Installed a 2" PowerMadd riser and some custom venting today.
The riser came with bolts (only), no nuts to fit the bolts...???? The hex bolts don't fit into the steering cup, so I had to get phillip headed bolts and nuts from the h/w store. Then proceed to file/grind down the bolt heads to get them to fit into the cup properly. Ugh..anyone else deal with that w/ the PM riser? Did I order the wrong PN?![Er... what? o.O o.O](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I'm sorta wishing I'd went with the 1" riser, I think 2" is a bit much...I didn't factor in having to still use the stock cup/clamp, and figured I'd only be going up 1.5" or so (assuming the stock piece is ~.5"??? maybe a bit less).
Ideally I think a 1.5" riser would be best (for me).
Anyway...
I also did a bit of drilling in the hood/cowl plastics, to compliment the guage cage vent. I feel it should help a bit with dispersing the rising heat.

Update 2011/03-23:
Feeling that I still need more venting, I cut a few holes in the side panel, hopefully in strategic locations that won't be laid over into the snow all the time when carving.
I was considering a hole on top of the primary, on that flat shelf, but then feared snow 'sitting' there and melting into the clutch/belt.
I really like how the lower/rear vent turned out, which looks right into the 2ndary clutch. But it tucks in behind the rear/side plastic, so I don't think it'll take on too much snow
I may still need to consider an outer vent, but will see how these work first. I'd like to find some plastic to make a frame, glue screen to it, then pop rivet the frame/vent on.
