i think the 1000 crank will work if you use 1000 rods. rod journal is smaller. the zrx 11 will not work, clutch drive gear is different than the zx11 and will not work with the clutch. you can use the zrx11 crank but you will need to use the zrx clutch assembly. i have a brand new zx11 crank balanced byfalicon for $500. i might also have a used one,i will check.

if you get a welded crank i have used them in the past just make shure they are nitrited and i also would have it cryo-treated. the formula d car that the shop i work for has a welded offset ground crank in it and it makes 500 hp to the ground and 9000 rpm has never had a problem.

thanks for the info

also...ninjazx11...so thats a new crank(never repaired) and balanced....thats a good price....i was trying to find a little cheaper way to fix,since im out of consistent work,i think marine quated 350 to repair mine,including nitride treatment....of course ide rather have a new one...so the 1000 crank and rods work....thats good to know.i did see a rebuilt crank on ebay fro0m a guy in illinois....but i doubt its nitride treated.....but im not sure.

if you still have it,might save up fo9r the new one

im interested in a used one zx11....as long as it hasnt been repaired....and good shape....and that would be a good price......if i had to get mine repaired...then i want the nitrite treated ones....it seems the only ones that do that treatment is ape and marine...but im not sure...i almost bought one of ebay guy from ill.....but in his description....he doesnt say it is.

let me know zx11 if you have one and if its still stock...and never been repaired.....thanks alot....the reason i dont want one thats been repaired....is cause i think if i should get repaired one.....i should just send mine off

really looking forward to the spring....and the whole riding year : )

if you want or need one repaired call castillos crankshaft (714) 523-0321 they do nitriting and welding and trust me i am a very picky machinist and the things that he has welded for the shop i almost couldn't tell that it had been repaired.
