The people are good to talk with they helped me on a yz125 problem I had.

Check Out Both Webcams And Megacycle Site, Both Say The Same As Mine.

I didn't see it on the webcams site, but those are the numbers on the megacycle site.
I'd believe it when I see it.
The one I degreed was nowhere near that. Did you actually degree one, or are you just relying on the megacycle numbers?

[HACKMUNCH TT Silver Member]

maybe you should call them and tell them they dont know what they are doing. what do you think there anwser to you would be?

[HACKMUNCH TT Silver Member]

yea, talked to JE yesterday, it is special made for EO but he said they should be able to sell ya just the piston. i recieved my 190 kit yesterday, they are doing just like i said. 74mmx100mm sleeve.

Looks like we are getting closer! Zomby really helped me out with my cam choice, with out him I would have never went with the 393-00. Megacycle even told me they would not do it for me but I insisted! Megacyclecams.com catalog says that the 230 cam is Int. .324" 235 Deg. Exh. .390" 237 Deg. But it also says the 330-x2 is .252" Exh. when it is really .352". So you decide. The 393-00 does not even really seem worth doing if the stock #'s are correct for the 230. In any case the 393-00 works with stock springs and makes a HUGE difference over Hotcams. Thanks Zomby.

Dirtbikedm220 - Can you just recap what is on your motor?  ie: bore, carb, exhaust.  I want to get a cam, but I dont want to change the piston or bore at this time - so i am looking for the best choice with the stock piston/bore.

[dirtbikedm220 TT Member]

143 big bore, ported head, BBR carb, K&N, Pro Circuit exhaust, Megacycles 393-00 cam, many 1" holes in air box. I ice race this bike, so my setup is most likely not ideal for you. I would say cam choice depends on how you plan to use the bike. I think to get the most out of the 393-00 cam you need the big bore and the higher compression. Remember, I'm just a fat drunk guy on a mini bike!

So are you buying the 190 kit from EO or piecing it together from JE?  Is the sleeve coming from JE too?

[HACKMUNCH TT Silver Member]

i bought EO 190cc kit, but if i build a few of these for customers i will be doing it myself since i can build it for about 1/2 as much. anyone want to buy a 330x2 megacycle cam brand new?

[ian30 TT Newbie]

Does the 330x2 work with a stock piston?  I was planning on going to a pe24 carb and was looking for a good cam to put in also.  I will eventually go big bore later, but I need it to "run right" with the stock piston/bore.  Do you have any experience with this?   Would I be better off with something milder like a "hotcam"?  Any advice is appreciated.

Its only on the one site, and since his site has other mistakes on it, I'm sure he would welcome, and appreciate the assistance from another professional in the business, as would I.
I see mistakes like that on lots of sites where custom guys try to cover too many manufacturers.
You can say what you want, I really don't care.
I'm in the camshaft business.
You aren't.
You took the numbers off somebodies site. I actually degreed one of those cams, in a head.
Lets see one of those magic $20 AT230 cams with those numbers.

well what are your "majical"#s then?

I'd be careful with the stock piston.  I've posted a pic previously showing that the stock piston has a much larger dome and valve clearance of the piston may be a problem cos the 330x2 is much higher lift than stock.  I'm guessing that is why EO had JE produce a piston with a smaller dome.

Hey Hackmunch go easy on Zoomby - You're talking to a guy who REALLY does know his cams.  

By the way why are you getting rid of your 330x2 cam ... I thought this was the best you could get for the 190 kit?  Have I missed something?

Also just a thought if you are putting together 'replica' 190 kits, don't forget that the top and bottom cylinder gaskets are specific to the 190 kit.

Where do you plan to get your 190 sleeve from?

[dirtbikedm220 TT Member]

I think he is getting rid of the 330x2 to get the 393-00. Just a hunch.

[smrmx14 TT Bronze Member]

do you guys see any problem using the 393-00 cam with wiseco 143 piston and larger valves from procycle?what about valve springs.Does anybody know if the alt185/lt185 piston pin size it might work for your 190 kit. Not sure might be same size as the dr 200 piston larger pin..

So you think it's OK to just copy someone elses work?
They spend the time designing a part in a real shop which they pay rent, taxes and insurance.
The guys at EO, BBR, ProCurcuit etc... are just trying to make a living and maybe send thier kids to college.
Get your engineering degree out and all your wealth of knowledge and design something on your own, who knows maybe you could do a better job and contribute to the industry instead of leaching off it.

[HACKMUNCH TT Silver Member]

wow it takes rocket science to resleeve a cylinder, and i need an engineering degree to run a boreing bar and a lathe? i will have to call LA SLeeve and tell them they owe EO $ for stealing there idea, god knowing that dont even do the work themselves. so EO are the 1st guys ever to make big bore kits, hmm thats new news to me. Well i will tell you this there customer service sucks, they dont want to anwser anyones questions, they dont want to sell replacement parts, thats BS. ask other guys on here, they have delt with the same shi$. I have my own buisness building engines, selling parts and so on, competetion never hurt anyone.

[HACKMUNCH TT Silver Member]

as for the "majical" #s i am just curious what he came up with.

[HACKMUNCH TT Silver Member]

also i think i have come up with an easy anwser to the ignition problems on these bikes, i am gonna try to adapt a kitaco 5 wire ignition to the stock 6 wire setup. i will keep you guys posted how it goes and yes i will give the public all the info for free, because thats how it should be.
