Can I file down .50 over rings?

I know... I know... but are .50 over rings anything but bigger, longer curved strips? I can get a deal on oversized rings.

Stock rings (in my experience) always seeem harder to find than oversize.

Ray had this one covered.

I was thinking that shortening the overall length of the rings by adjusting the endgap might allow .50 over rings to work in a stock bore. Times are tight and I'm adding 1/2 a quart every 150-200 miles on average lately. Pretty sure its the rings and not (just) the valve stem seals.


There is one lot of four sets of NOS GS750 .5 over rings on ebay right now for $25

http://cgi.ebay.com/ebaymotors/FOUR...s?hash=item19b3571684&_trksid=p4506.m20.l1116

Not actually sure if those are even for the 83-85 bikes but it would have been worth asking if I could have used them.

shorten the ends and compress a ring that makes an oval not a circle

I think this needed some emphasis it was not a stupid question you asked, but c'mon.!

you'd need a hammer to get them in there. and then where would you be.
a half millimeter is a mile in this area.
 
This is standard fare on old British stuff - but we're talking waaay different tolerances here so the guys above have got it right.
 
Are any of these opinions backed up by facts? I mean it doesn't sound like a good idea, but has anyone actually tried this and seen the results? Maybe it would work just fine.

Old skinflint me didn't listen and tried it years ago (750 Honda I think -being brought up on British bikes I thought it was a load of b*llsh*t). Wears the bores almost as quickly as pouring rocks through the plug hole.

The exception here I believe is that 1mm OS 850 rings fit a 1000 as they are the same (before anyone goes down that route will somebody back me up or tell me I'm wrong - I'm working from adled memory here:confused:)
 
Thanks, everyone, for your input. I ask my share of boneheaded questions and a few good ones too. One of these days someone (probably me) is going to figure out there is a search option and find out this info before they f'up their own bike.


Now when can I expect that $600 so I can go out and get my oversize pistions? ;)

i will send you a western union money order for 1100 dollars you keep the 600 dollars plus 200 for your troubles and send the rest back.


Kay?
 
i would think that rings make for a .050 over hole would not be round once the end gap was shortened and the ring compressed into a smaller than meant for hole.
meaning the rings would side load because they are not round anymore.
i say "hole" in the most loving way...
not refering to anyones better half ect...
trippivot says some of the things that i think but refuse to post.
he is my hero now and forever:o
 
The original question was for .50 over rings. This would be .50mm over or .0196" (nineteen and a half thousandths). Not .050" or fifty thousandths. Still at .0196" over that would amount to around .061" of filing off the end of the rings. Still would not produce even ring tension due to the out of round condition. Dar

i been meaning to ask...
did you guys run IDBA on a turbo suzuki many moons ago.
my memory may have failed me again...thought i'd ask.
 
Yes that would be myself as the builder/tuner/smart-ass/ect, and my friend Roger Franke owner/pilot. Twin City Racing Top Gas Turbo! Who am I speaking to? Man I miss the IDBA, those were the days! Dar

terry macintosh rode my top gas factory colored full fairing MSD 2 stepped 1100 katana(turbo GS) in top gas in 1992.
i mention 2 stepped because i believe there was only one other person 2 stepping a turbo at the time.
kicked a rod out in the water box(1st time run) in memphis..i think he only needed to qualify to be in the top ten that year.(didn't happen).
i'm local to terry m. and john pearson.
my names terry also from the dayton/cincy area.
things used to be fun..now they are what they are..
i still have the letter leigh-ann sent to everyone about closing the IDBA on its twentyseventh season of racing.
bummer.........
