Hi all,
My bike is very new, fully serviced, all fluids up to level, everything's mechanically sound, but every now and then I have trouble starting the bike. I sometimes have trouble starting it when the engine doesn't fire on the first time I try to start it, and end up having to roll start it (which requires coordination not found at 7am without a coffee). I get the feeling I'm just doing something wrong because it shouldn't be this hard to start, and that I am possibly flooding the engine.
FYI I am riding a 2006 ZZR250 - Carburetted. The bike is past the wear in period.
The technique I use for starting the bike is:
1. Pull throttle back about 1/4 to a little past 1/4 turn.
2. Open choke all the way.
3. Slowly ease throttle back to idle position. By slowly I mean take about 3-5 seconds to bring it back to position.
4. Press the starter button, give it a 1/8th-1/16th turn on the throttle (tiniest bit of throttle) at the same time as it is trying to fire. Most times when it fails to start I've pulled the throttle back a fair bit, but not more than a 1/4 twist.
5. Ease off the throttle as soon as it's started, slowly close the choke as the revs climb up - I generally try to keep the revs below 3000 rpm, as close to 1500 rpm as possible (idle set to around 1100 rpm).
When I start the bike and I know it's warm, most times i don't bother with the choke... a little bit of throttle does the trick.
Most times this works. By most I mean 1 in 20 to 1 in 30 will fail and I have to do the roll start thing, which requires a lot of coordination and a strip of road about 30-50m long. I don't like doing the roll start thing and I think that I can avoid this by just starting the bike first time every time.
Am I doing something wrong? Is this something that just happens in carburetted bikes? Is this a flaw in the ZZR design?
