Title: Happy days
Post by: Farmhand on Tuesday, 09 June 2020, 10:39 PM
So I've got a couple of hundred miles on my new 14, all I can say is the engine is everything I remember it to be and then some.
After ten years of riding bmw  flat twins this new experience is pretty addictive!
I've got a couple of issues though the main one being the throttle is very heavy to open making it a bit tricky to tap the power coming out of corners.
I've had the tank off and lubed all the mechanisms but it's still heavy, it snaps closed no problem though?
Secondly the adjusters on one of the shocks are seized, I've been giving them a soak in WD for a few days now maybe they will be ok or it's new shocks or a rebuild.

Cheers for now

I've been battling with the same problem which makes it very difficult to control on small roundabouts without feathering the clutch. Also very snatchy when off-on throttle. TPS and STPS correctly adjusted, taken slack out of throttle cables etc (plenty of info on the forum).

I've just replaced the chain and sprockets, which has made the biggest difference. It's not perfect, but getting there. It is now far easier to roll in traffic at low speed. I found a couple of stiff (but not seized) links. Actual sprocket wear was minimal. How's your chain?

Chain and sprockets are fine, it's just that the throttle is very heavy to open.

Maybe worth pulling the throttle grip off the bars, have a look in there.  Heavy to open but snaps shut . . . .   possibly some wiring loom (or something else) laying across the throttle bodys mechanism?

Try what Col suggested. I found my twist grip to be really grubby on and around the bar. Cleaned that up and she was like a new one.

The only time I`ve had a similar problem, (not on my `14 thankfully!), was due to a simple cable routing issue. The fact that yours snaps shut ok seems odd.

If there was no difference at all when your tank was off, and there is no change regardless of the angle of your bars, i`d try a new cable after checking that the throttle body itself is turning smoothly.

Good luck and let us know the outcome!

It's got me a bit stumped, tank off cable routes are good everything  lubed, I think I will have to dig a bit deeper.
First job is to check the twistgrip as suggested

Slacken both adjusters off on the cables & readjust it, if they are both over tightened it makes the throttle like that.

Worth checking they are both ok though, my pull cable snapped at the right angle bit just above the throttles after about 100k & had been heavy for a while before hand.

Good day  today, I managed to free off the seized suspension adjusters.
I've  now got them sorted.
I have messed about with the cables I've soaked them with WD and adjusted  them and I reckon they are a little better but not great looks like I need some new ones, thanks for the advice

What age is the bike ? It may pay to get the shocks serviced  :whatever:

The bike is a K5,  07 plate, I think you're right I'll get the shocks serviced at some point

The way I see it is this;  What makes it snap back sharpish??   The return spring,  what makes it heavy?  The return spring,  wouldn't think its routing of the cables etc if its snapping-back readily.
Take it apart & see whats what, & either source a weaker or shorter spring or try cutting 1 coil off, trial & error really.

The spring is ok on every other 14, which suggests it's not an issue. I know from experience that having both cables overtightened can make the throttle very heavy & still spring back quick.

Yeh, that makes sense.

I've got some lube on the cables and re-set them,  it seems ok now cheers for the advice.
