Non-responsive throttle in first minutes of riding

[auzzie599]

Hello,
So when I start my '08 GS500F, the first couple minutes of riding it feels like my throttle is very unresponsive, or that the bike is being starved of fuel.  This lasts for a minute or two, then things seem to smooth out after that.  This is much worse in the cold.  The bike has about 2500 miles on it.  Is this normal?

I'm probably wrong but it sounds like the bike is not fully warmed up before you set off.

how hot is it there?

give it a minute or two of full choke, then lower it and the throttle should be fine

it's not like other bikes where you can just turn it on and start riding

A lot of bikes "SHOULD"  Be warmed up.. but most people don't. I still warm up my dads 99 camaro before I drive it. Idk I think its a good habbit.

What's your start routine?

My routine is...

- Put on full choke
- start bike, let it rev to whatever it wants to go to. If that's above 3000rpm then so be it
- put bag on bike, put on jacket
- reduce choke until bike is revving around 2,000 rpm
- put helmet on, put gloves on, at a leisurely pace
- sedately ride off and take it easy for the first couple of clicks
- turn off choke

I follow the same routine on my fuel injected Honda 919 - of course I don't set a choke, but as for start, jacket and bag, helmet, gloves, sedately ride off for couple of clicks, it's the same.

The Owner Manual has this...

When The Engine Is Cold
1. Turn the choke lever all the way towards you. Close the throttle completely
2. Push the electric start button
3. Immediately after the engine starts, keep the engine speed at 2000 - 3000 rpm by varying the choke lever position
4. Move the choke lever to the "OFF" position approximately 30 seconds after engine starts. It may be necessary to use the choke longer than 30 seconds in extremely cold weather

When The Engine Is Warm
Use of the choke lever should not be necessary. Open the throttle 1/8 to 1/4 turn and push the electric starter button.
