Can anyone find me an 86 200X 11:1 piston kit?? 12:1?? GOT ONE??

[Dirtcrasher]

I sent an email to Arias, no response yet, not sure if they make them.

They responded - 500$ for 2 of them

Some of you guys are GREAT at finding stuff.....

LAST POST IS EDITED....

Looking for a WISECO 12:1 now, just not a 120$ Dennis Kirk one

Why don't you go with the 10.5 to 1 and have the head shaved 2 thousands of an inch?

[SWIGIN]

.002 wont do anything

what i did on my 350x is started with a 12 to 1 and turned it in a lathe to lower the compression to about 11-1

i had a old 10.25-1 and this 12-1 so i just turned it 1/2 the difference in highth

[The Goat]

dirt...all the pistons interchange between years i believe. the difference in cc's is entirely with stroke.

I can get em pretty cheap if you're interested. wiseco...both 10.25 and 12:1

And... who told you that .002 will increase the compression to 11:1??

Not trying to bust your balls but where did that amount come from?? , I'd think more like .020 but again, thats just a mere guess. Not too mention that they only offer 10.25:1 or 12:1.

I called ARAIS today and they will make 2 - 11:1 pistons for 500$ I won't be buying those. While I had him on the phone, he seemed knowledgeable, I asked him about buying a 12:1 piston, chucking it in a lathe and removing material like Billy did. BUT, I already knew what his answer would be. Without actual engineering information, how much material to remove would be a mere guess.....

So, you might ask why 11:1? I don't want to be limited to race gas for a 12:1 that goes bad if it sits around, nor pay the price tag for it. There has been talk about 12:1 running just fine on 93 octane but that certainly isn't what I have read in the past. I was hoping with the correct timing that I could run 11:1 on 93 octane and that would match the cam I have close enough. I'm not WAX or Driscoll or Bubba Stewart and I just want to end up with a strong running reliable motor that I don't have to worry about pinging with......

Hey Goat, see what you can get the 10.25:1 kit if you could please and thanks for the offer.............

Same size bore, correct, but different pistons. The Wiesco part # is different between the 1st and 2nd gen 200x and a member tried using a 2nd gen in a 1st gen 200x and it didn't work (I think the pin is lower on the 2nd gen piston, or something like that).

Anyways, make sure it is for the correct year.

I'm looking at multiple wiseco listings now...including the one in my parts book, and it shows the same pistons for all 200 hondas...

Thats odd because there was definitely huge changes in each motor including bore and stroke. But of course I like the 86 mucho more and this ones gonna rip.............

[Bryan Raffa]

read the wiesco part number.. there diffrent!

[The Goat]

I'll have to hold off on that price dirt...I'm gonna call my distributor tomorrow and give em a piece of my mind. lol. actually just give em the info and help em out.

Not trying to second guess a piston manufacturer (OK, I guess I am ) But all you'd have to do is take a simple CC measurement of the combustion chamber with the valves closed and the piston at TDC. Determine the compression ratio then (Which should be very close to the advertised amount) and then play with the numbers of additional combustion chamber cc size until you get the amount your desiring. You'll have a more accurate idea too because of varying gasket thicknesses too. I can't remember the exact formula for calculating the compression ratio off the top of my head but if your interested I'll dig it out of one of my books and post it. Thats what I'd do if I were in your position.

Well, you obviously have no fear of taking a few thousandths off of a piston

Yes, please dig that out Billy. Then I can grab a 12:1 and go down to 11:1 from there, hopefully..... Guys the only goal is to get away with running 93 octane, maybe 12:1 can be built to run that but I don't want to chance it.....

[The Goat]

didn't like the 2001 400ex come stock at 11:1...maybe i'm an idiot.

idk, i was just thinking that they didn't ping however high their compression ratio was.

i turn down 12-1 pistons all the time....and they all have ran on pump gas when im done.

its no big deal....i just never bothered to check the new compression

i just know its between 10.25 and 12-1
