2001 katana front end on 82 GS650?

[ajkammerer93]

Hi folks,

Unfortunately I was in a collision recently and my bike ('82 GS650) is in need of a new front end. I kind of have a cafe type thing going on with it already. I've lowered the front, have clip on's on it and some other mods. I know that's not the most popular style around this form, but anyway.

I have located a front end from a 2001 katana and was wondering if anyone has any experience swapping out front ends like this and can give me some tips/advice?

I know its going to lower the front of the bike. As long as it's not too extreme I'm okay with it, as I had already dropped the front end a few inches before the collision.

Thanks all! Look forward to the comments!

So you are going to take entire front of katana, dual brakes,etc? Triple tree? Do you have the opportunity to measure the katana parts for comparison to your damaged forks?

I did on my 1000g great stuff, same axel diameter and what not but the 4 pot calipers wont work

katana wheels and front end on '79 gs1000

katana wheels and front end on '79 gs1000

I just picked up a '97 katana with black cast wheels to swap in place of the gaudy purple wheels on my '95 Katana. but then I was thinking maybe put the '97 Kat front end with my purple Katana wheel on my '79 gs1000 (just for ****s and giggles, my gs1000 already has nice cast wheels and dual disc front). Can anyone comment is this an easy swap of the complete front end up through handlebars (will they clear and fit comfortable with my stock '79 fuel tank). And then assuming the purple wheels are OK on a Black bike (maybe, hehe), what do I do to mount the katana rear wheel on my GS1000? I'll follow this thread and maybe post my own and hopefully we can work together to fulush out the issues..

I just picked up the front end from the katana. Forks, wheel, brakes, triple clamp, everything.

So far I took the top bearing off the GS stem and put it on the katana stem, and it seems to fit in there just fine. the stem is about the same length. I cant seem to loose the lower bearing from the GS stem though. The GS has like cone type bearing and the katana is ball bearings. If I could use the upper and lower GS bearings on the katana stem that would be ideal, but I'm not sure how to remove the lower bearing without breaking anything.

However it seems to work okay with the katana lower and GS upper. One think I noticed already and sort of figured would happen, is the stops are going to need to be adjusted otherwise the forks are going to hit the tank. Either that or maybe I'll take a hammer to the tank and do some from end indentions. Not sure I want to do that or not yet though.

Will update as I go. Any tips on loosing that lowering bearing from the GS stem would be appreciated.

Look on my build thread "mild cafe" i have my 97 kat front swapped on, i had the gs 19 on and the gs speedo drive but i did not want to make custom brackets to run the less than adequate gs calipers. I ended up running the kat wheel with the 4 pot calipers. You will need to make steering stops as the bars will tap the tank. As for bearings theyre the same pn. I literally dropped the kat front in as if it were factory. With proper spring rates these 41mm forks were very desirable for me because i prefer conventional style forks over usd or up side down on a classic bike. Good luck, don't over think it

Hi folks,

Unfortunately I was in a collision recently and my bike ('82 GS650) is in need of a new front end. I kind of have a cafe type thing going on.....tips/advice?

so your bike tried to commit suicide before it became a full on cafe racer....... I love it.

Glad you are OK... but had to make the joke.

 

[ajkammerer93]

hillsy, That's what I was trying, but I stopped short of actually getting the thing off because I was worried about breaking it. But I'll push it a little further. Thanks for the graphic!

Thanks brandon! Can you drop a link to your thread? And yeah, it looks like the steering stops are going to the most complicated part of this swap.. Which is great. lol

Blue falcon.. lol I was waiting for the cafe hate to start coming out.. lol. It's not really full on cafe, it's kinda more of a rat bike, but yeah. I guess it's getting closer to that. Thanks.

 

[ajkammerer93]

This is not the best pic to show the bike.. but so you get an idea of what it looked like fore the accident.

I didn't get too detailed, but i can tell you youre either going to run the 17 with cat brakes or making brackets for the gs brakes and run the factory wheel.. rearsets would top off this swap very nicely

 

[ajkammerer93]

Thanks Brandon. Plan right now is to run the kat wheel and brakes. Was thinking about swapping rearsets.. Recommendations?

 

[thebrandonbeezy]

Theres ones made for our bikes dont remember the name, but i do remember theyre expensive af. Im going to run first gen r1 rear sets cause theyre about 75ish on ebay and the brake master is mounted on them instead of the frame so it simplified the systems

 

[thebrandonbeezy]

Are you shaft drive perchance?

 

[ajkammerer93]

I am yeah. 82 GS650L shaftie. So I'm actually super interested in your rear wheel swap. I haven't though too much about that yet. I really want to run the 17" kat wheel, but I do agree it will look kind of funny with the stock rear wheel. Plus it would be really nice to have matching wheels..

Are you shaft drive perchance?

 

[thebrandonbeezy]

That and it rides funky with a 2.5 in the back and a 3 in the front, i went with the vx800 because it had the same definitions as the kat rear wheel. Youll need the katana brake caliper, brake stay, and caliper mount. Youll need to get creative with shiming the the caliper and caliper mount at the axle end. If you do it let me know, help any way possible, also busa1300 is working on the madura spoked wheel swap as well. If your interested in spokes.

 

[ajkammerer93]

Spokes would be kind of neat. The vx800 drops right into the GS hub? Do you have to modify the swing arm at all? Or just the caliber mounting?

 

[thebrandonbeezy]

I'll post pics in a sec, no cutting or modding the swingarm

 

[ajkammerer93]

Cool man. Stoked to see it.

I'll post pics in a sec, no cutting or modding the swingarm
