wont start

I am about to purchase a 2001 honda cbr 600 f4i that was in a crash
where it was thrown around a bit, besides cosmetic issues, the throttle
wont spring return and the master cylinder is smashed. It also wont
start, this is my biggest issue, i dont know why but when the key is
taken to accessory all lights come on but when you try to start it, it
wont even try to turn over, no sounds nothing, the battery reads about
13 or so volts so i dont know if thats the problem. The bike is only
$500 which i think is a good deal if i can fix it but i have no idea
why it wont start, any help would be greatly apreciated, thanks.

 

I don't mean to sound cruel but if you have to ask for help here, you
shouldn't be buying such a bike...

 

Sounds like you're not experienced.
Won't start is sometimes a camoflauge for more serious problems.
Cut a wire so it won't run in hope that an experienced/optimistic
buyer will pay too much.
If the seller knows what he's doing, you'll rarely find a broken bike
that's economical to fix. Only hope is to find a bike from the original
crasher...but that's almost impossible to determine as some shops send
bikes home with employees to sell. Crash parts are EXPENSIVE!!!

My favorite garage sale bike story:
It runs great.
Can we start it?
Nope, it doesn't have any oil in it.
Can we put some oil in it?
Nope, no got any oil.
No problem, I have some oil in the car.
Pour in some oil.
Oil runs out hole in engine.
Seller not even ashamed to be caught in a BIG lie...
The least he could have done was stop me so I didn't waste a quart of oil.
YMMV.

It might be the safety interlock system. Check the side stand switch
and the clutch switch and also the kill switch, to be sure you have
electricity flowing through them. The safety interlock system includes
the neutral switch in the transmission, too...

Do you see a neutral light come on when you turn the ignition key on?

The safety interlock system will let you start the bike when the clutch
is pulled in and the sidestand is down and the transmission is in
neutral. That way you can warm the bike up in the morning while it's on
the sidestand and you can be putting your helmet and gloves on...

But, if you put the transmission into gear and let the clutch out with
the side stand down the engine will stop running. And the starter motor
probably won't crank the engine until you put the side stand up. So
definitely check that side stand switch...

$500 for a 2001 Honda F4i is incredibly cheap. I would buy it because I
know that I could fix it. But, why doesn't the person that owns the
bike at least get it running?

 

Im not experienced, this is my first bike, i know a little bit and had
a few ideas of what is wrong but just wanted a second opinion and this
was the most convenient. The guy im buying it from was the guy that
wrecked the bike, he works with me and hasnt had time to try to fix it
lately, nor does he want to spend time to fix it, thats where the
selling it for $500 comes in, he just wants to get rid of it. he
explained the wreck, from how he explained it he was trying to do a
wheelie and it flipped backwards and just tumbled a little bit.
Instead of fixing it he went out and bought a new one and is just
trying to get rid of this one.

 

your right, originally i just wanted to get a car that i could fix up
and eventually just buy a bike that worked but a guy at work wrecked
his bike and wanted to get rid of it cheap because of his lack of time
to fix it so i figured it would be a good oportunity for me to learn
about bikes before i dropped a good amount of money on one. And by
posting a message gave me an opportunity to learn more about bikes, im
sure there was a time where you knew nothing about bikes. We all have
to start somwhere right?

 

Ok... so beside the fact that he tumbled the bike and it won't start....
what was damaged? When was the last time it ran? last year? last month?
last decade? (this could tell more about why it won't start) IE.... how
long did it sit? Did you check for spark? Gas? What year, make and model
bike is it?
The more info you can give, the more help we can offer....

You might start off by getting a bike that works. You can start
learning to the basic maintenances first and then move onto more complex
repairs and upgrades. If you do get this bike, you have a *HUGE*
learning curve to bring this bike to life--especially when you "have no
idea".

As mike posted earlier, replacement parts are EXPENSIVE so prepare also
to spend a lot more than you expected in such an ambitious project.
Expect to shell out "a good amount of money". IMHO, it'll be more
economical for you to get a working used bike first for tinkering and
learning.

As krusty kritter posted earlier too, he *knows* he *can* repair and
bring such a broken bike back to life. He has the knowledge, practical
experience, resources, time and patience to complete such an project.
It may cost you $500 for tuition but will this broken bike just become
an expensive lawn ornament for you?

You are right in that every rider has to start somewhere. You might
want to consider this project more carefully... Again, I don't mean to
be cruel or discouraging but this is a very ambitious project for
someone of your experience. You might want to start with the basics
first. I wish you the best of luck--no matter what you decide to do.

 

The last time it ran was about 10 months ago, that was when it was
wrecked, after that it never started. The guy that wrecked it told me
he thinks there is a sensor somwhere so when the bike tilts to the left
or right at a certain angle it will kill the engine, and if it was
slammed hard enough that the sensor would stick to one side and cause
it to not start. Since then its been inside so its not been exposed to
the cold of winter, the only visible damage is the master cylinder and
just some minor body damage.

