I tried to put the engine back together, but couldn't figure out why the kickstart wouldn't work as prescribed. The ridiculous return spring set-up is causing my headache. The spring seems to have lost tension in a spot that allows it to curl under the inner loop of the spring and sit there so that the shaft will not sit home. So frustrating. I have spent 2 hrs trying to solve what should be a 30 second job. Anyone want a GasGas.........

It is a worldwide epidemic b40rt. We don't seem to be able to thin them out with trams in Melbourne either.

What a brilliant idea! Well done to the people who put this together. Great work.

Couldn't read through 121 pages to see if this is here, so apologies if it is, but: Wife is standing in front of the mirror, She looks herself up and down and says to hubby, who is sitting on the bed reading the paper, "I'm old, fat and wrinkly. I need a compliment" Without lifting his eyes from the daily rag, Husband replies, "Your eyes are ****ing spot on"

I think a lot of people are missing the point a little. The FIM couldn't give a rats about selling trials bikes, or how many people take up the sport. The only thing that matters to FIM is that people are watching and they are getting advertising dollars. I am sure in some championships they are losing money but making it up in the others. To make the sport a bigger spectacle they want to bring the competition closer together. To keep manufacturers competing, they need to make it cheaper. I can understand how no-stop MAY bring the competition closer together, but I do think Bou will just adapt and continue to dominate. We will see if it works or not I guess. I don't like no-stop, and don't agree with it. I think the spectacle is in what these guys can do with their balance. Pushing the limits, bouncing on the back wheel, jumping sideways from obstacle to obstacle. Unbelievable.... As for weight limits, again I can't understand how it benefits. OK, maybe it could make bike development cheaper, but as others say I do believe it will force manufacturers to develop more expensive components. I think it only really advantages Honda, which is counteractive if they are trying to bring competition closer together. Just my thoughts on the matter. Interesting times ahead.

I pulled down my TXT250, and got ready to order the Kickstart gear and Idler gear, head, base and exhaust gaskets, oil filler plug, header pipe bolts and a piston kit. It has a 300 barrel on it with the high comp insert for the S3 head. Can't wait to actually ride it...........

Well done Dylan, great result, after an immense amount of effort, well deserved mate.

One of my friends is a Maico Fanatic and owns at least one model from every year they were made. I think the only year he is missing is 1976. I think he has 30 or so all up. Some of them are fully restored using all NOS parts and are as good as or better than showroom condition. It is an impressive collection, that's for sure. I will endeavor to get some photo's to add to this topic.

Oh and pull your pads out and push the pistons all the way back in too, this will "reset" the pistons and seals and get both pistons free and moving again.

Snobbly, Google is your friend mate. You need to ensure the system is bled properly before you do anything else. Try this one: I didn't watch it all but thought it may give you some guidance on what you need to do. Start there as brake fluid can absorb water over time and this will reduce your brake pedal feel too. Flushing and replacing your fluid is definitely step number one.

I had a next to useless back brake on my Scorpa, when I bought it. I have spent countless hours trying to get it sorted, until Saturday night when I finally did. I was getting zero pressure from the master cylinder because the push rod adjustment was up the ***** and there was air in the line. Because the piston was being pushed prematurely, it wasn't allowing it to return all the way, stopping the fluid from returning to the reservoir. I started by figuring there was air in the line. I tried bleeding and couldn't get anything to happen. I soon realised that the push rod was not returning far enough and had to remove the brake pedal to get correct adjustment. This was a task as the bolt was rounded out and way over tight. I ended up drilling the head of the bolt off, then punching the bolt through. I wrecked 5 drill bits on the hardened bolt!! Once I was able to reduce the adjustment on the push rod, I could then get enough pressure from the pedal to bleed the brakes properly. Once I had got a result from here I was able to set up the rear brake to my liking and sort out my woes. It took some time but at the end of the day all was well and good. Good luck with it mate, and make sure you have everything adjusted correctly in the pedal area before you start to bleed the system.

Well yet again Bou has come through and taken the title in emphatic style in the indoor championships. Can he be stopped? I think after 10 of each he may consider Extreme Enduro! Good on him I say, the guy is without doubt a level above the competition. I think we will see how good the Honda/Montesa is when Fujigas takes his leave. It'll be interesting to see who steps onto the ride, maybe Casales. Honda do like to snap up the younger talent early to ensure they maintain that no.1 plate. Wish I could get coverage of the full event to watch. We get zero coverage in Australia, which means I can only watch the 20min final that the FIM put on YouTube, which won't be there for a week no doubt. Anyone here record it on a media they can copy it from?

I'll check it out, thanks Dabster.

Thanks guys. I will measure up the barrel after giving it a good hone and make sure the clearances will be ok with the new piston, check my ring gap etc. If all measures up ok I will not bother re-coating the barrel. A Wossner piston will cost me around $140 in 79.98mm. I need to price up gaskets etc, but they should be around the same money I would think. The kickstart gear may be a little expensive, but after that it'll be happy riding days all over again.

