ZL900 bevel drive swap
« on: November 08, 2018, 09:40:57 pm »
I picked up a ZL900 bevel drive to swap in so I won't keep losing drag races to a CBR600 (she's cheating anyway, +4 rear sprocket)

Has anyone ever done this before?  Any special considerations?  As far as I can tell from looking at it it should be a straight exchange.

Thanks!

Ask SISF Bubba....
I have a set of the gears sitting, from a "take out" unit,(can't recall if it was a 900, or which bike) I planned on installing... I affectionately refer to it as the "5th gear mod"  ( i.e., the opposite of the 7th gear mod....)

winter project...  :motonoises: :beerchug: :beerchug:  for COGZilla... to burn tires with....

in combo with the old sets of Ninja cams I have boxed, and the multi sets of 34mm-36mm carbs from yester years of hotrodding back when we began the adventures... should match well, and place the Conni in the correct rpm range to use all that fuel... correctly.

Good to know that it's not a hard no right off the bat!

I think it'll go pretty well with my other mods...

We need more pics of that bike, very nice mods to the fairing and paint. What is the emblem painted on the radiator guard?

 wow, that's a very nice build. If you incorporated some more modern features, brakes, front end, etc it would really be something.

 As far as the 900 / 1000 bevel drive, it's going to lower your gearing by 8%. It's a bolt on. When you order the gasket be sure you get a steel gasket from kawasaki. Specify for a 2005 zg1000. Don't take a paper gasket, they blow out which is why kaw replaced them with stell in 2002. HTH, Steve

Thanks! And thanks for the info! 

I'll definitely think about a front end swap, 8% easier wheelies is probably going to be the final nail in the coffin for my fork seals anyway.   I'd guess any same-diameter forks would swap right into the clamps... 

Like this list?

that's a heck of a list for sure, thanks for that link...
biggest issue tho, is they don't tell you travel, of length dimensions, and wheel/brake compatabilities...

the common upgrade for your bike is to use the complete forks, brakes, wheel, fender... pretty much everything tripple tree down, as they are sitting, from a 1995-2006 model ZG1000 Concours.

the forks themselves from pre 94 to post 94 have a different axle diameter, rim, and wheel bearings, and brakes...

save the headaches, you can pick the whole front end up for cheap, as a unit...

Concours looks good with Ninja bodywork. 
If you don't have time to do it right, when do you have time to do it over.                                                                17" wheels, Nissin 4 piston calipers.1kg Sonic Springs.Cartridge Fork Emulators. KB Brace. Galfer brake lines  Free power mod.

Also it doesn't differentiate between upside-down or rightways up!


Is the post-94 concours front end that much of an improvement?  I'm just thinking if I'm going to drop half a grand on a nice setup, I might be able to swap out everything from the steering stem down from a zx10 or something.  Of course then I'm trading the 80s aesthetic fender for some swoopy thing...  I'll think about it! 

Maybe just heavier oil (mostly so it's harder to squeeze out the seals) and replace the floppy half of my springs with PVC?  That one is surely the most pleasing to Our Lady Frugality but doesn't address the brakes at all.

Yeah, but when you look at those models, and production years, it reduces the inverted fork worry, as they we're not on older bikes...

As for the '95 and up bikes, you can get all those parts for well under $500, and I've bought them for half of that.. so choose wisely...
The newer style does away with the air assist forks, so longevity of seals, and adaptation greatly improves.. the downfall is the rim, wheel bearing, axle size changeup, is a somewhat "les desirable" bearing, as its thinner, and not as robust as the pre 94's... so its a trade off, but then you get the option of a larger cross section front tire, with the newer fork and rim combo... its all trade offs...
The ZG forks can be upgraded greatly, search here for emulator cartridges, and straight weight spring packages... a very affordable alternative, on an old survivor machine like yours.. for certain.

Best of luck,
