For what it's worth:

The other day I bought a new old stock (2012) WR250R for work.

The idle has been way too slow imo, and I also noticed awful backlash running it in through the hills in the on-off-on transition. This little machine is fuel injected like the Tenere - sort of. It has more efi gizmos like an EXUP valve, an airbox vacuum-operated flapper (which most owners seem to hate), coil-on-plug etc.

Finally, I fiddled with the idle speed until it felt right to me (probably a bit fast by most people's standards...).

Miraculously, the throttle transitions smoothed out to be almost as good as a nice carby engine. I rushed home and hit the Tenere with the same medicine ie cranked up the idle to about 16-1700 rpm, from about 1500 (on the tach, so is probably a bit of an estimate, but good enough).

My bike is much, much nicer to ride now, just with that relatively small increase. Happy.

Downsides: A very fast idle on cold startup ie about 2000rpm.
Some owners might find the elevated hot-idle annoying.

Buy a trials bike..that will teach yer throttle control..
Don't just slam it closed , then give it a handful..
Roll the throttle...

I've been having trouble with the bike cutting out when pulling the clutch lately and was going to see if I could find a way to adjust the idle.

Could someone tell me where to find it? Maybe even a picture?

i used to have that problem...until i notched the iddle up a touch.

its a small screw with a spring around it, find the throttle cables on the engine side and you'll see it.

Thanks for the advice. I'm the first to admit I don't know everything.

But... I'll be 61 this year. I've ridden observed trials, club mx, briefly dabbled in road racing and have ridden numerous reliability trials. I work as a mustering contractor, which entails riding over all kinds of terrain at various speeds, often slowly, for up to ten hours a day.

So I do get the throttle control thing, well and truly!

I think the bit that does it for me is the (I will be 61 this year) experience wins every time...

I often think my old man is full of it sometimes but 99/100 he's proven right, and I'm nearly 40 !!!! brilliant.

I will be upping my idle today, and will report back.
