@171apples171 - Yes we do, even though it isn't listed in our specs. It depends on your bore size. Your KZ should be around 72mm. Please double check and refer to the following part list. 68-70mm hone part # is 1284240005, 71-73mm is 1284240016, 74-76mm is 1284240006.
@ch0l0sk8r - it depends how the cylinder looks. Honing puts fresh cross-hatch marks in the cylinder which helps seat the rings and keep the cyliner walls lubricated properly.
@andre1995ish - you want to take the glaze out and have the light scratches from the hone. This will help the new rings seat and allow the cylinder wall to hold lubrication better. If nothing else, use a scotchbright pad to lightly scuff it up (cross-hatch like the hone leaves).
@crazygondo113 - Not if it is done right. You want to use a hone like the "Flex-hone" that barely scratches the surface. The intent is to "deglaze" and put the crosshatch marks in the cylinder, not to remove any material from the bore.
@razed1022 - I don't know about airplanes, but OE nikasil plated cylinders (and steel cylinders) come honed from the factory. The factorys also recomend light honing to remove any polished spots.
@Browndemolitia - The hone won't take off "shavings", but tiny gritty particles from the hone certainly could fall in ports (2-strokes). That is why you wash it out when you are done.
@ImTrickeh - a hone will take out real light scratches, but nothing significant. The goal is to just remove the glazing. you will need a bore (if the sleeve is borable).
@polishcuz - It is important your cylinder has good cross-hatch scratches so the rings seat properly. If your cyclinder looks a lttler worn with polished spots or glazing, then yes the hone is important. Refer to your manual for inspection and hone instructions.
@jshepard74 - unless it is a very light scratch, you need to have the cylinder bored or re-coated (depending on the type of cylinder you have). LA Sleeve is a good place to send your cylinder.
@CR125MANIAC - if it is wearing out the rings that fast, I would suspect it is scored more than "ever so slightly". Either way, you could try a hone; if that won't work, you need a new sleeve or new nikasil plating.
Obviously since the shaft is made of two wires twisted together you can't get it perfectly straight in the drill so it will wobble a little but just try and get it as straight as you can. Also make sure the shaft is straight and isn't bent at all.
@redrider187x - any shop that bores cyclinders should know what they are doing. i am sure they will hone it. i hope you are sending the new pistons too. The cylinder has to be bored to the piston. If the shop doesn't know that, you should send it somewhere else.
@greenmonster687 - 320 silicone carbide. Aluminum oxide works great too on nikasil. i worked directly with the manufacturer to get the best one for motorcycles and atv's, and the 320 silicone carbide is what they suggested.
You'll want to follow the recommendations of the cylinder/rings manufacturer. But for deglazing a cylinder, you'll usually want around 320 grit. Hope that helps!
i was using a flex hone to hone a 2stroke cylinder n noticed the hone was eating away the area around the ports more then the rest of the cylinder,it actualy made an indentaion between the ports,why would this be? thank u for ur help
Guzman3605 When you hone a cylinder the only thing it's doing is removing the "glaze" from the cylinder. This isn't making the bore size any bigger so no you wouldn't need a bigger piston. The goal when honing a cylinder is to prepare it for a new piston and rings so when you do this it allows the rings to seat more easily to the cylinder wall. If you don't hone the cylinder before installing a new set of rings, it's possible that if it's glazed over the rings won't be able to seat and you will get blowby
Wasn't honing done originaly because old cylinders and rings were cast iron and wouldn't seat? With the metals used in rings & cylinders today wouldnt honing just cause unnecessary wear on cyl wall? reason I ask is I use rotax two strokes on my light aircraft, when I get cylinders back from A&P mechanic they are mirror like smooth w/out a single scratch. My compression stays around 140-145.
Hey I have one more question, it is when I don't know size of cylinder so I am going to take the cylinder to to shop so they measure my cylinder, ok. Should I hone the cylinder before measure, honing doesn't make big difference in size of piston or does it ?
Sweet! That would be awesome! I have a Cr500 and Kx250, and both need a rebuild I think. haha Thanks a bunch! Your videos are very well done and extremely helpful! Keep up the good work!
I would if you're already in there. You can also look for any cross hatchings on the cylinder wall.. if you don't see any or if it has any glazing then i would recommend honing the cylinders.
@razed1022 - My question is why use warm water to clean the cylinder out of honing oil when oil and water don't get along? Why not use mineral spirits or parts washer solution to cut threw the oil better ? Thanks
@RockyMountainATVMC Im sending the cylinders to the same shop that im Buying my piston kit from so there gonna just tell me what size pistons there sending after they Bore it. Thanks for the quick reply and Your video's are very informative. They have helped me out a TON! Thanks again!
how do you get the thing in the drill straight?? i keep trying to put it in my drill as straight as possible but it keeps wobbling every time. at first i throught it was just the drill so i tried the other one and same thing
For the 2003 CRF450R part # 1284240010 - Flex-Hone Cylinder Ball-Hone 96-105mm would be the correct hone and with as little as the hone is ran through the cylinder it's not going to change your bore size at all.
hey guys i have a 2002 kx 125 my cylinder is ever so slightly scored on one side and it wears my rings down within 2 hours of me breakin it in with new rings n then wont run untill i replace with new rings is there anyway i can resolve this issue without having to fork out for a resleeve or bore thanks ben
Hi I have an important question, Im sending my atv Cylinders out to have them Bored then they are going to return them to me so i can put a new Piston Kit in. They didnt say anything about Honing the cylinders after boring them? should i ask them to Hone them too? I thought once they bored my cylinders and sent them back with a Piston kit i would be good to go for installation? I appreciate your time.
