Givi Windshield Woes

[SaltyDog]

This weekend I'd finally gotten around to installing a larger windshield on the scoot - I settled on the Givi D294ST as it seemed to be the only larger screen available at the time in the US market.

Perfromance-wise, it certainly reduces the wind and wind noise that I was hoping for.  And since I'd already installed the (higher) international version of the seat, it was the perfect height - I can see over the shield without having to cut it down.

However, it did introduce a new problem - it whistles whenever I get moving above 30mph or so.  I'm sure it's not my helmet since I'd changed positions, ducked under the windscreen, even changed helmets to my modular one - the whistling remained the same throughout.

Any thoughts on what typically could cause this?  I've tried running my hand around the top of the windhshield, dash, and mirrors while riding, and nothing seemed to affect it.

Also, for those that have already purchased this windshield - was there supposed to be any install kit at all?   I had to use new grommets around the side bolts, and had to slightly cut the standoffs from the kymco badge/bolt assembly up front so that the screws actually hold it in place.

Thanks

i guess maybe i missed the point somewhere i thought the taller wind screen was so you'd be behind it ,not to look over it.if that was the case why have a taller wind screen ,dunno maybe iam missing something ...and what seat did you install.was this on a kymco 300 i

  My givi sheild went on so easy , useing the gromets off of the other sheild,  everythng lined up perfect,.  the seat I modded it to fit me. raised it 4 inches and moved the butt stop back about 5 inches ,. and I can see over the sheild I think I need a higher sheild to get out of the bug stream,.  but I like the riding position,. much more comfortable,.  and no sliding forward,giving you the feeling of a wedggy,.  now I need a excuse to go on a long ride , the wife gets nervice when Im not home for supper,.

feebleknievel - I wanted the taller windshield so that at highway speeds the windblast coming over the windshield would no longer be hitting the top of my helmet (and creating wind noise and turbulance as the stock screen did), but still short enough so that my line of sight still goes over the top edge of the windshield (so no distortion from the windscreen, especially when it rains).

On the seat, I'd just picked up Kymco's "international" version of the seat while visiting Taiwan since it was relatively cheap, and since it also added the benefit of being able to actually fit two full-face helmets under the seat.  It's Kymco part number is:  G77200-LEA7-305-T01.

de-dee - thanks - on mine, hole alignment was fine as well - it was the metal spacer on the top mounts, as well as the Kymco logo mount height where it wouldn't firmly hold the windshield in place.  Anyway, I'll take another look later this week after I get the scoot back to see if there was another way those could have been mounted.

so the seat thats all it does it gives you enough room to do the Helmets does it help with the seat issue with no leg room thank you

[SaltyDog]

It gives you both:
- Now can fit 2 helmets under the seat, and
- More leg room by having the seat about 2" higher than the original domestic seat. 

For me at 5'11" w/32-in. inseam, having the seat height 2" higher over the original was enough to make the difference in leg room from "unbearable" when ridden for more than 20 minutes, to something that I now can ride for several hours at a time.  Haven't taken it out for much more than 4 hours at a time, so I can't yet comment on doing something like an all day ride just yet.

[feebleknievel]

i know this may sound crazy but did you save the old seat and can you take pics of the 2 next to each other to show the difference in the two not worried bout the under side just would like to see the above side difference thanks

I used the existing hardware from the stock shield when I mounted mine. The shield also went on without an issue. For the rain issue I applied Raincoat to it. I just say an ad for Rustoleum Never Wet. I'm going to go out and get some and see what happens to an old shield.  If I can apply something on a permanent basis instead of reapplying all the time, that would be cool. I don't have any extra noise with the Givi at any speed.

You don't want to use never wet on anything you want to stay transparent. It doesn't dry to clear, instead to a flat haze.

so the extra height comes from the deeper pan up front ok.well you bought it over seas how much is that seat here in the states i do appreciate everything

[mnpugdog]

There is one on Ebay France with shipping it's $300. Cheaper to go get the exsisting seat modified.

Well folks, thanks for all the replies. 
After talking with Givi, they decided to send me a new windscreen, and I'd received it only 2 days from talking with them!  When I installed it, the whistling was reduced quite a bit and limited to only between 30~50mph, but not quite gone. 

Seeking to get it to quiet down completely, and taking into account a comment that the Givi service tech gave me about whistling often being caused by sharp edges, and looking at the bottom (sharpish) edge of the windscreen, I experimented by placing a moulding strip at the bottom of the windscreen.

It turns out it worked. I tried it on the 1st Givi screen - worked with it too.  So, if anyone else has this problem, you could try picking up some door trim protector from an auto parts store and cut it to fit the lower portion of the windscreen (pic attached).

Cheers

Good tip MSL1...

Looks more finished too. Might have to do it to mine too.
