    My fiber plates look just like ADVCoop's that he posted, only two of them still had the fiber material still attached to the plate, the rest all had separated similar to his his, and a two inch section of fiber from the outer most plate was missing :huh

    The pressure plate had a raised line on the outside perimeter that alligned with the bolt hole on the housing with the little depression on each side of it, so it appears there are markings to insure I get it back in the same position.

    The throwout bearing or whatever you call it on these things looks to be in fine shape, should it get replaced or can it can be left alone? Seeing I am super broke I am hoping the steel plates check out to be perfectly flat and I only need to get replacement fiber plates. The more I have to get will only delay me getting it back running, and I would like to be riding it sooner rather than later if you know what I mean :D

    Sorry to read. Check the Tryals Shop for a clutch. At least for mine a new complete clutch is only $139 from there. I've heard stories of $300 clutches so I was worried.

    Here is a picture of the raised line I was referring to on the pressure plate. It is above the top bolt hole in the pic.

    And the hole that matches up with that one has two small depressions on it whereas the others do not as you can see below.

    And the fiber plate I thought had two inches missing did not have anything missing, it had just had two pieces slide under the adjacent piece making it twice as thick on a part of it, hence the excessive dragging.. I have a picture from the side of that plate below.

    Notice the two areas where there is a step so to speak.

    That would be awesome if I could get the replacement plates for $139.00. I am making a list using my parts book and I am going to call the the guy at the trials shop tomorrow to see what the prices are for the things I need.

    The clutch pack for mine is also $139.00, so that was good news. :clap

    Fork seals are 20 for a pair.

    The wrung off bleed screw on the clutch slave is a non issue as Mike advised me just to bleed it with the cover off as the bubbles will all rise to the reservoir anyway.

    Hope to get the seals and clutch ordered this week, now just to find out torque specs on the clutch springs and head.

    Found the video for the clutch work which describes a lot of things, except the torque specs to use when reasembling the clutch basket or the clutch cover :baldy

    Apparently synthetic oils are known to cause the issue ADVCoop and I had with the fiber material seperating from the disk, so I will make a point to grab some non synthetic 5w/30 next time I am in town.

    I saw that video and put 5w-30 in it right away when I got the bike. I changed it a couple times thinking maybe the last owner used synthetic and that's what caused the drag. When that made no difference, I checked the plates. I'm glad I did. My clutch should be here tomorrow.

    The spring bolts are just barely tightened past snug. The spring tension will hold them in place. Many people overtighten just to have to buy a new clutch basket. Same with the outside cover.
    PS. GasGas USA recomended mobile one for years. So I would not sweat the oil too much.

    He shipped my clutch on Tuesday and I had it Thursday, just for reference.

    Got it today actually, I am impressed with the USPS priority mail boxe, ordered it Friday midday, paid 8 dollars shipping and got it today.

    Now I hope I can get it installed sometime soon, but first I have to turn this

    and of course it is Masters week, so when I am not splitting and stacking I will be watching golf :)

    Golf!? Motorcycles easily trump golf :D .

    Just messing with you. I agree Mike ships really fast. Also it will probably take just as long to drain and refill the oil when you are done, than it will take to swap the plates out.

    Got it installed tonight after some wood splitting and Masters watching :D

    I did notice something I never saw mentioned while researching this task.

    When I took the plates off the outer most two steel plates were slightly thicker than the other 4, 60/1000s of an inch compared to 50/1000s of an inch. I was curious if the replacement pack would have two plates at .060 and 4 at .050.

    It did have two plates at .060 and the other 4 were .048, I put the thicker ones back on the outside. I am not sure if it matters, since I never saw this mentioned in all the digging around I did.

    I am going to take a thick steel plate from the old pack and make a clutch basket holder tool for removing the clutch basket nut so I can play with my little MIG welder I got this year :wink: , if anyone wants one let me know I will make two.

    I was going to make one of those tools tool out my old plates too :D .

    I didn't even measure my steel plates, guess I should have. I just installed them and it worked.

    I wish we could go back in time, back when these old TXT bikes were being worked on instead of most of us dinking with newer pro models. Seems to me, I was told there is a thicker plate that "obviously" goes in first.

    That (question about plates and locations or thickness) is a good question to direct to old JSE on TC, pm or otherwise, I think. that is when he was even more involved with tinkering with the gasgas, even though he still does today.

    This is EXACTLY why I tried to tell people to get newer bikes. But, I am damn glad to know what you have learned fork wise, since I have a jt25 sitting in the barn... Saved me having to hunt and ask questions! :thumb

    There is a steel plate with fiber only on one side that goes in first. I did measure the all the fiber plates and they were all the same so I never thought to measure the steel ones. It is down awhile while I try to fix the forks so I I may pull them back out and measure the steel plates for peace of mind.

    I only paid $400 for mine. A new bike was WAY out of my budget. I have $139 in the clutch and not sure what to fix the forks yet. The other stuff I have done was only cosmetic and not required. But I agree as soon as I can afford it I will be buying a newer model bike.

    I got mine cheap too, it was going to disolve under a "lean-to" if we hadn't rescued it. But we've dumped handfulls of cash and "favors" into the dang thing. But it is perfect for 1st ever riders, even those that never rode even a dirtbike...

    I also measured the steel/fiber combo plate,it was .080 on both the old and the new pack. I did not measure any of the failed fiber plates that were falling apart, so I don't know what thickness they were and since I did not have a reference measurement I did not bother to measure the new fiber ones either.

    I have no idea why those outer two steel plates were thicker, but I imagine for the casual rider (95% of us) it will make no difference imho.
