HIGH MILEAGE 2008 Kawasaki ZX-14 Makeover!!

[@tysoncott7402]

mad respect to you fella’s for checking/adjusting the valves on a ZX-14, no need to tell you thats not an easy task on that bike.

[@provenpowercycles]

Def wasn't easy. Luis is a great tech and I'm glad I found him 🤙

[@alejandrotobienne8220]

This why I only FK with these guys. Glad to be in Central Florida. Wish these dudes where here in Orlando

[@nbowling10trio]

Love these old ninjas

[@johnnyappleseedz422]

I have a 2017 ZX-10RR and just went over 42,000 miles. Would've had closer to 60K if I wasn't down waiting on necessary parts from Japan. Some people do ride!! Always appreciate your videos.

[@Thecleananunseenteam]

Mine has 64 thousand miles running like new still great bikes

[@provenpowercycles]

Hell yeah!

[@blancosal]

Just seen your series on ZX14s and I have to say I fell in love with your working approach... You seem really sincere, no rehearsal and overall a cool, integral dude that happens to live from his passion... Had I the money, I'd trust you my Kawi blindfolded without a second thought. Greetings from Colombia!

[@provenpowercycles]

@@blancosal thank you for the good words 🙏 we try to be as real as we can be with everyone! Thanks for the feedback and support 🙌

[@faraitheprod]

Awesome project, love the more detailed videos on jobs you guys do.

[@theonlyredspecial]

These engines are built like tanks. Mate has one with 120,000 miles on it. He services it himself twice a year with 300v oil and changes filters before he should. He has the clearances all set perfect every other year. He really looks after it. Has the cats off it. Straight through and it was remapped. Still makes 188hp at back tyre Some would say he babies by overservicing it but it still rides like a new bike. He doesn’t do track days but can ride it hard. Just never hits the red line and says on the road he would change around 10k if he was pushing hard. Says that’s still more than enough for the road. I’ve only 8,000 on mine from 2020.

[@provenpowercycles]

They are beasts for sure! Properly maintained, these things can go forever!

[@K-carbon]

[@nickrider5220]

Good work. Personally I'd want as much mid and high mid-range to haul the big bike out of corners, trade a little at the top for a chunk in the middle....ie 1000cc type mods not required for me at least !

[@zzrider805]

50k miles is barely ran in. I own an 06 with 185k km / 115k miles since 2014, but I don't thrash it, I'm 58. I do my own maintenance by the book (oil changes every 12k km / 7,5k miles). It's a 1352cc engine and by today's electronic standards is a very simple bike, it only has fuel injection. 0 problems, besides wear items. It'll run forever the way I ride it.

[@tjteknik1]

I know of a ZX14/ZZR1400 with at least 96.000 miles on it. Still running smoothly. If you treat it properly and don't trash it around like a mental sportsbike, but more like a touring bike - it will last forvever.

[@provenpowercycles]

I've given mine more than a few reasons to blow up on me and it still keeps on trucking! It's a very impressive motor to me!

[@tbrowning9643]

Another great video, love all the details. Good job guys👍🏻

[@habitandoproperty2166]

My 2006 ZZR 1400 has got 19 k miles . That's it. Fantastic bike

As long as you take care of it, it will last forever! 💪

[@iantomlinson2422]

Great content! Keep up the good work. I’m ver close to buying a Zx-14R, 2014 w/ 8k miles.

[@provenpowercycles]

Nice congrats!

