What Carbs Fit My 90? Finaly Found One!

[Gearheadtom]

I searched around and cannot find what carbs fit my 1974 Honda Atc90. I've heard that some 110 carbs will fit, but what years? What carbs from other machines (quads, trikes, etc) will work my machine? I desperatly would like to find a carb for my 90 so I can get it running!
Any help at all would be greatly appreciated!


Edit: How about a Trx90 carb?

Someone out there must know what carbs will fit.

I know someone out there knows what carbs fit my machine. I found a carb for a 1985 Honda Atc110, and it says "90" in the title, but I want to make sure it will fit my machine before I buy it. Any help would be great!

Have you checked out beatrice cycles? they sell brand new carbs for these trikes pretty cheap. Jim

The cheapest carb they have is a little more than I want to pay, but I might get one from them if the one on Ebay daosen't fit.

I want to know if that '85 110 carb will fit '74 90 before it's gone off Ebay. I want to get my 90 running before it gets to cold around here!
Does anyone know if it will fit?

Another carb question. Will a CT90 carb fit my Atc90? If it does, I might be able to find one cheaper than an ATC90/110 carb.

I found this carb on Ebay, will it fit my '74 Atc 90? If it will fit, I want to buy it quick before the bidding ends

I done some searchine on here about this, and I've found that a CT90 carb will fit, but I'm not sure which years will fit. I desperatly want to get my 90 running. If anyone could answer my question, that would be great!

I know this has been covered in one form or another. The 110 carb will fit if you use a 110 intake but you will have to grind some on your head as the 110 intake transition to the 90 head is a little bigger, unless you don't care about how your trike runs. The ct90 carb will fit, but is bigger than the atc90 carb. It should work with the 110 intake manifold and once again, you need to match port the 90 head to the 110 intake or the resulting "step" will make your trike run crappy. The aftermarket large intake manifolds were based off of the ct90 intake design but with a larger inside diameter. The ct90 intake manifold will bolt up to the atc90 head, but the ct90 intake isn't turned out to the side of the engine and you will have interference problems with the tank. The outlet of the atc110 and the ct90 carb is larger than the outlet of the atc90 carb and the inlet side of the atc90 manifold. Either way you will either have to modify either the inlet side of the atc90 inlet manifold with the atc110 or ct90 carb or you will have to modify the inlet on the atc90 carb if you use the atc110 intake manifold. I hope I didn't make that too complicated or too hard to understand.

So can I use the Atc90 intake (which I already have) after some modifying with the CT90 carb?

[Gearheadtom]

Should I buy the CT90 carb? I realy want to get my 90 running.
I've also been looking at this carb. http://cgi.ebay.ca/1985-HONDA-ATC110...item518c353fe6 It's pretty rough, but it's the cheapest, complete one I can find on Ebay.

The ct90 should work but you may have to rejet. Also you will probably have to modify your atc90 intake some. Buy whatever you want to buy. You will have to live with it. I don't really know anything about those aftermarket replacement carbs. Whatever you get used, you should probably tear it apart and see what it looks like internally and you should put new guts in it just to be safe. The jetting with a different carb can be a crap shoot. Best of luck with whatever you choose.

I think I'll go with the CT90 carb after I get a shipping estimate, If I can before it's gone.

ct 90 jetting will should be pretty close if not use your atc 90 jets in it.
I have just put a 110 carb on a 90 and it needs a bigger main jet to get it running better but I used a atc 110 manifold too so it was an easy bolt up.
