Cold start

[smokeshow81]

Alright well for me being the newb I am...
just curious about the initial fire up

When I first fire her up the choke is on and she takes a few secs. but makes her way up to 3000rpms.
Now how long should I let her warm up in this position?
What signs will she give me that shes ready to ride?
Or
When should I shut the choke off?

Start with as little choke as possible (always took full choke for my 93), once it catches you choke down to about 2k rpms for a few (read 2 or 3) minutes, start decreasing the choke as much as you can without killing the engine until you can use your throttle hand to keep the revs at 2k without the choke, do that for another minute, gear up, and git goin'

Much will depend on ambient temps at time of start. The times noted above seem excessive to me, but my ambient temps in SOCAL may be higher than yours. My routine from start to rollaway is under a minute and consists of the following on a stock 2000 Kat 600.

Full choke lever, start engine

When RPM's start to climb rapidly above 2000, decrease choke to maintain at 2000 (+/-)

After less than 30 seconds fully remove choke, check for good throttle response off idle, and go. Note that idle will not be at normal speed, but as long as you're not stumbling off idle, away you go.

If you are running the choke for several minutes, and you REALLY need to run it that long, I'd be looking into getting some carb or jetting work done, that ain't right, and shouldn't be necesary.

This is true. Mine also seemed to take a lot longer to warm up than most others (and those times I posted are about 25% shorter than what I actually had to do to mine)

Ran great though so hey

nice guys thanks...

When the ambient temps here are around the average spring temps in CA... (read, our summers) then I almost don't need choke... bupm start and turn it off.

When things start cooling off (avg temp under 50) then it takes alot longer...

What if it's hard to start cold & the choke seems to have no effect at all? I just have to keep hitting the starter until it keeps running. I've tried feathering the throttle as well as half-open & wide-open throttle starting, but that doesn't help either. Starts just fine when warm without any choke.

I replaced the plunger seals and now I don't have starting problems anymore.

'Scuze the noob .... plunger seals?

[Kfreak]

Seals that are a part of the choke system. A plunger is a brass piece that slides and opens and closes holes in your choke system. Got a manual???

[BrianT]

Just a service manual I downloaded last night. I did a search in the PDF for "choke", but it came back with nothing. Is that the manual you're referring to?

[Kfreak]

Any manual that has pic's. I have a Haynes manual. Carb's 101 may have some pictures of what I am talking about.
