and getting rid of the old gas and putting in some fresh
fuel. Then you should do a compression check on the top end to make sure everything is sound. If nothing is mechanically wrong
at this point, the bikes should start and run nearly for forever.
SUBJECT: 1989 YAMAHA YZ250 SPARK WOES
I recently bought
a 1989 yz250 with ignition problems. It turned out to be the ignition coils, and after changing them i found some spark. My
problem is that now it will only run in reverse. I've tried advancing and retarding the timing, but still starts in reverse.
Any advice would be appreciated.
If your bike is running
in reverse, it means that the ignition timing is far too close to top dead center. This was a very common problem in many
of the older European bikes, especially with Bultacos. The timing should be around 2.5 or 3.0 mm before top dead center, but
if you let it slip to something like 1 mm, many bikes would indeed start and run backwards, scaring the living hell out of
most people in the process. Recheck your timing and make sure you're in the ballpark and the problem should go away.
SUBJECT: WHICH PLUG FOR RACING?
i have a 2000 yz 125 which plug is best for racing br8 or br9 it
has fmf pipe is bored out and has vforce reeds
Any time that you're
going racing, you want to use the coldest plug possible. In the NGK line of spark plugs, the higher the number, the colder
the plug. Therefore your eight is warmer than a BR9. Definitely go with the BR9 for racing. For casual use or trail riding,
the eight is just fine.

Are the intake valve and

Not only do I not know
what that the specifications on the valves are on your 50cc El Cheapo Chinese pit bike, I could care less. The fact
that you have one of these pieces of crap tells me that you've don't care at all about quality. So please forgive my outburst
and take your bike somewhere else for information. Where that is, I don't know. And only a few people care.
SUBJECT: BRAKE SERVICE ON A TTR125
How do I check / change the front brakes on a 2003 TTR 125.
The Yamaha TTR 125 is a neat little bike and
changing the pads on the disc brake up front should be no problem whatsoever. Just remove the old pads and put in new ones.
Check there for warps, rust, or score marks on the rotor. As long as everything is okay, just button it up and go riding.

How can I get electrical parts
for a 1990 Yahama RT 180 made in Brazil?
Now this might come as
a shock to you, but you could probably go down to your local Yamaha dealer and find what you need right over the counter.
Lots of bikes are made in Brazil, including many Honda dirt bikes, and you won't have any trouble getting parts for those

SUBJECT: BUZZING SOUND FROM A SUZUKI RM 250
I have a rm 250 2 stroke and
its making a buzzing noise from the engine, i just changed the oil in in a few days ago and i just cleaned the carb two days
ago because the float kept sticcking. after i put everything back together thats when it started making the buzzing noise,
what can that noise be?
Normally, your e-mail would simply get tossed
into the “don't answer” basket, but I recall back to a mid-80s RM250 that I owned that did the same thing. I traced
it down to a reed valve that was frayed and about ready to break off. So I would check this first.
