Adding compression

No Im not an engineer, started out to be one but I got out of it because they are dumb like you say. Phd's out there building things that dont have a clue what the difference is between a ball bearing and a roller bearing....

When I was talking about interference in terms of parts colliding you were talking about interference timing? I dont guess either of us were on the same page there but you said:

These are interference motors, meaning there is no clearance. They will hit.

...right after I asked the question about clearance. Seemed pretty cut and dried to me what you meant. I mean if we were singing from a different sheet of music that's fine but don't try to say I was dense for misunderstanding such a simple statement as that.

Interference timing included its still a question of clearance. Either the mod will work or it wont work. Youre telling me it will, that its a common off the shelf thing. All you had to do from the beginning was just tell me "no, you will not have to do any additional mods when changing to a thinner gasket" since thats explicitly what I asked in the first post. If I wanted to break my engine down to laser engrave my name on the top of the pistons it doesnt matter if its worth the time or money, its what I want to do. So thanks, like I already said, for trying to help out by telling me it was a waste of your time and money. To your credit you said too that its my bike, do what I want so thumbs up to you :thumbup for that

I respect you for what you seem to know its just silly how off the topic that all got. Davidhar on the other hand seems like he just wants to argue about things I never said. At least I learned from you that these were interference engines without knock sensors!

EDIT FOR Davidhar: Btw David, if you want to send me your pistons my company actually does offer custom laser engraving so I could put your name or your favorite ball team or whatever you like on there.

Does anyone know how much clearance there is stock between the open valves and the piston at TDC?

To your credit it does say a TDC, But with no way to know how much you DO know vs how much you THINK you know, The answer I gave was prudent and correct.

You spoke wrong, but I answered your question as best I could based on the question you gave.

You never really specifcially asked "can a head gasket be changed with no other mechanical changes"

You ran around your elbow to get to your asshole with a bunch of assumptions of measurements you have not taken, and making it quite clear with other statements and questions combined that you are way in over your head.

But even at that, I answered with as pertinent answers as I could without runnign with your assumptions which i refuse to do.


Again I say, you are in over your head. Again I say you claim to want to "get the most out of your 600" without "power adders" there is only a few ways to do it that fit that description "the most". You see, tossing a thinner head gasket at it does almost nothing... so it does not very well fit that bill now does it . So again I say, Go with one of three levels. Bolt on mods. Supersport build, superbike build. Anything in between does NOT fit the description of what you said you wanted in the first place.

Now if you have changed your mind, and just want to throw shit at your bike, go for it.

But then why the FUCK did you even ask, if you already act like you know the answers?

Haha! I like you Joe, you know I think before this is all over we're going to become good friends.

I actually did say exactly what you said I didnt say in the very first post just like I said I said a second ago:

Kydan said:

What I'd like to know is will using a thinner gasket cause interference between valves/piston/head and require further modification?

Now when you go back and check that I actually did say that and didnt edit it in know that when a machinist says the word "interference" he means it in the same sense as "interference fit" as in a press fit that holds itself together. I wasnt thinking about timing, rather I was thinking position, when I wrote about TDC but you know TDC is just that...timing, so really were coming at the same thing from different angles.

Just for information's sake, I am actually working on a list of upgrades, some minor, some major which as you mentioned before are trivial on their own but add to mean something together. The list is up to 11 things, fuel mapping, intake and exhaust are on that list. Like I mentioned already, I never said I was going to be done in one mod with a huge horsepower increase like with the gasket by itself. Anyway, the term "the most" is purely subjective. Apparently Im thinking efficiency for size and you're thinking dyno curves. Its fine either way.

Btw heres that gasket, a 12.8:1 vs 12.5stock. This is what I want so long as it doesnt mean that I have to use different pistons. http://www.yoshimura-rd.com/p-4309-cylinder-head-gasket.aspx

Kydan said:

Thats what Im saying. What kind of "precision" parts do you have anything to do with? What are your tolerances?

Click to expand...

Automotive specialty. Doesn't really matter though, what the company you work for makes still doesn't mean shit for your competencies or skills. Probably same dimensional tolerances as what is really used by the place you work - not the numbers you type in excel for all your graphs. And then I also deal with material specifications, rather than the purely dimensional hang up you have.

I am curious though, first you were a 'machinist', then I think it was mechanic, and now 'process specialist' - code name for the chart maker. And that's not all that you've been changing as you go. How long until BS and inconsistent stories come around to you getting butthurt?

I never said or suggested I did coatings, you inferred that.

Really? Right here.

Kydan said:

Im a machinist with access to any type of equipment I'd need, and if I wanted to I could bore the cylinders, deck the head for added compression etc.

Click to expand...

Can't bore the cylinders without replating. I didn't infer anything - you said you had access to the equipment and could do it yourself.

Actually I dont have to think about that, I know I can [build a better billet block than Suzuki] but its more work to me than its worth to do that.

Ill be making my own exhaust from headers to muffler.

Cocky, aren't we? And full of shit.

Kydan said:

Its not more work than its worth to do the two things I asked about though which might take me one evening to port/polish(if needed) and one evening for putting it back together.

Go for it, make it run worse all you want. KWS and anyone else worth their salt does hundreds of flow bench tests on port variants to figure out what works best. If you think a dremel with no idea how it flows is just as good, make sure to get a dyno before and after to post up. :lol The results would be great to see.

Still true that just a head gasket will not make a worth it difference. With ported heads, still not really worth it. Might as well do the cams while you're in there. But then you're up to a level two build from KWS or such, and pro engine builders can't know better than the chart maker. :bitchslap
