Just curious as I've come across some trouble in another build that doesn't seem to have a support forum like this. Are we allowed to ask in troubleshoot?
In the troubleshoot thread, are we allowed to ask for assistance for non pedalpcb ?

Hasn't stopped anyone so far. 
You will need to provide:
A detailed description of the symptoms, not what you think are causing them. You'd be surprised how many people fail at troubleshooting because they just know what the problem is.
Detailed hi-res photos.
Build documentation, including a schematic.
Tell us anything you did that deviates from the build docs.
A brief description of your tools and capabilities. Do you have a DMM and know how to use it, that sort of stuff.
Make sure that YOU have performed a careful visual inspection of every part and solder joint. Saves us the trouble and only you will be able to examine the board from every angle. Recheck all of the resistors because it is very easy to misread the color bands; we've all done it.
And lastly, make sure you're in it for the duration. It's a bit discouraging when someone asks for help, we invest the time and then they just bail before the job is finished.

Nope, not me. Not really. Very often. Actually I always check the value of the resistors with a DMM before using it for this kind of reason. Doesn't mean I don't put them in the wrong spot of course.

I have a 2008 Triumph Bonneville, one of the last caburetted Bonnies. It's the 865CC engine. I've replaced the airbox with K+N pods and have a Predator exhaust on it. Obviously I've rejetted both main and idle jets and balanced the carbs but still it occasionally stalls when stopped at traffic lights, even when properly warmed up. Any ideas why? It doesn't happen very often but it shouldn't really happen at all. Idle is set at around 1000rpm. It rides beautifully and the pods/predator set-up really gives it a kick in the midrange.

Does it have Lucas electrics? If so, you have your answer.
Otherwise, I'd check the fuel filter, float setting and needle valve.

Hadn't thought of that. My bike is so old it doesn't have PCV. The crankcase on my 1970 Sportster vents to the atmosphere.
Well the carbs are probably due for a clean soon but I think you may have something with the fuel filter. I'll check it when I change the oil, which will be in the next month. I've changed tanks a few times with this bike.
Excuse my ignorance but what is a PCV valve? I don't know if I have one of those. And no, it doesn't have Lucas "Lord of Darkness" electrics.
Funny thing - when I was rewiring various parts of my bike and having to connect to ground I kept having to remind myself that no, I didn't have to star ground to avoid hum...

A PCV valve is a one way valve. Used mainly to relieve air pressure building up from engines internals.
I recall a Dirt Sprintcar I crewed on that was leaning out no matter how big the Pill (Jet) was & it was the spring that holds a Ballbearing in the Breather tube in the Fuel Cap had rusted up & wasn't opening enough!!!
It would have been Catastophic had it siezed shut altogether
Check to see if your Fuel Cap has a Breather that isn't blocked.
I remember looking at Bonnevilles around 2008 or 2009 & the ones they had look like a carburettor but internally it was fuel injection!

Thanks! I have an after-market fuel cap but I'm sure it doesn't seal air-tight. I also have a little filter on the oil breather thingy too.
Yeah my Bonnie is one of the very last carby models. The throttle bodies since are designed to look like old Amal carbs and are quite convincing. Even the current Bonnies - some of which go up to 1200cc - have throttle bodies which look like Amals or something old like that. They're all drive-by-wire now, so the economy is crazy good for such a powerful bike. "Drive-by-wire" is a strange expression and it confused me at first because my bike with it's old-school CV carbs is drive by wire. There are two wires linking the throttle to the carbs - the throttle and return cables.
I sold a perfectly good Softail Fatboy to get my Bonnie and I don't regret it at all. The Bonnie is a great fun bike and much easier to filter on than a Harley.
