Cylinder stud removal

Post by komaiaboyz »

Hello, Does anyone have any advice on removing the studs from the cylinder head? Thanks. Also anyone have a RH KIPS for a 1994 KDX 200? Thanks

Thread on two nut on the stud... snug them against each other and then turn the stud out with the bottom nut.

And ... not me.

I googled it and found this: Anyway, you just take two of the head nuts, thread one on upside down, the other right side up so the flanges are back to back. Tighten them together so they won't slip and then turn the bottom nut counter-clockwise. This will break the stud loose and then you can unscrew it by hand or just finish unscrewing it with a wrench.

Jam-nut technique works on any threaded in stud. Better than vice grips even! :mrgreen:

I've had some studs on old Enduro restorations that were a bit more challenging.
Long term application of Kroil, aluminum jaws in a vice, and application of some heat (last resort) did the trick. The aluminum jaws did not damage the exposed studs.
Hopefully, the jam nuts will work and you won't have to go to more drastic measures.
Just remember to run a thread chaser on the studs and the cylinder threads before reassembly. Tap and die would be a second choice if you don't have a thread chaser.

I have seen studs so stuck that the jam-nut would start twisting a hardened stud like a twizzler (not on a bike). A good trick is to 'lap' the jam nuts so when tight the hexes line up...Then hit em with an impact gun. Barryadam those are all good tips.
