Hi all, just had a couple of hours on the old girl. Runs sweet as, but I noticed the chain was very slack after an hours ride, brought her back, undid the hub bolt, and it’s got to like cog adjusters on either side, I’ve turned them both the same and it’s tightened with a little slack, but not sure if the correct tension. I can get my thumb on the top of chain under inbetween the top guide, and thumb under the chain on the swing arm. I’ve tried to look but nothing video wise I can see to check. Thanks for any help.. kris

Evening all Hope your all keeping well . Bit of an issue with the above mentioned bike . Just did a top end rebuild on this bike bike , all went well or so I thought . It ran fine the first time I kicked it over . Tried again today and while it did run it stopped and seem like a heap of pressure was built up in kickstart. Whipped the plug out and noticed there was coolant there , not much I might add. Took the head off and the two o-rings were damaged. Also noticed that at the spot where the o-rings were damaged , the respective screws in the barrel were loose. Before I start ripping and tearing at it any more if there anything I might have missed t…

Got a leak in my master cylinder hose, so I took it apart to replace the hose and found this fairly soft black rubber item inside the master cylinder. It did was not attached to the lid so when I removed the lid it remained in the master cylinder. There doesn’t seem to be any hole in it so I’m pretty sure that the fluid goes into the master cylinder before this does. I can’t see any purpose for it, it just seems to reduce the volume of the cylinder! What’s it’s purpose and do I need it in there? Thanks

Hello. Has GasGas or anybody else released a seat for this bike? Does the 2022 version fit? Otherwise, have any of your folks devised a nice DIY version? Has anyone adapted a Long Ride kit from Sherco or Beta?

Hello , My regulator gives out approx 14.8 v dc for the fan circuit. When the fan runs the voltage drops to about 9.5 v. The engine sometimes cuts out when idling and the fan comes on, it is also very very difficult to start if the fan is on. I have tested the resistance of the stator yellow to ground and I have 8 ohms. I think I'm right saying the stator should not have any connection to ground, ?? Can someone tell me what resistance I should have and on which leads, I think it's yellow and green approx 16 ohms.. does that sound right. Thanks in advance Gary

Hello, I replaced the cover 3 months ago and it is cracked again, I have read posts but am still confused why the cover cracks...... Only thing is engine can backfire sometimes when kick starting, could that do the damage?? Bart gear, bearings etc were all replaced also...., small washer fitted on kickstart shaft.... Thank you

Hi everyone, I bought some swingarm bushings, seals and a new axle bolt but the swingarm bushings are so far off fitting. The seals are tight and the axle bolt is correct and fits the seals and bushings but the bushings dont fit in the swingarm right. The actual swingarm appears to be 25mm diameter and 48mm depth (each side) The bushings are 22.5mm in diameter so rattle in the swingarm and only 15mm deep so two of them (as per parts diagrem) dont make up the 48mm (even with the few mm the seals take up). I thought maybe I had been sent the wrong parts so ordered another set from elsewhere with the exact same problem. Only other thought was if the …

Can I use synthetic Type ATF F oil on a 2003 200 txt. Read some ware not to use synthetic on these.

Hi, I'm not sure if anyone can help with this, but any suggestions would be well received. I am looking for a new/good used seat for my 2001 TXT. After trawling through forums and calling dealers, I'm told they are no longer available (in any colour) and I am struggling to resolve the problem. Any ideas for a strong repair would be welcome, unless you know where there is one, preferably in the UK. I've done the zip tie trick to stop the mudguard flapping about, but it's not ideal. If anyone has used an alloy plate to bridge the two parts, how did it hold up? Thanks in advance 🤞

Hello, I recently picked up a used 2019 GasGas 125 for my son and I can tell someone has been into the carb. Can someone please tell me what the stock jetting is for a newer 125 with a Keihin at sea level and what jetting they typically use? Thanks!

