View Full Version : A couple more Hornet questions

Morning!
Question 1
Does the Hornet suffer from carb icing from time to time?
If so i suffered a small amount this morning after about 25-30 minutes on my way to work. 8,000 rpm and as much power as kitten suffering from flu.
Question 2
Where do i adjust the idle speed? (it hovers on or around 1k)
I ask this as i had the bike cut out on me a couple of times yesterday when the revs dropped (ie pulling in the clutch). It also happened this morning but i'm not sure if the was Q1 related.
Could this also be to do with petrol starvation?
Cheers guys.

Thats what im waiting for! Bloody loan bike.

Not a common problem so far as I'm aware. I'll ask around, but I don't recall it every being mentioned on the Nest.
Dunno about that glitch............... again I'll ask.....

Dunno - never had to touch mine. I think it's easy done, though. Again, I'll ask! Idle speed should be 1200-1300rpm, something I do know :lol:
Give me an hour and I'll get back to you with the answers :thumbsup:

Nice one!! :D
Quick question:
How would you rate the condition of the bike when you picked it up? Do you think they've been servicing it OK?
There's been a distinct lack of replies over at the Nest so far..... :(

It looks in a good condition overall. A small amount of surface corrosion on a couple of places where water gathers such as the control lever joints.
Everything else looks pretty mint.
Had a reply from the Nest as follows:
"never heard of a hornet geting carb icing buit that doesnt mean it wont happen.
anf the idle speed can be adjusted form the yellow knob under the carbs between the two centre ones"
So, adjust the idle speed and see what happens. Got to say that your "bloody hire bike" comment might be closer to the truth than you might have thought. The dodgy idle speed would be indicative of this. Mine sits at 1250-ish revs after about half a mile. The choke can be switched off after about 100 yards :shock:
The lack of replies to the questions you asked means that what you describe isn't common and therefore peculiar to your bike. Speaking personally, I've never had even a momentary fuelling glitch on my bike.
Hope this helps.

Cheers for that Jabba. I shall go adjust the idle speed and let you know how it gets on.
I think the idle RPM would have to be down to the engineer who looks over the bikes when they get returned to the depot. If it continues playing up i'll get it swapped.
I've a feeling i may hear from the insurance assessor in the very near future to keep their costs down.

Could be the sole cause of the problems? Who knows :roll:
Let me know how you get on.
Hi,
There's been a couple more replies on the Nest, one saying that it sounds like a fuel/carb blockage of some sort (yes, the Hornet still has carbs :D ), and another saying:
"Can't say I know much but after reading a lot about bikes and mechanics....I have never heard about Carb icing on any Hornets... It doesn't seem to be a problem with them!! I would presume that the idle speed is altered by a small screw (so to speak) within the engine...kinda like a cars.........but I have been known to be wrong sometimes.
I used to have an SV650 and I have to admit it wasn't a very confidence inspiring bike, then I rode my exes Hornet and found I could corner like it was on rails etc. I got rid of the SV and am now the proud owner of a Hornet.
I'd never have another v twin!!!"
Well there you go :wink:

Tsk, stiring :wink:
Have you riden an SV Jabba? Do you think they're refering to the rather dodgy SV suspension?
Have you riden an SV Jabba?
Yes. An SK3 ex-demonstrator bike for about 45mins, followed by about the same amount of time on my Hornet (I bought the demo bike :D )
Do you think they're refering to the rather dodgy SV suspension?
Assuming that this is a serious question then I'd have to say "Dunno" as I didn't ride the demo-SV far enough/fast enough to notice any issues, not that I'd have been aware of anything at the time due to inexperience.
Can't comment on the experience of the person who made the comment, but she has owned both bikes.........

Personally i'm a little torn. Prior to the SV i was and inline 4 man. Having ridden the SV for nearly every day since April i can say it has made me a better rider. The engine braking has taught me to power round corners better is probably the main point.
Right, I'm off out now. I shall be looking for that screw before i set off too.

It's not a screw, it's a nut :thumbsup:

Is it easy to access? I couldnt see it......maybe i was in too much of a rush to get home!

Not sure - never had to look for mine 8-[
I'll get the manual and nip down the garage for look-see :D
How did the ride home go?

Right - had a look. Hope that you've got long fingers. And a torch :lol:
You'll need to warm the bike up first (obviously :). 10min ride should do).
With the bike on its sidestand, reach underneath the carbs from the rhs of the bike. The idle adjustment knob is the yellow knurled disc thingy in between carbs 2 and 3. The adjuster looks like it screws in vertically upwards, i.e. the knob part, being perpendicular to the thread, is a horizontal knurled disc (hope this makes sense?). It is the only yellow thing in the vicinity.
Turn clockwise to increase the idle speed, i.e. push that part of the adjuster which is at the front of the bike towards the left. If your fingers aren't long/slim enough then you should be able to push the knob with a flat-blade screwdriver or similar.
The manual says 1300 +/- 100 rpm. Mine's smack on 1300rpm with a fully warmed bike :thumbsup:
If this doesn't cure the poor running then take the bike back to the workshop as what you describe doesn't sound like typical Hornet behaviour.

Well my ride home was the more of the same. But having learned from past experience i did my best not to let the engine cut out on me by keeping the revs up a bit. Still happened a few times.
Right then. I found the yellow cog type nut thing and changed the revs to 1200 on a warm engine. No success. I gave it a few revs and the counter dropped down to 800-900 as before. It came back after a while but was quite erratic, bouncing around 1000 - 1250 (bit of an exageration, slightly slower than bouncing). I repeated this a few times.
So it looks like i'm working from home tomorrow and they can come out and swap the hornet for another bike. Who knows, might be another Hornet.
Cheers for all your help Jabba, it's much appreciated!!! :thumbsup:

That sounds alot like what my teapot used to do. That was all because of very badly setup carbs on top of air leaks left right and centre.
the idle speed on my Hornet does tend to fluctuate between 1000 - 1500 rpm - no idea why ....
interesting thread dont you think folks ? :wink:

Sounds plausible and probable.

Mine doesn't. Sounds like a similar problem?

Just got off the phone with the hire people.....
They're swapping it for a VFR800 tomorrow...... :P
