I've posted this on the Dame Edna site so apologies if you've already read this.

We had a nice run out to the coast today, the weather was better than
expected but the Trophy misbehaved a bit.
At normal road speeds the bike ran pretty much as usual although if I
held a constant throttle I could feel a slight throttle on / off
sensation.
At very low crawling speeds (not curb crawling I hasten to add) or at
tickover, the revs would fluctuate and several times the engine
cutout. I washed the bike this morning but I don't think that would be
the cause ?
I've added Redex to the fuel and squirted WD40 into the fairing gaps
in the hope that tomorrow it will be back to normal when I start it
up ;-) . This I know is very unlikely . . . but you never know ?

Any ideas as to a possible fix, plugs or similar ?

Cheers.

Hi Andy,

Silly question, but....are you sure that the choke is all the way off? I've noticed that even if it's on slightly, mine will idle very poorly and stall at times. By now you've probably concluded that I speak from experience. I fiddled with the idle adjustment for about 15 minutes one day before finding the lever on a wee bit.

Hope this helps: Jim

Thanks Jim, I'm pretty sure the choke is fully off but I will double check.
By the way, which spark plugs should I be using in my 02 1200 Trophy, the Haynes manual suggests NGK/DPR9EA-9 but online they show as NGK/.DPR8EA-9.

I'm embarrassed to admit this but you were spot on Jim, the choke was slightly on, I was convinced it was fully off.

Thanks for you knowledgeable fix. :-D

Hi Andy,

Glad that it was an easy fix. I'll have to tell you the tale of my 1970 Tiger, sometime. I'm sorry, but I don't know anything about the plugs. If I find anything out, I'll let you know, but I'm sure others will be answering the question before me.

Happy Riding: Jim

Andy,

The NGK/.DPR8EA-9's are what is recommended in the factory service manual, but if you look in your owners manual, it list the NGK/DPR9EA-9 as the plug to use. I am trying to remember if I just heard it at the dealership or read it somewhere, I was thinking my first service manual I bought in 1996, but they referred to the 8's as the winter plugs, and the 9's as the summer plugs. The 8's run a little hotter than the 9's. For NGK plugs the lower the number, the hotter the plug. I can't remember for sure, but I think they are the only plug maker that numbers that way. If I remember correctly with AC/Delco and Champion, the higher the number, the hotter the plug.

I have been running the 8's in both my bikes without a problem. They are what my dealer puts in the bikes they change them in and I didn't see any reason to change. I keep them in the Trophy for the fact that when the weather turns cold, that's the bike I ride and it doesn't get hot enough consistently around here for me to worry about running one heat range higher in plugs.

I would just check the plugs after you have some miles on them. If they look nice and clean, the carbon and other deposits are burned off, you got the right plugs.

Yes eventually I did manage to find some plug info re 8's and 9's and it ties in with what you stated above :wink:

Did I mention that I'd been out and bought new plugs, feeler guage and a socket set before discovering the choke fix ? Never mind, they'll keep til next time. :-D

One can never have too many tools, Andy. Been there, done that....
