x2 Drive shafts question

[Jayski]

The later x2 drive shaft was a larger diameter than the earlier one right? Is it necessary to run a later heaver shaft behind a 750 donk. or do you think I will get away with the lighter one (earler one)?

i wouldnt say it is nessary to run the lata one if you havent got one , ive been running a small dia one for a couple off years now on my 800, then again i did snap one when i was only useing a 650 go figure

mm yeah well my larger one was shagged out, so i managed to pick up an early type thats was in great nick.. But yeah ealry type.. anyone else run power through the small shaft?

so it prob doesn't really matter? bit lighter, maybe flex alittle more, but should snap.

[w-nut]

you should be pretty good , im running a sxr engine in mine and havent had any problems for the last 3 years

I have never snapped a driveshaft - the later shafts are larger diameter indeed, provided your driveshaft is straight and serviceable, I'd run it.

I have one of each. I wouldn't sweat it personally either way. I flipped out the first time I saw the early version. I bought an X2 to part out. Well I had all post larger X2's and 650 SX berfore that. So I had never seen a smaller one. Here I thought I had an aftermarket driveshaft. Nope, I just thought wrong... lol
