What is a good hone?

[Ndog]

Hey all, I have collected quite a few special tools and one of the things im lacking is a hone.

Seeing how I have 7 2-strokes....I am thinking it would be a good thing to get.

My vehicles range from 80cc to 250cc....

What is a good hone to get to prep cylinders for new rings?

Thanks

you will likely need more than one hone

I've got a couple rigid hones.

As far as Flex Hones.......what diameter and grit would be good for the 250cc top end prep?

[nd4speed]

My flex hone for steel lined 250cc looks to be 3" and 240 grit I believe.

I don't think you would want to use a ball hone. Would'nt it hit the sides of the ports and damage them? I am looking for one also and found a real nice kit.

Its a KD and looks like it will work fine for 2-stroke apps. Luckily I can get them through Mac cheaper.

I haven't tried a ball hone, but if you get a std type cylinder hone with three stones you need to get the real long stones so they will bridge across the port openings. The short stones shown in the link will fall or tip into the port and chip the stones (from experience) . Not sure if that's an issue with the better ball hones or not.

Guys...I need to get this ordered ASAP bc im doing my rebuild next week. Should I not use the ball hone now? Im still wondering what grit to use too or do I use multiple stages?

With all the top end rebuilding constantly going on surely someone can steer me right haha.

one thing i never liked about bottle hones is when they start to wear after 3-4 uses they start to become inconsistant.

get a standard 3-point hone and youer good. and when the feet wear you can go buy more. for smaller bore engines, I use a brake cyclinder hone and for larger I use a small engine honer. both can be had at most auto parts stores for $12 average.

After reading about honing last night, im thinking maybe I shouldnt do it at all. The only reason the top end is getting done is bc of the lower end crank failure. It didnt have that many hours on it.

Scotchbrite pad seems good enough to roughen it up a bit for the rings to better seat.

Am I wrong or what?

These are the best hones for a 2stroke. If you use any other type of hone you will run the risk of getting your cylinder out of round do to the ports. These hones are rigid and will keep it perfect.

There is no place like hone. Dorothy from the Wizard of Oz. She was really not from Kansas.
