past the maximum compression of the fork, near the lower triple tree.

Ok, I know exactly where you are talking about. Wonder why they didn't just chrome the entire thing. Oh well.

Thanks

On the "f"s they did. But on the "K"s because of the alligator boot they didn't need to. Who would ever want to take that boot off anyways.  ;)

The Jacwal fairing is a 2 peice fairing. The one on ebay is missing the top handlebar mounted peice and is very hard to find. Like shown on this bike. They aint the prettiest fairing.

A bit before my time, but I'm thinking it looks like Flash Gordon!!  ;D
Sure it's for sale! How much you ask?? Well, how much are you willing to pay??? Now triple it, that's the price!

I've had pretty good luck with my Shoei FM-2 Fairing on my CB750, I got the taller windshield on it and it sure is nice to ride behind. I had a CB550 years ago with a Shoei FM-2 on it with the lower windshield and I really liked it, it took the wind off my chest and I thought it made the bike look racy.

Alan F, that sounds interesting, would you mind getting some pictures of your rig?

Thanks,

Brandon

Sorry for taking so long to get some pics for you, Here's my 92 NH'CB750" with a national cycle F-16 Tall Touring model and the struts or stays that I'd made for it.  It's all held together with stainless hardware and there are black rubber washers between the stays and the shield.  I've padded between the clamps and the fork tubes with a chunk of inner tube to avoid any scratching.

Alan, thanks a ton for the pics!! That looks really nice, and well thought out. Not sure if I will get one as long or if I will go with the shorter F15 model, but either way, I have a better idea of how to brace it if needed.

Thanks

They do come up used on ebay from time to time, I picked mine up for $59 shipped.  It had a scratch on it and some pits from the PO, after 5 months and about 4500 miles it has a few more.

Yeah, I think I have seen a few. I'll have to keep my eyes open, I'm on eBay all the time looking for deals  ;D

Thanks,

So the F-16 will fit any bike with a 7" headlight right? I found a decent deal on one on eBay I am gonna try for, but want to make sure I don't have to worry about sizing or anything. It looks identical to the one you have Alan, so looks like I may be using your bracing idea after all  ;D

Thanks,

Brandon

Mine fits fine on both my Hawk GT and CB750 (7" headlights). Its the shorter one, but that shouldn't make a difference as far as mounting. Its a very clever mount design, clean with no clamps on handlebars.

From the looks of the pic that Alan was kind enough to post, it just mounts on the headlight via the bolts that are already there correct? I believe the one I am looking at is the taller one like what Alan has, so I will probably end up doing something similar to his rig to keep it from flexing and being noisy, if necissary. Gotta win it first though  ;D

Thanks all!

Yes those are the two attachment points. Then there is an adjustable device that leans against the fork ear on each side, so you can set the angle, and gives it 4 points. Wind pressure is the only thing holding it there. Some applications may have it bolted in place. Very stable nevertheless.

Alan's fix for the taller shield is a good one.

Well, just placed my bid, so keeping my fingers crossed. I'll try it without Alans fix, just to see how it behaves, and if necissary I will do a variation on the design Alan has.

Thanks again,

Brandon
