Gas Gas

I’ve bought this bike a few months ago. Very pleased with it so far, but it’s obviously not been very well maintained, which is fine as I didn’t pay much and suspected that was the case anyway. My questions relate to the exhaust system. Firstly, it clearly has much black coke inside and every time I ride the bike for any more than about 15-20 mins I get a trickle of black oil running out of the lowest joint. I’m running an oil ratio of 60:1 - is this too much oil, hence the black trickle? Secondly, is this silencer designed to be repacked, and if so do I need to drill out the end cap rivets to get to the inside? Many Thanks

Hi! I'm new to the sport and recently bought a GG txt pro. I would like to connect the speedometer but can't find any connections under the tank. I might be a bit stupid but it seems that some cables are missing. Regards Henrik from Sweden

I have a 2023 GG 300TXT. The manual says spoke torque is 26 inch pounds for rear and 18 inch pounds for front. Most dirt bikes and other bikes I have owned are spec'd between 40 and 50 inch pounds I checked the spokes yesterday on my GG and they are much tighter then what the book called for. Am I misunderstanding something? Any and all thoughts are appreciated.

Hi I’m looking for the correct flywheel puller for my 250 & 327. I’ve been told it’s a M30x1.5 but this is far too big. Also I know there are at least two types of the Motoplat electrics. Mine has a module adjacent to the Cdi with 3pin and 2 pin connectors on it and I know there is another larger module with wiring coming out from it with floating connections. Which is the later? Attached are the Flywheel and module photos. Both my bikes are 1989. What are the Timing settings for both bikes please. Thanks in advance.

The above Ducati ignition fitted to the 04-07 250 and other capacity bikes is obsolete… anyone replaced theirs fairly recently and have any recommendations on what to do / which parts? I have seen so far… Trials Bike Breakers UK have a full Hidira kit (inc flywheel) Hell Team (Oz) have CDI and Rectifier plus full kit options Full kit on a couple of other websites I am going to keep looking for other options… nothing on Ali Express… confirmed obsolete by John Shirt Motorcycles (Gas Gas UK). Replacement costs seem to be either an arm/leg for the rectifier and CDI, or an arm and a leg for the full kit… full kit really not in the budget fo…

Hi does anyone know of the correct jets and slide pin for the txt 70 cc Regards Neil

Can't figure out what year my TXT300 is. I've read many of these and it says the 10th digit which is M.... no idea what M is though. Any help is appreciated. I'd like to sell it. Thoughts on price? Runs great. VTRTG 3003 M120 6138

I have a 1995 JTX 250 and am having a few issues with the clutch I have removed clutch assembly and cleaned all parts also have checked and both pushrods and bell bearing in between are present I have bled clutch out I have adjusted leaver but still the clutch does not fully engage or disengage I have noticed the small ball bearing in the space cylinder has been pushed back into the cylinder so my question is do i need to replace the cylinder and seals or can I do something else to make it work better ?? Please help if you can it is fully appreciated . thanks in advance

The short story - the threads for two cylinder head bolts are stripped in the cylinder barrel. The bitter story - DO NOT buy torque wrenches from Amazon. My question to this esteemed body - should I replace the cylinder or try helicoil or some such repair? If it is to replace, OEM or third-party?

There are incorrect descriptions both in the paper manual that came with the bike when new and also the PDF owner's manual for 2006 Gas Gas TXT Pro. I noticed this the first time i had a look at the manual. There might be more wrong stuff in the manual for what i know. Is it typical for Gas Gas to have incorrect info in the owners manual? Does other years of Gas Gas TXT have incorrect info as well? Have a look at the 3 pictures posted below. The pictures below is of page 20, 22 and 29 in the manual.

Hi guys m I’m hoping to get some opinions here for a problem I have with the bike. txt 280 2021, not done a lot of hours. I’ve got a real splutter/misfire coming off closed throttle to 1/4 throttle . I’ve stripped and rebuilt the carb, new o ring seals everything , but the problem is still there . so it’s pointing at the electrical side now I’m guessing . My cdi pins are pretty furred up, so I’ve cleaned them , but still no joy. can anyone else recommend where I look ? Is there a way to test if the cdi unit itself is the problem? I’m checking all my earths and connections now . any advice appreciated .

They sell complete new decal sets for trial bikes on eBay for a cheap price so i wonder if any here on the forum have put on these new decal sets? If you have put a new decal set on your bike so please tell us about the quality of the decal sets and please post a picture of your bike with new decals 😊 😊 The picture below of a decal set for a Gas Gas TXT Pro is from ebay, UK

On my Gas Gas TXT 125 Pro i have a 9 tooth front sprocket (if i counted it correct) and what i think is a 46 rear sprocket. If i go for a 11 tooth front sprocket and a 49 tooth rear sprocket will i notice any differnce? I must say that i have a feeling that i will not notice any special differnce if i replace the front 9 tooth and rear 46 tooth sprockets with 11 t and 49 t sprockets or am i wrong?

I have an 2005 Gas Gas TXT 125 Pro that i have been standing since 2017 without being started. I tried to start the bike today but it would not start. The first thing i did was to check the for spark (which is okay) After that i took off the airfilter box and rear fender. I found an old hand pump spray bottle which i poored gasoline with 3% oil mixture in thinking of spraying fuel in to the carburettor. I am aware that it is supposed to be 2% but since the bike have not been started for a long time i decided to use 3% oil mixture. So the first time i tried to start the bike i sprayed in 2 spray pumps with fuel from the the spray bottle. This wa…

I see there’s been quite a few advertised updates for the 23 and on models (not sure if there is any difference between 23, 24 and newly announced 25 apart from cosmetics). They look cracking. But can anyone report on whether the differences are enough to warrant upgrading from a ‘21 model? How different are they and do they start any easier? I’m talking the 250 model TXT Racing predominantly. Considering it as they look lush but wondering if they are worth an early upgrade. Sportsman/Clubman level rider so nothing adventurous. Interested to hear any reviews, good or bad.

Sorry for my first post to be this one guys but I'm at a dead end at the moment. Had my top end redone because of low compression, and since then I haven't been able to run the bike. As soon as it gets warmed up it just cuts out? I've changed the carb,CDI, spark plug checked the wiring ect searched multiple times for post on forums so thaught I'd ask myself. Any input would be greatful thanks guys

Hi Does anyone know if they do a flywheel weight for the 125 TXT ? I see lots listed for 250 and above but not sure on 125 ? Thanks in advance

Hi all, i have got a gas gas 321 2001 with rectifier/fan issues, i get ~10v ac from the voltage regulator, then at the rectifier when input the multimeter on the red and black wires to and from the fan (with the fan disconnected) i get ~25 to 30 volts, which is going to cook the fan pretty quick, when i earth the black wire i get ~ 10 to 12 volts, not sure what is happening there if anyone has had similar issues ? And could help please Thanks Anth

Hello, can anyone please help me with this? I have a GasGas TXT Pro 300, 2009 that I am trying to reassemble. I cannot figure out if the shift drum goes onto the shaft first or if I insert it first into the gearbox and then onto the shift shaft. Either way, it seems to be difficult to find the right orientation of the drum. Is there anything I am doing awfully wrong? Any hints would be greatly appreciated.

I bought a project witch I was told it was a gas gas Pampera 250 I am trying to find parts wich is near impossible and looking for some advice it’s all stripped needs a top end and new plastics, pads front and back and discs new clutch kit new wheels does anyone know where I can find parts for this or any advice about the bike as I haven’t really got a clue what it is I’ve heard it’s based of a trials bike but not sure
