Cylinder Borring

[kasey200x]

I went to the shop yesterday with my cylinder to see how it looked. He told me it was at 66mm and he could just hone it out and put another new 66mm piston in it. We talked about doing that which would be 15 bucks, or getting it bored, which would be 40. Either way, he had to have the piston. This is something that was new to me. I thought you could send your cylinder off and get it bored, then order the piston. Was i really incorrect in assuming this? Also, i called back a second ago to double check on the piston i should get. The guy's wife answered and said i should go with the 66.5 and it will be 75 to bore.
So automatically i thought she was thinking it was a 2 stroke, or something needing that nikisel plaiting(No idea how to spell that) and she said that was and extra hundred. And it was definatly 75 bucks to bore my cylinder.
What's up with that? The guy told me 40 dollars. It's a family owned buisness. Maybe thats why. But money is to tight to be spending that on a bore right now. And i just sold my piston and cylinder because he quoted me 40 for the bore. Now i'm stuck.
Any ideas?

200x btw,
thanks

You should have just Honed it, You need to have the Cylinder & Piston in order for them to hone/bore.

If they do it with out it RUN !

[ezmoney1979]

You need the piston to size up before boring is the short answer- also different pistons (cast/forged) require different cylinder to piston clearances. It sounds like you are best off going up a size and having a fresh bore IMO.

Okay well i understand that i guess. So i'm still worried. If i do just get it honed, i still have to get a new piston. I dont' know what happend to the original. And i'm worried that just taking there word will get me screwed over. They only mic'd the top and bottom of the cylinder. Not the center.
Thanks for the reply.

Go somewhere else! Both cylinders I have had bored for the 200x were 40 bux straight up, bored and finished honed. The tri-zinger cylinder I used for my moped was 40 bux bored and honed. 40 Dollars seems to be the going rate everywhere around here to bore and hone a cylinder. I wouldn't have a cylinder bored and honed without having the piston there.

[kasey200x]

They are literally the only shop that will do atv cylinders in a hundred miles. I think i'm going to call him back, and tell him the position they have put me in. Maybe he will feel responseable for giving me a quote, that i tripple checked "So 40 bucks for the bore right" "Ya that right"

[Jammtee]

i would say 40 bucks is cheap. for me to get a bore, it will cost 110. and i am good friend with the atv repair shop owner, although they send the jug off for the work. the piston has to be ordered and there for the jug to be bored.

[kasey200x]

I talked to them about how they would do it. They have there own honing machine that he said he could bore with. He told me it would take about 30 minutes to hone it out, the longest part getting it clamped down. I also feel it would be much better to do a fresh bore. I was shocked when he said just hone it out. Espicially when he didn't mic the center to ensure it had constand wear patterns throughout the entire cylinder. Which i doubt it does. Either way, looks like it might be on hold for a while.

[Jammtee]

boring it would ensure that the jug in consistant. i personally wouldn't put a bike together without boring it. more power and longer life is the reason why choose to do it. and being you are ordering a piston any way order a high compression piston. i would go 10:1 because any higher you would have to run the good gas.

If the Bore is worn out enough...that its Close to the next size up but still under...(which i'm assuming it is) and not to far out of round..It can be rigid Honed out to the next oversize without a problem...Sometimes its Quicker and Cheaper..with the exact same results...The boring is done when its way out of round and a lot of material (sleeve) needs to be removed to make it round again and the proper size...It should Be Mic'd in 6-8 spots to Check..Most of the wear is Towards the top most often then not.. It is a good idea to have the piston you are going to run when its done,Cast and Forged pistons need different Wall/ring end gap clearance's to work properly. If however it is Right at 66mm..That is Not alot of room to work with..and chance's are it needs a bore..to get it perfect.

[kasey200x]

I was going to be purhcessing a 10:1 piston anyways. I originally planned on boring it out, when i showed up they said it only needed a hone. Again, only checking top and bottom. Not any interior spots. So i guess i'm going to have to save up some more.

