04-10 Kawasaki zx10-r Cylinder Head Swap Comparison, Part 2, Explained.

[@johnmcgrath3907]

I've heard 1000 people ask this question. Thanks for making sense of it.

[@KINGHARGRAVE]

Great video glad somebody finally did a video explaining the variations

[@everydayirace]

Thanks buddy.

[@FirstLast-tx3yj]

@@everydayirace hey man love ur videos everythings straight forward and clear. Have you ever tried porting?? How much will my bike pick up if I port my head?

[@everydayirace]

@@FirstLast-tx3yj I haven't done any porting and couldn't tell you how much power it would pick up, because 2 hand porting jobs are never the same, one can pick up power and the other one can lose power and they would both look the same to untrained eye if you get my drift.

[@FirstLast-tx3yj]

@@everydayirace i was considering porting my own head but I have no idea how its gonna turn out!

[@everydayirace]

@@FirstLast-tx3yj give it a try if you got a spare head, it's more complicated than just making ports bigger.

[@MDZ7722]

High tech video, @nd added detail of all the variations plus remapping!

[@steelcitycaprice.899]

im soooooo thankful for your posting cause i just change my exhaust. bike was sounding great and seemed like it was still running great but three weeks ago valve retainer broke on way home from work and this weekend i opened her up and damage is piston and cylinder. 😤 so now im looking for engin cases.

[@everydayirace]

What year is your zx10r?

[@TEAMWRIGHTEOUS]

This info has been very helpful, but we've ran into some issues after getting it back together. Do you have any social media platforms I can dm you on and bounce some questions off of you? Any help would be greatly appreciated.

[@billanderson6089]

Hello sir ... I have a 2005 ZX10, it has a broken clutch rod and 2nd gear doesn't want to engage under throttle ... do you have any ideas why this happened???

[@iamonlyhalfawakekinda7631]

Great video

[@behkhill2557]

Awesome mate :D thank you

[@bcracing103]

I currently run a 05 race bike but would really like to run the gen 3 dash. Ive watched your dash video multiple times and was wondering if you could make a video of how you made the harness adaptor from the original plug to the gen 3 dash plug. That would be amazing

[@chriatiansandy6233]

I needed this lol

[@Moto_]

Great info keep it coming.

[@leadsled8961]

Was your gen2 dropped valve a 2006 ?

[@victormassaharuwatanabe7347]

Are the camshaft holders the same on all three models?

[@bcracing103]

Would a later model zx10 full exhaust system fit the earlier 04,05 model. I ask due to the lack of availability on the older models. Do you know if there would be any clearance issues ect? Thanks for any advice you can off on this

[@everydayirace]

I don't think it will, won't clear that oil cooler hump that 06 bikes don't have.

[@mi16pim]

If i may ask for advice, what route would you take? Looking for a bit more power, mostly riding my bike on tracks, no dragracing. 1. Swap a gen 3 head on a gen 1 2. Swap a gen 3 intake cam to a gen 1 head

[@everydayirace]

You already know the route I took........boost.

[@bacchusthompson5834]

@@everydayirace I have a few questions about my Gen. 1 Build... I have a Ported & Polished head for my Gen. 1 I got my hands on a Race Intake Cam and was wondering would a Gen. 4 Exhaust Cam work well with it? I'm staying N/A and would like your input on what Cam Combo would be best. Also, are the Throttle Bodies interchangeable between Gen. 1, 2, & 3 ?

[@everydayirace]

@@bacchusthompson5834 I've never tried gen4 exhaust cam, so I don't know if it works. I made a video about throttle bodies swap, you can look that up and decide for yourself if that's for you. Now will it make anymore power is going to depend on the engine management system and the person's tuning ability.

[@bacchusthompson5834]

@@everydayirace will look that up and see what information you gave... Have you tried running 2 '08 Intake Cams in a Gen. 1 head before? Just want to build a motor using all OEM Kawasaki parts for cheap reliable horsepower. I do a lot of commuting (about 14k in a year), so I do want it reliable.

[@edh4686]

I got a question for you I am currently looking at a 2005 ZX 1000R, it supposedly has a bad head gasket. Is that common for that year bike. Also can I just replace the head gasket without having to take my head to a machine shop. Thanks

[@everydayirace]

It's not very common, but it happens. If you want to do the job once it's a good idea to take the head to the machine shop, while you're at it you can deck the head and get little more power out of it. Before all that you might want to do more testing to find out exactly what the problem is.

[@antoniaydin]

Hello I was wondering why are the exhaust ports not fully open like the intake side of the head? I never seen this before with a cilinderhead.

[@everydayirace]

To increase velocity of the exhaust coming out of the ports.

[@daleward5198]

Will gen 2 intake cam fit gen1 head ? Is it a straight fit in ? If it is a straight fit in what valve clearances gen 1or2 ? Thanks

[@albertwhite8218]

What camshafts do you recommend with this swap ? I have a gen 1.

[@justincampbell7938]

I have a general question you seem like you know a lot about these 04 ZX10R so basically I took my engine to the shop to have a head gasket replaced it wasn't really leaking that bad so they've had it for about 2 months I call them today and ask them what's going on they told me that my motor was trash and when they were installing the head they can only torque it to 25 ft lb and the threads ripped out when they were putting the head on have you ever heard of something like that happen and what is the easiest way to fix that I've heard I could do a helium coil but also was told that there could be too much pressure and the bike has too much torque that it would not work what would be your suggestion and also I've heard of them saying I can do a Time sert so please get back to me soon as possible and let me know what you recommend because buying a new casing block is out of the question I've also heard racers usually weld in studs with a aluminum welder and put on lock washers and nuts on the top to make it easy access for the head to come off please let me know what you recommend soon as possible

[@everydayirace]

Block is aluminum, pretty common to pull threads out especially when using aftermarket head bolts. Time cert is better than helicoil, but if it was my engine, I'd replace engine cases.

