I've had the Iron for almost exactly a year. In that time I moved from East Tennessee to Central Texas. Back in East TN I had no problems putting 8-10 hours in on the bike in a day. Stick to the back roads and just tool around at 55-60 mph. Aside from the beating from the lack of suspension and stock seat I was no worse for wear after a full day. I really never wanted to get off the bike. Out here where even the back roads are 70-75 mph it's a totally different story. I've had a couple big days and it takes three days to recover. I mean it's absolutely brutal.
I realize I bought the wrong bike to chase horizons but that's the type of riding I like to do. I just love to see whats around that next corner or over that next hill. Unfortunately when I bought the bike I didn't have my endorsements so I couldn't test ride anything to see what kind of bike I would like and at that time I really had no idea to the type of riding I would like to do. I guess the styling won me over.
So that brings us to the Iron and the fact that I'm stuck with it for now. I don't have the finances at this time to really upgrade the bike or get a bike more suited to the type of riding I do. So in an effort to make the bike more comfortable for these conditions I've decided to see what I could do for the cheapest amount of money possible. Because I'm broke
First on the list is wind protection. I'm fine up to about 60-65mph. After that is agony. So last night I started searching Craigslist for a cheap windshield. I found one for $40. The guy said he didn't have a clue what kind of bike it came from but looking at the picture I thought I could make it work. I really should have tried to get it for $20 because it is very scratched up and has some kind of thin coating that is peeling off. I didn't get any pictures of it before I started cutting but it had some kind of quick release brackets on it that would not have worked on a sporty.
I ran to Lowes with an Idea of how I wanted to mount it and after walking around for about an hour and a half I finally found everything I thought I would need and some stuff that I ended up not using. Total at Lowes was $38. I figure not counting the stuff I didn't use I have about $55 total in this thing. I'm sure someone has done more for less but this is the cheapest thing I've found. I bought two 2" conduit clamps to attach to the fork uppers. I got 2" so I would have enough room to use some rubber to protect the fork uppers. I bought two 1" wire clamps with a rubber protector to attach it to the handle bars. I bought four steel corner supports to attach to the windshield and a 3' stick of 1/2"x1/2" aluminum angle. I bought a 2" rubber plumbing connecter to sacrifice for the rubber to protect the forks and two packs of 1/4" machine screws and some wing nuts.
This is what it looks like mocked up
Here it is after I trimmed it to fit around the turn signals and master cylinder.
I didn't measure it but you can see how tall it is. I actually kinda like how it looks here but cosmetics are at the bottom of the priority list.
I've never ridden a bike with a windshield so I had no idea what to expect. I was amazed through town, the engine sound was so much more pronounced. I really couldn't believe what a difference it made. Heading out of town and upping the speed I was so exited to not have any pressure at all on my chest. All was not well however because at 70-80mph the wind was buffeting my helmet so bad that I couldn't even see. I tucked down behind the windshield and it smoothed out but I was getting no airflow through the helmet. So I sat up tall in the saddle and with my head sticking up into the clean air coming over the top everything smoothed out. So I knew I had to cut.
Here is after the first cut. This was done a little conservatively because it's relatively easy to cut more off but a bitch to add it back if I took too much;)
This helped tremendously but it's still pretty bouncy at high speeds. Feeling around with my hand I could feel the bubble of air. The edge of the smooth air was hitting me right about my eyebrow. I came back and took another couple inches off and found I had a partial can of black elastiwrap left over and decided to use that to try and hide the hardware.
Couple pics of how it looks now.
I still have a nice pocket of air that's not hitting my chest and the vast majority of the buffeting is gone. The biggest issue now is the increased wind noise. I may have to start wearing ear plugs. If I poke my head up a little bit it still gets smoother. I'm just not sure how much further I can go without increasing the amount of air hitting my chest significantly. I'm also not sure if it really needs to be that wide. The pocket of air extends out past my shoulders around four inches according to my expertly calibrated hands of measurement. I'm going to continue trimming it down slowly until I start to get negative results and then stop. Currently it is 16.5" wide and 16" tall from the center of the headlight. This should hold me over until i can afford a fairing. After trying it in the tall configuration I'm pretty sure I wouldn't like a big windshield. All I'm looking for is to take the majority of the pressure off my chest at 70-80mph. I kinda like the look of the Gauntlet fairing...
Got up this morning and decided to keep making adjustments. I decided to narrow it up and I also took another inch or so out of the height.
This was actually pretty good and I should have stopped there. But I didn't.
I was still getting a little buffeting and all I had to do was sit up a little taller in the seat to make it go away. I was still happy with how much pressure was being diverted from off my chest though.
The next cut went a little too far in the wrong direction. The helmet buffeting is completely eliminated however I little too much wind is catching my chest.
At this point I decided I was about tired of fooling with it for this weekend. I decided to cut the top off a little more flat and I'm going to take the cut off piece of the original top of the windshield and make a panel that I can up three inches from where it is now. I thought it was a good time to get everything painted up because I can make any further modifications with it mounted in place. I'm going to get the original top section cut down and get some slots cut in it for the adjustment. Just ran out of motivation today. Here is how it sits for now. Very ugly but even with it being a little too low it's still worlds better than without it at 80mph.
I'm going to play around some more with trying to deflect the air coming from under the windshield.
