Title: Heated grips not staying stuck
Post by: Jon the mow on 22 March, 2020, 06:45:37 PM
When I bought my bike in December, I asked the dealer to fit Oxford heated grips, when I eventually passed my test in February I took it out and the LHS grip started moving after the grips had been on for a while, so back in it went.yesterday I spent a fabulous but chilly day in Brecon and the same happened again.
So does anyone know which glue they should be using, and seacondly, can you tell them for me, coz they HATE being told how to do something properly 🤣🤣🤣

Superglue. But the left grip glues to the handlebars which are nice shiny chrome, so the handlebar needs to be ďroughenedĒ slightly to give a key and cleaned with a solvent before applying the glue then sliding the heated grip on. Works for me. Easy job to sort yourself. Just make sure no glue drips onto any of the bodywork or tank.

LHS grip is the easiest side. If you can pull the grip off donít ride the bike until itís sorted because it might come off on a left hand corner. You donít want that. Iíd email Oxford for the right sort of glue. Also be careful not to snap the wiring into the grip.

This is a common issue: heated grips melt the glue underneath and the grip starts to slip. It occurs mainly because the glue that oxford give out in their kits is inadequate. If you want the original stuff then I'm selling what they give you in the box:

https://www.ebay.co.uk/itm/Oxford-Heated-Grips-Accessory-Pack/283617559797?hash=item4208ec84f5:g:H3IAAOSwRA9dgWML

Outside of that any strong super glue should work, but for me I use this gorilla glue specifically. (https://www.google.com/search?q=gorilla+glue&rlz=1C1CHBF_en-GBGB821GB821&sxsrf=ALeKk03xA4gmy5jjrkvAXCBgQn-CB6fJ0Q:1584908321734&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiRzJLM867oAhXCQxUIHaq4DhQQ_AUoAnoECBYQBA&biw=1920&bih=937#imgrc=DC0-URei5yzD8M)

To ensure a good long lasting set I'd advise being willing to leave it for a few hours afterwards (with gorilla glue, that is -- anything weaker and I'd advise longer).

For the L/H one remove the bar end and heat the grip up with a hair dryer then wiggle it with brute force so it comes off the bar. Clean up any left over glue with brake cleaner and some sandpaper or alike. The cleaner the bar is underneath the better the new glue will set. Key point here is not to allow glue of the L/H grip to contact the switchgear otherwise it will become stuck and cause headaches down the line. Gorilla glue expands so be sure to cut the excess of after it dries and hardens / seeps out the end.

For the R/H one you'll have to remove slack from the throttle cable and remove the cables from the throttle tube inside the switchgear. After that you can just glue throttle to throttle tube and then re-fit and adjust throttle free play as required. Making sure you don't snap the return cable is key on the CBF -- I know you don't mention this one but if you've used the same glue on both sides then you'll find the throttle grip twisting freely of the throttle tube eventually. I've had it happen to me and it makes for an interesting ride (on other bikes).

Fitting them on this bike isn't that hard due to battery location. How close the battery is to the bars makes for a hard job when it comes to routing the long wiring, if anything.

Edit: before you remove the grip make a note of the exact position of the large portion of the grip (as seen in the photo from google below) that resides right by the switchgears to avoid problems with other controls and cable routing (particularly important on the throttle side):

I think Iíll give Thunder Road a chance to use superglue/ gorilla glue.ibet their worried about product warranty, so persist in using oxford glue. If they refuse to try an alternative, Iíll contact Oxford, I did try to get end weight off, but couldnít move the Philips screw for love nor money.
Thank you all for your helpful replies, itís great to get advice on this and other problems Iíve had, much appreciated, j

Thunder Road being the dealer that sold you the bike back in December, I assume?

Their good guys if they take it in and not charge you, but on the other hand its a ten minuate job (minus waiting for the glue to dry) at most so would be interesting to see a figure placed on such a simple job.

Pick up whats known as an impact driver. Halfords sell their own in a case with bits for not very much. Hammer on the end and free's up stubborn screws etc. Bar end weights are not uncommon to be tricky, but don't really need tightening up all that much. Think most the problems are caused by ones that haven't been undone in a long time. Not really ever read of them being over tightened. IIRC the halfords one can be twisted anti clockwise and clockwise so is something to check / set before using. These tools are useful for a range of tasks. Other brands available, just passing on what has worked for me.

If it happens again I wouldn't bother taking it back, or just ask them to use Gorilla glue from the go as "oxford" glue is nothing more than standard superglue with their name on the packet I assume.

Contacting Oxford would be a waste of time, I'd just use something stronger than whats supplied and not think twice about it.

Perhaps stick some cable ties under the seat to clamp the grip in place if you're out again and it occurs. Bit OTT but suppose cable ties can save you in multiple ways when out if something occurs.

Best of luck, and again keep an eye on any movement of that throttle grip indepdant of the throttle tube. The CBF can bite at the best of times. Its no sports bike, sure, but can easily catch someone out.

Just keep an eye on how long you leave it at %100. On days like today (8-10 degree's) I had it on 50% for a bit, and as low as 30% at times. Keeping it right up there may be nice but can contribute to slippage as it warms up outside (no proof, just personal opinion).

Last time my left grip came a bit loose I took it off, rubbed the bar with sandpaper to clean & key it, wiped it down with methylated spirits, and then glued it back on with this:

That was about 2 1/2 years ago. Been fine ever since.  :028:

Just a bit off the subject , I have factory fitted grips which I find a bit small , are grip puppies ok for these pls ?
Title: Re: Heated grips not staying stuck
Post by: Shed on 23 March, 2020, 11:39:58 AM
For sure, you don't use glue to put puppies on.  :008: :110: :005:

With the puppies, I'd suggest just putting them in hot water first to make them a bit more pliable, then you should get them on ok. Some people use soap to help them on, but if you use too much then you run the risk of the puppies moving on top of the original grip due to soapy residue. So try without soap first.  :028:

And finally, measure twice, cut once!!

