Circumnavigation of Oz

Funny story that cam, the shocks are off the 1981 Jota, ex Chris aka Woody. One spring was up one way, the other the opposite. I lent the shocks to Will, he swapped the spring around to make them match. Will is now playing with Carlo's Nitron rear shocks, before he takes the plunge on a new set. I was very happy with the handling up the twisties on the old road. I was a bit worried that the lowered pegs might drag, but with the raised ride height, no problems.
 
I can drag a peg on my 3c with the rearset pegs lowered 30mm, but it takes some confidence in the surface of the corner. It's rare for me to do it on random roads. It also helps to have pivoting pegs as well.
 
Good to see her out on test, Marty. Can't remember my fuel range, but reckon better than 250km. Exhaust will have to be tamed if you want to avoid hassles with the law in various parts of the country. My SFC 2/1 was transformed by adding a straight (non-tapered) canister with the same OD as the end of the 2/1 mega - the cone fits into the canister end and a perf baffle tapers from start of mega to end of canister, baffling material squeezed in around it. Looks very tidy too. Can take a pic if it helps.

S&W used to fit their shocker springs that way, most winds at the bottom.

OK, in reality it probably makes bugger all difference which way up the springs are. I just put the more tightly wound end at the top to reduce unsprung weight by a few grams.
There may be a good reason to put the heavy end at the bottom (spring harmonics perhaps?) but until someone tells me what that reason is, I'll keep doing it my way.
My Benelli Sei avoids any confusion by having the tightly wound coils in the middle of the springs.
 
Marty, good luck on your circle OZ trip wish I was doing it too.

I'm not a big fan of plastic jerry can fuel containers eventually they fail lots of vibration going on on an SF and considering the thousands of K's you will be covering you might want to rethink that choice. I have attached a very grainy old picture of a setup I used way back when. Plastic Jerrys as panniers but a metal fuel jerry can sitting on a rack supported by the passenger peg, it never moved, it never failed and was always there when I needed it. I built a support wrap-around loop that was attached to the same rack that supported the panniers, no-hassle I could just lift the can straight up and off the bike, could even fill it up insitu on the bike. HTH good luck on your trip mate, Cheers.

My take on the spring orientation is that the tightly wound end will compress first. Therefore, by placing the 'tight end' at the bottom prevents the whole spring moving with the suspension travel as would happen if mounted the other way round.
But I guess in our application it makes a gnat's dick of difference and comes down to aesthetics.

Sure about that

So after a few whiskey's here is the definitive answer not.... as Ooh! This is yet another one of those controversial topics.
It seems there isn't much documentation proving either way, so if you go just by un-sprung rate theory well it equates to 3/5th of fuck all..
Got no idea what that is in metric and to be honest cant be bothered.

So after many hours searching tonight on the web in between the odd glass of good ole Irish, I couldn't find a definitive answer.
Hyperpro (who make new progressive springs) say that the tight bit goes at the top but Ikon who now manufacture modern Koni still put as per Koni with the tight at the bottom. In actual fact also found that Yamaha (who make the stock fork progressive springs) say it goes at the bottom.
If I read the Racetech bible it tells me progress springs make no sense as all springs are progressive................................................

So guess at the end of the day its another one of those oil threads or was it tyre or was it ???

So the bottom line is that it seems to be the same here: some say top, some say bottom.
 
A support vehicle is a great idea. It'll make the riding more enjoyable and the logistics a whole lot easier to deal with.

I'm jealous. I'd be very tempted to come with you if I wasn't booked in for 12 months of anti-cancer immunotherapy.

Who doesn't like a good road trip?
