KAWASAKI Z900RS Full YOSHI SYSTEM. ECU REMAP AND DYNO TUNE 😎

[@kens5871]

Yoshimura pipe sounds good and proper like how a inline four should sound. Growing up in the '80s I'm partial to i4 engine and not too hip to parallel twin sounds.

[@seanryan9846]

Still super happy with the bike Chris. Just rides epic. Glad to see the really positive feedback on the feed. Outstanding work by you and the crispy team. 💥🏍️💥

[@bradrook3919]

Excellent vid. Well Done! Indeed the only video out there at trying to squeeze out more h.p. from this scooter

awe man i love the snarlry old school sound

[@dco956]

Love that Yoshi.... without baffle please.!!!..old school like mad Max...and the green.havent seen that n the US. ....sure miss my 84 red GPZ 750 w Yoshi 😭

[@gordonwallin2368]

From a guy who has a 2004 Z1000-very basic, but a sweetheat of a bike, and dyno'ed at128.8HP, only 498lbs, so, it goes well and eveen an old guy like me can pick it up-this is the closest I've seen to replace my baby. Again, Cheers from the Pacific West Coast of Canada.

[@sparkatron9334]

Just watched this video with the CC subtitles on (English Auto). The bit with the bike running up and down on the dyno (17.26ish) comes up as MUSIC then APPLAUSE. For a Zed900rs it says it all really.

[@crispysmotorcycles]

Haha! Yes indeed it does! 😎👍🏻

[@TheCelticlion]

Had a Honda 750/4 F2 in 1980. I fitted a Yoshimura pipe on that. It was carb so with some advice set up the carbs and jets myself plus a few other things. Didn't dyno it but from the feel of the bike the bhp and torque curves look similar to your plots. Lifted everything through the rev range, with no flat spots or dips which some other pipes could cause, but also gave a nice fat lift in the mid range torque over and above the general lift. Great to see a Yoshi delivering the goods 40 years on.

[@bigbad253]

When I was a boy, a long time ago, I had a 1977 Z1000 with a lovely aftermarket 4 into one (vance & haynes) with a large baffle. Late one evening, I was making my way home on a country highway when the last bolt holding the baffle in place must have sheared through and fallen out, followed shortly thereafter by the baffle. It was like an instant switch in sound from healthy litre bike at 6,000 rpm to steroid abusing semi truck at 120 decibels or better. I did find the bafffle and discovered another benefit of using loctite when doing the repair.

[@chriscarbaugh3936]

That exhaust is totally bad ass! I think the Dale Walker AirBox mod might help w a few more ponies! Damn excellent little vid. Wish you guys were local!

[@crispysmotorcycles]

Thanks Chris! Yes we did discuss airbox mods with the customer. Possibly something for the future 😊

Good work! I mean I've already got my heart set on one of these but finding decent tune videos isn't as common as you'd think! Appreciate this a lot! *subbed*

[@guymorris7860]

Loving it Chris👍 Awesome video. Really nice having the blip down clip and some nice full pulls up through the box. Plus the new pipe sounds really good too.

[@crispysmotorcycles]

Was crazy loud without the baffle dude! 😅

[@craigoverall5753]

Dale Walker USA (Holeshot) did an excellent exhaust,airbox, module tune and gained around 18ftpounds torque a quite a few more ponies. Thanks for your efforts on the 22 model and like the Yoshi pipe. Will you try the Delkevic decat header and or the 4 into 4 for interest sake with stock maps and air filter. It would be great to see before and after.

Great video. Thanks.

[@jean-pierrefernandez2460]

all the yoshimura diciples wanna know... can you add the yoshi cams and still do all the changes via ECU flash? and if not what other mods are required ?

[@paulhewson4600]

Harley has been using CanBus since 2012ish, its an easy system to learn, with the right tools of course

👍good work

[@JesusIsLord7773]

when you downshift do you rev and clutch and downshit at the exact same time when downshifting?

[@crispysmotorcycles]

Hi, yes pretty much. I also find it helps if you are smooth with the clutch 👍🏻

[@TopshelfJunior]

You don't HAVE to do it the way he was in the video, although the way he was doing it was spot on and SWEET ! But on the Z900 especially, you can pull the clutch in, kick it DOWN a gear, and slowly let out the clutch...and the bike will still be smooth as butter. I don't know what it is on the bike but, moving between gears on it is a breeze, up and down, always smooth.