@rockymountainatvmc hey say if i wanted to rebuild my kx250 topend would i need to hone it , what if i just needed new rings what does honeing do thanks,
do you need to hone a cylinder if its brand new? with brand new piston? or is there anything you have to do to prepare brand new cylinders? doing a cylinder/piston/head replacement on a ktm 450
@RockyMountainATVMC Have a question I am rebuilding my 03 banshee I would like to bore it 30 over but it worry's me that if I do that it would create more probloms for me like (Over heating) (Faster clutch wear)and trans) And also wondering if I will have to get an oversized head for the new bore I would really like to upgrade the power I just want to know how to do it properly without causing probloms
Yes, you'll want to hone your cylinder when you're doing a top end on your bike. Most pistons will come with instructions on how they want you to prepare your cylinder before your top end.
Hi there! I got a question. When u apply the light coat of oil at the end of honing your cylinder, do you wipe off the oil or leave it there? Thanks for your great videos!
I want to save some money and re hone my cylinder myself. I have a yammy warrior 350 and I see you sell vehicle specific flex hones but my cylinder is bored bigger than stock should i still go with the warrior flex hone? And also is it required to get new rings? My piston shows no damage. And my ring end gaps are in spec.
Yay for the flex hone! :D Thanks for the vid. And I have a question. Have you thought about doing a video on rear shock service/rebuilds, or would that be too dangerous a task for the home mechanic? The Clymers manuals don't seem too keen in helping with that, and Information on how to do that would be extremely helpful! Thanks!
I just bought a 3-3/4” flex hone for my wr450f. Is it true that i would be doing more harm than good? I only plan on rotating it in the cylinder for about 10-15 seconds. Thanks! Im nervous to do it but also know i need to create more cross hatch
If you follow these directions and don't overdo it, there's no reason you should cause any damage to your cylinder. It does seem like a daunting task but just take your time and use a smooth, fluid motion and you'll be set!
Sweet. Some people have told me to use a scotch brite, i’d rather just use the flex hone. Have you ever scotch brited a cylinder to de-glaze and put a cross hatch back into it?
@RockyMountainATVMC i have a kawasaki D tracker 300cc and the engine is stack. The problem is that the engine worked a lot of time with out oil... Will flexhone help me rebuild the engine? or do i have to sent it to a workshop for repair? If so where can i buy flexhone from? i live in Europe-Greece!
I am doing top ends on a 2000 rm125 and 2005 rm85. Both ran O.K. I found problems with power valves/resolved. Jugs/pistons were great. 125 WEAK compression. My question is do I deglaze nikasil? I've heard don't because the rings don't seat, like old school smokers with cast iron jugs. I just want a yes/no answer. And maybe a logical reason. Who knows, maybe this will help low budget do-it-yourself-ers, like me
Yes, it's always a good idea to hone any cylinder before replacing the piston. This helps the new rings seat properly and allows the cylinder wall to retain lubrication better. Even 2 stroke jugs benefit from being honed. As the video shows you simply run it through the cylinder 5 or 10 times to get that 45 degree crosshatch and you're good to go!
Depends on how deep the markings are? I would say no. Generally the ball hone is simply used to deglaze the cylinder walls and apply new cross hatches.
Rocky Mountain ATV MC wait can you check out my forum on thumper talk. It has more detail about the problem and I found something really interesting about it. Here's the link www.thumpertalk.com/index.php?/topic/1197885-1993-Suzuki-rm125-rebuild-help 1993 Suzuki rm125 rebuild help
I would recommend having a shop take a look at it. From your pictures it looks to be like having it re-bored and plated would be the best option and get it fixed right. A hone isn't going to fix the scarring on the cylinder. Yes, the bike might run otherwise but fixing it the right way is going to help all of your new parts last longer.
+Rocky Mountain ATV MC I thought the hone would remove the excess metal on the cylinder and i think that the metal is from the pistion, from the looks of it, it looks like the aluminum from the pistion melted on the head some how and caused the piston to get damaged way more and i think the hone can easily remove that aluminum if it is from the pistion
That's just going to depend on if it's the correct size for your cylinder or not. You'll also want to check the instructions of that specific hone because they may be different from that of the flex hones.
@171apples171 - Yes we do, even though it isn't listed in our specs. It depends on your bore size. Your KZ should be around 72mm. Please double check and refer to the following part list. 68-70mm hone part # is 1284240005, 71-73mm is 1284240016, 74-76mm is 1284240006.
