I've gone thru a few different setups with my triumph ITB setup.
At first I used some UNI foam filters without a velocity stack under them. This filtered the air but didn't handle lean pops very well - the foam ended up splitting near the flange on 4 of the 6.
Next up I tried these motorcycle v-stacks with metal mesh filter cap on top. Cheap junk. The caps with the mesh kept blowing off.
Moved on to the PMO rain hats and K&N with the weber style stacks. This worked great but the mounting required me to use these things:
If you look closely, they aren't round but oval and add another restriction point before the throttle plates. I can actually feel a difference between the motorcycle stacks (no filter) and the rain hats. Top end felt sluggish with the PMO setup. Disclaimer - the PMO kit is nice and probably doesn't have this issue when used with their carb or ITB kits.
So I'm ready to try something else and would ideally like a velocity stack that has a reliable mesh filter on top. I need the throat to be 52mm or 2". Prefer height to be 3"-6" but not too picky here. I'd also prefer the set of 6 to be somewhere under the $200 it i could.
Anyone got anything similar they could recommend?
