    I am rebuilding a very tired TLR200 into a twin shock trials competition bike. Just for the halibut.

    I am wondering about the front forks. They are weak and crappy. I know there is no revalve kit for it and no upgrade other than new forks. If I got different front forks that were disc brake - would it still be allowed to compete in twin shock classes? In our local club there is only a handful of vintage bikes, and I dont think anyone would care. But it would be nice to take the bike to the states every once in a while and have a little fun competing.

    OK, so if disc brake is out - what kind of upgrade options for the (non-mighty) Reflex are there?

    thanks

    I'm not looking to upgrade the brakes - its the forks I want to upgrade.

    Common upgrades:

    1) Pegs lowered and moved back
    2) Change jetting to reduce lean running
    3) Advance cam timing
    4) Cut and weld frame to steepen steering head angle
    5) Battery eliminator
    6) remove lights, gauges, extra wiring

    This one belongs to one of the members of Mountain West Vintage Trials. It has a complete TY350 front end.

    Another option, would be the 1995/96 Fantic section front forks were great. There were many of these bikes floating around as parts bikes if you come across one. Seems like I saw a write up somewhere about this mod.

    I changed the oil in my forks and I think they are fine, but I'm not much of a conoisuer. Maybe check the springs while you are in there and see if they are within spec, i.e. haven't shortened up.

    BTW, I did a little comparo with my Scorpa 125 and the TLR today in the driveway and I've got to say I like that TLR. It's a fun little tank.

    Spoke to the nice chap at B&J Racing today and he said that putting some air in the forks to add a little compression damping could be an option. I ride down a lot of ledges and need some more bottoming resistance.

    Interestingly he did say that the stock spring rate front and rear should be ballpark for my 180lb weight. I may have to tackle that almost 30 yr old oil in the forks though.

    You don`t need air. Air is ment to be released not added too the forks. The forks can work fine. The problem is the axle is about the size of the old xr75. (actually the whole problem is it was not supposed to be competed on.)

    It interesting that the trick item now is to add valving to release air buildup in the forks. Back in the day the trick was to install Schrader valves and add air to the forks. I just trimmed down an 87sp200 for single track and installed schraders just for that vintage advantage.:wink:

    Back in the day we used atf or more atf and air. Nowadays we spend 15 bucks for a pint of `trick` suspension oil. I think the advertisers won.:D

    Get a XR200R front end, best IMO is 84-91, about 10" of travel and an aluminum rim.

    I found that mine works pretty good with 4 psi in each leg. I'm about 185 lb.

    Hey Chuck, will the TLR triple tree accept the XR forks, or do you need
    the XR triple tree?

    The forks will not work for trials.

    84 XR 200~free in Sedro Woolley, Wa. Have the brake hub but there is a tab broken off that holds the cable.

    On the air thing, I ran a 75 Honda CR 125 in three races in Oak Harbor in 1979 with out springs in the forks with no trouble. The blowtaco guys used to run air in their forks to keep the seals from leaking.

    Nice set of forks. Do you realize what these will do to a trials bike with 3 more inches of height and travel to a trials bike front end. At the best it would be a chopper. Did you watch the factory supercross guys last year trying just air and failing at it. Maybe you can give them some pointers.:lol3

    Lets see, the forks are in good shape. And I realize that raising the front of any bike would change how it handles, also anybody can take the old forks apart and make a spacer to limit the travel[and ride height]. And I didn't see one factory supercross guy running a sub 200 lb 39 yo 125 two stroke. And if I were to give them some pointers I would tell them to get ahold of you.:wave
