How do the cylinders look and are you going to re-hone them.

 

[MTm7]

look at all your motor mounts.

the cylinders look great and i probaly will have them honed out. i never thought about looking at the motor mounts thanks for that.

Check your crank bearings and runout as well.

Make sure you take them to a shop that knows what they are doing i think you have to have a diamond hone for a nikalsil cylinder,and i just got a new engine mount for my pto side it was torn.

I did not know you could hone a nikasil cyl. Was I wrong?

Yes you can and many O dealers do it often and the manufactures have specs on how to do it. how do you thing the cross hatch gets in the NEW cyl when you get them? just check for scratches, flaking and pitting.

Personally, I always split the case and replace the crank seals when I do a top end. Lost one motor to a bad seal before and it's not gonna happen again. Gives you a chance to visually inspect your crank and bearings too.
