Probably I will be buying big lots of parts from a gen5, in order to convert my gen4 into the new gen5 electronics.
mechanically I will be getting a gen5

and all electronics.

I want to know if I need to change something in the transmission also?


Thanks

I'm guessing(hoping) you have a good reason for doing this. Not really sure exactly what gen5 parts your switching to aside from electronics. Wasn't sure what mechanically you're getting a gen5 means.

I would call Farrell Performance and ask Jason nicely since he is the only person, I know at least, that knows Kawasaki's inside and out.

I have a complete harness/ECU/dash etc that needs a home...has a Woolich flash with a u4.4 tune on it for a stock motor, full exhaust, MWR filter...201hp/86ftlbs

you need the following from a gen 5:

gauge cluster,
harness
ecu
IMU
throttle bodies
airbox
crankshaft position sensor
shift drum
shift sensor + adapter
plug ends for gen 5 fuel pump / or gen 4 harness end or a gen5 fuel pump
clutch lever sensor
left handle bar controls
non oem shift sensor to clear the frame - woolich shifter works great.
... maybe a few other things im forgetting at the moment/that i ignored due to racebike.

Otherwise it will run fine / great. I recommend also using a gen 5 header if you're on a stock header.

you cannot adapt gen 4 position sensor with gen 5 electronics. The gen 5 sensor is a potentiometer with a higher voltage range than the gen 4 switch produces. Also the gen4 position sensor is just a simple switch.

Install a gen5 shift drum and sensor is required.

This is madness. Sell your bike. Dont buy your mates stuff and buy a gen5. Then save yourself a massive amount of time and agro plus cash.
Ps noone seems to mention the gen5 cases having extra machining to clear the different gear sizes. Thats what a kawasaki technician told me

Just electronics? or everything listed above to get 6hp? I'm guessing almost everything above. ETV, IMU, Throttle Bodies, airbox? 2 degrees more advance.

I could see 6 hp with larger throttle bodies, STP gone, larger airbox, and an IMU controlling the TC better.

Very interesting for sure.

Well, its all required to get the electronics conversion, so yeah ;)

But i do also have a gen5 header on there, but i've always had a gen5 header so...

For sure the gen5 tbs and airbox improve power. Gen5 header improves midrange for sure as-well.

Gen 4 and 5 cam specs are the same. The head may have slightly improved flow / porting / casting and different rods/crank. but largely the motors appear to be the same / similar.

Now the RRs are drastically different head/cam/crank from both the non RR gen4 and gen5.

yes, the gen5 headers are better for midrange... not much but they are better.

the gen5 head uses same gasket but since gen 4 rods strech less, you cannot go crazy with gasket in gen5.

gen 5 cams are the kit cams of gen4 and use diferent timming.

I see in a dyno usually +10hp on top and more mid range in gen5...

mine has some tricks and get same top as gen 5 but mid range is not the same...

I had been referencing parts listed on which they offered for 2016 motors but did not update the description. I have my gen5 serv manual but did not bother to read there for specs. This motivates me more to buy the kit cams this winter.

k-raceparts.com - Kawasaki Race Parts lists all the below cams except the very bottom 2 which i believe are stock zx10rr cams.

As you all know me, I update 99% of the time.

my friend gave me for cheap a entire g5 engine, it started and you can hear a ticking noise.
airbox
throttles
ECU
wire harness.

stage 1
put the gen5 head in the gen4, I need sugestions with head gasket and timing of the cams, the head will be cleaned and lightly ported.

stage 2, gather all the correct parts to fix the gen5 engine, I alrready have a gen5 crank I got for cheap in ebay.

stage 3, gather all the gen5 electronics, to convert.

all sugestions apreciated.

by the way I have a non ABS harness for sale, I need a ABS harness.

Or sell the lot and buy a bike done. Its all good fun playing with engines but if it ever goes bang it could kill you. Plus also if you arnt hurt pysically it can cause lots of agro and stress. I used to do it with cars but after my 3rd engine went bang i completely gave up. It can be a depressing time when hours of work goes bang. Id personally just get the best engine that your money can buy. Most new bikes are pretty well tuned from the factory and just need the basics to get them up in power and still be reliable
