;DHi guys just a question for everyone , if I start my SR from cold using the choke and let it run for a few moments say up to one minute and then shut off the choke , without using the throttle at all should the bike settle down to a nice even idle speed ?? as on my bike as I take off the choke I have to give a few revs using the throttle and then take hand off throttle !!! what does everybody think??? Thanks TC

I turn my choke of almost straight away, but slowly (otherwise it will stall) - taking about six seconds. This is in winter, mind you it's an Australian winter. She idles nice and easy at that point.

I've seen in previous threads on how to start an SR, that nobody has the same technique for starting. For me it's no choke and no gas. First kick when it's cold, third kick when it's hot.

For me it's full choke hot or cold. Starting either way is one kick 95% of the time, two kicks 4%, and several kicks 1% of the time, usually the worst time. Most failures to start on the first kick are forgetting to turn the key on!
When cold, I leave the choke on until the bike will accept throttle. If you blip it carefully, this can be in less than a minute. Too much too soon will kill the engine. Once I can rev the bike I can get it rolling, I leave the choke on until I am ready for second gear, pull it up and shift
The carb on an SR does not have a true "choke", it's an enrichment circuit which enriches the mixture as opposed to reducing the airflow. It also has an accelerator pump, which is why any throttle on starting will flood the bike, making starting it a many kick ordeal.
When used hot, be prepared to reduce the choke quickly as the bike revs well above normal idle as soon as it fires. This due to the extra gas from enrichment circuit. I slowly and evenly bring the "choke" lever up and the bike drops into it's normal idle (~1000 RPM) and is ready to ride. Because it is hot already it will accept throttle without hesitation.
The hot start button on the carb simply pushes the throttle cable up slightly, advancing it without activating the accelerator pump, I've found this pretty useless unless you just want it to idle faster.

Whoa, sorry guys, I forgot I have a bigger Mikuni than stock. I was reading digiroc's post thinking, geez mine is sooooo different. Then I realized that it really is different.
BTW, I never use the decompression lever...ever.

Hi, Personally, I'd be a little reluctant to not use the de-comp with a high comp piston. I'd be concerned that I might break the kickstart idler gear with placing excess force on it... SR  |

hi guys, as im new to this forum - i dont know if this has been posted already, but if you search for 'kickstart sr500' on youtube, theres a few videos of people starting up their sr's

Hi, Personally, I'd be a little reluctant to not use the de-comp with a high comp piston. I'd be concerned that I might break the kickstart idler gear with placing excess force on it... SR I use the decomp lever to position the piston just after TDC ,then release it and kick. This way I get good rotational speed and flywheel inertia to bring the piston over compression on the starting stroke. I also might kick it over with the decomp pulled to clear the motor if I have flooded it. Do people use the decomp lever in some other way? Is there a Down Under technique? |

I'm in the same boat, I have a modified VM
bigger piston, open exhaust & cone air filter.
Its easy to start but very hard to remember
all the right settings. Since my starter(choke)
lever is useless I just start it with no air and
lower idle. then slowly open up the air to
2 turns open. then slowly turn the idle to
2 3/4 open. At those settings i have the best
throttle response in all gears so far. I think
I can do better, but don't have the time to
really fiddle with it. So right now I'm trying to
get in a habit of setting the screws back
after I shut it off so its ready to start up
again when I come back to the bike. Otherwise
I have to squat on the left side of the bike
and feel the slide hit the idle screw and
turn it to the right spot.
Anyways its different on every bike. Even if
you have stock everything. Each bike seems
to demand something different of its owner.
But yeah use the decomp.
less stress on internals.
Easier on your leg too.

No, past TDC, release and kick right through... SR |

hey there fe2cruz, you win the prize for most complicated starting procedure. Do you really get the screw driver out and adjust settings to start it?
That seems waaaay too hard to me.
Some advice I found when I was researching royal enfields - before I saw the light and bought a yammie.
If you can start the bike cold without choke, its probably running a bit rich and using more fuel than it has to.
If your carb is right, cold starting with choke, hot starting without choke, but maybe the hotstart button if you only just stopped the engine moments ago, is the go.
I use the decomp lever to ease just over TDC.
Don't use the little sight glass though. I even forgot to mask it when I painted my XT engine, but I do not miss being able to see the indicator at all.
