So, turns out the pilot jet was completely blocked! Problem solved.

Yes, got them from there and delivered already. Didn't solve my issues though!

Found a guide online and sounds like this "Death barble" is my issue. Seems like obtaining the o rings from anywhere in the UK is impossible though.

Ok. Will try that. Thanks.is there a guide online anywhere?

Ok so I still have this issue even though I've had the carb off and cleaned it out (it was perfectly clean though) and temperatures are back to normal (was around 18c today). Spark plug also looks ok and I've put a fresh air filter in. Again, screwing air screw right in helps a bit but if you leave it idling it starts to hunt and tries to die. If I give it a rev it then sits ok for a while. However, it also seems to be smokey, especially when cold. Any ideas what the issue could be? As I say, in the 6 years I've owned the bike the carburation has always been spot on and the carb is clean so it's not that. Was wondering if the fuel could be a problem but that's unlikely. Anything else that could cause this? Cheers

I've already cleaned the float bowl out and only use 99 RON fuel with zero ethanol. Carb hasn't been completely off and cleaned out though so might start with that and see how I get on. Will get a can of compressed air and make sure I blow everything through too. It's just odd as I've literally never touched the mixture screw or needles/jets and it's been spot on until the last 2 trials, both of which were circa 30c which is obviously a lot hotter than normal.

Prior to the 30c+ hot weather we've had recently my bike was running perfectly. Carburation was spot on. The last 2 trials have been in very hot weather and on tcikover the bike has started hunting a bit like it's running low on fuel. If I rev it then it's ok again for a few seconds then it starts picking and hunting again. The last trial I went to adjust the air mixture screw and found it was only half a turn out (I've not touched it in the 6 years I've had the bike, a 2014 300 Racing). Screwing it right the way in helped but not enough to completely eliminate the issue. What else can I do? Is there potentially a blockage somewhere? Do they do different air mixture screws? I don't particularly want to change needles or jets given that it runs great in 'normal' South East UK weather but if i have to switch to a hot weather setting then i will. Thanks.

Finished replacing the swing arm bushes and a new spindle. All greased up and no more creaking. The rivets for the chain guide were 5mm x 20mm with an extra large head, in case anyone else wants to know. Also, the parts diagram for my 2014 Racing showed a nylon washer that sits in the frame around the head of the swinging arm spindle. Mine didn't have one when I removed it so ordered a new one. When it arrived it didn't fit. Checked the parts diagram for a 2015 Racing and there's no longer a washer listed so I guess they amended the frame slightly to make the spindle a snug fit? Presume mine was a late 2014 and that was changed too. Odd.

While I have the swing arm out I thought I'd replace the chain guide (the one at the front that the swing arm axle goes through). Is that held in place by rivets? Does anyone know what size?

Yep, spotted that thanks. Bearing kit I've ordered comes with a new shaft so should be good.

Cool. Will give that a go. Have managed to loosen the nut and have ordered a new bush kit.

It's not the airbox as it was doing it even with that removed. So I checked the linkage bearings and re-greased everything just to be sure. Couldn't get the swinging arm bolt undone so will spray and leave with penetrating spray for a while and try again (once I get some). Put everything back having checked chain tensioner and anything else I could and there's still a creaking. I'm now 99% sure it's the swinging arm bearings as there's also very slight movement if I move it side to side. Doesn't make any noise when not connected to the shock but does under load. I have a feeling getting the swinging arm off is going to be a mission but it needs to be done. Fingers crossed once the nut frees up the rest will be simple. Are there any tools that I can get to help with bearing replacement?

Thanks for the replies. I'm going to remove th3 swinging arm and grease it up anyway, as well as the linkage. Maybe that will fix it. Will check chain tensioner too.

So my 2014 GasGas has developed a very annoying creaking noise which is very difficult to locate precisely. Even the slightest movement pushing down on the footrest makes it creak. It's definitely not a squeak and sounds more like dry plastic rubbing than anything else I've taken the rear shock out and the swinging arm moves up and down smoothly with no noise. Similarly the dog bones move freely with no noise. Thinking it could be the shock itself I've removed the spring but the piston shaft moves freely (with a firm push) with no noise (also had it refurbished about 2 years ago with little use since). What on earth could it be? Open to trying anything as its very loud and annoying. Thanks

For anyone that may be interested I fitted the adjustable ring and moved it to position 2. Clutch slip has completely gone and clutch is as light as it was originally.
