To start off ive had this 2004 zx10r for about 2 months with about a month of riding since the shop. I bought it used and since got a new clutch on it with new tires. However the 1st thing I noticed is that MY TOP SPEED IS LOW - -Not sure what's the cause. The bike has a pclll(I Don't know what map is has). And the gears look stock. I can go about 76mph in first g and my max speed is only 130-140ish mph IN 6 GEAR! I'm guessing it's the previous owners mapping on the pc3 that maybe gives my bike a fast acceleration for slower top speed if thats even a thing? My only other guess to my slow top speed are that the gears might be AM or my bike needs a tune up? [PC3 and gear images below].
NEXT

LOOSE COOLANT TUBE
I was testing my top speeds and most my fairings flew off lmao. While removing the rest of my fairing this morning I found more trouble. I have this tube coming from the top of the coolant tank that leads nowhere, do you peeps know where this needs to go?

MY RADIATOR IS OFF THE HOOK :/ WILL A NEW RADIATOR HELP?
I FOUND out the the radiator has three connectors. The top two next the the upper frame are busted and the lower connecter snapped. Take a look :/

Lastly
MY FRONT LIGHT DONT WORK!
So my brake lights work fine and my headlights were working when I first got the bike. There's an kill switch for it that is installed that keeps the lights off no matter what until you switch them on.

The headlight only shows these two dim yellow lights. I checked the fuses and the cables are crazy all over the place but look alright ig. Would u guys recommit a new light or new cables?

Well hello!

From the pics and the description of things, you bought yourself a project bike. That think needs a lot of TLC to get it going correctly. There's no way I'd even begin to ride it near top speed without going over everything first. The fairings flew off is the first sign there's something messed up with it.

You can't get up to "top speed" because you're not getting the power out of the engine. The PCIII may be contributing to that, but not enough to drop it that low. You have other things to worry about. Quit worrying about the speeds and pay more attention to the way the power is applied and what RPM you're getting to. The speed is irrelevant and dependent on the gearing used. Power problems in the upper rev range are typically caused by low fuel pressure. You have a blocked/pinched fuel line under the tank, the fuel pump filter is blocked, or the fuel pump itself is old and damaged. But that will keep the engine from reaching the rev limit and stall the acceleration of it.

The coolant bottle has 2 hoses. One from the radiator and one to the ground. It's an overflow line and goes nowhere but down.

If the radiator is hanging loose and missing the lower bracket and the upper mounts, you shouldn't be riding it at all. If the hoses come loose or it cracks and you get coolant on the rear tire, you better be wearing some good protective gear and have REALLY good health insurance.

That headlight housing is jacked the hell up. Those half-assed cutouts and disconnect switch could be causing a lot of issues. The headlights won't turn on unless you've pressed the starter button. They don't come on with the ignition switch. You knew that, right? The yellowish corner lights are the other ones in the housing and are the city lights. If the headlights don't come on at all, then the fuse is bad, the wiring is damaged, or the bulbs are bad. You'll need to check all that stuff.

He bro i appreciate your fast reply and your willingness to take the time out of your day to help and give your knowledge. Yes its definitely a project bike. Wasn't really intentional but it is what it is I cant complain too much im having..or had hella fun with it. Eyes filled with tears haha.
On the other hand your right speed its not the focus, when riding the ride is smooth and feels as normal.the rpms rev high and it idles fine. At higher speeds the rpm just are pushing the 9 10 mark and doesn't seem to have more power to push. But again thats in 6th gear all other gear seem fine. I'm definitely going to do some research and check my fuel pump pressure and see what I can do. And I'm definitely not going to be riding it, it sucks because its my only transportation for now and I just got it from the shop a month ago. Looks like I'm raking the bus again haha. I'm assuming I need to buy a new radiator, hopefully I can bypass these shitty mounts. I checked all of my fuses, they are fine. Positive its the cables not all but definitely a short in one :/. Well I hope it doesn't get worse than this lol i just want the bike to be 100% but I keep finding out things. I'll probably keep this thread updated with pics, etc

Should be a lot higher than 9-10 in 6th gear mate, we can get back to that later. The radiator wont need replacing if it isn't leaking, it looks relatively clean and it would be a lot cheaper getting a tab welded on. That kill switch needs removing and that part of the wiring returning to normal, and i reckon the headlight unit needs replacing, just cant see you getting that water tight the way it is. What history do you have on the bike, know previous owner?

