    Elsewhere on the forum you will see where I have dedicated myself to ride this awful pile in NMTA's Twinshock class this year.

    http://www.advrider.com/forums/showthread.php?t=767608

    It is an effort spearheaded by myself to see the Twinshock class succeed here with NMTA. Since this bike has been (at best) thrown together, I thought I would at least shore up a few shortcomings for the upcoming season.

    I started by dragging off the back porch. I had dumped it back there after winning my class in the McClanahan fun Trial last fall.

    Accepting the 1st place medal last year with quiet dignity and grace -

    Anyhoo, I decided to weld up a positive stop onto the OE kickstarter stop bracket. The OE bracket never really worked that well, allowing the kickstarter to rotate past it on multiple occasions. Since I am NOT going to split the cases on this heap to replace a broken kickstarter gear (I'll junk it first), I decided to nip that problem in the bud.

    The well-worn stop bracket -

    I cut a piece of 3/8" square steel stock, and welded it up -

    Some cheap no-name rattlecan black paint hid my goober welds -

    While I had the MIG welder out, I figured I might as well widen the stock footpegs. I had lowered them 4 years ago when I assembled this mess, but never got around to making them more proper Trials pegs. I knew exactly where I had left the other set of 'Flex pegs on the shelf, along with other leftover 'Flex parts. I figured maybe an hour's worth of cutting apart the leftover pegs and welding them onto the bike's pegs would be well worth it. Just one problem....

    [​IMG]



    Yup, one peg has gone MIA. I gave up looking for it after an hour-and-a-half. It's gone, no clue where it got off to. :dunno


    While re-installing the kickstarter stopper bracket, I noticed that the spark plug cap had a bit of a problem -

    [​IMG]




    Removing the cap revealed another problem -

    [​IMG]



    Hmmm. I really should replace that spark plug. It has been in there since I built the bike.

    Naah. I straightened the plug pin with some pliers, and replaced the cap.

    [​IMG]



    The duct-tape seat cover is looking a bit ratty -

    [​IMG]



    So in the spirit of OJ, I left it alone. I gave the old heap a quickie bath, lubed the chain, and put it away for the evening.

    Lookout NMTA Twinshock, here we come! :evil

    There is no real need for welding extra parts on the kickstart stop............to cure the problem on your bike all that was required was to loosen the kicker clamp bolt and tap the lever inwards fully onto the spline.

    9-42/44 gearing works well on these little bikes, and there is no need for enormous back sprockets which are quite susceptible to damage.

    Steepening the head angle 2 degrees moving the rests down and back a little improves steering handling a great deal, and with a few simple mods to intake and exhaust a TLR is reasonably competitive against modern bikes in easier events.

    Been done multiple times. The kickstarter lever always made it's way back out to the end of the shaft, and usually at the exact wrong time. The welded bracket took up a whopping 45 minutes out of my life, so I call it good. :D


    Tried that. It was still a bit speedy, since the XR200 based engine does not have a really low primary gearing. OJ is a bit more versatile with the low gearing, especially in soft sand (where most of the next Trial is set, BTW). For long hillclimbs, I just upshift.


    I have a very nice 4RT for modern events. No desire whatsoever to cut and weld the frame on OJ. Ditto for intake and exhaust mods. The pegs have already been lowered, and widening them is in the works. I will modify the upper clamp for some Fatbars soon, along with raising them a bit. As for a bunch of hootchie mods after that, pass. It works just fine in it's own magnificently crappy way. :lol3

    Have worked on an awful lot of TLR's and never needed to do that mod on a kickstart ever............

    A guy I know ran a TLR in the UK twin-shock championship a few years back and was on 9-42 gearing. Much lower than that means 1st gear is much too low for most sections, and the wide ratio box means 2nd and 3rd are too high for modern type TS sections we get here in the UK.

    If I ever ship OJ to the UK to ride, I'll keep that in mind. The gearing works just fine for Trials here in the wild, wild west. :lol3

    Must be some awfully tight technical sections over there then............I find 9-44 is very low, and means you cant really use 1st gear for anything other than really tight turn type stuff.

    Tore into this `new reflex` today. It was parked for 10 years. Took about 4 hours of soaking to get the slide out. Gonna be tough to get this rideable by this weekend.:lol3

    Sounds like you will need a new carb............pit bike ones work fine and are very cheap from Ebay.

    Why bother? Your Cota 347 is 10 times the bike the Reflux will ever be. :evil

    In actual fact a TLR with a few simple mods is far superior to any TS Montesa.............the stock TLR though is pretty awful, but its easily improved without spending much money.

    Now I`ll give you the reflex was better than my 1971 247. But I have come to the conclusion that you are `touched` in the head and should seek some proffesional help. My `81 cota 200 as old as it is with no mods is a much better trials mount than a stock reflex. And I had the pleasure of owning a very nice `84 cota 350 that I wish I never sold. It could not compare to a mono yamaha, but would be great in the vintage class!

    You are quite right to agree with me that the stock TLR isnt much good at all. However a TLR with a few simple/cheap alterations is far superior to any TS Montesa, and I think to some extent this is proved by the fact that modified TLR's have won UK twin-shock championship rounds, while to the best of my knowledge no one is even using a TS Montesa in these events (due to them being heavy, uncompetitive, with difficult/impossible parts).

    I would suggest you have a ride on Bob Ginders modified TLR if you get the chance, and then I am 100% sure you will then agree that a modified TLR is an awful lot better than the old dinos you seem to favour.

    I see you are an expert in TwinshockS, but you do know that the "TLR's" you are probably referring to is NOT even close to what was ever imported in the USA/canada, RIGHT?

    Over in your country, and the rest of the UK? You have a "TLR" which actually IS a trials bike... and look more LIKE this pic[​IMG]


    But, over here they were street bike/enduro loosley based on that TLR over there's trials bike design. They weigh a ton stock, the POS's shiped with steel rims...

    [​IMG]
    THis picture is missing a lot of the lights as well...

    I doubt like hell the montessa 2 shock bike you have in your mind, could outweigh the TLR (AKA Reflex as they were called) and most of us that have one (I have 2) call them reflux,,, even if I was sitting on the montessa.

    Bob Ginders modified TLR is based on a Reflex, and nearly all of the alterations are things that anyone can do pretty easily. A completely stock Reflex with very minor changes, will work well enough for beginner level riders on easier sections, and will improve riding skills far faster than any modern bike, and will have cost far less money than going modern.

    Reflex has smaller diameter fork stanchions and steel wheel rims, but other than that its pretty much exactly the same as a TLR, and these things are unlikely to make a scrap of difference to how well the bike performs in easier events. Neither the TLR or Reflex is a true trials bike, but either can be improved enormously with a few easily carried out alterations.
