Two-stroke warm up problem?

[DW86]

How do you guys warm up your bike. Is that necessary especially in winter? how do you guys use choke?
I am a new rider and got a rgv 250. My bike dies sometimes when I start the bike and try to give some gas. I leave the choke on still at that stage so is that may be a problem to cause it?

Pull the choke back, start your bike give it 20-30 seconds with the choke on. And then let it idle for 2-5 mins without the choke. Works for my rg on cold mornings.

The rg really liked to be warmed up even if I let it sit for an hour.

Mine's not a 2-stroke but i was having the same thing happen with my 250. Lumpiness and cutting out.

It seems now, there was no problem at all but my use of the choke.
I was trying to get the choke completely off before riding away which was unnecessary.

Just close the choke fully (on) for start up and let the bike warm for a minute or two while you get your gear on.

By the time you're geared up, or maybe before, it'll start to rev up quite high so lower it down a little by opening the choke slightly (moving it towards the off position).

Dunno what your bike idles at. Mine, when warm, idles at 1500. When i'm ready to roll, i open the choke until it's revving at around 1750 or whereever it'll sit without getting "lumpy".

Then just leave it on while you ride for a while. The exact length you should leave it on for will vary with the way you are riding and how cold it is. It's a bit of a trial and improvement thing.

Apparently you should ride with care when the choke is still on as the revs can jump up suddenly.

You'll probably find that now and again you'll forget entirely that the choke is still partially closed until you pull up at a junction and its revving higher than normal.

Anyway, hopefully one of the more experienced guys will be able to confirm that the same method will be ok for your bike. ?

I use the choke to start my RGV, then just blip the throttle for a short period of time, till it gets enough heat in it to idle (maybe 20-30 seconds?)

You seem to have a few question about your RGV, give me a PM if you'd like to go over the bike together in person one day, might be able to sort a few things out and answer a few questions

I do nearly exactly what Ripperjohn does. Works real good. As he suggests, its quite obvious around town if you have left it on. Check the choke is fully off before or as you hit the open road.

Thanx bro. That is really helpful. I found my bike have sort of some problem as yours did.

My rgv sometimes could be real hard to start again. I don't know what cause that but it seems I do need to do a good warm up to it before I ride.

The main thing is to be real gentle with it until it gets some temp into it. So many people start bikes & rev them real high, maybe they just like the noise. Don't put it under load or rev too high until warm. I don't tend to leave them idling forever & a day.

Sure do, down here in chch it can be 3c according to the thermometer on the bike in the garage it'll start 2nd kick every time last 2 or 3 mins with choke and it'll start to die unless you stick it back in.

Start to ride once its about 15c-20c, but it runs like a dog until 30c and I refuse to give it more gas than it'll accept so I just crawl the first km or two. :P

I don't get into the power (7k+) until its indicating 40c on the external engine barrel temp probe. During the coldest winter mornings that can take forever/never though, stupid Malaysian temperature design Could block 1/4 of the radiator but its no biggie.

Seems to work for me.

Talking about warming up...

There's a guy at Pak'n Save where I work that has a 125 2 stroke (not sure what make or model, sorry guys). Okay now last night he walks past with his helmet in hand and goes out the dor to his bike. A minuite later, he's revving the SHIT out of it. Now, it takes about 30 seconds to get to where he was parked, ten seconds to put the helmet on (only protection he wears on a wet, slippery day), and maybe another ten seconds to start the thing because it's in such bad condition...

AND FUCK! He revvs the crap out of it. This was last night at 10pm, farking freezing weather, wicked cold engine!

I'll find out the make and model, he'll be selling it soon, he'll break it and say there's nothing wrong with it. Steer clear.

I'm still jealous that he has a bike and I don't...
