200x head on a 200s PICS

[jenndnn3]

They arent.

The 185 was different. But rumor has it they are discontinued. (been out of 200x mode for ages so someone will have to verify) As was the xr200r. But its changes yielded little.. The change for performance is really in this combination.
XR200r piston and cylinder with the topend matching to whichever trike you have (decompression) with the 185 cam.

I always heard they were different. Need someone with both to take measurements to see if there is any difference

[MonroeMike]

I thought they were different too. I see the cam listed for the 185 is the same also. Apparently, Service Honda only offers one replacement for all now.

Heads are the same on a 200x /185/200s/m/e Exc but the X model dosent have a decompression lever because the others are pull start motors . The cams on the X and xr models have a bit more lift . the 200x factory piston is a flat top design and the 185/200 models have a convex low compression piston .

[oscarmayer]

yea theya re exactly the same. the only difference in the cams and on the 200x the whole for the decompression lever was never drilled by the factory. (recommended for a 200s unless you like hurting your arm)

I pull start my without compression release with no problems.

I pull start my without compression release with no problems.

Do you Still have the factory compression piston ? A factory 200X or high compression piston can be a painful experience until you get the feel for it

Today, Honda only list one part number for every 185/200/200x camshaft because they discontinued all the others. There was a thread about it somewhere on the forum.

If you go to the above they list two different cams for the 200s. I didn't check other models cam numbers though

Also if I get a used 200x cam and put it on my 200s will there be any performance advantage if the cams are different?
The 200s has new exhaust and a better flowing air filter.




One last thing. The description of the cam I am eye'ing read this- Camshaft has wear...There is a spot of very light pitting that I can barely feel with my fingernail on the top of one of the lobes...Remaining lobe has a spot of light pitting on the edge of the lobe...Gear Teeth and threads are ALL whole, and in good shape

Do you think this means it is unusable or should it be okay?

[leevarnado]

the reason its two diff cams is because one is the original and the other is the one thats replaced it.the original cams are no longer available,now there is just the one cam that has the same part numbers as the rest.i wouldnt use any cam that has any type of wear,that wouldnt be very smart.but thats just my opion.

[litebulblsc]

Well my engine is still together and I don't know if my cam is even in any better condition.

[MonroeMike]

I agree with leevarnado, I wouldn't use it.

Post for one in the classfieds here, maybe someone has one.

[litebulblsc]

it was listed on ebay for 99 cents. that was the main reason I was interested.

[leevarnado]

is this the cam your watching,if so that cam isnt any good.its worn badly,an 185 cam would prob have more lift than that one.
