    Thanks. I had to make up for my piss-poor showing on Saturday. :huh

    I sorta figured that Sipapu would be a bit much for the ol' Cota in Sportsman. Hopefully I'll have OJ's pegs relocated by then so I can stay within 50 points of you or so. :lol3

    Garrett rode very well. Yer boy is definitely growing up! :thumb

    Chinese CDI units always work very reliably, and pretty much any of the 5 pin AC pit bike ones will work perfectly on the TLR. Short run on a dyno confirmed that low rpm power was increased a little, and eliminating the rev limiter incorporated into the OE Honda CDI, gave a good increase at higher rpm, after air box had been de-restricted.

    After riding the reflex in several events, jetting and `fixing` the air box,better pegs and looking at what `it` could become, it still is a piece of crap. Reworking the frame would make an awesome difference in handling.(for anyone wanting a good tlr this is a needed mod) But in the end this is too top heavy and under powered.
    Just comepleted a two day event riding our sportsman line. What a fun time, glad I was on the little cota 200. What a great little bike, funny thing is it sat in my garage for eight years unridden due to not being AHRMA legal! Time to get rid of the reflex and put some real brakes on the Montesa!!:D:clap:D

    If you are not interested in modifying the TLR to make it into a fun and competitive TS trials bike, I would completely agree it is pretty poor.

    For anyone not happy with the stock bike, I would suggest having a good look at the "Trials Central" Honda forum, where there are some very useful ideas to help with improving handling and getting more power.

    Looks like I'm fairly committed at this point -

    Yup, finally dropping the peg mounts an inch. I have a mere 2 weeks before the next event to get it done.

    Hey if OJ is not together by then, there is always the Team TY...

    Garthe, you just shut your porky mouth about the mods. I told you this might happen! :D

    Look how skinny that pig would be without pegs! Just stand on the seat. Would never dab cuz it will be wayyyyy to far to bother. (ps I sold mine last week! POS! ):D
    VIVA MONTESA!!!!:lol3

    It takes around an hour to alter the rest mounts on a TLR...........there have been several how to do threads on this job on the Trials Central forum.

    I had the guys in the fab shop at work cut out some frame extensions with the plasma cutter. Much nicer than I could have done with the torch. A bit of grinding and it's almost there -

    [​IMG]



    Locate crudely, and weld -

    [​IMG]


    I got so busy fabbing, I did not stop for many pics. Welder crackling, 94 Rock blaring out of the garage, cold Tecate in hand (yes, while welding :lol3), I was in the zone. Welded up the peg bracket, slathered on some Mopar Hemi Orange paint to hide my sins (I'm not the caliber of welder that Grizzzly and Gordy are :cry), and we have a....left footpeg mount!

    I tried to capture the height difference in this shot. I guess I'm not the photographer that NMTrailboss is either...

    [​IMG]



    The peg is much more inline with the rear axle centerline. It should make a big difference in handling -

    [​IMG]



    Just a (as much as OJ gets) beauty shot. Mayhaps its time to replace the seat tape. :lol3 -

    I'll tackle the right peg this weekend. Pics (maybe) to follow. :D

    Uh, let's see. Grind and weld one extension on both sides, locate and weld one peg mount, not scuff or clean the area before paint....... 72. :lol3

    Yeah, way too lazy to pull the engine. And I'm well aware that Montesas don't need mods. I have 3 of 'em that work just fine the way they are.

    And did you mean to say DODGE van?? :evil

    MUCH better control (at least test riding it in the street in front of my house). Next weekend is the acid test.

    More to come! :evil

    I like that old style exhaust. Simple light weight. I can see why you kept the air box heat shield!:rofl
    So did you ride the 4rt today?

    I figured your eye would be sharp enough to see the partially missing exhaust. There may be more to come with that also. :evil

    And yes, I rode my Montesa today. First time I've ridden in since the December event. :huh

    The fun continues.

    I got around to installing a #40 pilot jet and the Honda upgrade jet needle/air mixture screw kit that I had lying around for years. It's the same upgrade that Taxonomy posted in his Reflex jetting fix thread. I bought a #100 main for it, since the smallest jet I had that would fit was a #130. A bit big.

    I had installed the pilot jet before heading off to Sipapu last weekend for our June event. The off-idle response was noticeably more crisp. Earlier this week I had replaced the air mixture screw. Even more crisp. Today I dragged out the needle kit -

    [​IMG]



    Old needle on the right, new on the left. After installing it, I replaced the main jet with the #100 I bought. I was more than a little surprised to find a #82 main in the carb. OE jetting was a #92. No wonder this thing was so weak. After the carb work, I removed the airbox restrictor -

    [​IMG]



    Bolted the tank back on and went for a little testride. WOW what a difference! MUCH better off-idle power, and the sound from the air rushing into the unrestricted airbox when I open the throttle sounds really cool. Ran it 'till it was good-n-boiling hot (not too hard to do on a 95-degree day) and 'ol OJ never even hiccuped. :clap

    I did notice a bit of a concern while I had the tank off. Looks like the frame tubes welded to the upper spar coming up from the engine cradle/swingarm mount are developing cracks -

    [​IMG]

    I'll break out the welder next weekend and remedy that situation. The good news is that the footpeg mounts held up nicely to what turned out to be a brutal weekend for the ol' bike. OJ got beat up pretty well by the log crossings and "V" rock gates that not only scraped up the new footpeg mounts, but also stopped the bike solid on one particular obstacle. That, and a SPECTACULAR backflip (OJ spun over 2-1/2 times!) on a hillclimb section (WAY too much throttle in second gear, never saw the bump hidden in the grass that sent the front end skyward) that resulted in....this -

    [​IMG]



    Yup, broke the front fender. It was possibly the very last "in the package" brand-new fender in North America. :cry

    Even with all the carnage (and exceptionally poor riding on my part), OJ still managed to win both days and get the Overall -

    [​IMG]

    All the Overall competitors got a nifty Sipapu ski area sweatshirt and button. I got the button and a half-pound of homemade fudge courtesy of the ski lodge. I enjoy the fudge a lot more than I would the sweatshirt, and I have to admit I really like the chintzy button.

    All that being said, don't read too much into the win. I was the lone competitor in Twinshock, with Lineaway's Montesa having crunched a crank bearing the day before the event, and the rest of the Twinshock competitors not even showing up to Sipapu. I really don't like competing in a class all by myself. That's not competition, it's just a ride so my scores really suffered. My head was just not in it. However since Lineaway is like 4 times a better rider than I will ever hope to be, I am going to selfishly take the points. I turned down the trinkets for each day's win (if you could call it that), and had some homemade fudge instead. I predict that Lineaway won't be down for long, though. I'm going to enjoy being ahead of him in points while I can. :uhoh



    Anyhoo I celebrated OJ's overall by polishing up the 'ol wretch, and giving the seat a new coat of duct tape. The old "cover" was starting to look pretty ragged -

    [​IMG]

    Lookin' good. Better, anyway -

    [​IMG]



    The more improvements made, the better it gets, I'm starting to ponder hootchy-ing up 'ol OJ. Miss Bitters votes no, it would tarnish OJ's scruffy image. I'm not convinced. Not yet anyway. We'll see.

    More to come! :evil

    Your welcome, and thanks for the kind words. Since the coors can got me to ride expert sunday. I was a little out of riding condition. I knew I was in for a long day, when last years class winner was punching sections on the first loop! Riding twinshock is a little less demanding for sure. That`s all right, next year when my son moves up to semi-expert the class will grow by two!!:lol3:rofl
