The only spacer that's in your swingarm is a tube that goes between the bushings - which are pressed into the swing arm pivot. They aren't selective - and tightening the through bolt SHOULD pull it all together ...... Same with the wheel spacers - no selection here ..... and tightening the spindle should pull it all to "zero" ..... I want to what what voodoo went on there as well ..... I'M thinkin' someone just found a loose bolt - or took apart, scratched their heads and inadvertently put it back together right ..... it's a mystery!
Yes, definatley what I found on the swing arm, no play at all at the pivot, flex was at the rear of the swing arm.
The visiting RE engineer had the entire rear suspension dismantlled, including the rear wheel, hub and the front sprocket. He found the wear pattern on both sprocs equal and hence they were put back as before. He then checked the spacer of the rear wheel and decided to change it, as also the spacer in the swing arm. Refiited everything back and I tested the bike till 130 KPH/81 MPH. It was stable, in fact I did try to weave it at those speed, but it did not oscillate. ;DNow for the tricky part (what the engineer did not know). The attending mechanic unknowingly added few shims on either sides of the rear shockers (upper bolts), cause he thought the gap was too big for the bolts to hold it tightly.If you guys know, the Indian version comes with a seat pre installed which slots with the fastners where the rear suspension goes and its front is bolted the fram below the front seat. My two cents, the removal of the rear seat created a gap at the rear upper bolts which allowed the rear supension space to pull on either sides, creating the oscillation. I also saw the upper bushes of the shockers pulled sideways. Let me know if this theory holds any water.
Bradey:Time for champagne ! Glad to hear you can ride it the way it is supposed to be - Hey, you gaddaa waalaa and Hero Honda, move over for the Bullet is coming at 80 mph ! Do you think it is the replacement of spacer in swing arm that solved the problem or it is the shims on the rear shocks that cured the problem ? If you remove the shims from rear shocks, can you see if the oscillations come back ? Or you don't want to try it and just want to enjoy the smooth ride ?
I find that really odd ..... the section of the swingarm that sticks out past the triangulation of the pivot, shock bottom and shock top is pretty short - and PIG IRON .... it shouldn't flex - even when riding pretty hard. What kind of monkey motion did you get there? Lemme know. I'm QUITE curious at this point ......
Let me clarify, yes the axle plates and shock mount area is pretty Stout.What I mean is the week design from that point back to the pivot tube.It flexes, no gusseting or support, or arch shaped design at the pivot tube. It's basically just 3 pieces of pipe, welded in the shape of Japanese arch, Know what I mean? Like a roof on a pergala or trellis. I think it's too long for that shape, it's longer on the C-5, then on the G-5, so I read. Take one out, and push it in at the axle plates, Like Suzanne simmers does with her machine, and you'll see what I mean.
Champagne for him, not for us quite yet. Still trying to figure out what he means?
You could always put on some struts and run her ridgid to see what tells you.
