200x Cylinder Hone

[mayhem17]

So I'm needing to hone my cylinder on my 200x. Got my piston in today, but none of the local stores had the correct hone size I need. I'm looking to pick one up on Amazon as they have a guaranteed free 2 day prime shipping for most of what I need. Does anyone have any good suggestions for me? The ones that I've found that have any reviews have mixed reviews. Most of the bad just being about the stones breaking. This will be the first time that I've done this, but I've seen it done many times, and never seen one break personally. Is it probably just the operator doing something wrong and then giving bad reviews? Any help appreciated.

He is the type of hone I use

I know many other people use them too.

I don't know if they have them on amazon.

Use a ball hone....10x better

This will work.

Well, I need to use the bladed style hone for my application as I actually need to remove some material from the cylinder. Going up to a 65.5mm diameter. Right now it sits at 65.2. Won't take much, but the ball style is more for a finish.

Well if you need to remove material I would get it bored to the next size. I wouldn't trust a hone to do that, but to each his own.

This was actually the recommendation from the local machine shop. They were just going to hone it also for that small of an increase in diameter.
And the fact that where I'm at, none of the machine shops will bore small engines.

Please don't try to bore a cylinder with a hone, I have seen this attempted a few times with poor results.

Also find a new machine shop or go to a motorcycle shop that has the correct equipment

Send it and the piston to m&r machine shop in greencastle Indiana. Jay is an amazing machinist with top quality tools. He has done 2 of mine for me. $75 well spent.

As stated. Trying to have this done before the weekend. I have 4 more cylinders also if this doesn't work, although it will. Have seen it done many times. Closest shop that can do it is over an hour away from me. I work 12 hour days on the weekdays, so very hard for me to get it there in the time frame needed.

a ball style is nit a hone, it is a deglazer.

Unfortunately if they told you that it is perfectly fine to hone your cylinder out .3 mm with a 3 blade hand held hone, they are incredibly irresponsible.

They were just going to hone it also for that small of an increase in diameter.

If they were going to hone out any worn cylinder with a 3 blade hand held hone they are either gods or they are incompetent . . I am far more inclined to think, or at least hope, that they meant they were going to use a power hone which is a very, expensive machine.

Not to be a Richard Cranium, but guys come here to ask advice from members of this board. Our vastly experienced members give good solid advice based on years of experience that started out with the same types of scenarios you presented: I need it done now, I've never done it, but I watched someone a couple/many times. All of us have learned thru trial and error that being cheap, cutting corners and being in a hurry don't pay off in the long run.

And the fact that where I'm at, none of the machine shops will bore small engines.

This statement makes no sense. "This is what they said they'd do, but no one around here does small engines."

.3mm is about .011. That's a lot of material to hone out unless you have an assortment of hones ranging from coarse to fine.

What are you using to measure your bore? Measuring just the top and bottom of your bore doesn't assure that your bore is straight.

Do you know the piston to cylinder bore clearance specs?

I have 4 more cylinders also if this doesn't work, although it will. Have seen it done many times.

It is simply impossible to properly true a cylinder with a hand held hone . . It will never happen in anyone's lifetime guaranteed . . Just because you have seen cylinders honed out to the next size with a 3 blade hand held hone, it does not mean they were true . . If your bore is not nearly perfectly true, your rings will never fully seat properly . . They need a consistently true cylinder from top top bottom to fully seal and there ain't one single person here that will yell you anything different.

This is not to say that an engine will not physically run if the bore isn't true, but it means that compression WILL will be leaking past the rings if it isn't true . . The more untrue is is, the more it will leak, and it tales very little out of round to cause a significant compression leak.

Sure you can do it this way so you can ride this weekend but at least you know the downfalls and can make a more informed decision . . Also, once those rings are run on an untrue bore, they will likely not properly seal on a true one so if you do end redoing the top end after this, i would use a new set of rings.

Thank you for the sound advise in this post. This is what I was looking for. I am looking for a somewhat quick fix for the weekend, hence my other post about using the cheap piston for the moment. I have another complete engine that I'm also redoing for this bike from the bottom up. Looking to be into this spare engine for as little as possible in the shortest amount of time as I am trikeless right now without it going.

To the comment about the machine shop making no sense, they do not have the equipment for small engine boring, but if they did, that they would hone the cylinder for that small of a difference. I live in an oilfield town, so the 3 machine shops that are here work with large equipment / vehicles only basically. The guy I spoke with is the owner of the business and used to do small engines, but there wasn't a demand for it here, and sold his equipment years ago. I also called the machine shop in my old town that did service small engines, and he told me the same thing if I'm only going to the next size overbore.

Another question to the comment you made (Barnett468) in regards to being true. I am trying to find the correct size hone with at least a 4 inch bar. The cylinder height is right at 4.5 inches give or take. Would this help in resolving that issue?