@ch0l0sk8r - it depends how the cylinder looks. Honing puts fresh cross-hatch marks in the cylinder which helps seat the rings and keep the cyliner walls lubricated properly.
@motabikeboy - it is a cylinder from a KLR650 (fourstroke). It is somewhere around a 90mm bore.
These can be used on cylinders with ports however you want to be sure and run it through slow making sure you have plenty of hone oil.
@andre1995ish - you want to take the glaze out and have the light scratches from the hone. This will help the new rings seat and allow the cylinder wall to hold lubrication better. If nothing else, use a scotchbright pad to lightly scuff it up (cross-hatch like the hone leaves).
@PuffBongsAllDay - are you getting fuel? Spark? Are you sure you have the piston in the right way? i would double check everything.
@crazygondo113 - Not if it is done right. You want to use a hone like the "Flex-hone" that barely scratches the surface. The intent is to "deglaze" and put the crosshatch marks in the cylinder, not to remove any material from the bore.
@razed1022 - I don't know about airplanes, but OE nikasil plated cylinders (and steel cylinders) come honed from the factory. The factorys also recomend light honing to remove any polished spots.
Sweet! Glad to hear it worked out for you
@GrandDanois - the manufacturer recomends 320 for both, which is what we stock.
@Browndemolitia - The hone won't take off "shavings", but tiny gritty particles from the hone certainly could fall in ports (2-strokes). That is why you wash it out when you are done.
Will it take out a little scar in the cylinder because mine has a little scar
@ImTrickeh - a hone will take out real light scratches, but nothing significant. The goal is to just remove the glazing. you will need a bore (if the sleeve is borable).
@jamie123dog - you can certainly do that too (warm water with dish soap will clean out the hone oil as well).
@polishcuz - It is important your cylinder has good cross-hatch scratches so the rings seat properly. If your cyclinder looks a lttler worn with polished spots or glazing, then yes the hone is important. Refer to your manual for inspection and hone instructions.
@braaup - it depends on the bike (bore size). Check our website. use kyword search "flex hone".
@Xx11HaloGuy11xX - it is a special oil for honing. It is thicker than WD40.
@1993TMAXX - Thanks. i will usually wipe it off and re-apply some fresh WD-40 before installing the cylinder.
@jshepard74 - unless it is a very light scratch, you need to have the cylinder bored or re-coated (depending on the type of cylinder you have). LA Sleeve is a good place to send your cylinder.
Nice do they have one for a Harley 1200
@CR125MANIAC - if it is wearing out the rings that fast, I would suspect it is scored more than "ever so slightly". Either way, you could try a hone; if that won't work, you need a new sleeve or new nikasil plating.
- yes. we only offer one grit. It will work great.
@Excomunicater - yes. One of these days I will get around to doing it.
Obviously since the shaft is made of two wires twisted together you can't get it perfectly straight in the drill so it will wobble a little but just try and get it as straight as you can. Also make sure the shaft is straight and isn't bent at all.
Thanks for the straight-forward video, BUT that did not look like a 45 deg. crosshatch, much shallower than that?
thanx. i got it in as straight as possible and it honed the cylinder good so thats good. and it wasnt bent at all i checked. it was brand new.
@Bmac2812 - I supose it depends on the material used. Nikasil - yes.
Yeah we use WD-40 but any rust/ moisture prevention product would work
@TrollMaster300 That's just going to depend on the shop.
So I thought your never supposed to hone nikasil unless it’s a diamond hone?
@redrider187x - any shop that bores cyclinders should know what they are doing. i am sure they will hone it. i hope you are sending the new pistons too. The cylinder has to be bored to the piston. If the shop doesn't know that, you should send it somewhere else.
Is it ok to hone a cylinder thats nicasil plated? wouldnt that remove the coating and make the cylinder bad?
@deerman1212 - what is your bore size?
@bridgemaniii - the 320 grit we sell is perfect.
@greenmonster687 - 320 silicone carbide. Aluminum oxide works great too on nikasil. i worked directly with the manufacturer to get the best one for motorcycles and atv's, and the 320 silicone carbide is what they suggested.
@razed1022 they could be chrome plated cyls. they do not require glazebreaking
@mcmailo - no it does not. If you ran the hone long enough in there it could.
@563873 - the 52-54 is bigger in size than a 54. Go with the 52-54.
@MrNik1001 - Apocalypse possibly, but most likely the cold water won't break down the honing oil as easy:)
the hone won't change the bore size unless it it way over used. no worries.
@qwikyking - a new cylinder will already be honed and ready to go.
What grit do you recommend for deglazing?
You'll want to follow the recommendations of the cylinder/rings manufacturer. But for deglazing a cylinder, you'll usually want around 320 grit.
Hope that helps!

I would if you're already in there. You can also look for any cross hatchings on the cylinder wall.. if you don't see any or if it has any glazing then i would recommend honing the cylinders.
i have a 65 and the cylinder sleeve has deep scratches, would this work or would i have to get a bigger piston or a new sleeve?
Those are not recommended for nikasil plated cylinders. I would recommend investing in one of these Flex Hones.