Sorry I said it wrong it has more rpm like it can reach the max rpm in 6th the speed just doesn't match u mean ill be at 125mph at like 10rpm at 6 geam it can still meet the red line like normal just doesn't reach 180.and its a good looking radiatkr i just don't have the broken parts plus idk where to get thag done. The wiring and mounts are going to be the most difficult part. Atleas two far. I have fairing otw so my headlight unit will be ready u think bc itl have new connections. And damn thats unfortunate maybe I'll be able to fix it up myself then sell it for something better but for now its all I got he said it's been slid, the only thing me and my mechanic found was the peg and fairing where scratched and a small dent on the back. Obviously I wouldn't be able to get it back to pristine condition but if I get the little things out the way shiykdnt it run better? I only took it to this shop for sport bikes but should I take it somewhere else that may be more professional? Because I don't think my inspection was super good

Welcome to the forum.
Seeing bikes in such poor condition makes me so sad, why can’t people look after these things, they are not cheap And amazing pieces of machinery! Maybe I’m just anal!

Are the mounts snapped off or are parts just missing?

I use the parts diagrams at Kawasaki as a reference.
Kawasaki Owner Center

I also use the workshop manual...
Service manuals permanently rehosted (again)

I have a Gen4, not Gen1, so can’t help TOO much...

Good luck with the repairs, get her back in good shape like she should be!

Welcome to forum, and to start as others said you really need to go through the bike before unleashing the fury.
How many miles are on the bike?
With all that is going on i would highly encourage you do remove all that add-on wiring crap for HID lights or turning things off and on.
download a service manual, and see what is what, and what the previous "abuser" did to the machine.
based on the wiring loom and other things you pointed out, i would be wiling to bet it has never received much in way of maintenance.
Check all your routine stuff, air filter, sparklplugs, pads, oil, etc etc etc...
download the powercommander software and see what map is in it... do you have any mods that need it?
It really needs a lot of love, and i would be willing to bet the fuel pump might be on its way out as well.. thus the low top speed.

Thanks for the welcome much appreciated. And yea no max speed for me for awhile.
And yea ive been trying to dive into my bike since day one but I this stuff is new to me. I'm glad however this forum exists and alot of people like you on here are willing to help. It doesn't have many miles about 18k to 22k. At work currently can't check bit ill keep you posted. I ran through the owners manuel about 3x, and checked up on the service manuel for the things I've been noticing so far. But you say to follow the guides and see whats original and what's not. Lol that's going to be a hassle. As far as the dyno and wgat I know the bike has it should he collaborated with the exhaust. Apparently it's a really good exhaust, and u think its more than just a slip on. Like a whole exhaust change. Else looks stick besides carbon fiber parts. My brakes and everything basic is fine so far :) I'm not used to the dyno profit if I contest things with ought fucking ky bike ul I wouldn't mind checking. And damn that sucks as far as the fuel pump goes, it sounds expensive and like something that I might not be able to fix myself huh?

Welcome mate. I've been in about that part of the loom this year when I bought an unloved Gen 1. Your wiring looks like a rats nest and those Scotchlocks are hideous.

My ten cents worth....I'd strip out anything unnecessary and tidy the wiring back to stock using a decent pair of strippers, shrink solder connectors and self amalgamating tape to reinstate the cabling into the original loom tape.

I've a "thing" about untidy cabling where generally if it looks like shit it'll cause you problems, Scotchlocks are OK hidden behind a car dash where they remain dry and out of sight but not as part of loom on a bike.

It's worth the effort..

Of course my friend, ask away what do you need to know..I'm no specialist but wiring is best sorted using a multimeter/test lamp and the diagram. I would get rid of those Scotchlocks as part of a good housekeeping project.

jdgun-13 has a point on the fuel pump, it's relatively easy to remove but it's a tank off job and a fuel drain which is a total pita... any bets the filter is clogged, if so it's an easy fix.

On that note I have a spare if you need it, but the filters are washeable and designed to last the life of the bike. Kawasaki don't list a part on the fiche... as I found out.

Thanks btw what are scrotch locks? I'll check the air filter today. It might be the fuel pump I havent checked under the rank yet, hopefully it is so i can get m full power because it rides perfectly fine to my feeling it just can't get to the speed of what it should get to you know? So with these wirings am I just asserting them by taking them out and clumping the same groups together, idk where to start lol

Those are Scotchlocks, made by 3M... being born and bred Scottish I had to look up why everything they sell pretty much is related to Scotch/Scotland and the Tartan backdrops on their tape etc...

Sorry I digress, yea I would remove them, hard to see where the feed is coming from, probably ignition, electrics are tricky, if you've a good auto spark locally let him have a look at it, however I'd check the bike over 1st as it stands.. fuel pump/strainer, air filter too, as OP have said, it doesn't look/sound like a well maintained bike. There's way better, neater and more waterproof ways to connect cabling on a bike.

Electrical issues particularly disconnections and stripping all the shit out is difficult via a forum...
