Hi All, So I bought my used 2009 HRC with Oxford heated grips. Yesterday, leaving work, the throttle just felt stiff and weird. Changing up a few gears, while the clutch was pulled in for the shift, the bike was revving up. Then braking I had to physically turn my throttle OFF. Stopped for petrol 1 minute later, had a play with it, and the throttle is sticking OPEN, at any angle. Also very stiff to blip it. I realise the only difference between that morning and that afternoon was my heated grips being on in the morning. So I turned them on again, and the sticking throttle went away. However, it was the same this morning... I now have to warm up my grips as well as my enging before I can ride the bike. I do not know why it is sticking... I assume it is because of the cold weather. But my thoughts are - Is it sticking because it is cold or because something has melted because they were on? What if my grips stop working, would that mean I have a sticky throttle? I saw a mechanic friend on my way home and he asked if they used glue but I do not know the answer to that, and it is not glued in one place... It works apart from when very cold, so far it seems... I ride the bike all the time and really like the heated grips but they are not worth it if I cannot control the throttle because of it!!! Anyways, any advice on things to check is appreciated - should I squeeze in a bit of compressed air from a can that I have home to try to loosen it up or something?? And most importantly, be careful if you have these on yourselves... A bit tricky having to turn the throttle OFF!!!! Never had to do that before!!!
When I fitted Oxford grips to my Ducati I was hoping to not have to use the glue that comes with them to fit them but they were dangerously loose without them so I had to. Once done I found that the inside edge flange of the right hand side one was binding against the switch gear casing and causing it to stick. I loosened the casing and nudged it inboard a gnat's and the problem went away. I never had a sticking problem again heating or not.
Thanks Ken, I'll give that a go... Seeing as the grip itself ain't moving anywhere, moving the switch gear a bit sounds like a great plan!!
I have them on my Hornet, no probs so far. Used glue. Left a good gap between switchgear and throttle. Fitted bar end to suit Renthals.
Just had a look and there is definitely a gap between the inside of the grip and the switch gear... So it seems that that may not be the main cause but I will still have a go at movin the switch gear casing a millimetre or two...
This guy had the reverse issue to you Matrixxx. Turned out to be the throttle tube Sticking throttle when warm with heated grips - Bike Chat Forums Based on JM1's comment, this one's interesting too. http://www.xrv.org.uk/forums/transalp/77863-throttle-not-returning-after-fitting-heated-grips.html
What exactly?? Just check that the bar end is not sticking the throttle? I have R&G bar ends to install so will do so tonight as well as move the switch gear... Ok I read the links from Ken... Not sure I can move my grip as I believe they are glued on... Will let you know how I get on... Thanks for all inputs...
Agree. I don't have Oxford, but HG's on my 929. Had a very similar issue, was the bar end. Had to modify the grip (filed the bar end opening) to make it wider. Easiest way to check to to take the bar end off.
Oxford Heated Sports Grips I got several Oxford Heated Sport Grips on different bikes as well and I never had a problem. The only thing was, that I had to cut the rubber on the bar end, that's it.
See, I have original bar ends on right now, and on the right side grip, where your grip has 2 bits of rubber edgeing, mine only has one as they have already cut off where there is a groove between the grip end raised rubber bits... My connection to the grip is below the grip, not above as yours is... I will go take a piccy now... Will still try to remove bar end, move switch gear, etc etc... OK here are some pics... Middle picture I tried to show that there actually IS a gap there but yes it is less than 1 mm...
Mine wouldn't fit underneath the bar as the cable pointed backwards and I couldn't get a good enough radius on the bend to feed it out of sight. It had to be on top so the cable faced forward and could be tucked in behind the fairing.
Ken, when you said earlier that you moved the switch gear a gnat's... Did you mean the starter button/kill switch assembly? Or the one with the throttle cables? Isn't the one with the throttle cables always going to be the same distance from the throttle grip because of the tube inside the grip, and therefore immovable?? Please correct me if I am wrong, I've never loosened any of those... Please clarify for me...
Zoom in and see the difference. Compare you housing and 1mm distance with my Accassato housing and distance. I guess that's the problem on your bike.
The starter/ kill switch unit mate. Once I'd eased that away everything relaxed a bit and it was all free. Remember it was a mid 90's Ducati, so tolerances are likely to be a bit more....tolerant. It may well be that the new grips were longer than the originals and fitting them nipped it all up tight, but like Dev's my wiring definitely came out on top. I remember distinctly as I would have preferred to have them like yours, out of sight, but everything was far too tight and it kept fouling.
If after all that you are still struggling this may be worth a go It's completely different but i had a simular problem with my quad when wet, damp or cold it turned out to be just a dodgy throttle cable, replacing it solved all issues
