A few Questions

Just trying to work out wether these are little traits of the bike or things I need to sort if anyone can shed a bit of light for me ..

In slower corners the bike seems to want to turn in on itself .. Do they all handle like this? Is it something to do with the weight of the bike? feels wierd.

Brakes judder quite badly under medium/heavy pressure .. I've stripped the front end and cleaned the calipers .. the pistons are all operating .. the discs don't appear to be warped or owt but it's still doing it. Pads are a bit worn and I'll pop a new set in .. are any more suited to the bike than others?

Fuelings not that great at lower revs and it pops if you hold it around 3-4k for any length of time. The pipes are standard but they sound a bit throaty (may have been cored?)

There's a fair bit of vibration at higher motorway speeds but not with the boxes on and loaded.

Yes

Headraces?

Mine was pretty smooth from memory

Yep I sold mine as it gave me a tennis elbow feeling for days after a ride. Unless you were balls out, in which case was fine

Mad days on my old one....

There are no slow corners. Go faster and it won't tend to fall in the same.

As Paul said headrace bearings but I would still go for warped discs.

Fueling really needs setting up properly by someone who knows what they are doing. Bare in mind it all works better if the valves are correctly adjusted, leak test done and the correct cans/system installed.

cheers guys

doesn't seem to be any movement in the bearings (at a standstill)

will pop a different pair of discs on and see if that makes any difference.

It does pick up in the corner when you open the throttle .. nice for alpine roads .. not so great on greasy industrial estate roundabouts

Where does all the extra weight come from on these things ??

apart from a few hoses on the motor It doesn't apear to have anything my SS hasn't .. apart from a bit of extra suspension linkage, a fuel guage and a clock.

Is the clock a grandfather clock hidden inside the fairing?

Reckon the tank is meaty but think geometry different so feels more top heavy. They go when you push them tho, and you can even scrape panniers without crashing if the camber is right

Mine had terrible electrics, was pretty uncomfortable, always kept having niggly issues, was a bugger to work on because of the plastics and lacked a little in ground clearance...but not much cold keep with it or leave it behind on sub130mph rideouts and theres nothing as fun as slamming it into a 90+ turns and having sparks coming from the stand

Until it digs in... Gulp!

Handling, will be a lot slower than your SS, check fork setup, tyres and maybe try dropping forks in the yolk, I did 5mm on mine and it sped things up alot.

Recommendation is also to raise rear ride height by, on the center stand dropping the rear wheel until it nearly touches the ground.

Discs, try spinning the bobbins to make sure they are free.
I think you'd need a dial gauge or take the discs off to really test if they are warped.

cheers fella

Did dropping the forks cause any ground clearance issues?

I didn't know the rear was adjustable for height??

No clearance issues for me - but I freely admit to not being a quick rider.

Have an ST4s, workshop manual:
