So I got a 2001 cbr f4 for a first bike, I'm riding through an apartment complex and as I'm at the stop sign I go to downshift and I start getting a knocking noise, then the bike dies a few seconds later. It started up for a while (with knocking noise), would drive really slowly, and shut off again. then it eventually wouldn't start at all. Anybody know what this could be?

I'm a brand new rider, and I had my friend ride it back from the city, and it rode fine, also, it was riding fine the whole time I was riding until that point. I do find it hard to get the sweet spot as far as coming out of neutral to first, had the bike die on me many times. My friend (more experienced) didn't have any trouble with it though.

Could it. Be the clutch? Would it make a knocking noise if it broke?
Any insight would be appreciated

dropped valve?

it wont be the clutch, you will need someone experianced to look at it

oreo where are you at in egv? i could potentially swing by.
how many miles are on the bike?

oh and welcome to the site

+1

OP, check out this thread from last year. Sounds pretty similar.

Good luck

Welcome to the site

Not valve if it started latter .

Shift forks are putting two gears together at once.Kills engine .

The shift shaft return spring or bent shift fork.

This is going SUCK but try making a lazy shift through those gears.If it happens again that's it.

oil pump drive chain is driven by the clutch basket. if it was worked on recently, it might not have been put back together right. it could be a million different things however.

^^how would that Kill(stall) the motor?

KILL the motor yes but after that Start???

no oil pressure would make a knocking noise and eventually stall/seize the motor. cools down and contracts, turns back over again.

Ok I get that idea, but would not expect a trouble free ride home.Ouch either way

I think some shit broke.

01 should be an f4i, but that's not going to make a diff that you have something totally out of whack with it. someone, sadly, along the way neglected that thing if you are having that problem.

poor foot work in a wheelie will cause these issues.

More R1 than any others Sorry Yamaha guys but The R1 trans sucks.

my offer to look and listen to it still stands

He's not interested , you ride a Suzuki.

The shift issue might not happen every time.
What happens is the bent shift fork might not fully disengage one gear while your trying to engage the other.
Once the wrong gear catches the dogs it stalls.

Ofcourse this is all just fun guessing,it may not ever happen again if it was just a lazy left foot.

we need more info.

It is confusing did his friend ride it home fine when he bought it or after it died in the apartment complex.?????

Okay, so here's what happened: gas meter reads ful, and doesn't go down. Turns out I ran out of gas. I didn't think to check the tank because I was looking at the meter when it happened. So I go outside and look in there and it seemed pretty empty, shake it a little bit and don't get any liquid noise. Go to the gas station feeling like an idiot and put some gas in a can, fill it with about a gallon, hit the ignition and bam!
Now I need to find out what could be wrong win the fuel meter

I know I'll be remembered on here for this moment, lol but thanks for all the welcomes and offers for help, I know this is gonna be a great forum!

Also, sorry for the late response, all my computers are broken! ( should soon be fixed though)

Well just be glad its just the fuel gauge.

Yea it could be sand in the motor or something like that....

It sounded much worse by your description.

a knocking sound them bam it died.Just goes to show we'll need to hear these things ourselves.

I bet the battery meter is broken on your laptop?

if you put gas in it ever ~125 miles you should never have to worry about that again.


Unless you're uncle steve and get 11MPG on a moto.

I was gonna post:

"Outta Gas?"

just to be a smartass.

I retract all my offers for parts for my track bike. Glad it all worked out.

the meter on those f4i's is only for reserve. it shows three or four black squares which would lead you to believe that its full, but really it's how full the reserve is. when you see black squares, get some gas in there and they'll go away.

Yeah just make a habit of resetting your trip every time you get gas, refill around 100-125 miles or so and you'll always be good.

Be glad it was just a trip to the gas station!

who ninja edited the title? lol!

Lol! I may have to change your screen name to "Got gas?"
