right these are the current issues
1/ front brakes judder when coming to stop eg not progressive almost kadence braking
2/ still runnibg like tractor after red ex put in
3/ front wheel feels like it about to fall off eg go over a small bump and it feel like the wheel has no spacers in it shifting from side to side
now none of these are particularly techincal answers but just the best i can describe
begin the list of answers please ive got 24 hrs left

1/ be more progressive with the brakes
2/ remove tractor engine and insert sv engine
3/ insert wheel spacers will fix problem easy enough.

I saw the pics you put up of who put it together. Frankly, you were askin' for it.
I'm amazed it runs at all.

no sunshine was a valid post just
1/ i am good at braking had plenty of practice heading towards winkers who just pull out on me
2/ no pete and lissa ride the deseil duke mine's an sv :)
3/ done a complete fork swap wheel and all from 1 road going to other so no chance to lose parts
so keep em coming :)
I'm going to go out on a limb and suggest 1 & 3 are probably linked.
Not knowing what you've changed I'm assuming everything so:
1) Forks OK for straightness, oil level, springs & spacers OK?
2) Head races not too loose?
3) All pinch bolts done up to correct torque?
4) Wheel spacer & speedo drive present and correct? wheel axel torqued up correctly? wheel bearings OK?
5) Brakes moving freely, yet bolted on properly?
In short, I'd get the front wheel off the ground and move it round, side to side, back and forth and see if you can find any play or roughness, if so that should point you at the issue.
As per issue #2, "Running like a tractor" isn't really enough to go on, if you suspect the fuel is contaminated with water / dirt then drain the entire tank, including the fuel lines and carb float bowls. Redex is not a product I've got much faith in. Refill with clean, known good fuel. Alternatively it could be electrical, a stuck choke plunger, the carbs being a million miles out of ballance or almost anything else, you'll need to be more descriptive.
Hope this is of some help

joking / not joking / cant tell :confused:
Anyway, Dave, I think jambo gives you a good list of things to start with. It all suggests bearings to me aswell. Did you have the carbs off? Check they are seating correctly (not leaking any air)
Good luck

Ok Dave
you wanted the transplant as you were not happy with the donor. You said it wasn't handling right. Were any of your symptoms above present on the donor?.
We had to transplant the outer bearing race and lack of tools meant it was tapped in using a socket, and a lack of c spanner meant tapping up the nut. having ridden the bike you may have settled the bearing and the head is now a tad loose. Check that.
Brakes well you did them after I left so don't know what you did/didn't do.
Did you remove the front wheel from the forks at any time on sunday. Otherwise spacers etc would have been as the donor bike.
how was the handling when those forks were originally on the S, before you moved them onto the naked and then put them back on the original frame?
Yes folks a lot of this job was to put parts back onto the bike they originally came from.

get the front wheel off and check the wheel balance, if this is out of balance it will cause problem 3 and if its a bad out of balance it can effect your feeling in the brake i believe.
check the carbs for air leaks and the balance. or possible oil levels for the engine.

1, See No. 3
2, Carb Balance may help, YC sorted mine out I've just greeced the choke plungers and that made a difference as well. may help , if they have already been balanced then make sure the bolt used to plug the little hose connected to the carbs (left on to make a carb balance easier in future) is properly blocked, a bit of air leaking here would cause nasty noises.
3, If the wheels have been sat the bearings may be wrecked, try new bearings and check the speedo drive is seated correctly, if the teeth dont align I can see that causing some issues.

Ignore all this Dave, just seen Irsky's post in the Rivvy thread.
Dave, will you be over or do you want me over to yours?
Could get there about 5 prolly. Then if needed, I can pillion you to mine and you can take it. Or come over to mine instead and get it in the garage.
