Let's talk stalling...

How often does your bike stall?

  • My bike never stalls

  • My bike used to stall when first ridden, but doesn't now that I have more miles on it

  • My bike stalls when first ridden but is fine once its been running a few minutes

  • My bike stalls whenever the mood strikes

  • My bike stalls when cold unless I rev it up, until its warm

I know it starts better and idles better ,have nothing bad to say about the booster plug , no it doesn't make it a Ninja but it does smooth out all the edges .I really don't care about added performance , hate loud pipes anyway .The other best thing I have done was a 40 tooth rear sprocket .

Mine has never been a really bad staller, only occasionally it would happen on start up and that seems to have gone away . I don't think it's a cure all but I feel certain it has helped my bike .

After once again stalling like a wet fart, I was wondering why the throttle position sensor hasn't been brought into the conversation. I remember there was recall on a number of Yamaha TDM 900s because of faulty TPS causing stalling. Could it be the culprit?

Mine (currently 1400 miles) seems to have two stalling situations. The first, when it's just been started cold, is a classic stall--unless I give it a lot of throttle (say, keep it over 3000 rpm) it just shuts off a few seconds after starting. This goes away after maybe 30 seconds to a minute. The second situation, which can occur at any time (though it's most common when the bike's cold) happens upon leaving an intersection: I open the throttle and start to slip the clutch, and sometimes it dies at that point. Paying closer attention, I'm picking up a tiny bit of bog (that is, a brief drop in engine speed) when I first start to open the throttle. If that happens to coincide with the beginning of clutch engagement, I've got a stall. So far I'm dealing with this via careful technique, figuring I can train my muscle memory to blip the throttle up past the bogging point before beginning to release the clutch (this is, of course, a bit different from the way my Harley behaves, so training two independent muscle memories will take a bit of time). But I also think I need to turn the idle up a tiny bit, as the tach reads about 1000-1050 at warm idle. For cold starting, I'm about ready to buy a "cruise control" (throttle lock), just to hold the engine speed up during that first half minute or so... I can then use the time to put on gloves or do something else useful.

Well I've had an interesting morning. Shortly after setting off the bike stalled for the first time while changing down for a right turn. I thought, 'that's unsual'. Carried on for a couple of miles, then while descending a hill using engine braking, I noticed there was none. The engine was racing with the throttle closed. At the bottom of the hill, slowing for traffic lights, the engine was revving so hard I hit the kill button and pushed it to a lay-by. So I decided to cut my trip short and return home. I got back by starting it in first gear and putting the engine under load quickly, to stop it screaming. Throttle is opening and closing OK so I'm baffled. What was a liveable with stalling problem has now developed (faulty sensor or it's something else?). Any ideas?

I suspect that the throttle body assembly is out of whack or something like that. The bike would not rev up much if the throttle body was not opening to let enough air in. Good luck

Thought it likely a sensor, MAP maybe, was playing up. Can't remember seeing the MIL light come on. Will check that tomorrow. What I did notice is a slight seepage of oil on the fins, right side of the cylinder head. Hard to tell if I was down on power as I took it easy in 4th going back. It's a bloody worry as I don't have much cash to throw at it.

I would suspect the throttle cable isn’t returning fully ,can you hear a click when closing the throttle quickly ,bike not running, it should click a little as the butterfly closes completely?
If you can’t hear that then maybe the cable is hanging up on something .
For it to rev like that the butterfly has to be open more than it should be .
Or an air leak on engine side of the throttle body could produce the same effect .

I let the throttle snap back a few times until I got the click. Started the bike and got a normal idle. I'll have to run it a bit and check the cable out fully later to be sure, but I reckon you just about nailed it.

On my rental trip in Montana this summer, I had a few instances when the bike would idle around 2500-3000 rpm for a while. This pretty much always followed a sustained highway run at or near the speed limit (it's 65 and 70 on the two-lane roads in Montana), when I was wringing its little neck to keep up with traffic. It never ran away on me, and if it didn't settle down by itself after fifteen or twenty seconds I could make it go away by blipping the throttle a few times. Makes me wonder if the throttle butterfly is prone to sticking a bit.

I notice the Himalayan doesn't have a dual-cable setup (one cable to open the throttle, another to pull it closed). Noticed the same thing on my GS. My Harleys, my KLR, and pretty much every post-1980 motorcycle I've owned have had dual cables. Such a common feature I assumed it was required by federal regulations or something. How does Enfield get away with having just the one cable? Push-pull (rigid wire)?

Here are some decent photos of the Himalayan throttle body. I'm downloading any I find to build up a photo library for the bike. Maybe I'll sell them to Royal Enfield for a future edition of their service manual😉
Ok, there does indeed appear to be a throttle return spring. Good pics. Very good of you to dismantle your steed for the common good! What are we to expect next?
