    Due to the elastic I've had a few ping off my wrist....luckily we've managed to find them again after a bit of hunting... I've swop the elastic for a shortened boot lace about 8" long so there is very little spare lace hanging down asking to be caught ...works for me and as the elastic ages it tends to stretch so if you need to shut off in a hurry you can't just flick your arm away.. With a lace the emergency stop works every time!

    I tumbled off a drop last year and the tether got snagged on the bike,it stretched and snapped,if it had been a boot lace possibly could have injured my wrist or pulled the bike down on top of me,just something to think about when you make a stronger tether.

  2. First,sorry for the dirty bike,has just done Trialsmaster duty and got parked into the corner as I needed a bit of a break in thinking about trials...

    I actually kinda like the narrower side to side width as it allows easier access to the end of the footpeg as I lean the bike. wouldn't mind a bit more for and aft width but also like the look of stock pegs so just not worrying about it right now. 

  3. Instead of welding on the chromoly I made some plates from mild steel to relocate the pegs. Didn’t want to go radically back myself but it would be simple to make multiple plates to experiment with different  positions. I utilized the stock footpegs for kicker clearance. Oh,and don’t go so low on the peg position that the saddle contacts your leg above the knee when you lean the bike into turns as it will pull your body inside the tire contact patch.

  4. Picked up a RL250 a bit back for a future project and wondering if it would benefit from a longer header pipe? It runs very smoothly but I like a rorty engine that jumps with a slight twist of the throttle,I know that's contrary to common Trials theory but I have a SWM to ride when I need traction in adverse conditions. I had a 240 Fantic and never felt like it was too Zappy and find that type of power fun. The Zook seems to be soft down low then comes on in the mid range. Haven't had time to check the timing or compression(Feels good to kick through) It looks like every other trials bike has a longer header pipe than the Suzuki's short U-turn.

  5. A exhaust that has carboned up will choke the top end,possibly to the point of causing detonation. Symptom is a loud exhaust as it clogs all the "pores" of the silencer and creates a 4 foot straight pipe effect with no exhaust tuning. 2 strokes do not care for straight pipes longer than 10-12 inches. What year 290? I have put the later model repackable exhaust on a 2011 and a 2013,requires the matching header also.

    Hi

    This thread has been a very interesting read

    Are there any updates on the SWM project?

    Did you end up making the clutch any lighter?

    Did you improve the suspension?

    Ian

    I had this bike out on loan to a buddy for a couple of years,just got it back a few months back. It will get a good going through before the next riding season. I intend to replace the cables and work with the brakes some more. The suspension is still very slow, filled the forks with Redline Like Water buy haven't had it out since.I bought it some OZO shocks from InMotion but they are too slow to suit me also. I will try some things to get the OZO to work before abandoning them.

  7. We run our Fun Trials events as "Gate" trials http://www.wmta.us/scoring.html

    This allow riders to chose their own challenges,it's a weatherproof trials as you can just choose easier gates if weather is foul. Riders can't get upset with Trialsmasters nearly as much,and it makes for simple observing,any dab and no score for you in that section. Theoretically could be a safer trials but human nature seems to make guys just have to try the tough stuff (-:

     **** Billy, they just mount the bike backwards and sit on the bars! Don`t tell me you never rode a bike backwards? I started on bicycles and moved up to full size bikes. In the seventies there were a couple of guys that did this for a living in the states. Mainly doing simple things, but some could do high speed wheelies. Being right handed I sometimes crashed. At pushing 60 I only ride bicycles backwards anymore.

    Mr Backwards!

    I saw him jump 5 cars sitting backwards when I was a kid. let me tell you,that Triumph was thye sweetest sounding motorcycle of all time!. He could flat track it backwards too. I believe he used to hillclimb it backwards also but I never saw that show.

  9. Break it up into to steps,start by just practicing the wheelie into the rock/log/whatever and it's ok to stop with the front brake,do the wheelie early enough that the front wheel drives into the obstacle. Get the feel of the fork compressing into the log/rock and rebounding,that's when you give the bike some help and jump yourself up and then push the bars forward. 

  10. The noise reduction system of the rear silencer is based on the Helmholtz principles using different volumes' and different sizes of tubes. As it is constructed now it works for all noise levels that comes from the engine. You can leave the system too as it is as build up crud can't effect it much.

    Anyway the rear silencer build up a permanent resistance of "air pressure" against the complete exhaust system that is mounted before the "chambers" and tubes. Thus providing less noise but too restricts the performance here the build up of motor revs., one of other reasons the bikes with this era and silencer react/respond so slow to throttle.

    If you want that the bike react faster but deliver as less noise take out all baffles and tubes and place a hole tube instead through the complete silencer. The diameter around 25mm. Then fill the hollow between the hole tube and the rear silencer well with insulation, the modern stuff works best mineral insulation less good.

    But the insulation will soak up oil residue and after a time your bike will sound louder and you have to replace the insulation (the backdraw) but the engine will respond better (the benefit).

    Now it's up to you?

      

     

     

     

    MX silencer 25mmx250mm long really woke up my 320TL,not really loud,has beefy sound. I did really like the quietness of the stock system,If just trail riding I would stick with quiet. 

  11. It's a 83 pro with a clouded history of origins ... I know the bike was left here after the WR.in texas that year, and was sold as a used competition motorcycle days later...

    I've got the paperwork to back that up , But have never been able to determine who's bike it was . and it isn't a "normal" 240 at all , compared to other ones I've got ...

    15 Pics from World Round Texas just got posted in my Facebook "Trials Riders" group,surely on of the Fantic pics is of yer bike (-;

  12. Haven't ridden my 2016 250 enough to get the filter dirty but in every other aspect it is a step above the rear tank bikes,turning at full lock it just feels totally composed,engine pulls noticeably stronger(Thinking about adding flywheel,but will put in more time on it first) Suspension better than a 2011 or 2010(I don't have enough time on 2012-2015 to fairly judge) Very happy I upgraded(And was able to pass my 2011 250 on to a new rider)

  13. Geez,Your supposed to invite me along when you are doing some Interesting trials related activity!

    BTW,SWM Jumbo is going to turn out to be a sweet trials bike,got it running and rode it some in the yard,feel good about spending money on it now.
