Hard cold start

I have a 83 Honda Shadow that runs great once it gets warmed up but is very difficult to start and will not idle when it's cold. I was thinking about rebuilding the carbs this spring in hopes of it starting a little better and run a little better when it's cold. Does anyone have any ideas of what the problem may be? A couple of my friends keep saying it's the nature of the beast because it's water cooled. I say my car is water cooled and it starts and runs fine when it's cold. By cold I mean that it sat overnight and the following day it is very difficult to start.

Re: Hard cold start

Does it have a choke? and are you using it?
Once the engine starts, I have found that you need to ease back on the choke for a block or so, then release it completely. But that was on my cb900F.


On an FI bike like my 929, I let it warm up for the time it takes to click it into first, then I'm off! I used to wait at least 30 seconds, but Dan Kyle told me there's not reason to do that.

Really. I always let my FI bike warm up to 100 degrees (F). I was told that if you get on it while its cold you have a better chance of fouling the plugs.

Re: Hard cold start

I was told that by the salesman also. But I'll listen to an expert engine builder over a snake every time. And I have never fouled a plug in the 929.

Re: Hard cold start

Thanks for the replys so far. Yes I do use the choke and I turn up the idle speed to about 1500 RPM, but maybe I should turn it up higher when it's cold. Any suggestions on how high the cold idle should be?
I've owned Hondas in the past and I've never had a cold idle problem like this.