 

Ok... we are getting somewhere....First, I would check with the dealer
to see what they think is wrong with it. As them about the sensor switch
and where it is located....They may give you advise on what to do.. maybe
not... if not , then check with another dealer..... not sure how old the
bike is either, as many dealers do not work on bikes that are of a certain
age.... even if they sell the same brand.....Also, get a manual... it is
important if you want to learn how to fix your own bike. There are
schematics in there as to wiring and such that will help you. A manual is
an invaluable tool to have, otherwise get a hammer and start banging on the
bike....
Once you have got the starting problem figured out, and it probably is
something simple, then you could fix the rest of the bike up......
I had a neighbor of mine give me an old honda 750L.... he was gonna take
it to the dump as it wouldn't start either.... plus he was moving... well
let me tell you , its over 2 grand later, but I got the bike fixed and
running well.... it makes a great second bike for me, but mainly, when I got
it, I wanted to learn how to fix it....I already knew most stuff, but I
ended up taking the engine out and having head work done on it, and put it
all back together. It was fun, and took me almost 6 months to do as there
were numerous problems..... and it had been 20 years since i worked on a
bike like that too....
So....... plan to spend some money on getting it fixed, although you
can find parts on ebay or other websites where they sell bike parts cheaper
than new....and will work (in most cases) as good as new....

good Luck with your project....let us know how you make out with it..

"bank angle sensor"

I didn't see the reference to the original bike, but on Wings, they are
typically mounted along the frame under the seat area down under the
side panels. Get a diagram and research it. Most OEMs now have on-like
exploded diagrams to help customers search for the part they need before
ordering it.

 

you try to start it, it wont even try to turn over, no

Maybe the bank angle sensor is stuck in the tripped position or maybe
it's disconnected. Look in the nose cone of the fairing,
centered above the headlight...

If you go to www.partsfish.com, you have to register and select a Honda
motorcycle so you can register it in your online "garage".
The 2001 CBR600 F4i shows both carbureted and FI versions. The bank
angle sensor is shown on "wiring harness (2) page...

If the bank angle sensor is ruined from the crash, there are people on
eBay selling them...

But, how do you know that the sensor they're trying to peddle is any
better than the one you have?

Other riders have asked for information on how to bypass the bank angle
sensor. It apparently shuts off the Honda's computer if you crash...

 

I should have said that the 2001 CBR600 *pages* show both carbureted
and injected models. Honda should actually have a separate parts fiche
for the FI models to avoid confusion...

It's hard enough finding the right parts in a printed catalogue, let
alone doing it from a fiche viewer or online and then, after getting
the special-ordered parts you find they are for the wrong model...

Even the right drawings are sometimes unclear...

I remember one time we were refurbishing a radar antenna, and I ordered
parts for it, according to the drawing view in the printed illustrated
parts breakdown. The mechanic installed the parts he received, and then
he asked me, "Where's the parts for the *other side*?" Heck, the IPB
didn't show the *other* side, I only ordered half as many parts as were
needed...

 

So you had this problem before the PCIII was installed?

Worth contacting the folks at PC and seeing what they can tell you about
it.

 

I just got it started, after taking a multimeter to all of the switches
and sensors i got frustrated and hit the kill switch with a wrench,
immediatly the fuel pumped kicked on so i pushed the start button and
after a while of it turning over it finally started and has started
with no problems ever since.

 

i didnt have to spend any money on it luckily except a few dollars on
some lost bolts and screws. in my frustration i hit the kill switch and
shortly after it started right up and has been running ever since. i
drove it up and down my road earlier and it rides fine so i can only
beleive that the frame and forks arent bent. I take the motorcycle
safety course on may 1st and my permit test on the second. if i knew
how to post a picture if it was possible i would. Now the question
is.... does anybody know where i can get a fairing for the bike that is
less than $400..... : )

 

Maybe you want to check that kill-switch at some point. Applying a
wrench (as a hammer, no less) is not usually necessary ;-) and may
indicate something wrong with the switch-pod. I guarantee that you'll be
upset if you burn that thing out.

Otherwise, sounds like you're on your way. Good luck with the class and
exam. Get good gear and be careful with that thing; it's a whole lot of
bike for a beginner, and there's no sense in having to repair _another_
round of crash damage.

 

Check the mail order companies like www.denniskirk.com and look at the
Maier fairings for Hondas. Also google up Chaparral Racing and look at
their online catalog as well as AirTech and Sharkskinz...

You'll still have to paint whatever aftermarket plastic you can find,
so it won't be cheap to make that $500 Honda look good...