In the past I've used RTV sealant to put grips on, same stuff I use to seal exhaust systems. It goes on wet lubricating the grip so its easy to get them on and  once dried it and sticks like ..., if you ever want the grips off you may need to cut them. As above giving the mating surfaces a light abrade with EMERY PAPER to get a good key can only help .

Using an impact driver to remove a bar end screw is a little over kill. If you have a straight through screwdriver you can just give it a tap with a hammer, holding the screwdriver the wrong way round to get a good rotational purchase then tap and turn and that's exactly what an impact driver does. I'd guess the issue your having is someone has used a thread lock when installing the bar end bolts.

It might also help if you had the right screwdriver for the job. Here in the UK we have two types cross point screwdrivers - Phillips and Pozidrive the difference is in the angle of the cam or cross point. Now in Japan they have a third, they have JIT (Japanese  Industrial Standard) screws and screwdrivers. You can probably make do with a Phillips or a Pozidrive and many do the thing with using a JIT screwdriver is that the risk of camming out and destroying the screw head is greatly reduced.

Toolstation also have a cheap impact driver while you're in there getting the glue.
It's nowt flash & el-cheapo, but it'll easy be good enough for bar weight screws. Not the kind of tool you'll use very often anyway.

https://www.toolstation.com/impact-driver-bit-set/p90581

Or, just nip by any garage and ask a mechanic to give your bar ends a whack to free the screws if you don't want to buy an impact driver. I doubt they'd charge you for that. And if they would, just go and buy your own driver instead.  While you're there scrounge a bit sandpaper, emery cloth, broken file, stanley knife blades, etc, or good old-fashioned house brick to get the old glue off the bars and key up ready for your glue.  :028:

Because it is a JIS cross-point head not a Philips (incorrect drivers will cam out).  #2 IIRC (but the steps are small and #1 might do). 
You need the correct driver/s.  When I wanted mine years ago I had to import them from Japan but I'm sure nowadays they are more accessible.  If anyone sees them on a 1/4" (hex) drive though do give me shout as my 00-2 are all on handles complete.

I've got this set here:

Great little set, also perfect fit for the screws on the brake & clutch fluid reservoir caps, which you often see chewed to hell from previous abuse.
Bargain at £12  :028:

Iím getting an impact driver and super glue, but what bit specifically fits the job , (jm2 , you may need to tone  down the tech, just a type of bit and a size🥺🥺)I read all your threads with enthusiasm, but most of you talk a different language to me ( banter not criticism)
Title: Re: Heated grips not staying stuck
Post by: Shed on 24 March, 2020, 09:03:50 PM
Jon, both of the phillips bits in that Toolstation impact driver set will fit, (I've just been outside and tested this to double check). No, they don't fit 'perfectly' but you're just breaking them free, and these bits fit in easily well enough to do that. The bar end screws are large slots and easily take the impact drivers bits, or the #3 bit in the JIS set on the Amazon listing. Phillips & JIS are technically different sizes, but leaving the pedantry aside, a decent large phillips screwdriver that fits 'well' in the slots will do and will get the job done. Both of the bits in the Toolstation cheapo set fit well enough to undo the screws.

Note the JIS set is not an impact set and the bits are quite slender, so if the bar end screws are well stuck and it's some proper leverage you need you may well be better off just using the impact driver (or large phillips screwdriver) to set the screws free.

However, at the moment Toolstation is now closed due to Corona virus, so either get one off ebay, or the JIS set off Amazon.

Or treat yourself to both. Your choice.  :028:

Thanks Sheíd, I understand every word😂. Iíll wait and get an impact screwdriver, as Iíve got a Philips that fits perfectly, but I had no chance of moving it, thanks again Jon w

I too use RTV to install grips, but just a thin stripe, makes removing possible later.  To install or remove grips, an air nozzle inserted between the bar and the grip... slightly inflates the grip like a balloon, much better.... 
As for JIS, this is really what you need, but in a pinch you can fake it with a Phillips by grinding a millimeter off the tip to let it go into the head deeper.....
Small JIS bits available from Vessel, ebay, etc.,  or this Canadian guy.. https://www.gofastinnovations.com/

Post by: Art on 25 March, 2020, 01:35:27 PM
JIS vs Phillips screws/screwdrivers the difference is minimal and as above if you grind the point off the end of a Phillips screwdriver the difference is even less, but difference there is. Look carefully at the crosspoints, most noticeable looking at the screw head but can be seen on the screwdriver point too. The JIS screw crosspoints have squarer cut corners, the Phillips screw crosspoints have radius cut corners. It is this radius on Phillips screwdriver that can cause it to cam out when used on JIS screws, especially if some force is required.

Just checked and my CBF has PHILLIPS screws securing the bar ends, although I did notice the brake and clutch reservoir caps were secured with JIS screws.

I'll go sit on the naughty step  :003:

No need; but I would like to highlight it is more than the centre point, there is a angle difference too.

I still found my JIS a better fit than any of the other crosshead bits (tried at the time) for the my end weights.

How has a question on how to fix the grip turned into a 3 page thread?  :008:  :008:

The OP's question was about fixing the grip onto the bar, and the thread has turned into a JIS fest!  :087:

I contacted Oxford for a comment, and they said Iíd the bars had been cleaned properly and the right amount of superglue had been used I wouldnít have had a problem, slimming definitely getting an impact driver and doing it myself, the other reason Iím not taking it back to the garage is that the tank sustained scratches, which made me cross as the bike was in such lovely condition,I just wanted to thank everyone for being so helpful to a biking/ mechanic novice👍👍
