  1. Your octane will drop if you remove the alcohol from your fuel,plus the petrol that remains will likely have water absorbed into it. This water will compete with your oil for adhesion to the metal in your engine. https://www.epa.gov/sites/production/files/2015-09/documents/waterphs.pdf I think I would search out a ethanol free fuel and keep the tank drained when not in use.
  2. Make sure your carb is adjusted to very smooth running at Idle and just off of Idle,if the setting is off and the motor blubbers or stumbles it will aggressively respond once the throttle is opened up father and the next metering component of the carb comes into play. That said it is also important to think of your clutch lever as a second “throttle” twist grip sets the power level,clutch lever feeds it to back tire.
  3. Buy 2 vehicles,cheap economy car for everyday and used full size van to haul bikes and camp in. You will save on hotels on 2 day event,can be outfitted as a rolling workshop with all your need in it. I prefer to buy a bit of fuel in pursuit of comfort. Ram Promaster full size for events,Dodge Caravan 3.8 PUSHROD engine for daily driving(I haul a bicycle in minivan to ride on my lunch break,so enclosed transport is best,and hauling my prized two wheelers on the back of vehicles Is a non starter for me in this cellphoned inattentive driver world),including hail damaged exterior plus rust. Comfortable cruising at 85mph. 20 mpg U.S. is good enough for me(maybe I can switch display to British gallons)Very reliable vehicle so no stinkin’ high repair bills. Pushrod engine rule. In a pinch can haul trials bike in minivan. Liability insurance only on minivan. 20mpg also looks good to me because my previous daily was a lifted Grand Cherokee,12 mpg,but not quite that bad due to 35 inch tires fooling the Speedo.

    I will be off work that week. Would be glad to help.

    TXT 321 Forks

    When are you planning to do this? I can come by and help you if you’d like. I won’t be doing any riding until my shoulder is fixed so I plan on doing a lot of bike work in the meantime.
  6. Thank you for the info (-: The Ozo Experts do not come apart at both ends like the Ozo Pro do,I was thinking it would be easier to switch to emulsion and have less pressure rise as the shock compresses due to the increase in volume with the IFP out. Maybe run about 10-20 PSI to help the seal at rest but not rise as much when compressed. I am not a shock guy but I assume your mods free up low speed damping more than high speed? I will have to see if Experts are the same inside when I get them apart. Sounds like a project I can do while recovering from shoulder surgery once I need to start moving again this winter. I hit on the idea spring rate and preload spec last time I rode the SWM while doing Trialsmaster duties, I was trying to get good turning and first had the preload up too high which killed stability and made it tiring to ride,Backed it off a single groove and old girl became really sweet in both stability and turning ability. Made her so good I was able to ride it much more aggressively and what do you know,clutch started slipping, New discs are coming from Martin..Forks need work too,feels like internal friction and too high of spring rate,already have Redline Like Water in them and still too slow,have installed Kawasaki Super Sherpa accordion boots in place of wipers which may be adding to spring rate progressiveness but fit like they were designed for them.
  7. How did you position the floating piston on reassembly? If running them body upwards is there any reason that converting to emulsion wouldn't be ok? Seems for a trials shock emulsion would be good. Tricks to reduce damping secret? I put some basic black OZO on my SWM mainly for appearance but they are surly too slow for good action. 40 LB spring couldn't get themselves pushed back up,50 lb seem good but still slow.

    Lanyard Fix

    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.

    SWM Modifications

    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.

    SWM Modifications

    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.
  11. By the looks of it it appears you will be punching scores next weekend rather than riding it.
  12. 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.
  13. 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.
  14. 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.
