Kick-Starting the SR400/500: Starting the Engine with the Decompression Lever
An SR without an electric starter is started by kicking. We go step by step through the kick-start procedure, from finding top dead center on the compression stroke and using the decompression lever to kicking in a way that transfers your force well.

Starting an SR's engine means kicking it. Once you get the knack, it isn't difficult, but if you just stomp on the pedal without knowing the procedure, it won't start easily.
Here we show the correct kick-start procedure unique to the SR: find compression top dead center and get past it with the decompression lever.
01 Before starting
When the engine is cold, such as first thing in the morning, pull the carburetor's choke lever. When the engine is warm, don't use the choke.
Once you're ready, fold out the kick pedal. With the stock rearset footpegs, fold the footpeg up.
02 Find compression TDC and get past it with the decompression lever
- Straddle the bike and push the kick pedal down firmly. The trick is to push with the arch of your foot.
-
After pushing it down once or twice, there should be a point where it catches with a solid clunk. Sometimes it catches right from the start. This point is just before compression top dead center.
-
Squeeze the decompression lever under the clutch lever.
-
The resistance you felt a moment ago disappears.
-
Keep going and smoothly push the kick pedal down about 60 degrees. You're now past compression top dead center.
03 Starting with the kick
- That's all the decompression lever is needed for. Release it.
-
Return the kick pedal all the way to the top and take up the slack.
-
Kick it down in one go.
That's one complete cycle. If the engine doesn't start after kicking, start again from the beginning.
For the final kick, don't think of kicking the pedal away; think of crushing an empty can on the ground. Dropping your hips slightly and then straightening your leg transfers your force well.
