Taller Windshield

[Ghost]

Is your windshield to short. I’m 6’2” and have a Roadrunner 150 Touring. The OEM windshield is too short if you are very tall. I was tired of all the wind noise and could not find a taller replacement windshield so I went to the local HomeDepot and bought a 18”X24” sheet of Lexan. The OEM windshield is 15” I made the new one 20”, and used the old shield as a template and cut it out with a jig saw, than sanded the edges. I have had it on only one day, it is a vast improvement, much quieter but does vibrate just a little. The whole thing cost me $14.00 and a couple of hours of labor.

seems somewhat thinner. I am not fimiliar with the material you used, does it flex much at high speeds?

[Ghost]

Its actually a little thicker and is about as flexible as the OEM shield. It is called Lexan Polycarbonate Plastic. Different from Plexiglass, its much more flexible. Ive only had it up to 45Mph and did not flex just a slight vibration in the windshield.

Nice mod.

Did you put anything between the bolts that go through the windshield and the the lexan, or on the other side of the lexan?

Maybe some garden hose gaskets or some sort of rubber washer underneath a larger washer.

That might eat up some of the vibration (or make it worse, ha).

Some of that edge of the car door protective strip stuff might work well on the sides of the windshield to also dampen it.

Good Idea, I will give the washer thing a try. I'm looking for the

car door protective strips but the longest I can fine are 24". The

Roadrunners come with the edge protectors on the windshields

that's why they look thicker. Also hope they will help protect my

cover from the windshield edge.

The strips might not fit exactly, you'd have to do some snipping to get them to fit on the rounded corners.

If the washers don't take out the vibration you might need to taper the top of the windshield a bit more to give it less material at the top edges that the wind can push on.

If you take a look at the original and were to extend that up you can see that it would look a lot thinner at the top than what you cut out.

Of course that would probably be way to narrow for what you are trying to do, but if it was a bit more narrow than it is now, it should reduce more of the vibration due to back and forth flexing at the top corners.

It's really a nice job and I'm impressed.

Nice mod ghost, were you able to get all five bolts back in through the new windshield? I measured mine across on my lance duke and seems that I would need a couple more inches width about 20 inches to secure the outer bolts. Did you have that problem or is my windshield wider possiblly?

[Ghost]

On the OEM windshield I only used three bolts as the outer two would not line up with the holes which did not cause any problems. Yes the new shield is about two inches narrower on the bottom so I only used three bolts again. Probably would be better to use a bigger piece of Lexan but the cost for the next size sheet was $60, more than I wanted to spend.

The vibration is not very bad, I can live it. Tomorrow will be the real test when I take it to work, 5 miles at 50MPH. It has been windy here every day lately and that is what has me concerned, is it going to catch more cross wind. I will post update after a few more miles.

So....what are you doing with your OLD windshield.

I have been searching everywhere online for a windshield replacement for my Bali 150. I took it out once and wrecked with only 38 miles on my scooter. Didn't realize the windshield would be so hard to replace.

I'm about ready to make my own, except the windshield is so cracked that I can't get a good outline. It may not have to be too accurate.

Hi All

I love the new windshield, its great. Cross wind is no more a problem than before. It did cut the wind noise by about 75%, now I can here the engine much better. I still have not found any edge molding for the new shield, busy remodeling my kitchen, bigger job than I thought!

I still have the original shield in case I need it. If the bottom of your shield is still in one piece you can use it for a pattern, it will have the spacing for the bolt holes. You can also get a replacement here >

It is only $30, good price. They have most of the body panels for this model. I think most parts are interchangeable between brands if they look like the same type scooter. I bought a throttle Holder from my local Roketa dealer for my RoadRunner and it fit just fine. Good Luck Caitlyn20

Howdy do,

Nice mod. How did you get the curvature? Hot air gun? Hair dryer? How did you mold it?

[griff10]

Lexan's not heat formable, just have to cold bend it.

Vibration is caused by vortices coming off of the edge of your windshield at different times and at different strength. It would help if you made the leading edge sharper than the trailing edge. This ensures consistent vortex generation all around your windshield and create less vibration. This will also create less annoying windnoise.
