throttle question 650v6

[largewayround]

Can someone tell me about the throttle return.

I.e when you twist throttle and let go, how should it return to zero throttle.

should it snap back
or slowly return to zero throttle.

I have looked in manual but Iam struggling to find an answer.

Mine slowly returns to zero, I think it should return a bit faster. Any recommendations on how to get it right

It should snap back, albeit not necessarily with real force. If it does not do so, the cause is likely to be either a sticky throttle tube or lack of play in the two cables. There should be about 5mm of free play in the throttle grip at the edge of the flange next to the thumb. This means that the first 5mm or so of grip movement does not open the throttle at the carbs.

To adjust this, look under the left-hand side of the gas tank. You will see the two throttle cables running onto a wheel on the side of the carbs, with adjusting nuts on the nearer cable which is the one that opens the throttle.

Feel the exposed inner wire for slack. If there is none, loosen the 10mm two lock nuts and turn the left-hand nut (grip side) backwards so the threaded part of the outer casing moves towards the wheel. This will give you a bit of slack which will translate to free play at the grip. Once you have the fre play you want, tighten both locknuts against the housing.

If the throttle tube is sticking on the handlebar you'll have to remove it. If grease has been used to lubricate it, this may get sticky and will need to be cleaned off. Use a light spray such as GT85 or WD40 to lubricate.

As the Pheasant states, the throttle should snap back or at least return quickly.

Often the cause of slow or no throttle self return is the clamp screws for the housing being tightened too much, I'm sure that if you slackened them a little things will be better. I have found that to get the throttle to snap back needs the screws to be loose!

Heres somethig that helps (along with easier assembly).

Of course it could be sticky cables or throttle tube.

Thanks guys..

Here the story so far..

I removed the original grips last night (to fit heated grip, when they arrive)

I did remove the throttle mounting to see if I could get the entire slider off, as I have weights inside the handbars with that little clip. (I was going to just remove the clip and push the weights in slightly so I can fit , end caps.

But found that I could not remove the throttle without undoing the cables.

So I put back together the housing , I probally just over tightened the bolts so thats why it is sluggish returning.

I am going to try again , to remove the slider so i can get those little clips out. (or should I just forget about getting them out)

Looked as someone had put a little grease into the inside of the housing as well , so I will get that washed out and apply some GT85 (love this stuff)

When doing up the bolts in the housing, you say quite loose? Will they not fall out, would you use threadlocker to make them stay in?

Thanks for your help.

I wouldn't bother getting the weights out unless you are going to fit barkbusters 'cos they help dampen vibration.

You need the housing screws to be tight enough to stop the housing turning on the bars. Best bet is to tighten them so you get an equal gap between the two halves at either side of the handlebar. Nipped up enough to clamp the housing is fine. If you don't get the Nylon guides inside correctly installed the throttle will stick. Life is easier of you remove the cables at the carb end first and reinstall them there lasy.

I was going to leave the weights in,(read here not to remove them) but just push them into the handlebars a little so I can put end caps (end caps with a fitting simular to barkbusters fitting) It was the little clip I was trying to remove..

I will have a look later regards releasing the cables from the carb side, sounds like this could be easier then messing with the throttle side.

Thanks for helping, as this is my first transalp it is good to get some fantastic advice on procedures.

Craig,

If the throttles worked fine before you started working on the grips, I'd say it's the nylon insert guide thats not quite re-fitted right, causing a bit too much friction on the cables (Spookily I had this happen last night when test fitting some heated grips to the @).
Unscrew the bolts, removed top cover from throttle cable guide, then wiggle the nylon insert in its normal position, to try and free the offending cable. Whilst the top cover is off and holding onto the bottom half, twist the throttle to see if there is any "stiction". Worked for me last night.
A little grease within the throttle housing at the handle end isn't a bad thing IMHO, but it's not great when between the throttle grip tube and the handle bars.

Just my ramblings.

Cheers Steve

I will have a look at it later and give it a wiggle...

I sure that it is just me , being unsure of what to do, but its a learning experience so will get to the bottom of the problem..

Yes It was fine before I started messing with it..

This is what Iam waiting for...
Funny that they do not have them on Oxfords Website..
Hopefully will cure the cold from affecting my fractured finger.. I was complained to you about when we met up.

SO, I spent a few hours this evening in the shed, had a good look at the nylon insert and I think this is the issue.. I did not insert correctly and it had a little bit of a catchy bit on the bottom, so i filed off.

Anyways,I took the whole thing apart, I removed the throttle slider so I could *Adjust* file the raised bit on the slider tube so my new heated grips would fit.

Cleaned it all up all ready to try to put back together ,tomorrow..



The grips came today today, look great, test fitted the nearside one on the bike, feels good .

SO routing the wiring back to the battery / under seat area.

Is this a Tank off job?? or can I do it with tank on.

[Steve T]

Normally a tank off job, just to keep the wiring tidy. Not wanting to complicate things for you, if the wiring set up for the grips doesn't have a relay in it, think about fitting one and wiring it so that the grips can only be powered up when the ignition is on - please learn by my mistakes

Another point - Make sure that when you've got the new grips on, you can still operate the brake lever without it's full travel being interupted by the heated grip cable.
The 2nd hand grips I was trying on the @ last night were orientated wrong, so they're not being fitted (they are glued to the throttle tube, so I can't move them into a better position )

Enjoy the fettling - great fun innit
