Oh yeah! Pete, this is for you (and whomever else is interested). GS450 vs GS500 carbs:



Height wise, they are almost identical. The throttle adjustment screw on the 500 carbs hangs down near the 450's CCT, but doesn't touch it (should be wearing gloves to adjust the idle on a warm motor though.....). From front to back the 500 carbs are about 20mm or so thinner, but I didn't actually measure that. And I said something about the weight difference ......the only scale I have is a digital bathroom scale. The GS450 carbs weighed in at 5.8 pounds, and the GS500 carbs weigh 2.8 pounds. Almost literally half the weight!

Cheers Rich, that's good info!


Now I know my upgrade path if I ever want to do it...  ;)

I've had a plan to upgrade the front end on this from the beginning to run dual disc brakes. I was waiting until I found a great deal on a GS850 front end for my GR650, then take the GS650 front end from it to use on this GS450. Still following all that? Well, it dawned on me that the GR is going to be down for a little while anyway. Why not rob it of its legs now?



And here it is all bolted up. I still need to wire up the brake light switch, and I'm probably going to be swapping the headlight out soon as well.



And other good news - the drive chain came in today, so got it all fitted up as well (ignore the dust on the chain guard):

Brakes look spiffy!
Interesting info on the Mikuni's as well.

 The twins on the front may be overkill, but damn they sure do look pretty. Any good ideas on a slotted/drilled rotor for the front of the 450? I was thinking of taking the tie to do t myself but I may be better off purchasing a nice replacement.

Thanks fellas!

Gary, I swapped the single disc from my GR to a dual disc setup, and people said the same thing. My thought is: you can't have too much stopping power. There is a list somewhere on the GSResources somewhere about what rotors swap with others, but I haven't seen a difference other than the slots themselves. If you want to measure your solid rotor, I can compare it to one of my slotted ones though.

Thanks Rich! I'll see if I can find the conversion on GSR. If not I should be with the bike over the weekend to get some measurements.

Forgot to post this yesterday - finished painting and installing the crash bars. Good old black appliance epoxy!



Today I have a bunch of small stuff to do: brake light wiring, petcock install, replace some bolts on the crank case, straighten up the headlight, etc.

Ok, got a LOT done last night. For those of you not from PA, we got all of this yesterday morning:



My new bolts came in the mail to replace all the JIS screws in the crank covers (don't ask about the Skull / Shell sticker.....long story):



In the same package was a NOS petcock. The original leaked, and I found out why when I took it apart......the internals literally crumbled when opened up.



New clutch cable (along with the replacement crankcase bolts):



Wired up the front brake light switch, adjusted the clutch cable, disengaged the clutch safety switch, and bolted the headlight back up and got this:

So what does any of us do as soon as a project is able to hit the street? Yep.....took it for a ride. It was hell getting out of the driveway with all the snow, and I couldn't take any turns with any actual speed (it was 2am and there is still all kinds of snow / salt on the roads). And this is what happened after less than a block:



The shift linkage snapped. I was in first gear when it happened so I was able to limp back to the garage. I noticed there was just a tiny bit of threads exposed on the broken end and thought "let's see what happens"......



Good enough! Got to rip thru the neighborhood (all up hill from home in case I had to push it back......). Even got it up to 5th gear before my fingers got numb! Woot!

So now it's on the road. I'll be swapping out some stuff here and there, but it's basically done.

Wooohoooo!!!! Awesome stuff Rich! Glad to see her all in one piece and riding :D


Bugger on the shifting linkage but that shouldn't be too hard to sort.


I got replacement heim joints from a hobby store for mine as they were shagged. Just had to take a dremel to the back and grind it off where they'd peened it over on the stock ones, and the hobby ones have a nut on the back so it's an easy swap.


Replacing the linkage should be easy too, pretty stock thread, M6 I think, so shouldn't be hard to find something to replace it with. If all else fails a left hand and right hand M6 tap and a piece of rod should sort that out too...
