This is my first Cruiser, and I'm noticing hesitation in getting the ignition to fire (1-2 seconds). After firing, I've had the engine stall out in neutral while I was getting my gloves to get it warmed up. I know the older bikes, you had to open a fuel line, and coax them to life, and I've seen a lot of other people w/ Harleys who'll rev up the bike for 5-10 minutes (not popular w/ the neighbors). When riding, I have noticed no issues. Am I supposed to rev up the bike to a certain RPM while it's in neutral to keep it from stalling?

Oil level looks okay.
I filled it w/ 93 octane gas based on dealer's rec. even though manual says 87 should be fine.

I have about 120 miles on the bike and will be taking it to the dealer to take a look.

I found a previous topic

stalling at low speed

hi all, have had an intermittent "failure" in which the mc (2017 bobber) stalls when clutch is in, bike put into first and about to release clutch. im not a novice (riding since 1986) and this isnt a newbie stall...it feels like the rpms suddenly drop. this has happened 4x in about 4k...

it's sort of similar, but this is happening off the bat. Supposedly there was some update that fixed this? I had something similar w/ my kawasaki z900 hesitating to fire (though it never stalled) and they adjusted an idler screw which fixed it? But dealer says no easy fix like this

Anyone have any reassuring stories...

Have you checked the air filter and spark plug gap?

. You're not doing the bike any favor by using high octane fuel. I gather this is a new bike. The onus is on the dealer to fix the issue!!!!

Thanks for the tips. I haven't checked these myself, but I'll make sure the dealer checks those things.
I only have 125 miles on the bike so I can't imagine the airfilter going bad in that time

It happened once on Sunday and I thought maybe I flubbed something, but three times on Tuesday which seems like something progressing to worse.
I guess if it stalls worse I can have it towed since Triumph gave me the 2 year roadside rescue.

Thanks. I was just hoping someone would say they had this happen and they figured out a ritual to rev the bike to fix it.

9 times out of 10 issues like this turn out to be bad battery connections. From the factory there is paint on the earth strap connections. The first thing I did with mine was to take the battery out and clean all the earth connections. The battery end has a plate which can sometimes have paint on the underside. At the frame end the strap isn't actually bolted directly to the frame. It goes to a bracket which is then bolted to the frame. Take the bracket off as well and clean the connection between that and the frame.

Is this happening on cold start or warm? Whats your idle at on cold and warm start?

Sometimes a bad tank of gas will get ya. Happened to me once. Got gas at a random station and my bike ran like ****. Siphoned out and filled again and all was well

FIRST THING: start running 87 octane like Triumph recommends! Higher octane fuel has additiv that make it slightly less volatile therefore possibly causing a misfire or two especially on cold starts when you need a richer mixture. I would say a couple tankfuls of 87 should remedy that issue. If not….then check the battery ground connections as mentioned above.

This only happens on cold starts. I need to confirm but I believe it starts off around 1400RPM and after a few minutes comes down to 1200.

I'll return to 87... but I'm suspecting it may the battery connections b/c it also seems like the bike is hesitating to fire. Or it could be both. Thanks for the suggestions guys.

I doubt it's the octane as standard fuel in the UK is 95. I generally run mine on premium which is 97, not for the extra octane rating but simply because premium has better detergents and less ethanol.

As I have two bikes there are times when the Bobber has several weeks without running and the premium fuel lasts better in the tank.

It runs equally well on both 95 and 97 petrol.

You speak RON oh Kemosabe:

RON is the octane measure used globally and it's more efficient to produce and certify. 95 RON is roughly equivalent to 91-octane on the anti-knock index currently used in the United States. But unlike 91 premium fuel, 95 RON wouldn't be a niche product reserved just for luxury cars.

Higher octane means the fuel burns slower and is used for higher compression engines found in luxury and sport cars. Lower compression engines (like my old 05 Rocket III and all my current Triumphs) don't have a problem with engine knock (predetonation), so lighter fluid style gasoline works just dandy. Not to mention it's cheaper.

Here's an old thread I found. Try the easiest thing first, lower octane fuel, before you dive deeper into this 😆

Which octane is correct for my bike?

This subject has been argued about at nauseum. Here is a good explanation. Chico

The UK websites relating to fuel octane, including the government standards website and independent motoring websites, all quote the octane ratings as, E10 is 95 octane, E5 is 97/98 octane.

Shell (if you believe them) quote their V-Power E5 is 99 octane. The nearest petrol station to us where we meet up before rides is Shell so that's what goes into my bikes.

Are the petrol companies lying to us? Surely such paragons of virtue would not stoop to such treachery!

On the other hand, whilst I put E5 in the bike when it might be laid up for a while when I know I'll be riding it frequently I go for E10 - and maybe it's just subjective, but it feels like it runs better on the E10 than E5.

Let us know if the lower octane fixed the stalling issue
