  1. Thanks! That's what I figured out, green bladder so I went out and used 5W fork oil (couldn't find my Magura bottle from my KTM days). DC
  2. I need to bleed and probably flush my 2013 TXT Pro 250 clutch line (engagement has become inconsistent after I looped it, so I think air got in there). The previous owner replaced the clutch (and brake) master cylinder caps by nice S3 anodized ones, which doesn't help in telling me what's in there. Is there a way to make a difference by looking at the fluid? And what's the best way to bleed these things? Push fluid through the bottom with a syringe? Thanks. DC

    "Yamaha just released information about its all-new TY-E electric trials bike, which is a concept model. The TY-E is powered by a high rotation-type compact electric motor and is equipped with a mechanical clutch. The electric bike uses a high-output battery pack that is mounted in its carbon-fiber-reinforced plastic (CFRP) monocoque frame" (more here) Close enough in my book.

    EM uses Golden Motor motor and I think that the Gas Gas TXE will use a custom motor (designed by Toro and probably manufactured in China). Now... there is a possible new entrant in the Electric category race... No gearbox, but a mechanical hydro clutch. Carbon fiber frame!
  5. Tech fork on 2013 GG

    Yep, 98204Y will work tho (20x42x9). This is getting way too complicated tho... (and expensive!)
  6. Tech fork on 2013 GG

    Thanks! Here is what I understand: Wheel bearing The Tech Fork has a 20mm axle vs the 25mm on the Gas Gas. So I need to drop in some 6004 bearings in the Gas Gas wheel. Bearing spacer I need a new bearing spacer with an OD / ID that will match the 6004 bearings Wheel Axle I'll need a Tech Axle Fork clamps I'll need adapters to go 40mm to 39mm for the top and bottom clamp (4 of them - I think I saw these somewhere online...) Wheel spacer Not sure if I'll need any spacer to set the wheel centered in for fork and to align the brake disc with the brake caliper. Anything I am missing? Thanks!
  7. Tech fork on 2013 GG

    My zooch is getting pretty beat up (bent sliders, several nicks in the sliders, starting to leak oil...). So I can either keep fixing it (which range to fill in the nicks in the sliders with the usual mail polish trick and replace the oil seals to getting new sliders), but I found a tech fork for a reasonable price. So I am wondering what would it take to put that tech on my GG. Here is my list of questions: Tech is 39mm, Zoock is 40mm, but I know there are adapters Front brake (tech are usually using the braketech setup, mine has the older AJP (?) Will that fit in? Wheel axle - Will the stock GG axle fit? Wheel spacers (that I can probably get made or buy) Am I missing anything? Thanks.
  8. Yeah... Got myself a new bash plate! Then I'll beat the old one into submission as a spare ;-) I have all new rubbers too.
  9. Well, it's a trials steel frame without a lower cradle so it really isn't the stiffest thing around especially at the front (you can bend the thing by hand if you are not careful!). So my welder just makes sure that the crack in the mount is closed (tap it into place with a hammer) and weld it back together. Then the mounting sequence is: drop the engine in the frame, put the swingarm spindle in, put the lower rear engine bolt in, then the front engine mount bolt then the top bracket and slowly tightened everything in the same order a little bit at a time. The challenge will be the bash plate. If it's new (i.e. unmolested) it should drop pretty easy. If it's been bashed (flatened) , then mounting it can range from being a challenge to impossible. In the end my frame could be twisted a bit, but since trials is about riding on crappy terrain with under inflated tires... it doesn't make much difference to me :-) Hope this helps.
  10. Thanks! The kickstart side seems pretty straightforward. One the sprocket side, that looks a little more complicated... If I get it right, on the sprocket shaft there is (starting from the inside of the engine): A 25 x 2.0 o-ring - ME25632025 (#25 on the 1st exploded view below) a 25 x 1.5 o-ring - MT280212025 (#29 on the 1st exploded view below) A bushing - MT280236046 (#24 on the 1st exploded view below). An oil lip seal - ME25636024 (#37 on second exploded view) And to get to all of this, it means removing the left side engine case, which requires removing the ignition cover and the ignition... Anything else? So now that I have the engine out of the frame, that might be a good time to do this service I guess!

    PMed you
  12. One of the rear engine mount on my 2013 Gas Gas TXT broke, so the frame is off to the welder to get fixed (bash plate flattened from too much bashing, which spreads out the frame, which in turn puts pressure no the engine mounts and I'd rather have the engine mount break than the engine cases crack!) Now... I could bash on things less, but then I'd have to become a better rider first! So it's a good opportunity to finally do winter maintenance on the bike (which I keep pushing off because of the just incredible weather we've been having here in California). I have a long list of things to do and it includes changing the seals around the kick starter shaft and gear shaft, both of which are seeping oil. Can I do that without taking the engine apart? Thanks.

    Here is the Torrot version of the GG TXE (Torrot bought - rescued? - Gas Gas and they make electric bicycles and scooters. https://torrot.com/en/preordermovak

    Yeah, altho work isn't as much the problem as the $'s. I need to take the engine out because I have a cracked engine mount at the back (and it's cheaper than buying a new bike) so once the engine is out, changing the jug / piston isn't that big of a job (especially on a 2 stroke!).

    The guys at Gas Gas US told me that they expected two different electric trials bike: one with the clutch gearbox (around $12k) and one direct drive (a la Electric Motion). I suspect the direct drive version will be cheaper and positioned to compete against the EM, Mecatecno, etc. Looks like the EM's are popular in France (Europe?) in trials school at the beginner level. No clutch to worry about for the rider, no gas, low maintenance for the school. So my guess (if the information I have is correct) Gas Gas will market the direct drive alongside the Contact and the geared one as a competition model.
