  1. This weighs 875#...38# in the front...
  2. And THEN... checking everything after having those say something MIGHT be loose... It got considerably colder here (as all this came on) and although all is tight mechanically, I wondered about the rear tires (which I only run 15# in). Checked and they were down to 8.5#!!! There's a "loose" spot! Took them up to 15# and there's no HINT of a wobble now! Amazing how things all have to be in tune in order to work right!
  3. Thanks guys for the suggestions. The rear camber is zero (checked with a level on the wheels- optical illusion). Zero on the toe as well. I'll look into some accurate figures on the trail next week but as it stands in construction, I had 1 7/8" trail with the ability to increase that to about 3 1/4"- I have tried adjustments there to no benefit. I used the top part of a Gold Wing frame, steering head- I added 5 degrees rake to that so I'm not sure that really comes into play. Yesterday with the stiffer shocks on it I did an experiment. Drove it thru my neighborhood at 15 MPH for about 2 miles (wobble would start to happen @ 20), kept it to 15 and no wobble then took it out on the higher speed road and no wobble occurred - go figure...

  5. Greater the air pressure, less wobble- I'm at 38 pounds now. 170/70-16 Shenko in the front. It's a round tread tire so not much rolling resistance. Everything in this is brand new and tight. Really think this relates to either the front tire or the angle of the front swingarm (on the fork).
  6. Hi Blackjack- new here- you wrote some interesting stuff back a few years on the "leading link, Earles fork" topic... would sure lie to pick your brain on this!
     

  7. Oh yeah- and despite being a "grease spot" I'm a monetary supporter here>
  8. Rake is kinda a moot point as long as the trail is correct to the rake. Trail is 1 7/8". It steers great- Thanks!
  9. Hey- I joined this group SPECIFICALLY because I found this thread and have built an Earles fork for my trike. All started out pretty good- and then slowly a low speed wobble began to show up (not running a steering stabilizer). At first it was just annoying, crack the throttle and it would go away. Then it became more pronounced and found myself fighting it for the first few mile after which it just plain wasn't there for the rest of the day, repeat the next day though. THEN I decided I needed some softer springs to keep the wheel in better contact with the road surface and it was FULL ON wobble- not just low speed any more. Switched back to the stiffer shocks, that helped but it was still there... fitted a stabilizer from a big Suzuki crotch rocket- didn't change anything. The pivot point on the swing arm is above the axle center point. Info here that Blackjack gave says the swing arm needs to run uphill to the axle-is the angle more critical or the swingarm pivot point more critical? I want to fix this cause I love the trike but would rather do it once than many times over! Any and all help appreciated! I have a 5 X 16" wheel on the front so I COULD put a flat tread car tire on it as well... Pat
