GS750 / GSXR Build

Hammyboys? What's that? :)

I've not put an real time on a stock fairing or this one to know the difference yet....!

Now I'm thinking of either sorting out some new bars for the clipons or maybe going for one of these guys instead & switching to that setup... Might actually give me an extra inch of rise that might be nice to have...

Anyone got any chain guard suggestions? Joe what was that one you used on your 1100??

I'm guessing that... although it doesn't feel hugely different to my friends stock one with the 120r Avon on it.

The stability, increased grip, and line holding ability of sportbike radials really becomes apparent once the bike gets leaned over hard. It really does feel like you have more real estate on which to lean the bike which in turn improves your cornering confidence. Add to the equation that radials are more compliant so they don't hop, skip, or jump over road imperfections when cranked over and it's a nice package.
 
PJ after my first real ride today I can completely agree. I went up & down one of my favourite local bits of road about 6 or 7 times...

This bit of Palos Verdes drive east heading up from the ocean:

http://maps.google.com/maps?f=q&sou...731407,-118.331895&spn=0.018523,0.038581&z=15

Lets say I wasn't "knee down" but the way this bike is set up I was the closest to it I've ever been already I would think :D. The 1000G would certainly have touched the centre stand at that angle, the skunk would prob have made it round but I wouldn't have felt so good about it!
I've already scrubbed the rear tyre really well to about 3/4" from the edge & you can see I've run right over to under 1/2" in places. I wasn't pushing really hard as new bike, new rubber

It feels really planted, very confidence inspiring. Engine feels strong too, as long as you keep the revs up past 3.5 - 4k. Rear suspension feels a little overly hard, unfortunately I can only do something about that with a spring change as I'm on bottom preload. I could back the damping off a bit but the shock only has rebound adjustment. Maybe I'll get Chef1366 to come sit on it for me, break it in :D Front suspension feels stiff but pretty good, I can back that off a bit on the preload adjusters if I need to.

6 pot brakes on the front have awesome power.

I'm now using the clipons with a 2" rise on them (rather than the 4" on the ones that snapped), I have them laid back a way & they feel pretty agressive still but "ok" at speed. Maybe I'll need to make up some more or change to risers & full bar or maybe I'll just get used to them. Rode for about 1.5hrs today with no real issues, a little stiff when I got off...!

I've done the "quick turn" throttle mod on this bike & I must say I'm not sure if I like it. It makes the throttle heavier than I'd like & affects the progression of the roll on in a turn... it could also be that I'm not used to the angle of the clip-ons yet. They command a more "elbows in" position than I'm used to.

Next for a carb sync & then to sort out this charging system...

Rear brake kit:

BikeBrackets.jpg


I have to use an 850 / 1000 caliper with a couple of mm ground off to clear the wheel hub as the stock 750 has a connection for the banjo out of the side which doesn't work as I'm running it an inch or so closer to the swingarm, 850 one is connection out the back which should work fine.

Where did you get the special brake torque arms from??
 
Had them made.. I have a couple of different ones left over if the length is right to work with what you need.
Other than that people cut the end brackets off and weld onto a longer tube with a bend in it....
 
Went to see Nessism today for a carb sync... Got that sorted and also sorted out the charging system. Turned out to be a duff stator.

Found some movement in the front end so. Not the head bearings could be the forks or the 17" wheel conversion which use sleeves on the axle I guess. Time to jack it up again.....
 
Salty Dan's 750 is awesome.:D Those soft radials look killer and the engine sounds amazingly tight considering it's somewhat unknown past. As expected this bike has that "Salty_Monk look", which is to mean a smattering of strategically placed flat black and custom made parts. Highlight for me are those 6 pot brakes - if they work half as well as they look they will make our GS brakes seem like a bicycle coaster brake. Gotta get me some of them.:D
 
hey i was just wondering what year and model ducati that shock came off of and also how much work it took to make it fit?
thanks

Weston
 
98 Monster 900. Showa. No real work, you have to relieve the outside of the top eye with a file but you don't need to take off much material.

Length is same as stock 330mm but slightly less travel. The Ducati spring is way too hard (just about started feeling right with 170lb of nephew sitting on the back!). I am going to put the stock spring back on soon.

I was too late noticing this thread. Nice bike. I was going to suggest using the 1980-81 emblems on the side panels if they still sell them. Always thought those looked nice, too late though, oh well.
 
O.K., read the whole thread, some simple questions:

1) was that the 1st generation GSX1100 front end?
2)Did that have a 17" rim?
3) What did you use for the rear Rim?

Thanks, and I have looked but can't seem to find these answers. It seems like something I may be interested in doing, but I don't want to drop a lot of money on parts that don't fit and nobody else wants. Also, is that the stock swing arm? The rest I can see what you did, calipers, etc. but there are some early Generation front ends on EBAY now, knowing which one is the right one would be a great start. What years am I looking for, the 1st and 2nd year only? ;)
 
What's considered a 1st generation GSX1100 front end? just curious, there are so many out there. Also, the rear swing arm thing still has me wondering, was that changed? Maybe it's too late to ask these things, but seeing how none of these upgrades affected the original bike, it would be interesting to do, and something to do with my son. I just don't want to throw money at it by buying the wrong parts. :)
 
It was the original swingarm but the 170mm tire & the 5.5" wheel were hard work to fit. I would go with a 160 on a 4.5" wheel if I was you. From memory there is one that will fit the standard GS sprocket drive (or possibly the GS500 sprocket drive, I can't remember) which makes it narrow enough.

All the info is on here somewhere, you just need to learn to work the search tool. There are 3 or 4 builds based on this bike. It's not easy sometimes but there is a tutorial for that too (or use Google site search). :)
 
I appreciate you taking the time. This is something I should have done a long time ago. Time running out, I'll keep the bike bone stock, like the day I took it out of the crate. Thanks for responding. :)
 
What I really was wondering is was there a way of getting radials on the old ';83 GS750ES. I don't think that's possible. The bike handles so good stock though, it would be interesting to see if it handled better with Radial vs. Bias Ply tires. ;)
 
I tried to do that too ony 1000. the 1150 wheelset was wide enough for an Avon 140 radial that they used to do but they discontinued it now.
I never did get it on the bike in the end. Was an abandoned project for me.
there are no stock wheels that are wide enough.
my guess is that the radial will just highlight any flex in the frame anyway probably…
 
I've read that somewhere else too. To be honest, my '83 GS750ES doesn't seem to flex, and I've flipped that bike pretty hard. ;)