[@dustantraver6829]

So what you're saying is if I have a gen 1 go gen 3 for the swap right lol

[@mi16pim]

Have you done any back to back dyno's with a gen 1 stock head vs swapping to a gen 3 head. Is it worth it in your opinion?

[@everydayirace]

No I haven't done it.

[@suspensefulness]

swap the gen 4 head on to my zx10 2004.., possible or not and is it worth it to gain more HP?.. great channel👍🏾

[@everydayirace]

It's been done before.

[@suspensefulness]

@@everydayirace is it worth the headache and money...or can i jus to this 600 frame 1000cc bike😂

[@Alex-xp2lb]

Question, so I am looking to put a gen 2 motor into my gen 3 bike (I am having trouble sourcing a gen 3 motor...) and I am curious, if I wanted to put my gen 3 cams into the gen 2 head do I also need to replace the valve springs? Anything else I would have to do? I want the motor to run as close to the gen 3 performance as possible... I would also swap out the valve spring retainers, good idea? Bad idea? Sorry for the long winded comment. I would love some input on this as I do not know for sure what I can do without creating long term problems.. (this bike is my daily)

[@everydayirace]

The gen2 engine will bolt right in, replacing springs isn't mandatory, but you can along with gen3 retainers. Gen3 intake cam with gen2 exhaust cam would work the best. You'll also need to switch stator or stator plug, they are different. You can also replace the head gasket with .55 or .55mm to boost performance, but the engine will run little warmer. Shifter will have to be flipped too or you'll have a Moto gp shift pattern, intake boots are also slightly different, might need some trimming.

[@Alex-xp2lb]

@@everydayirace thank you so much for the input! So just to confirm what you've said, I can go without swapping the springs and just swap retainers out, then use a gen 3 cam for the intake and leave the gen 2 cam for exhaust. Might need to trim the intake boot (if new motor does not come with one). Flip the shifter so that the patterns arent reversed (not sure what that entails?). I have a new stator for the bike so that will fix the issue with the plug. Do you think this thinner head gasket is worth me tearing apart the new motor for? I don't really want the issues with heat too much as this is my daily... Another question that just popped into my head is will this set up work fine with the secondary injectors added in on the gen 3? I know that you had mentioned before that the intake valves on a gen 2 are not titanium while the gen 3 are, just want to ensure I won't be over stretching there worth. Thank you so much again for helping me out with all this! It's huge to me! Gained a subscriber for sure today!

[@everydayirace]

@@Alex-xp2lb pull all the springs and test them, if they're in good shape use them, if not replace them. Everything you mentioned is correct, use gen 3 throttle bodies and all the efi parts will work just like before. I installed a gen3 engine in my gen2 bike, the same way and it ran great

[@Alex-xp2lb]

@@everydayirace last thing, and I'm really sorry for taking so much of your time, I'm thinking if I leave the exhaust cam alone then I shouldn't touch anything on the exhaust side and just do intake springs retainers and cam.. Is there anything wrong with doing this?

[@everydayirace]

It's fine, just check all retainers, otherwise you'll be looking for another engine if retainer fails.

[@kinglouis6974]

Why not just tune the head that you have ?? Port polish and skim it , you know it will definitely fit back on , I rather do that then to just try and get more power by just putting a newer , older head on it ,

[@brandonrohrer7914]

I've always wondered this being that the bikes all look the same. I wonder it the motors can be swapped

[@everydayirace]

You had me at "bikes all look the same".

[@0045Cory]

So I’m going to swap my 06 head for a 2010. Should I have it mapped before I even try to start it? I think I’ll have to talk to some local dyno guys before I go through with it. I got a head for the price of all new valve retainers.

[@everydayirace]

Swap the head, have your tuner adjust fuel and ignition timing and you're done.

[@0045Cory]

EVERY DAY I RACE Thanks! I’ve been looking at other parts I can update my 06 with, and I’m wondering about the Showa forks on the new 10’s, steering stem included maybe. Do you have any input on that? Thanks again, and I’ve been enjoying the videos!

[@everydayirace]

Unfortunately I don't know if newer forks will swap. But you can always install aftermarket cartridges and springs that are correct for your weight and riding style.

[@Moto_]

@@0045Cory the fork swaps.

[@digisuboob]

i wonder what the power gain is on a gen 1 going to a gen 3 head

[@everydayirace]

I posted a dyno graph on what the gains were in the other video.

[@Stage2_392]

Will the gen 4 head fit gen 2 block without modifying.

[@everydayirace]

gen4 head will bolt on to gen1-gen3 blocks.

[@Stage2_392]

@@everydayirace do you know if any modifcations needed for sensors or anything. Which timimg chaim to use. Supposedly the head sits up a little higher on the intake side.

[@everydayirace]

You will need to drill a hole in the head to install a cam position sensor, unless you're running a stand alone ecu. You will also need to fab up mounting point for the engine mount. And coolant port is also in a different location. You can compare the 2 by looking both heads up on google image, all those 3 things are visible.

[@WRENCHGODLLC]

@@everydayirace is it worth doing all that to swap over a gen 4 head to a gen 1 engine? I'm wondering cause i plan on keeping mine but i want to put as much new kawasaki products on my gen 1 as possible

[@everydayirace]

@@WRENCHGODLLC it all depends on the person.

[@jacobmcc7778]

Any difference with headers fitment? Like if you put a Gen 3 head on a 1st Gen would you then need Gen 3 headers also or would the stock headers still fit? Thanks 😁

[@everydayirace]

Same exhaust ports on 2004-2010, use gen1 header on gen1 bike.
