Trikerbiker, I
have tried a flat 'luggage rack' with a solid tray (I used plywood!) - in fact, so far that's been the most successful thing I've tried as far as stopping water/rain getting sucked up & onto the back of the rider/pillion; and it certainly lessens the 'forward blowing' of the woollen threads along the top & sides of the passenger backrest, so I reckon it hasta be pretty good at stopping the exhaust fumes being sucked up & forwards from behind the Spyder too (but that's a bit harder to confirm!!) But it didn't do much to the 'up & in' blowing of the threads on the handgrips, top sides, & leading edges of the panniers!!
Sooo, I still suspect that the substantial 'low pressure turbulent air pocket' in front of the rider formed by the windscreen & fairing up front of the Spyder will tend to suck exhaust fumes 'up & in' towards the rider/pillion tho, simply because of the fact that for that to happen the way it currently does in the first place, the low pressure area is obviously substantial enough to 'suck' pretty damn hard, & it's going to take a
whole lot of re-directed air or increased air pressure to counter that, even if the flat luggage rack tray does minimise the 'up & over the rear' suction & spray from the back!! I reckon it's gonna take a lot more than just angled Baker Air Wings too, I'm leaning towards ducting from right up front to channel/pipe airflow into the right spots....
As for mudflaps stopping anything but lumpy debris & the bulk of the 'up & over the rear' stuff - they didn't have
any effect at all on spray out the sides that then got sucked 'up & in', & therefore they cannot have reduced the amount of exhaust fumes heading the same way!! In fact, if anything fitting bigger mudflaps
increased the sideways out & up spray & air flow, simply by deflecting a lot of the spray out that way in the first place, where it was rapidly caught in the fairly substantial air-flow up & in so that pretty much all of it ended up on the rider side of the windscreen (or on the rider/pillion! :sour: ). I've tried quite a few different varieties/sizes of mud-flaps too, from small extensions of the existing rigid plastic shield/s to full on 'all the way across the rear of the RT' mudflaps extending almost to the ground & all the way across from the outside/bottom of the pannier right across to the far outside/bottom of the pannier on the opposite side!!
pps:
It's a whole lotta fun, innit?!? People think my multi-coloured thread covered Spyder looks even more interesting than it does with just the tupperware - I've even been stopped by the local Constabulary so they could get a pic of the Spyder in the fraying 'woollie Pullie' (it'd probably drive a Kiwi country boy crazy!! All that coloured wool!! :shocked: )
Have Fun - I know I am! :thumbup:
