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

Had an interesting talk with a dealer yesterday regarding stalling. He said that he'd spoke to Royal Enfield regarding stalling and they couldn't give him a definitve solution, but suggested that he try the Bosch with an NGK spark plug. The dealer then got on to NJK to find out the equivalent plug and got one couriered over to fit in my bike. When it arrived and compared, the dealer wouldn't fit it because he said it didn't match. Anyway, long story short he played around with the o2 values and sent me on my way. The bike didn't stall once on the way home, but I need a few more days riding to see if the problem is ironed out.
Just putting the information out in case it helps others. Nevertheless, once I find a replacement spark plug, I'll try that too.

Some people report better performance with the NGK iridium spark plug. When you say the dealer working with O2 values, can you clarify? I was under the impression that sans updates, the ECU maps are not modifiable. Thanks in advance

I can't be specific, he just said he'd run diagnostics and do some tweaks. On my TDM o2 values could be changed manually on the clock, which many did in an attempt to iron out low RPM fuelling problems. My understanding, though, is very limited in these matters. Better someone else clarify.

I installed a NGK iridium plug. It only stalled when first started. It ran fine after it idled for a couple of minutes. I think that's pretty typical. The plug was only $8 and sure didnt seem to hurt and may have helped the situation.

With the 500 EFI bikes, the factory Bosch plug commonly gave trouble. NGK seemed better, and some preferred iridium. Nearly all concurred that one heat range hotter was the best.
Don't know if the Himi will parallel this behavior, but it might.

Update on mine: used to never stall except if I didn't tickle her up after starting, now taken to stalling on arrival at roundabouts! Weather hotter now so eh? WTF? Mentioned it to Chocolate Chisel obligatory service mechanic when I left the bike for 7000km service and he did absolutely naff all to fix it, cheers mate...

Try the ngk iridium replacement massive benefits I the winter MO this over the standard plug no stalling. Will run from the start with no issues but still let the engine warm up for a few minutes first

I think this gearbox may be subject to fine tolerances with the clutch play.
When i bought mine the clutch had 3-4 mm of play ..
I had issues with gear changes, getting them clean, getting the smooth up changes i expected of this modern gearbox and getting smooth down changes as well ...
However ...
When i set the clutch cable play to => 2mm the gear changes noticeably smoothed out ....
Me or the bike ?..
I do not have a comparative data ... but my real world engineering experience says better ....
Your thoughts chaps ?

The owners manual calls for 2-3 so it would make sense if you adjusted it to 2mm and it feels better then close to 4mm
When mine get clunky I adjust it up to 2mm, never think to check to see what it is before hand.

Stalling returned, so I've ordered an NGK iridium plug. It can get embarrassing and frankly dangerous to stall at junctions and roundabouts. The other day I filtered to the front of a queue on a roundabout and stalled, holding up traffic. Much swearing ensued.

A month ago I thought the team was just wingeing about this stalling problem, as I had no problem except when cold, but now mine at nearly 8000 km on the clock is stalling when warmed-up, whenever it's really undesirable, like Wintrup at the roundabout, in the post above. Seems to be mostly governed by Murphy's Law. I read on adv forums that the tickover can be adjusted by a small recessed screw on the throttle body, accessible once you raise the tank. Haven't had a look at that yet. Pinched vent hose also mentioned by CarstenB. My Himmie groans a few times with some seconds between groans when I get home and turn off the ignition: is this the EVAP system groaning? (No smartass rejoinders pls :cool:)

My breather hose was literally disintegrating, so I found some tubing and replaced it. I also rerouted it at the same time to make it less liable to kink. My ticker over is low, so I'm going to have to adjust it. Hoping that and the new iridium plug will sort it. That all said, my TDM used to stall in a similar fashion when warm and never quite fixed it. I don't like too high a tickover, especially on an air cooled bike. So it's a shame (on RE) the adjuster isn't positioned for easier access.

My bike never stalled until recently. Granted I have less than 500 miles on it. Before the service, my tank would vent whenever it was opened. After the service, it does not do that anymore. It does stall now from time to time despite of warming it up a bit. I think that my idle when not so warm is too low in my case. It starts right up when it happens.

My iridium plug hasn't made any noticeable difference to the stalling issue, which generally occurs when the bike is well warmed up. I will say that my idle is set too low @1050-1100 rpm, which wasn't corrected by the dealer on my last service. This wouldn't be so bad if idle was easily adjustable, like on my last EFI bike, but unless I'm mistaken it isn't. The only way I cope with it is by anticipating it at junctions and roundabout and blipping the throttle to keep the revs up. As much as I love this bike, I'm now starting to accrue a number of things that niggle me. Maybe I'll start a thread on that soon.