[@Thecleananunseenteam]

Hope you got it and are loving the bike they are one of the best possible bikes in my opinion 🏁💯

[@zzrider805]

About valve clearances check and adjustment: yes it's harder to do compared to a non monocoque frame bike, because you only have access to engine top end from the sides, but there's room to do it. Better if you take the throttles bodies off. Currently, I'm in the process of adjusting valves. My bike, a 06 Gen1, has now 185k km / 115k miles; last valve check was done roughly @ 70 k km/ 45k miles, which is 110k km / 70 k miles ago (!). After all this mileage, the bike being ridden sensibly, only 2 exhaust valves and one intake were out of spec, and not by much: exhaust spec is 0.22 ∼ 0.27 mm /0.0087 ∼ 0.0106 in.: 1 was 0,18 mm/0,007 in., the other 0,20 mm/0,008 in.; intake spec is 0,18 mm/0,007 in., 1 valve was 0,12 mm/0,005 in. Bottom line: if you don't thrash it, it will last a long time without the need of valve clearance adjustment About spark plugs (NGK CR9EIA-9): the bike's running fine. I'm going to change them just because the bike's all stripped down and it's the first time they're going to be changed under my ownership...so the same spark plugs are on the bike for also roughly @ 70 k km/ 45k miles, which is 110k km / 70 k miles ago (!) Bottom line: if you don't thrash it, spark plugs (NGK CR9EIA-9) will last a long time without the need of changing. As a side note, they came out pretty easily, just like they were on the bike for 12k km / 7,5 k miles...

[@provenpowercycles]

Maintenance is absolutely key in keeping these machines running properly! Couldn't agree more 💪

[@Okj17]

Got 45k on my 2012 and running strong these are freakin beasts

[@jdoubleu4613]

I have 120k + on 2008 same bike. PC5 full brocks exhaust since 3k mi. Many 1/8 runs with extended swing arm. 183@ RW. When first tuned. Last valve adjustment was at 60k.

[@rickeyanthony6596]

I have a 2008 Kawasaki Ninja ZX-14 Special Edition all stock with only 11,500 miles on it. The bike is still like New

[@Onlineghost2ohm]

The valve cover gasket is a common problem (Kawasaki fixed it with a better designed part number too)…

[@captainsensible298]

Losing 30lbs with the old cans AND getting 180 wheel HP means 200hp at the crank, thing will be a monster, 10K rpm in ANY gear means your going quick no matter what gearing you have. 12s and 14s are all stupidly fast. Would have gone with the 200 / 50 on the back wheel rather than the 190.

[@cagonelcopon1]

I have a tuned zzr1400 ‘08, I don’t know who and what has been done but trothle response, massive power from 3k, I had a crack scratched beacause oil pump failure. Replaced crankshaft from ebay, oil pump and mod cover, now is consuming 1liter of oil every 2000km. Anything to check before compression?

[@provenpowercycles]

@cagonelcopon1 once a motor has been cracked open it could be anything. Common things are piston (oil) rings could be bad, valve stem seals, could be that the cylinder walls weren't honed out, etc.

[@cagonelcopon1]

Thanks, so I’ll make a conpression test to start. Thabk you so much

[@blink1397]

What did the work cost the owner? Just curious?

[@hyperbiker613]

Baseline with new mods : 175? New mods and tune : 192? Wild Guess lol

[@provenpowercycles]

Great guesses all in all!

[@nbowling10trio]

I want one too😂

[@aikidragonpiper71]

I thought the ZX14 Ninja was already 197HP stock ?

[@provenpowercycles]

Usually when you see online posts bragging about ho numbers they are being measured to the crank and not to the wheel. 👍👍 Also keep in mind, every dyno reads a little differently too. It's always best to compare baseline numbers to final numbers! You want to look at the difference to see your gains.

[@aikidragonpiper71]

@provenpowercycles Maybe it was from the crank. It was a Kawasaki add when they first created the ZX14. Claiming 190hp to beat the then 170hp Suzuki Hayabusa.

[@K-carbon]

Out of curiosity with vavle clearance does regular oil changes help reduce wear and tear on vavle clearance lovely bike lovely colour

[@Channel-jy1ui]

Valve clearance is directly affected by spring pressure. Valve springs compress with every revolution of the engine so if you ride at 8000rpm, the spring is compressed the same amount of times. Ride for an hour and you just compressed your valves about a half a million times in one hour. And that’s just 8000 rpm. Ima give higher rpm’s. So over the course of a few years, depending on your riding, you can be really beating down your springs. But regularly changing your oil will help lube and cool all engine parts giving them the longest chance of surviving

[@peterfallon173]

Not at all. On an overhead cam setup like the one used on the ZX14, the valves clearances generally get tighter as the valves repeatedly work against the valve seats on the cylinder head. Oil shouldn’t reach the valve and seat if everything is healthy. Not uncommon for quite a few valves to be out of spec the first scheduled check, but settle a bit after. Considering the state of the water pump, valve cover gasket and clutch fluid, I’m thinking this bike was a bit neglected and possibly never had the valves checked.

