Score!!!

Does anybody know what this is/where it goes?

As Anderkart said, it's a crankcase vent. Don't plug it, but don't just leave it open either. If you're not going to plumb it to the intake, plumb it to a catch can, preferably a clear one that you can check visually & then detach easily to empty it.

 

[Rustydog2010]

Do you not usually plumb them back in to the air intake? Thats what I did. Is it not to do with the emissions? I suppose if the engine is going on a kart it doesn't matter. If you do plumb it in, do as The Mechtician says, use a clear pipe 'cause it will get full of s***.

oh yeh on my fzr that pipe went into the bottom/side of the airbox. I was swapping engines and couldn't remember where it plugged in either haha.

and yeh you should vent it into a catch can if you don't have the factory airbox.

edit: i should read threads better lol

 

[anderkart]

1990. So it might not connect to anything?
Thanks/

Hopefully you'll find a formed hose in your box of parts that fits perfectly between that valve covers breather fitting and a port on your air box.

It might be OK to just connect a small breather filter to that valve cover breather port if your planning on not using the original style air box. But I've never tried this and dont know if you'd run into any problems or not.

I enjoy helping all I can, but think your going to run into all kinds of little issues like this that only a true CBR600 expert could give you good advice about. Some of the guys over on this forum: http://cbrforum.com/forum/forumdisplay.php?f=12 seem to be pretty dam knowledgeable, I think you should start a thread over there. They'll probably think its really cool your installing a CBR in a kart and give you all kinds of good info nobody here on T/B would know.

We'll still help you out on the kart build here but they'll know more about your engine and probably end up saving you lots of time, money and frustration

Thanks Anderkart,
Anyway, got a lot of wiring done lately, also tried to fix the radiator but no luck. I think I am going to stick the pump hose in a bucket of water and then just have it circulate through that until I get a new one, it can't get too hot while its just on the stand anyway. I don't have the key for it which I would like, so I think I'm going to take the ignition switch key thing to a lock smith and see if he can make me a key. How do you get hte fuel pump out of the gas tank? Does the fuel cap/lock assembally come out? Or do they weld the tank together while its in there? Probably just going to use a little tank to get it running on the stand. Hoping to get it started by next next NEXT weekend, that should give me enough time to figure somethings out.

 

[Rustydog2010]

Do you have any better pictures of your tank? From the ones I have seen, they usually secured inside the fuel tank, or threw the side. It normally has the fuel level indicator on it as well. Better pictures will help heaps.

Jeremy.

 

[robotmickey]

here are some pictures of the tank.

IT LIVES!!! sorta. So I spent about 4 hours on Sunday trying to figure out the rest of the wiring and making sure I have spark and everything. Once I confirmed the spark, I made sure I had a fire extinguisher at the ready, sprayed some starter fluid into the carbs with some gas and cranked it. It turned over about 5 times and the went VVRROOOOOOOOOOMMMMOMOMOM om om om om om om duh. And that's about all that I got. But I got it to start!!. So I hooked up my little gas tank and put some gas in it, tried to start it again with the starting fluid like I did before, but the its not getting any gas. I don't have the fuel pump hooked up because I had it hooked up then it started to get really hot and smoke, lucky there was no gas in it. I figured that I wouldn't need it for now because my gas tank is mounted higher than the carbs, so gravity is on my side. I don't know, I guess I'll make sure all of the lines are clean and the T-joint thinks that go into the carbs.

I also noticed that it's leaking gas from the little rubber boot that holds that carb onto the engine. So I tightened the clamps that hold on the boot but that actually seemed to make it worse. I figured next weekend I'll take the carbs and see what the problem is. It could be just dry rotted or it might have just slip off. We'll see.


EDIT: Didn't even notice but in the third picture, does it look like the boot is torn? Next to the left clamp?

 

[The Mechtician]

What year is the engine? You're correct in that you shouldn't need the fuel pump if your fuel tank is higher than the carbs. As for the carb boots, even if they are cracked it's unlikely that liquid fuel has made it all the way into the intake runner like that, I would suspect a float bowl gasket on that carb instead. You can check the crack on the boot by spraying it with carb cleaner or starting fluid once you get the engine running again. Listen for the engine rpm to increase slightly, which indicates a vacuum leak. In the meantime, order a set of carb boots from your local Honda dealer, or start sourcing them on ebay. If the crack is just a surface crack you can restore the boot by massaging in some silicone oil, but eventually it will crack all the way thru and create a vacuum leak so you may as well replace it while you have the chance

 

[robotmickey]

So I think that I can find a set of those boots for about $30-40. I can't find a set of the carb gaskets so I will have to do a little more searching to find those. Once I get it apart I will diagnose the problem and fix it how I can. I also want to get a new radiator which looks to be like $100 bucks out the door for a new one. So that's like $150ish. I have $144.12 cents in my go kart money account at the moment so we'll see.

Okay, so I accidentally hooked up the jumper cables backwards to the new car battery and now nothing works, I checked the main fuse and it wasn't blown and now I'm afraid that I may have hurt something, or everything. Any ideas on what I should try next?

Try a different battery and check out the ground and positive cables to see if they are in good condition .. Also check out all fuse,relay,and fusible link...

 

[robotmickey]

Its a brand new battery, brand new cables. what is a fusible link?

 

[The Mechtician]

Dude if you've sent reverse polarity DC through the harness, the CDI is probably cooked. They're very fragile, I've seen guys cook them with the 9V battery in a multimeter trying to "test" the CDI. However, keep your fingers crossed and just check the harness thoroughly, go from one end to the other and check everything (except the CDI) with a multimeter for resistance or continuity. Eventually you'll find the bad seed

Get a 12-volt test light and start following the power-flow from the positive battery cable towards your wiring harness/engine.

I agree with The Mechtician, reverse polarity could have easily killed your CDI, but that wouldnt keep things like the starter from cranking the Engine over.

I think there's another blown main fuse or fuse-link you just haven't found yet...

 

[robotmickey]

Alright, thanks for the help guys, I'll look more into it this weekend.

 

[robotmickey]

Alright, there was another fuse that was hiding under a a little rubber guard, it was the only one I hadn't checked and I was feeling like I was going to have to to a lot more searching, but then I pulled it out and it was blown. It was on the starter solenoid which is the first thing off the battery, so when it popped it should have cut the power to everything, like the CDI, behind it, so I think I'll ride my bike to the hardware store tomorrow, get another one, and try it out. Fingers crossed!!

 

[robotmickey]

So I got and new fuse, hooked everything up and................................................................................EVERYTHING WORKS!!!
I was so happy I didn't break anything!!! It ran, so I didn't cook the CDI so that's awesome.

 

[robotmickey]

Well its been a loooong time, but I got this baby to fire up finally and stay running!! I'll try to get a video soon.
Problems included fuel leaks in the bowls, and the spigot coming out of the tank being too small. Also got a new radiator and re-plumbed it.

Congrats!!
