My '95 Ninja EX500 is very cold blooded and it takes a long time to warm up. I was wondering if anyone else here has the same trouble? Is there anything that I can do to cure this problem? Thanks, Joe

there was topic about this, the remedy was a piece of cardboard over a portion of the radiator.

^ Absolutely, but I have to use this only in sub 10*C temperature.

The needle on my ride hardly moves though. But when the bike idle smooth, it's the right temp to go ride

Does the bike not warm up as in the gauge doesn't come up, or as in the bike runs like crap? There's a difference in being cold blooded and just not getting hot enough to move the gauge.

It just idles & runs rough for about 10-15 minutes and then it runs great after that. The temp qauge seems to work fine. It just takes quite a while to warm up when started cold. Joe

Just wanted to get that clarification out of the way, it's easy to get people who put a little too much faith in the gauge - didn't mean to imply you were an idiot or anything (or that anyone else is ).

10-15 minutes is excessively long. Does it do the same thing whether you use use the choke or not?

 

[Ninja-Joe]

Well the choke helps to keep it running until it warms up. It's not really a big deal, it just takes a while to warm up and I was curious to see if anyone else has this issue with their bike.

my 1st bike (1997 Ninja 500) took at least 10 minutes to warm up on idle.

Or 2 mins of riding.

I never checked how long it takes on my EX500 really, I just let it idle on choke maybe a minutes, close the choke and take off. <= The gauge is still on cold, but it runs fine after a block or 2

Depends on the temperature - if it's below 10C, it takes around 10 minutes and half the rad blocked. If it's above 20, it takes a minute to be fine.

When it's below 0, I have to block off the entire rad and ride it for 30 minutes before it's fine! Of course, after 30 minutes, I'm usually not fine myself

Isn't there ice under 0 ? How do you manage to ride on ice ?

Not necessarily! I rode well into December last year, and the temperatures were negative 5 and 6 sometimes (not including the wind chill factor.) And this spring, I hit a few negatives as well.

I stuck to the main highways and was fine. The only reason my EX didn't see January was because my chain was shot and I had no cash to fix it! If I could find hte cash, I'd be buying some knobby tires this winter and running her year round!

^ I'm not there yet

Water in it's liquid form doesn't keep me off my bike though

 

[Jsvob03]

imaybe your coolant mixture has too much coolant (too much coolant to water, and it will take a little long to heat up.) or maybe your thermostat is sticking open a bit?

beyond that, i don't know enough about the bike to try to help.

My mechanic friend figured it out. My choke was sticking due to rusty needle valves. It idles perfect now.
