cam question

[84honda200s]

ok as you guys know i needed a cam so i got one for a 200x. can i put the 200s sprocket on the 200x cam?? i would also like to know what the best cam chain is. i herd DID was the best but i need more input.

the sooner i get this thing running is the sooner i can go riding.

[thefox]

Yes the 200s procket will fit the X cam.

[84honda200s]

thank you fox

can someone tell me if the 200x cam has the same lift and duration as the 200 cam? I have a 185 and a 200 and am wanting to make one of them pretty quick - probably the 185..

I was thinking: split the 185 case and check it all out.. reassemble and put a 200 cyl. and head on it with a .20 over 200x piston. Will that raise the compression some?
If the 200x cam has better lift I will get one of those and run it with a 200x carb, uni filter and a dg pipe

sound like a good plan or not?

[84honda200s]

yea go with the 200x cam. it has more lift than the 200s. put the 200 cyl with a 200x head . (unless you want decompression) then get a 12:1 piston for it.


it all depends on how much you wanna put into it and how much power you want.

[thefox]

The 200x cam has more lift, I think the same duration though. I would go with the 10.25:1 wiesco piston. The 12:1 is ok but you will need race gas, a good headgasket, and a very good pullstarter. I just don't think the 12:1 was worth it over the 10.25:1. (yes I have a 12:1 in a 200s and my friend has a 10.25:1 in his 200s). The 200x piston is 9:1 compression rated and cost about the same as the wiesco.

Yes, 200x cam, carb. dg pipe, and uni sounds good.

[rally4x4racer]

thanks fox - your a true voice of reason.

I dont want to get alot into it. I have access to a machine shop and can mill the 200 head or run the 185 head.. I dont want to go with the 200x head tho cuz I would have to buy one.

this is a trike i picked up in decent shape for a couple hundred bucks... I would like have it upgraded and still have less than 600 or so in it.

I have several 185-200 motors also - just no 200x :(

where did you get your info on the piston? I can get a honda piston for about half the price... or a proX ( but I dont kno if they are any good)
am I shopping in the wrong places?

Also, does it matter what year it says it is for? I am looking at a piston on ebay and it says it is for 86-88. It will be going into a 81 ATC 200 cyl (bored to match)
is this ok?

thanks - heres the auction info.

[84honda200s]

here is a great link. it helps me alot. http://www.3wheelerworld.com/spexhome.shtml

just look for the year. then look for the model. it gives most specs for most honda trikes.

[rally4x4racer]

yea I use it alot too but it doesnt list the cam lift and stuff like that..

It wont tell me if it matters to use a differ year piston when swapping from 200x to atc 200.

[84honda200s]

ooooo yea lol sorry man. i would think the pistons would swap as long as the bore is the same and the pistons have the cups in it.

[thefox]

Don't get the later model 200x piston (for 86-87 200x and TRX200sx) it will not work. The bore is the same but the piston will hit the head, someoneelse tried it, http://www.3wheelerworldforums.com/showthread.php?t=43319&highlight=200x+piston I would not use it just to be safe.

As for price, The honda piston is cheaper but the weisco kit has the piston, rings, clips, and piston pin. Honda makes you buy everything seperate. I have not used a ProX, and I don't know if they make the higher compression pistons, they may only make the stock 200 (non X) compression piston.

Another thing to note is you can use a 1980-1983 and 1986 - on XR200/XR200R piston. They XR piston is the same as the 200x piston but the stock size is the 2nd bore for the 200x (stock bore for the XR is 65.50 compaired to the stock bore of the 200x at 65.00).

Here is a good one... http://cgi.ebay.com/ebaymotors/Honda-XR200-XR-200-ATC-200-Wiseco-Piston-Kit-4156M06550_W0QQitemZ200065069194QQihZ010QQcategory Z35595QQrdZ1QQcmdZViewItem

Here is a post with somemore info on cam choices. http://www.3wheelerworldforums.com/showthread.php?t=35230&highlight=megacycles

Cams really depend on where you want your power and how much money you want to spend. Generally the "better" cam will have more top end power but sacrifice at least a little low end. The general progression of cams you are looking at goes something like.. stock 200/185, stock 200x, stock XR200R, stock XR200 (Discontinued, now part # replaced with the XR200R one), then aftermarket companies.

[rally4x4racer]

ok.. I am guessing that the XR200R cam is the hottest stcok cam I can put in it - unless i can find a xr200? heres a link to one I just found http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=330072205004&fromMakeTrack=true
and - you did not mention, but the xr200 piston is 10.25:1 right? thanks

[rally4x4racer]

hey, speaking of cams.. any idea if the 125 has better lift than the stock 110? I have like 3 or 4 old cams laying around and one of these days I am going to mic them suckers to see what I have.
I would like to put something better in this 110 - without paying 100$ for a new aftermarket - .........ideas??

i dont know that the 125m will swap..... just guessing

[84honda200s]

hey guys. i put the x cam in my trike now should i adjust the valves to 200s specs or to 200x specs? the x needs to be at 0.002 and the s is 0.003. is it normal for it to idle like a drag car? you know like it is going to stall out but it doenst.

[thefox]

The stock Honda XR200 piston is 10.0:1 compression.

That XR cam looks good; it is also from the older XR which is supposed to have a slightly better cam then the newer ones. Of course that is providing the cam is the original. Apparently Honda switched to a slightly milder cam in the later XR motor and replaced the old part # with the newer style cam, this was to help emissions, or at least that is what I have heard. I was thinking of trying the aftermarket cam that is on ebay, I asked the seller and they said it is a stock XR grind but they never said what company makes it. Nice price though, here is the link (they list a new set about every week)...

I am not sure if there is a difference in the 110 and 125 cams, I do have a performance atc110/125 cam I would sell cheap. I will pm you about it.


84honda200s -
The 200x is the .003 and the 200s is .002. I would set it at the 200x (.003) specs. if it were my trike. The cams are different but the rockers are the same.

[84honda200s]

thanks fox. a cam out of a 83 x shouldnt cause the valves to hit the piston shoud it?

thanks again

[thefox]

Nope.
How does it compair to the stock cam in the 200s? Much of a difference? I have a friend who has a 200s and at some point we may put the spair 200x cam that I have in it.

[rally4x4racer]

fox - that link is broken..
try to send it again if you can.

the 200x has better compression so it would be better to run it right? I dont see any listed on ebay for earlier years tho.. I will try to find an 82-83 wiseco for 2nd over on a 200x.

actually - the atc 200 wiseco has a 10.25: 1.. so that would work

the x cam has more lift on it. its a decent diff. it was worth putting in i think. i cant tell u the diff because my s one was totaly shot.

[rally4x4racer]

I take it you are talking abuot the auction? I saw the name KCwrenches - dont know who it is.. let me know if it is someone from here and I wont try to snipe it.
