5twins explained that on CV carbs, foam is better than pleated, in the pod department. When 5twins speaks, I listen. Also, there are numerous posts on the forum from dudes installing UNI or other foam pods, and experiencing an amazing improvement.
So I installed UNIs, and took the bike for a spin this cold Canadian morning. Yes, there was a noticeable improvement. Bike idled pretty good and didn't stall out once at a light. Don't think it was just in my head that throttle felt smoother. (And even if it was just in my head, it still makes me happy.) Less spluttering and popping at random moments.
Here's the "but." I still found that after the bike warmed up, idle speed at stops ran high. Better than with the K&N filters, for sure; but I was hoping it would disappear.
When I first start up the bike, idle is low: around 1200; maybe less. (I installed those little chrome speedo and tach units when I fixed up the bike 15 years ago, and somewhat regret that decision. They ain't the most sensitive and/or accurate things in the world.) Anyway, low idle for the first while. That's where I was experiencing stalls at stops.
Then, after either zipping out on the highway or just giving it time to really warm up, idle seems to go up and stay up. With the K&Ns, it was up over 2000 rpm. With the UNIs, it hovers under 2000; but not back down to the recommended 1200-1500.
I don't comprehend this phenomenon. If any of you fine fellers do understand - and care to share your wisdom - I'd be most appreciative.
Gracias, Amigos!