[@provenpowercycles]

Valve clearance isn't really effected by oil. It's mainly how you ride (what gear, speed, rpms you typically ride around, how hard you are on throttle, how long of a ride you typically go on, etc). Race bikes need valve adjustments much more frequently than what is stated in service manual since they spend a lot of time at high rpm for extended amounts of time. So the valve train sees a lot of heat and gets the shit kicked out of it. Lower reving bikes that also don't see a lot of higher rpms typically can go longer between adjustments as well. Again, just varies per bike and how it's ridden 👍👍

[@leadsled8961]

Do you only adjust fuel ? If your valves need to be shimmed you have a problem or to many miles to be on a dyno.

[@provenpowercycles]

No, we adjust more than just fuel mapping. We adjust any and everything we can in order to smooth the power band out. Shimmimg, your valve lash is periodic maintenance, so I'm not sure why you suggest there is a problem. If you beat on the bike in the street then being on dyno is no different. In fact, I would argue argue it's easier on the bike to be on the dyno vs street since the load bearing is less on dyno vs street.

[@paulboyce8537]

The throttle bodies absolute waste of money with negative gain. Don't bother unless you build full a race bike for the 1/4 mile. That's all they are good for. Pretty sure there would have been fair bit left on the table because of it. Secondary I believe you gain a better result when you just flash to get them open fully and sooner.

[@provenpowercycles]

We noticed tb assembly wasn't a huge gain at all. Thought theoretically they would be better but that's why we do these tests! 🙌

[@groundhoggbullieskennels4605]

[@scotshanley]

These bikes were good back in there day but newer liter bikes just destroy these bikes. My 2022 S1000RR was putting down 196bhp the last time I had it dynoed and it's easily 100-150 pounds lighter with a much shorter wheel base. These bikes are still fast but by today's modern standards they have gotten rather long in the tooth. Great job on injecting mote life into this beast and thanks for sharing the content. 👍😉😎👍

[@crash5811]

M1000RR did quite well keeping up down low w my 2012 ZX14R but wasnt fast enough on the top end

[@scotshanley]

@crash5811 I find it VERY hard to believe that an M1000RR (2020 first production year 212hp and 423 pounds stock) could not only keep up with a 2012 zx14(207.9hp and 584 pounds stock) but smoke it down low and up top all day long unless the rider on the M1000RR just didn't have the balls to twist the throttle. The M1000RR has more horsepower out of the gate and weighs 161 pounds less so either there was something SERIOUSLY wrong with the M1000RR or the rider was rather light in the balls section or the third and in my opinion the third and most likely scenario is the distinct smell of 🐂💩 Even IF your zx14 was making more horsepower then the M1000RR (and its not) its not making enough horsepower to overcome a weight difference of 161 pounds. That's the equivalent of drag racing with your fat girlfriend sitting on the back of your bike and I'm sorry but no motorcycle is ever going to be faster then a motorcycle that has more horsepower then it does while also carrying the equivalent of a second passenger in weight 🤣 Take that 🐂💩 on down the street because we ain't buying here. ROFLMFBO🤣😂🤣😂 P.S. My 2022 S1000RR is putting down 196bhp and 215hp at the crank and I've had it to 190mph and backed out of it because of traffic but she still had more so if you really want to get spanked mines not an M1000RR but it's close enough and it will still happily eat your zx14's lunch and I've got no problem twisting my throttle so you let me know if your ever running through Phoenix and we'll see what your 2012 zx14 will (and more importantly will not) do. ✌️😉😎
