05 crank in a 01 motor???????

I have a blown motor that I am going to get rebuilt. My question is will a 05 gsxr 1000 crank fit into an 01 gsxr 1000 motor. Also what all cranks will fit into this motor and which will produce the most hp. Thanks in advance!

I doubt it. The 05 should be a shorter throw as well IIRC.

I think 01 through 04 were small bore long stroke and the K5 was the first big bore short stroke engine.

Re: 05 crank in a 01 motor???????

An 01-04 will physically fit as I understand it.

the pick up rotor is different on the end of the 03-04 cranks as the computer was better and the pick up was a bit better. Easy to make the 01-02 rotor fit onto a 03-04 crank though.

Have you priced getting the old crank fixed by Falicon?

Re: 05 crank in a 01 motor???????

Sorry for thread stealing, but we are talking about cranks here anyway so I might ask this here.

Is it good idea to get your existing crank lightened? Does the improvements justify to pull my bottom end apart? I'm getting top end work done, and started to think the crank lightening. If it makes it more rev happy and frees couple hp I see why not lighten and balance it, unless it makes reliability a concern.

Re: 05 crank in a 01 motor???????

No reliability concerns but very little gain for the money. Not worth pulling the bottom end apart just for that in my I know jack shit opinion.

see more gain from after market pistons.

Course if you pull the crank, you can delete the balancer at the same time. Very common.

What are you doing to the top end? Port and cams?

Sorry did not see that you have a 600. I don't believe they have balancers.

Re: 05 crank in a 01 motor???????

I have like three damaged journals and it would be cheaper to just buy a new one. Only one rod bearning went out but my mechanic said that other journals were damaged as well. Ape has an 05 1000 crank that is already lightend and balanced. I guess a customer didn't pay so their selling it.

Re: 05 crank in a 01 motor???????

how much, I am 99.9% sure they are interchangeable. I know a lot of guys use 01-02 cases and 05 guts and head to build big motors because the 01-02 cases have more meat around the pistons.

Re: 05 crank in a 01 motor???????

Did some asking and they will fit yes, only difference is the ignition pick up.

I wouldn't right off repair just yet, if you have three damaged journels that would be 350 to fix, which include heat and nitrade (think thats right) treating. Thats threw Marine.

Re: 05 crank in a 01 motor???????

Well I called and its like 250 for one journal 500 for two so I guessing its going to be like 750 for three and so on. Looking at the part numbers it looks like nothing other than 01/02 will do. Is there any proof that the 03/04 cranks will work for sure and if so where?

Call david at Marine Crankshaft, he charges 250 for first then 50 for each additional, that included heat treat.

Don't know were to find proof other then talking with other builders, the reason for differnt part numbers are the slines on the end for the ignition pick up.

Thats a hell of a deal when you think about it!! I knew it ran about 250 for repairing one journal, I didn't realize that it included nitriding & heat treating too!

I have several spare cranks in my "parts inventory". One of them has a heavily scored journal ($40 ezbay special). Another came out of a running motor, but has just a bit more wear & scoring than I'd like to see for a performance build. I could "get by" with it, maybe, but.... why risk it.

I've got at least one more GSXR1000 motor to build in the next year (probably another 1070), I might just use one of those cranks. I had planned on getting the crank polished / balanced / nitrided anyways.........

I like Marine's work, they did the work on the 4mm stroker crank in my 1K4 (1143cc now), recommended by RCS. It seems like Marine is one of those companies that gets a lot of business from "people in the know" but aren't widely known. Like R&D for transmissions....

Re: 05 crank in a 01 motor???????

Deffinatly, my 4mm stroker went back to him 4 times this summer, and he was always more then happy to work with me in getting if fixed and trust me, the second trip there (one after breaking two carrillo rods) the journels were nasty, came back looking brand new.

I aggree, ask almost any well known builder who is a great choice to send a crank to and marine is almost always one of the top ones, but outside of those guys they don't seem to be two widly known, at least in the bike world. Been toying with the idea of sending a very very bad diesel crank to him just to see if and how much to fix it.

If your not the sharpest tool in the shed, be the biggest f***ing hammer... may not be the cleanest cut, but it still gets the job done.

Do you really think he fixed that FUBAR'd crank?

If I were him, I would have opened the box, took one look at it and said FUCK THIS, I DONT NEED THIS SHIT IN MY LIFE and pulled a new one off the shelf and shipped that to you!

I think you're gonna need to do a DNA test on that crank

(I'm totally joking about all that. In all seriousness, if he fixed your crank he's damn good, and if he sent you a new one he's damn nice, so either way props to him)

Re: 05 crank in a 01 motor???????

All GSXR 1000 cranks are interchangable from years 01-08. There are differences in the oiling grooves cut in the cranks and the crank sensor pickup will need to be modified. Pretty easy to modify. I would put a newer crank '05 and up in the '01 because of the better oiling.

Marine does great work but, I would go ahead and buy a new one if the damage was that bad. Make sure to put in a new oil pump and clean the oil pickup.
