Use the OEM CR9E,you are gaining zero performance and throwing money away for nothing.
Verify the coil is firing on that cylinder,if it is...then see below

If the plug looks as described,consider doing a compression or leak-down test on that cylinder.

 

[Louis Chader]

Ok I'll do that tonight ..... Honestly didn't even know I was buying a "performance" plug at first..... I'll update soon!!

 

[Louis Chader]

Any idea how much psi those cylinders should hold?

 

[oldgixxer]

You'll have to source a FSM and verify the numbers or maybe one of our members knows off the top of their head,I don't know what they should be....but you can check all 4cyls and they should all be within 5-10% of one another. So if 3 cyls are between 140-150psi and one is 110 then you know whats up.

750 motor swap into my 08 gsxr 600

So i blew my 08 600 motor (first year with mode selector) im thinking about dropping a 750 gsxr motor into it. But i would like to know what all components i will need including parts from my gsxr 600 and for the 750. Also, what is the min/max year of the 750 motor i can put into my frame? Ive heard that 06-09 750 motor will drop into my 08 600 with the addition of needing the throttle bodies, ecu, and air box? Is this correct? Id appreciate any feedback, new to the site also!

I have a yoshimura edition gsxr 600 k5.
Opened it up to check the condition after buying it.
Does anyone know if it’s factory set that the timing is different.

The timing mark nr 1 doesn’t line up with tdc or the markings. Also, the pins between 2 and 3 should be 12, according to the manual.
However it’s on pin 11.

Like the full on Yoshimura worked over bike? I would think that the Yosh bike would have their adjustable cams and those are obviously stock. It looks like you're a tooth of to me, but without tech data on the Yosh model (and without actual confirmation of your's being a yosh) I can't recommend adjusting it.

Got pics of the entire bike? If it's a Yosh, it'll be pretty obvious.

It’s Yoshimura branded as far as I know. It got the full exhaust and yoshimura markings on the foot steps too.

So I should put everything back to as the manual says?
The valve clearance are all in spec though.

That's a stock GSXR with some Yoshimura bolt on parts. The Yosh factory bike has a very unique body. You need to fix your cam timing. Inspect the crank position to see if the exhaust cam is a tooth behind, or the intake is a tooth ahead.

Thanks a lot!
Crank doesn’t line up. So I think I need to check valves then.
It drove fine until it began to rattle. And I thought it would be the cct. But that seems a bit early at 18k km.
The engine picture above is like that when the markings on the clutch case and crank is lined up.

 

[TheGeek]

The previous CCT issues don't apply to the newer bikes, but everyone seems not understand that. It's possible the previous owner screwed with it and hopped the chain. There's an inspection plug on the right side of the bike on the crank cover. Remove it and turn the engine clockwise until the mark there lines up. See where your cams are. If nothing lines up, rotate one full revolution. Then adjust your cam timing accordingly. To do that, you'll have to pull the right cam cap and CCT, so you'll have an opportunity to inspect it.

 

[Cdvl]

Yes. Thanks. The timing mark on the cover is lined up. The cams definitely jumped then. Because the 1 and 2 mark on the exhaust cam does not line up with the cilinderhead vertically and horizontally.

I’ll put the cams back as the manual say and start it up to check how it’s running.

Thank you for your help and patience.

Trying to figure out what number I should shoot for to degree my cams 385 intake/ 340 exhaust
Also am I going to run into any problems using high comp pistons im not sure if I need to use the 10.1:1 comp or 13.8:1, stock bore stock stroke and will I have to use different tappets for the new cams help please

 

[temporarykiwi]

Hi, what model gixxer do you have ?, id say the 10:1 comp pistons will be for those turbo fans, the 13.8:1 set will be for use with high octane fuel, though i beleive the pump gas you get in usa is of a superior quality than here in nz, webb cams / schnitz racing can probably suggest the best lobe center timing for their cams, i have tried tim radleys 110/106 settings for k8 std cams with success, kerp us posted

 

[AI1Auto]

will the motor out of a 01 1000 fit inside of a 01 750 frame?

Yes, but not without some modifications to the frame mounts. As long as you are a good welder, it can be done pretty easily. I stuffed a K2 1000 motor into a K3 600 frame a bunch of years ago, so yes, it can be done.

Hey, done a lot of searching, but havent been able to find any solid info (realise i can contact carrillo, just thought this might be a better source of information for specifics!).. have a k2 1000, previously run squish at 0.65mm and 13k rpm rev limit with zero problems (stock bore, high comp wiseco pistons).. now building a new motor with carillo rods and want to/thinking about tightening up the squish a touch more due to less rod stretch.. just wondering how tight would be too tight (block is decked 0.1mm so with a 0.45mm gasket would be at 0.55mm squish which is obviously tight on stock internals) or if there will even be a significant difference vs the stock rods?