Hi everyone, I've bought a cheap trials bike for getting into trials and also wanted to learn a bit about getting on the spanners as I've never really dare touch stuff on my enduro bike beyond very basic maintenance. I was hoping stuff would be easier to fix compared to my modern enduro bike (way too many electrics and parts for me to understand lol). Anyway, I bought a GasGas 300 TXT 2005. However now I have it home it looks like a mixture of bikes (doh - i'll probably do more research next time). To be fair I don't think the seller really knew either. It appears to have a Raga frame (I've checked the Vin which confirms this) and engine casings but the rea…

Hi everyone, Recently bought an old TXT some people have helped me identify in another post. I've fully stripped it now and pulled the cases apart. Mega help from someone on youtube who stitched all the Jim Snell videos into one 2 hour information goldmine. The only thing left I'm struggling with is removing the crankshaft. I've pulled the cases and removed everything else. It looks like its a special tool but I can't find mention of it anywhere online. Photo attached but I'm assuming the innter gear is threaded and needs some kind of splined tool to sit in the two inserts on the gear. Is that right? Anyone else done it before and have an idea or link to a …

Well, after detecting a piece of metal on the magnet of my 2020 txt 300 gp, I opened the motorcycle and the result is a broken primary shaft sprocket. The half-moon needle bearings were beginning to break and have produced some very slight marks on the inside of another pinion and the primary shaft itself. The truth is that it seems like garbage design and bad materials. My question is, will changing just the bearings be enough or since there are brands, should I replace the primary shaft and the two pinions?

KTM are now in self administration in Europe, they hope to get new funding and the news suggests all will be revealed by end Feb. https://newatlas.com/motorcycles/ktm-enters-restructuring/ I wonder if the other brands are in bother? They have a joint venture with CF Moto as well. My local Triumph dealers have just taken over the next door unit and are selling Pierer from these premises. (https://www.destinationmotorcycles.co.uk/) I have been drooling over the Augusta for some time and bought some Gasgas merchandise - its a nice outlet and the new bikes look really nice as well. Shame to see it all go bang.

hi Guys , looking for some opinions form riders who have tried out the newer generation of Gas Gas txt's 2024 onwards. currently ride a '21 txt 280 and i absolutely love it. i've had brief test rides on mates bikes, new shercos, Betas and Vertigos, and if i'm honest, i couldn't wait to give them back and get back on the 280. how much different are the newer models to ride compared to my '21 280? i'm yet to try one out. no plans on an immediate bike change, but would like to get some gas gas riders opinions. cheers !

At the very beginning I would like to apologize for my English. In my motorcycle, I have a problem with changing from 4th to 5th gear and from 5th gear to 4th gear, if I overgas it, the gear shifts. I've been driving like this for 2 years but now I decided to fix it. Can anyone tell me what could have been damaged?

Hi, Does anybody know if workshop manuals are available for the current GasGas TXT models (2019~)?

Hello , my 09 pro is a pig to start when the fan is on. The previous owner fitted an inline stat, this stat switches on and off at 68c , 67c, so it's hysteresis is very low. I have a stat in the top of the radiator also, it switches on at 69c and off at 55c. Which stat would be better to use? Is 55 , 69 a correct running temp? Thank you Gary

Help me set up the carburetor dellorto phbl 26 bs 1994. Motorcycle Gas Gas 1994, 237cc engine. The old carburetor parameters that were originally when I bought the motorcycle. 35 Pilot Jet 108 Main Jet D36 Needle 50 Slide 60 Choke Jet 350 Float Needle valve At these settings the carburetor is probably leaking. He just doesn't eat. Then I bought a 200 valve from Float Needle and bought a Main Jet in all sizes. I started trying to change the settings, I just changed the Float Needle valve to 200 and Main Jet 122, but it didn’t do anything. It still pours. Could it be a problem with the floats? Their weight is 2.8 grams. Maybe…

Hi all! My Gas Gas JTR clutch is not working. Unfortunately my package is slipping, I measured exactly 27 mm. 0.3 less than expected, maybe that’s why it won’t work? If you give it gas, the revs increase and there is vibration, but the motorcycle doesn’t move. It only works in 3-4-5-6 gears and maybe the springs have sagged, can you tell me what size they should be?
