Just a quick question before I put my engine back together, I’m asking just to double check because I have a feeling that someone else has split the case before me, anyways I’m just wanting make sure the crank seals are in the proper way, is the proper way to have the spring inside the seal towards the crankshaft, there’s three seals all are internal with one on the clutch side and two on the mag side please correct me if I’m wrong thanks

Anyone know the stock spring weight for a Tech 39 with red caps (aluminum tubes). 2020 GasGas TXT 250. North America.

Just a heads up for anyone needing to modify their clutch pack. 9.75-9.85 is quoted so often i recently modded my 2018 clutch to around 9.80 then found this information the next day. which says that 9.8 would be beneath spec for the newest bikes. I didnt think the clutch changed so much over the years. Take what you want from it, but just a word of warning that the often quoted 9.8 may be going too far especially if you decide to sand down your fibres. Still don't know why they don't make 1.9, 1.8 1.7 mm thick plates

I've got a low hours on the existing OEM fiberglass type packing but in the quest to make it as quiet as possible I purchased some "Long strand/Loose fill" material to try out. It looks just like the Jitsie product if you are familiar with it. http://areapnolimits.com/products/Muffler-Packing.php Makes sense to me... This info was very helpful because the G-G core is wrapped with a mesh Pic of the original packing material and the mesh wrapped around the core removed it (but saved it JIC) The challenge here is that the modern end cap is very long unlike a typical mx/enduro silencer and the older GG's …

Hey, Does anyone have experience with a compression test? I understand there is no standard. It will be different per engine, but I am looking for an indication whether the piston/cylinder may be worn. I now measure 75PSI and according to an earlier topic that is too little. who can help give me some advice? The bike is an Gasgas TXT300. 🙂 Best regards.. Alex

the decal on the bike says "Unleaded 2%" ( which = 50:1 ) but the manual says use 98 octane at 67:1 (and a "Jaso FD" classification type) think there would be any issues running this VP fuel? I cannot obtain the called out Motorex fuel near me. TIA

Hello, Let me introduce myself briefly. My name is Alex and I am an Gasgas enthusiast from Holland. I've been in the middle of hot fires, but now I'm clueless. Herr’s my problem, I hoop you can help me? Gasgas TXT 300 from 2004 does not want to start What have I already done: Kick starter gear replaced. Replace ignition coil. Replace CDI unit. Replace the voltage regulator. Carburetor ultrasonically cleaned. New spark plug. New piston and cylinder replaced. Strangely, he sometimes starts in 1 or 2 kicks but after stopping he starts very difficult (10 to 15 stairs) most of the time he doesn't start a…

Hello, been creeping the forum for awhile now and was hoping you guys could help me work through an issue! 07 gas gas txt pro, bought this year, bike was like new with original tires, been having a blast using it to poach mountain biking and hiking trails. Brought it with me on a trip and had to do a creek crossing, it was a little deeper than expected and the bike died when I got to the other side, kicked it over for 30 min and finally went. Then I had to go back across, well soon as I hit the water same issue. This time I kicked the poor thing over for an hour and got it started, was running terrible , misfiring etc. Now it won’t start. Performed the follow…

I feel like I should have wrapped my head around this, but I'm struggling. I pulled the 2012 gasser 280 out this morning , before ride I noticed milk coloured oil. Impeller, seal and shaft have been done within the last 40hrs. I changed the oil, still milky and rode for maybe 15mins, noticed the fan not coming on. After the ride I jumped the fan to a spare battery, it works great, testing the thermostat, it seems to always have resistance and isn't opening, put it in boiling water, no click and no real changes in resistance. So... I would say bad thermostat, but could this overheat coolant into the oil? or do I have multiple issues? Or am I missing something! FYI it is ov…

dellorto phbg 21 ds gas gas 70 2003 Carburettor adjustment. Hi all I am trying to adjust the tickover on this carb/ bike . There are two adjustment screws on the side Idle mixture and slide stop screw . I have taken this carb apart and blew out and cleaned all visible jets and galleries. Now back on bike and starts and runs ok but the tickover screw doesn't seem to be able to screw in any more to raise the speed of engine. I have bought a new slider and this does not make any difference. Can anyone think of any other things I may be missing . Regards Neil

Hi looking for some advice please, I’ve got my girlfriend a gas gas jtr 125 and was wondering if there is any way to restrict it while she learns? thanks

Hi can anyone tell me where I can get a rebuild kit for the hebo front caliper from a 2003 txt 70. Also the dellorto carb spares as I think I need a slider that the needle fits into as the tickover screw seems to have worn away the bit of the slider it actually touches. Kind regards Neil

Does anyone know where I can buy o-ring for exhaust for cadet 80?

Hello everyone I have an issue that's puzzling me. I have a 2017 280 TXT Racing. I've noticed recently that after starting the bike, and letting it warm up for 3-5 mins (choke for only about 30 seconds of that) - when I first start out, the motor seems like it's loaded up. It's almost like it's missing - lack of power. After another 2 mins or so of riding, it evens out and runs like a champ the rest of the day, even after long stretches of sitting. I believe the bike is jetted correctly. I consistently run 100:1 Two changes I've made in the last few months: 1. Changed from Yamalube to Motul for my mix. Bike seems to like it, can't imagine this is it 2.…

My 1998 tx320 needs a new seal in the brembo rear master cylinder but this part seems to be obsolete, any ideas of how to replace this obsolete part short of buying a whole new master cylinder

Hi all. Anyone fitted the splat shop 15% uprated rear spring to a Sachs rear shock on a gasgas txt pro 2012 250cc? It appears to be 15mm shorter than the original and to have it held in place it needs the preload to be all the way down to the end of the threads!! Any thoughts?

Hi there. We bought a 2021 Gas Gas 125 Racing on the 23rd March with the special deal of £1000 discount. There were several things that had to be sorted before it could be made ready to ride. The second time it was ridden by our 13 year Granddaughter it started mis-firing and back firing. The van we transport it in had a lot of condensation and the wires and CDI unit were damp. It had been put in the van over night after a few hours running the motor in. My son dried everything off and the motor was running well again. But after breaking down twice at trials and 17.8 hours of running it failed to re-start after a few hours of riding and had t…

Hi, first post here. I have a 2007 gasgas txt 300 pro, I dont know if I have a leg like a donkey or if I'm really just a jackass. I have a knack for kicking the kick lever off of bikes, all bikes; I promise I try not to do this. So onto my question finally, what are the most durable kick levers I can find for this bike? I heard steel ones are frowned upon but the aluminum one that was on the bike bit the dust the second day I owned it. It may have been just fatigued but I'd rather just not ever question such a simple, yet integral, parts reliability again.

Hello all , first post here and its for some help....hopefully I can explain this correctly I bought my young daughter a gasgas txt50 boy and after doing some googling I am getting conflicting advice (from gasgas dealers and owners) For gear/clutch oil im being told 10/40 engine oil OR 75w gear oil.......the problem is ive tried both and getting different problems with both. heres whats happening Engine oil - bike sounds great , gear engage is great BUT the clutch slips really bad to the point it is unridable gear oil- the bike runs and the engine pulls really really well BUT in netural it will randomly jump into gear and lurch forward by …
