what carb to get for 200x

[vince22944]

thinking about ordering this carb what you think?http://www.ebay.com/itm/Honda-ATC200...87e717&vxp=mtr. and what kinda of spark plug should i get for 83 200x?

That carb is good and you'll want a NGK plug. either DR8ES-L or a DR8IEX. the IEX is more expensive but a better plug overall.

PS, this could have been asked in your other thread.

[vince22944]

okay thanks man and do i have to adjust anything when i get it or is it good to go right out the box

[rg97]

I am not a tuning expert, so DOHC or barnett should explain based on your temperature and altitude. I think you said earlier that you were at 65 degrees @ 305ft elevation? If you dont hear from them within a few days here maybe send them a PM.

[vince22944]

Do they have the Ngk dr8iex plug at orielys or autozone or is it a special type of plug
And do I just screw it on or is they a certain torq

Hi vince;

We need more info.

What are the numbers on the side of your current carb or what size is it?

What type of riding are you doing mostly ie., slow or wide open throttle?

EXACTLY what mods does your bike have ie., high perf ex pipe, cam, piston, head porting?


CARB SIZES – To estimate the actual size of an oval bore carb it there is no size markings on it, you can measure the bore diameter on the outlet side then divide by 1.15


EBAY CARB SIZE – It is around a 21 mm.


JETTING - The stock Honda jets are 110 main, 40 pilot. Mikuni uses a different numbering system. See chart in link below. If the bike is stock and you buy a Mikuni carb that is close to the orig size, I would start with a 100 main and 37.5 pilot. If it has around a 97.5 - 105 main and/or 35 – 40 pilot, I would try those first.

SPARK PLUG TORQUE – If plug has not been installed, tighten it finger tight then 3/8 [almost 1/2] of a turn more. Once it has been installed, only tighten it 1/8 turn whenever reinstalling it.


PLUG LUBE – Install a little grease on it prior to installation. This will help preserve your threads in the head.


PLUG PURCHASE LOCATIONS - I for one do not know if they sell it at auto stores, call for info. They might be able to order it. Any motorcycle shop should have it.


PLUG GAP - .024” - .028”. Be VERY careful gapping the fine wire electrode plugs because the electrode breaks VERY easily.

I just ordered a MIKUNI Carburetor Carb CA06 the part where the intake goes is 24.09 and the other number is 49.16
I posted the link of the carb on here it was my first post on this thread I like to do a bit of slow and open throttle riding

[barnett468]

yes i told you that carb is smaller than an original one. it will not have as many peak rpm's or top end power with that carb, however it will run well up untill around 2/3 throttle. it will still run smoothly above that point but will just not have the top end power the orig size carb would.

[barnett468]

i'll see if i can look up the ca06 number to see what it is. back in around 20 minutes.

[vince22944]

How should I tune this carb when I get it it's raining here around 60 degrees 305 ft elevation

[vince22944]

Okay thanks Barnett

[barnett468]

Ok the CA06 is a 22 mm carb p/n pz26.

You want this carb, it is 24mm. forget about the ad saying 26, they are idiots.

We need answers to the questions in post 9 to mare accurately guess.

So Barnett,,, when are you going to explain to Vince that they are measuring and displaying the carb outlet side flange diameter, not the venturi measurements.....

Always research your part numbers before you buy.

A 22mm carb will decrease your performance, and will be difficult to tune because you will be looking for performance that just isn't there... Sell it and get the right size carb.

So this isn't good enough for ya?

This applies to the carb in your link.

Hey Vince;

Always research your part numbers before you buy.

The PZ numbers most if not all sellers on Ebay are using are the estimated bore at the end of the outlet whether it is a flange mount or spigot mount. Some places list the "PZ26" as having a 26 mm outlet and the place in his link says it is a 24 mm outlet. It is a 24 mm so either the other places calling it a 26 mm outlet are wrong or his seller is inaccurately calling it a PZ26 and should likely be calling it a PZ24.


The end result of this is many people buying what they think is a 26 mm oval bore carb for example are really getting a 22.

As far as I'm concerned, these sellers got to close to the carb when they mesasured it and got it stuck up their outlet!