So the other day I bought a bike that was sold to me as a 2009 TXT Pro 300. The bike had a hard life, I could see that when I looked at it, and I am a mechanic, but on initial inspection and with a brief ride all appeared ok. Geez, was I wrong. Firstly, when I test rode, for a few minutes only, the motor seemed quiet and ok. I got the bike home and rode it the next day for 20 minutes or so and as it got hotter it got noisier. A real tappy, clicky type noise. Something I had not heard in my limited time with 2T's. I googled my ass off and found that they are a fairly noisy motor. Still I am pretty sure at that point that this wasn't the normal Gasser noises. The night I brought it home I also thought I would check out the chassis number and it appears that it is actually a 250 that has had a 300 barrel put on it. So after being sold a TXT Pro 300, I had actually bought a 250. Kicking myself for not researching the chassis number beforehand. I rode it some more and the gearbox oil came up very milky looking. Next problem............ I am not happy at this stage and am thinking the worst about the bike. He had said he had just done the water pump, but it seemed a little too much milk for it to be residual water in the gearbox. I am getting more and more annoyed at myself for being a bit hasty on the purchase and was wishing there was concourse for return. Unfortunately though, there isn't. I drained the oil, which came out not too milky in the end, and seems to show less water problems than originally thought. Some silver lining starting to appear. Then I remove the oil filler plug and it is cross threaded like a *******. What a butcher that I bought this off. I remove the water pump and it all looks good, no water in the back of it, so that at least confirms residual water in the gearbox causing initial milkyness. I have since removed the top end and it needs a piston and rings, as the rings were stuck fast in the piston. Maybe a cause of the noise I was hearing. Also the exhaust header was loose, another possible cause of the sound I heard, and this being the most likely cause, as the sound wasn't consistent or uniform like you would expect from a bearing sound. I have put it down to these two things. The bore is in ok condition, but will need a hone. A piston measurement confirms it is 300cc. So it would seem it is a 250 that has had a 300 barrel put on it. The big end bearing is tight and shows no signs of any wear. This is also a positive. The Kickstart gear is missing 2 teeth and the others are grinding away, which explains the metal shavings on the magnetic filler plug. The carby needs a clean as it is leaking when the fuel is left on. So that is the tale of my woes and bad start as a Gas Gas owner. I think things aren't as bad as I first thought, but there is still a few dollars to spend to bring it to a rideable state. I hope it holds up as a great ride once I have finished working on it. Thanks for listening.........

There is definitely something wrong. I haven't personally worked on a set of 315r forks, but I imagine they are like most cartridge forks. They should be the same length. I would check that something hasn't been assembled wrong in the compression circuit.

Agreed. The other issue is the chain at revs may fly forward and put a hole in your engine case, which is generally unrepairable. A very expensive repair will ensue. Do the chain and rear sprocket too mate.

Yep 22kg. That was the 2010 motor that had the old head on it. Pretty sure they didn't gain any weight when they went to the V-Head, if so it would be marginal I would suggest. The motor is awesome though. Very reliable too. Really miss that motor in my beloved Husky's!!

This is true of the style of rims that require the rim tape type seal, but a lot of the newer bikes are now running the wheels that the spokes do not penetrate the rim. This all but guarantees no leaks. A puncture is of course still possible, however would allow for a tubeless plug type repair (under the right puncture type of course). My Scorpa has the rim tape type seal, I was having heaps of issues trying to seal it. I solved the problem with sikoflex! Every spoke sealed, a bead of sealant either side under the rim tape seal and then a bead of sealant over the top of the seal. Perfect!

You just have to keep trying, you will learn how to get traction in poor conditions the more you do it. Still makes it hard though! Looks like you had fun either way.

I would probably replace the spark plug anyway at this stage. If it hasn't been done and the bike has flooded a couple of times you may find it has weak spark and that is causing your difficulty to start. Also, rather than just kicking at the starter, try to time it a little better. Kick it over slowly until it reaches top dead centre (when the kick gets it's hardest to push), then resting on the kicker, give one big effort with a little tiny bit of throttle. If you can get the timing right it will start basically every time, as long as mechanically everything is fine.

Working in a Husky dealership, the engine they have purchased will prove to be a brilliant decision by them. The X-lite motor is a brilliant little bit of kit, capable of very impressive torque and power out of a 22kg unit. It is by far and away the lightest small bore motor around at the moment and deserves to remain in manufacture. Hopefully seeing this in a trials bike will be a great move for GasGas. 4 Stroke is the future, there is no doubt of it. I love 2 Stroke motors, especially trials motors, but I think eventually they will fall by the wayside. As far as ceramic goes, all great in theory, but reliability will be an issue. Just look at the ceramic washers that were used by Sea-Doo in their supercharged jet ski's. Every one of them failed long before the motor did and disintegrated and went through the motor, leaving a true mess in it's wake. I don't think ceramic technology is quite there yet.

So this is a 7 minute video of my second outing on the trials bike after 20 years off. It was a good night where I ended up surprising myself a fair bit. I ended the night with a crash off an obstacle which I probably shouldn't have tried yet. The bike ended up with a stuck throttle and revving at full noise for 30 or so seconds until we managed to stop it. I didn't get this on my helmet cam though unfortunately! The guy in the orange that you see a couple of times is Dylan Rees, who is one of Australia's top trials riders, and someone I rode around with as a kid. Luckily I managed to catch him crashing on a simple obstacle, which is always entertaining!

I went down last week and managed to have a cracker crash, which I didn't get on tape. Still to check for any damage to the bike. I will post some of my efforts though once it has uploaded to YouTube. I don't think I will make there this week however, but I do look forward to your next installment!

This is the exact reason I purchased the Scorpa. After 2 outings I am already scouting for a more modern bike now, and don't think for one second that I will loose on the Scorpa. You can't go wrong really.
