Looks Great!

Only problem you may have.....is there may not be enough motor for the suspension. :-\

Pardon my questioning... but Traveler... what do you mean by "not enough motor for the suspension"?  I don't understand?

Cheers!

meaning.....the motor will be maxxed out at redline, and the suspension won't even be breaking a sweat. ;D

Gonna want to build the motor shortly, as a stock 736 ain't gonna cut it. :-\

This suspension is gonna want 120 Horsepower, not 70.

I just weight the bike.... 160 kg (348lbs) without oil but with 10 liters of gas. I also measured the wheelbase because it raised some questions earlier: 1520mm. So something like 60mm over stock,

It seems like this bike is going to be fun even without a hot rod engine  ;D

I just saw this thread and also noticed the wheelbase looked long.  I did an '81 CB900F with a CBR600F2 swingarm and had the same situation.  Smooth riding, but feels a little heavy in the turns.

When you say "heavy" do you mean that it slowed down the steering some?

Yes. The 17" CBR wheels also lower the bike a lot compared the to stock 19" front and 18" rear so it has a bit of a sled feelings, if that makes sense.  The answer for me is to notch out the rear axle slots in the swingarm and mount my shocks higher.  All that aside, modern suspension sure does look sexy on these old beasts.

I think I speak for everyone following this thread when I say "GET ON IT!!!!!!". I'm anxious to see you blast up the street on this thing, I wonder if it can pull a wheelie with the weight loss plan you gave it.

That is quite sexy, but doesn't it look like that chain's gonna be rubbing the top of the swing arm?

It doesn't touch the swingarm. When i sit on the bike there's more room in between. But just to be sure there's a guard on the swingarm (not in the picture).

Wow beautiful. Im at 12 o'clock right now after reading this thread, that is the exact suspension setup that I want to attempt on my bike this winter

Maybe a roller guide for the chain? It looks a bit too close and with suspension travel, especially on the rebound that chain will touch the swingarm. At least it looks that way as it sits in that last quoted post picture.

love your build ...and I'm going to keep an eye to she how she comes out, but when you cut the back of your frame and that brace is gone under the seat, will it flex now ?... I did it to mine but I welded a piece for the battery box and what not. sorry I'm no pro but was just wandering about that .

The flex there is only really a problem when using the twin shocks that come standard, in that application the rear frame only holds the seat up....

We will see if it's a problem or not. If it is, i can adjust the height of the back (= angle of swingarm) with the dogbone in the linksystem. I wanted it to be as high as possible for a nice head angle. But i can achieve the same thing by lowering the forks, so no problem...

Exactly! It will only have to hold my 70 kg's.
