What brand/model of tires are those?
I got them here:
Right now they are offering free shipping so I ordered a few different sizes to play around with.
Here is some info about the cases:

I looked at buying a GS1100.. or maybe it was a 1000 i can't remember.. but the one i looked at had a 16" rear rim. And dual sport tires are almost non existant in that rim size. So watch for that. I know they all don't have 16" rears though.
Other wise i don't think an 1100 would be much different than the GS750 i did.
i will look into it.
that is awesome took me right there. what a great case and a great idea! and i looked on the specs and the rear tire for a gs1100e 1981 is a 17 and front is a 19. it is starting to look like kismet. i would like a fairing something small and light but offers some protection from buffetting. long mileage days take it out of you. any suggestions?
Rears: Heidenau (tubeless) 140.80H x 17 (Over 12ks so far)
Fronts: IRC GP110 Trailwinners (tubed reversed rears) 4.10S x 18 (Over 25ks so far)
its all a state of mind. my valk lists bayley hazen road, puppy dog ride and some much tougher stuff around plymouth state park in vt, sandwich notch road in nh, rt 630 from canterbury south in new brunswick, and many miles of gravel and dirt amongst her "kills"
Not sure if you were talking to me or not.. but....
The GS750 had a very small gas tank, got pretty poor gas mileage(about 30 give or take a bit), no wind protection at all for longer rides and was just old and i didn't trust it on long trips. Went looking for a used DL1000 and ended up getting a new 650.
There are some aftermarket headlight/windscreen type things available in most catalogs(like for super motards and streetfighters ...etc..) but not sure if that is big enough for what your wanting.
deadly provided a link to a website that had the cases he used on his bike and i think they are dynamite. sorry should have put it in quotes for clarity. i will have to check out the catalogs and see if there is something i like out there.
That is some cool stuff!
Looks like a DRZ400 front end.
Man, I love this thread! I've often thought that a UJM would make a great mild adventure bike.
So let me ask the group here: What do you think of this:
(Sorry about the crappy pic - I was still learning Photobucket when I put this one up there.)
Bike is an 82 Kawasaki Spectre 750. About 24k on the clock. Runs good except for an annoying intermittent electrical problem that causes the main fuse to short out unexpectedly (I'll try to chase that down this winter if it ever warms up enough to be in the garage!) Leaks/burns a bit of oil but otherwise runs great. I rode it to the top of Mt Evans (14,130') in August and it did fine.
I remember thinking that an adventure-bike conversion would be cool but I didn't know people actually did that sort of thing until I read this thread!
Tires are OK but what I'm thinking is that within 6 months or so it will need new ones - trying to find some good mild D/S tires that would work. I don't know the tire sizes off the top of my head but I think the rear is a 16 and the front is an 18, though I'm not 100% on that.
Seems to me the only real "hurdles" would be (a) the shaft drive and (b) the air suspension. Spectres had air suspension front and rear - I assume I'd want to get rid of that as it would be unlikely to be able to take the pounding that an adventure bike would dole out. So how can I convert the suspension? Is it as simple as putting in new springs in the front and finding some coil-over type shocks for the back? I'm also assuming that the shaft will limit the degree to which I can lift it (which is fine - I'm not trying to make a motocross bike here.)
Fenders can be trimmed and/or replaced. I've already replaced the hideous "mini-ape" bars that those early 80's cruisers had with a flatter "Daytona" bar from Bikemaster. It would be nice to fab some brackets for hard saddlebags and a small wind deflector would be nice but I think other than that it's pretty much ready.
Hey, it's even got the fork boots (gaiters) already! (Actually they're cracked but if I'm going to replace the front springs I will put new ones on.)
Anyone else have thoughts on a dual-sport Spectre project?
Picture on Mt Evans. I'm on the left, an army buddy named Stacey is on the right. He's riding my brothers old UJM Kwacker, an 84 LTD 700. Both bikes performed well on the ride which was about 80 miles and took us from 5300' elevation to 14,130'.
ZappBranigan, I am doing a similar project. I am using an 84 Honda Nighthawk. It is a great low mileage, well maintained bike. I just couldn't get excited about the 80's styling. I thought with a little work it could be more of a UJM or scrambler style bike. Like yours, it is also shaft drive. I removed the rear shocks and starting jacking up the bike with a floor jack while spinning the rear wheel. At about 4 inches over stock the u-joint started to clunk. I settled on lifting it two inches in the rear. I was looking for some two inch over shocks, but couldn't find any I liked. The stock shocks were really nice and had lots of adjustments, so I kept them and relocated the stock upper mounts two inches lower on the frame. I am looking for some more aggressive tires. Other than that, it will be mostly cosmetic changes. I will post some pics soon.
Good luck with your project! I can't wait to see it.
Looks like it will work as good as any of the bikes here, all you need is a little imagination. I dont know what size your tires are but that seems to be the deciding factor around here.
How do you do the fronts, though? Seems like the backs are relatively easy - just fit a longer shock or do like you did and move the mounts lower.
I'm not much of a mechanic, and I've never taken forks apart. However, my fork seals are leaking and my fork boots are cracked so I'll need to have it apart soon anyway - might as well do some other work while I'm in there. Is it as simple as just putting in longer springs or is there some other work that has to be done?
What is the preferred style/type for this kind of conversion? I hear the word "Trailwing" mentioned but I don't know what that is (except isn't the Yamaha TW200 sometimes called the "Trailwing?")
EDIT: Gawd I love the internet:
Tire sizes: Front Tire: 100/90-19 Rear Tire: 130/90-16
So now I can start shopping...
I don't think you can lengthen forks very easily. It will involve machining a new part. Either the top or bottom leg. most people adapt a set off of another bike. I just moved mine all the way down in the clamps. For the type of riding I plan to do, I figured stock fork with stock internals were close enough.
If you really have a 16 inch rear wheel, you are very limited in your choices. So far I have only found the trailwing. The other suggestions I got were either discontnued or not available in the U.S. The trailwing you need is the stock replacment tire for the Honda Nx250, if that helps. It is also a tube type tire. I am not sure if it is advisable to use this or not. I am hesitant to try it, until I hear from some other people.
A higher exhaust system would go a long way towards completing the look. But unless you plan to go through deep water, I don't know of any real advantage. I am keeping my low mufflers to make it easier on the passenger and easier to mount luggage.
The 16" rear tire is the problem. If you had at least a 17" rear tire things would be much easier for you.
Im going to do some web searching though and see what can be found. If you get a chance grab a tape measure and check the widths of both the front and back tire. What is the difference between the two?
(If Im guessing right it should be just a fraction over one inch but Im not sure)
The reason I ask is because sometimes you have to try some crazy stuff just to see if it will work. I found these but Im not sure just how narrow you can go on that back rim:
If you do find something that will fit, your safe highway speed my be limited. I went from a high speed rated Dunlop tire to a low speed rated Avon so I never ride faster than about 70 mph just to be safe.
I haven't dealt with these people myself, but I have heard from people that have and they have all been pleased. They will manufacture forks to whatever length you want and I understand their prices are reasonable.
Yeah, I'm discovering that.
I did find some Bridgestone Trailwings in 120/90 16 size, that seems pretty close.
The other thing that concerns me is weight capacity. Is the "Max weight loading" for the whole bike or just for that tire? Because 468lb (the rated max weight for the 100/90 16 you listed) is close to the dry weight of my bike without a rider on board (add ~200lb for that.)
