Now putting new set of rings in my 2001 SRX... Does anyone suggest Honing cylinders...some people say you shouldn't hone a srx cylinder...??? anyone know the facts on this one? :-)

FYI - Putting in different cylinders there in excellent condition thou..just curious how the rings will seat..

The best result would be to send to US Chrome or Millennium. They want $24.95 per cylinder for a diamond hone. Their equipment will provide for a straight and true hone. Just ask for a light hone. It won't really change the size but a tenth or two. Call them - they will actually answer the phone and any questions. ---mac---
 
What you are doing when you want to install new rings is simply deglazing the cylinder. You are not honing them out. Yes, you use a honing tool, but you are not really taking material away. Deglazing is all you can do to a nicasil cylinder.
 
Valin - I would agree that the goal would not be to increase cylinder size. However when you deglaze or hone in any way material is removed. If instead he uses a ball hone it does not provide as good a job. Ball hones follow the imperfections in the cylinder however they will deglaze. The diamond hone from a cylinder plating company is the very best and is straight and square. I have used an Aluminum Oxide ball hone when replacing rings. It worked OK. Since then I have used diamond honing and believe its a better choice. I guess it all depends on budget. Three cylinders times $25 plus shipping verses buying a ball hone.
 
Indeed you are taking material away every time you deglaze a cylinder, but it is very minimal when done properly. When deglazing, the goal is to essentially only induce new cross-hatching into the cylinder in order for the new rings to wear against, and effectively seat properly. I agree....ball hones are not very effective, and the job should be performed using a Sunnen or equivalent diamond honing tool.

EVerytime you re-ring do you glaze the cylinder ???

Yes. By deglazing, you are actually creating many rough edges in the cylinder walls for the new piston rings to wear against. If you do not deglaze, the new rings will not seat properly because the existing cylinder walls are smooth and shiny, thus leaving a lubricated area between the cylinder and rings, not allowing them to seat and form properly with the cylinder walls.
 
ball hones are scrap they dont cut evenly in a 2 stroke cyl., the balls flex in and bounce off the sides and edges of the exh ports and transfer ports and could chip the Nic plating,seen it done, you'll get a much better job with a 3 stone spring flex hone, you can adjust the tension of the stones and this is something any rookie builder can buy from a local auto parts store. Look for them in the 240-280 grits.

Nic is a hard hard plating very tough your not going to remove anything with a standard hone so rest assured your deglazing if anything..

i've honed i haven't honed i really didn't see any different either way they all ran good with good comp and leak down test when done and broke in.
 
I use wet sanding papper around 240 grit, seems to work!
I´ve got the tip from an local motorcycle engine builder.
 
I've known people who used 6-700 grit sand paper and some wd-40 or kerosene for lube and it seemed ok.I personally used a 3 stone hone with fine stones and ran it in and out 3-4 times with honing oil and it cleaned up nice.I haven't rode it yet since my rebuild, but it seems to run well on the stand in the garage.
