Rock Monster My Ride Posted July 26, 2014 So the stock service limit on piston clearance is .002 in. Does anyone know if that changes with the Cylinder Works 434 kit? If so what is it's service limit. Mine is currently .003 in with vertex 93.95mm piston and cw cylinder. Share this post Link to post Share on other sites
Noble Posted July 26, 2014 No, not according to the Suzuki manual. Set up new is .0012 to .0016 inch, Very tight for a big 4 stroke with a forged piston. Service limit is .005 inch. A CW kit is going to be set up with more clearance as new. Probably .002 to .003 inch. I would use the Suzuki service limit of .005 as a guide. Share this post Link to post Share on other sites
mickeydee Posted July 26, 2014 The last time I checked my piston to cylinder clearance it was .0023 or .05mm on my 434 bore Share this post Link to post Share on other sites
Rock Monster My Ride Posted July 26, 2014 Thanks that's all I needed to know. Now does anyone know where to find the rings only for the vertex 93.95 piston? I have checked their site and can only find stock bore on rings only. Share this post Link to post Share on other sites

Sorry for the old bump folks, but is this expressed as "12 ten thousands of an inch" if you were speaking to a machinist? "12 thousands" in machinist lingo would be 0.012 yes? 1 Share this post Link to post Share on other sites
Noble Posted May 14 Yes. .0012" is 12 ten thousands of an inch. Or sometimes 1.2 thousands. 12 thousands is .012". Obviously written is more concise than verbal expression of decimal fractions. Metric decimal fractions are written as zero point something as in 0.40mm. Where as inch decimal fractions do not use the zero in front of the decimal as in .005 inch. 0.005" is not wrong but as far as I know the preceding zero is not industry practice. I mention this because all to frequently conversion from/to inch metric the decimal is misplaced because of the added or in some cases missing zero. 1 2 Share this post Link to post Share on other sites

That seems so tight for piston to wall clearance from what I've been reading. I'm trying to get my head around the whole thing. Most of the specs I read are more like 0.012-0.015" for example. Suzuki to put their spec in ten thousands with a 5 ten thousands variance is odd to see for me. Thanks for the late night fast reply. Share this post Link to post Share on other sites
74jimbo Posted May 14 Um.. no......It is not a 10 thousands of an inch....THOUSANDTHS is correct. A machinist would know this though... but that TH at the end is important Share this post Link to post Share on other sites

A machinist would know this though... but that TH at the end is important There's an extra zero though. So I was wondering how you'd say it, 0.012 is simple, "Twelve thousands". 0.0012 I was unsure. How would you say that personally? 1.2 thou? Edited May 14 by Atolduso Share this post Link to post Share on other sites
74jimbo Posted May 14 There is not an extra 0.Once you start going to the right of the decimal point. There is no oneths.012 is 12 thousandthsThe first number to the right is tenths, the second number is hundredths, the third is thousandths, fourth would be ten thousandths, fifth would be hundred thousandths, etc Share this post Link to post Share on other sites

I'm asking about 0.0012. Different number. My question was just about how'd you say that to a machine shop. Edited May 14 by Atolduso Share this post Link to post Share on other sites

74jimbo Posted May 14 I thought that was determined but you said the above so I wasn't sure. I was using generic numbers in my posts. The numbers other people have posted in this thread are all over the place. Share this post Link to post Share on other sites

I'm really confused, you misread Nobles reply post I think, no one was saying 0.0012 was ten thousands of an inch. Noble said "12 ten thousands". Which is right as you are also saying.

ohiodrz400sm My Rides (2) Posted May 14 Most machinist would just say twelve tenths or 1.2 thou because it takes too long to say thousandths. Typically .xxxx" is spoken as X tenths. For example .0009" would be said as nine tenths. Go any smaller and they'll start speaking in microns. Working for a bearing manufacturer if I wanted to communicate a range of .0012"-.003" I would say the spec is 1.2 to 3 thousandths. 2 Share this post Link to post Share on other sites
jjktmrider My Rides (10) Posted May 14 (edited) Ya, I tend to say one thousandth and 2 tenths, may be a local terminology thing. If talking to lesser experienced guys I prefer to point out in separate sections, if not physically written the number .
