You could find out the factory specs and check them for stretch.
If youre going to change rod bolts leave the rod bolted to the crank and replace/torque them one at a time to make sure things stay aligned.
Might as well check the bearings at the same time.

Full sweep of every component in the bottom end to make sure it is spec.
I have purchased a donor bottom end with only 15k Km. That go torn down last weekend and I took the con rods off, I just need to go through and spec it all out them decide when to tear down my current motor.

Thats why I say to leave the rods bolted to the crank and use it as a mandrel,then just change them one at a time while leaving other bolt torqued.DFIGPZ wrote: You do know that if you replace connecting rod bolts you must resize the rods after install ???
I dont imagine hes going to be winding this little bike enough to hurt it.

If the bolts are not a one time use item I wont replace them. The FSM hasn't mentioned replacing them.
Kinda confused by all this.
If I don't change the bolts and just want to check bearing clearance. When I am done can I just re torque and good to go, or is their more to it than that?

There is nothing to "resize" whether using new bolts or not.

I remember Lorcan runs turbo rods in his 750 and are reworked from the factory but not sure what is done to em.
I also remember (maybe Yosh??) or maybe just Cycle world talking of a big name (racing team) replacing theirs with chevy small block bolts as they are close but need just a little machining ...... this of course would be nuts and just relaying what I read.

Pretty much what my Service manual said for the rods on a Zg 1400 motor. It said to use new rod bolts, check the strech and measure bearing clearence with plastic gauge. Absolutly nothing about resizing the big end of the rod.