[@SmittyOne883]

Music to my ears fellows. A Yoshi is a must have no doubt about it and maybe chop a third off the baffle for extra joy 😂

[@1913medellin]

Crispy I want to make a logo design for you for free, had some cool ideas if you are interested!

[@colinoz]

Does it have a quickshifter for upshifts? Or you're just going clutchless?

[@crispysmotorcycles]

No Quick-shifter on this one, just old school clutchless gear changes. 👍🏻

[@colinoz]

@@crispysmotorcyclesDidn't think so. Just looks like it clicks into gear nice and easy!

Love the old school Z900's these new ones are really nice old/new school tribute to them - That exhaust is a great choice sound epic totally agree " Loud pipes save lives " 😎👍 Great video new sub here ride safe guys

With a good remap/flash, that yoshimura exhaust should push 135hp to 12krpm from or 100hp 10krpm. Me, no baffle😅😅😅😅

[@crispysmotorcycles]

135 bhp from a remap? That would be impressive…. The RS is a different beast to the Z 900 but with different cams and a remap you’d be closer. Check out - kzbin.info/www/bejne/hl7HlpaDodOhnK8si=W20PIXmf1qxWsZh5

[@switchblade762x51]

@crispysmotorcycles yoshimura cams, are different. With them, the yoshimura hand bent superbike pipe, Archi and a few other jdm companies are pushing between 130 and 135. If you add in the high compression pistons heads etc($3k) you get closer to 150hp. JDM just does it better

[@crispysmotorcycles]

Yes you would definitely need to do engine mods to get those kind of numbers, not just a flash and exhaust. Baffle out was 😳😳😂 Thanks for commenting 👍🏻

I would never make any changes to my Zed that made her at all louder. Running in "just a whit under open headers" mode is a really poor decision, imnsho. To each their own.

[@ampelec]

Modern bikes run lean and hot to comply with emissions standard's. Nothing else. Free flow filter and exhaust, and then a proper Dyno tune is the best thing you can do for this bike.

[@iNFiN3]

Is this exhaust street legal for european countries? cann it be homologated for lets say germany?

[@crispysmotorcycles]

Hi, the exhaust isn’t marked “not for road use” and with the baffle isn’t crazy loud so I can’t see a reason the Police would be interested and it’s quiet enough to pass an MOT. Here in the UK 🇬🇧 anyway 😎👍🏻

[@petraklavcic6196]

@@crispysmotorcycles must be homologated. The police will not mesure, but will ask for homologation papers. So I think this pipe is not legal in EU. In Slovenija not.

What where are u located

[@malexder0082]

Now that you have the map, the next flash costs you basically nothing, right? You don't mention anything about the O2 sensor. Did you disable that and advise the customer to unplug it? You should also plug the hole left behind in the air box after removing and plugging the hose. Cutting out the divider inside the airbox is also another mod people do at the same time. Changing the air filter practically makes on difference (+1 hp maybe?). New exhaust, filter, airbox mod and tune should get 20hp more.

[@crispysmotorcycles]

Hi Malexder! The flash costs as long as it takes me to do it. If it’s the same bike with the same mods I can apply the same map but personally I’d like to run it on the Dyno and check everything. Yep, I disabled the 02 sensor and unplugged it. 👍🏻 No need to plug the air box hole as I’ve tuned the bike to run without it. Pair valve is now blocked off. Yes performance air filter makes small gains but some people prefer a lifetime filter that can be maintained. This one made an extra 12 bhp peak over stock but the Euro models tend to be less restricted. It’s not just about peak power figures tho 😉

[@seanryan936]

Chris, well a few more thousand miles on the bike since the video. Still totally loving the bike. It's just so much fun. Thanks mate. Good to see all the positive comments. You did a great job. Be over soon to get the ECU Flashed. 🏍️💥 Sean

That exhaust does not say Yoshimura. It says "Racing Spirit". It is a cheap chinese POS exhaust.

[@crispysmotorcycles]

Interesting Ron. We didn’t supply it so I can’t shed any light on it, but I know the customer paid a lot of money for it. It does say Yoshimura underneath “Racing Spirit” if you look closely at 7:03.
