Carburetor noob: can I just..

[epidemiks]

Can I just bolt on any old (new) carb, assuming it's the correct size for the intake port?

Planning to swap out my push/pull throttle assembly and bolting on a new carb (mikuni or something else).
Will it be as simple as fitting the carb, plug in the fuel line and throttle and go?

Want to ditch my stock, overly complicated thing for something simple and effective, and easy to repair/maintain. Performance isn't #1 priority, but the stock one does seem to strangle the life out of the engine, and keeps jamming up.

Cheers!

there are certain carb's that will be easiest to jet for your engine.

im going to guess its whatever Mik that's proper for a CB200

Swapping carbs is nothing new to the motorcycle world. It's not going to be as simple as just finding ones that fit and go. You're more than likely going to have to do some tuning, re-jetting... Plug and play is not a very common thing in the carb world even swapping stock for stock, you'll always have to fiddle a little bit.

tuning and jetting no problem, happy to learn as part of the process of learning more about bikes in general. Just a bit frustrated by the stock carb getting me to get stuck in the middle of traffic last night in the rain, pouring fuel out the airbox onto the exhaust!
I'm used to being able to just roll up to a guy on any street corner in Phnom Penh and paying $2 for a carb clean while I lie on his hammock with a coconut. A bit different here in Melbourne

I guess I'm also curious whether I need to be conscious of down the line issues after a change.. flow on effects if you will.

It's a 97 CB250, disc version. How do I tell what fits? just pull out the carb, measure the intake port with a micrometer and check out the Mikuni catalogue?
Cheers

This sounds dirty.... That is all.

There's nothing wrong with the carb you have, if its leaking, make it stop.
The solution here is to learn how to clean your carb, not replacing it with something that's going to require a lot more work for little to no gain.
Overflow is simply either float height set incorrectly, or if its sudden, probably just a stock float.
Pull it out, take it apart, clean it well, set the float, and youre golden.

haha! on second reading, yes... Don't knock it till you've tried it though!

Yeah, true. I'm being a sook. Appreciate the straight talk. Took it off and apart last night, and tonight will be examining every inch of the thing. The fuel comes out through a hole in the upper left on the airbox side that leads up to the vacuum chamber.

Photo isn't my carb, but hole is in the same location.

So I found the culprit. A thick dam of black sludge had formed deep inside the drain point.

Previous owner had not ridden it in 10 months so must have formed then. Didn't spot it the first time as it looked like it was meant to be there. Took all of 5 minutes to clean out and rebolt onto the bike. Bike doesn't hesitate now in 5th gear and no more fuel pouring onto the exhaust.

Thanks SONIC for the kick up the arse.