[atc500x]

if it's a 4 stroke,I would suggest to go with an oversize,old cast cylinder is pprobably not perfect.If you take a new ring put it in the cylinder and check for clearance between cylinder wall and ring....pretty sure there is a clearance.Check the ring gap,habitually 0.004 for each 1 inch of bore is correct for ring gap.If you don't go with an oversize and the motor smoke after rebuilt will have to order another kit,so pay 40$ the first time is probably a good option.I have the boring machine and I charge 40$ for a bore...

[rdlsz24]

I agree just go with the next size overbore and be done with it. I think I paid around $50 for a bore and hone, and had to drop off the piston and cylinder at the same time. He wouldn't do it if I didn't.

Like i said, i would much rather do a bore. But money's tight right now. 500x, do you do a hone to finish up the bore? Are you open for buisness now? I may have to wait a couple weeks, but i need a decent priced bore and hone.

[NOS_350X]

get a 66.25 mm piston, and bore, you want to save the cylnder as much as you can. And that is the next size of piston they make.

Yes I do a hone finish the bore.I have no problem to do it for you,but since i'm in canada you will maybe pay more than the 50$ your local machin shop want with the shipping cost....let me know if I can help

[Toledo_Tommy]

You could hone it yourself , they sell a tool to hone bores yourself. My buddy brought his over and we did my banshee and then i just replaced the rings. Worked great , been running strong for the last year. When i get a cylinder bore done at my local shop it's 65 bucks and they want the piston before they will bore it. I would hone whenever i could to save on the cylinder , just my input. Good luck !

[kasey200x]

I actually looked that up. Well, i typed in honing boring tool on ebay, and all the came up was a brake cylinder honing tool. I wouldn't mind paying for a tool that i could use on my own. What do you use to power it? A drill? idea on price?
Got a link or a name?

[Toledo_Tommy]

Yes you use a drill , This is what we used on my cylinders. If you decide to use this you must be very very careful / http://www.autozone.com/autozone/accessories/OEM-Engine-Cylinder-Hone-Deglazer/_/N-25qiZ1z141ur?counter=0&filterByKeyWord=cylinder+hone+tool&fromString=search&itemIdentifier=555581_0_0_
Good luck

[kasey200x]

Good news, i found a whole top end off a xr200(yes cam included :) ) from the piston to the head for 100 bucks shipped. Cylinder has a brand new bore on it.
glad i didn't order the piston!

I would NEVER bore a cylinder with this tool,it's only for deglazing,not more.Since the since will not cover all the lenght of the cylinder wall,top and bottom of the sleeve will be honed 1 time in a pass,but the center 2 times.....if your cylinder is out of round before,it will be the same after....
A real honing tool worth about 500$ for a kit,and personnaly I only use it to finish the bore and adjust clearance,but the real way to bore is a real boring machine....this one is mine

Im not that far from you and Ive had a hard time trying to find someone to bore my cylinder also,what shop were you looking at and where are they?
thanks

[kasey200x]

It's called Rage Atv's . Its a racing shop down Highway 59 between spelendora and cleveland. It on Midway Road. They do really good work. if you got the pocket money. There is some places in houston, but thats an hour away for me. I'm not sure where cypress is. Also a place in conroe, which is a little closer to me, but still to far lol I think it's called Ted's or something.
Maybe when we get our bikes goin we can go ride!

i'm in arlington, Texas. There is a local shop that charges about $55 to bore and hone but you have to supply the piston. It's called 2-wheel world. if you are too far to come here, you can alwya ssend em the piston and jug and i'll haev them do the work and then I'll ship it back.

[oscarmayer]

if your cyclinder size is 75mm or larger the local shop I always talk about Endyn can do CNC boreing and honing on it. the smallest bar they have is 75mm so that's the smallest bore they can do. but if you are that ore larger, nothing is better than a CNC job..

Thanks,now that you mention them I think Ive heard of them.A friend of mine had some work done there and it cost him an arm and a leg but maybe thats the going rate.
What places in Houston? I'm right outside Houston city limits,hiway 290 and fm1960 area,but I drive to Kingwood for work.
