What’s this thread about:
I’ll use this thread to document my rehab of Gus. Padmei’s doing it, why can’t I? And hopefully we’ll get a community of GS / airhead owners here.
This is what Gus looked like when I bought him in Jul 10.
And the second picture shows what he looked Jul '13.
Gus is a bastard in a number of senses. Old vehicles need names. Cursing a thing
just doesn’t seem right. It’s always a bitch or bastard. And Gus is positively geriatric.
Why I bought Gus:
I’m a long time airhead fan, having owned a ‘78 R100RS,
(there's a separate thread on that now), ‘83 R80ST, ‘86 R65, & an ‘88 R100RS
. In the ‘90’s my wife & I travelled Europe on the ’78 RS. We spent about 3 yrs alternatively working in London, then travelling the summer months. The trip back home was supposed to be an extended tour through Africa. I actually purchased the ST for that trip, bought a Acerbis 43L plastic tank for it, but alas it was not to be. I wrecked the RS
when a van did a u-turn on me, and then the couple we were to go with had a head-on with a minicab. The consolation prize was a trip to the South of France, & then home. Both the RS & the ST were imported back to NZ, but in a moment of madness I sold the ST to allow the purchase of a lounge suite. Which is now almost dead…
I’ve had a couple of goes at getting a GS since, but this hasn’t really worked out. The last white RS was supposed to be one, & the KTM 640a was close (in a sort of ‘Paris Dakar’ way). The KTM was a brilliant bike, but my experience was KTM parts support was lacking. Whilst I am sure the whole package would do big miles, portions of the bike seemed to be higher maintenance then I am used to (Hi ClintNZ & Warewolf!!).
One thing I missed with the KTM was the ability to load either Katherine or Mandy on the back & to go out for a day trip. The KTM was really a one person bike.
Airhead GSs have been on my Trademe favourites list a long time now. I’ve seen a few cheaper GS’s come up (Newguy, Barrie & Padmei). Padmei, you don’t know how lucky you are to have your bike. My finger hovered over the buy now for quite a while the night before you bought it…I have finally decided that I needed to build the bike I had lusted after for 20 yrs.
So where is this heading?
I have agreed with Mandy that I can spend the proceeds of the KTM sale on Gus. Given where the NZD has been against the Euro, GBP & USD I decided to buy some of the larger items now rather than wait. So I have ordered a bunch of parts from Motobins to allow repair of Gus & the RS, Touratech pannier racks & a 43l Tank (I like big tanks & I cannot lie...), to change the handlbars & risers, & have ordered an Ohlins shock from Robert Taylor at CKTechnical. Robert's price has been comparable to import (before freight & GST!), but I get the shock build to my specs.
The wishlist is somewhat more advanced....
To make this thread a bit more manageable I have started & will expand on an index - green text are links. For much of the maintenance & modification I haven't always included links, largely because this happened over a number of posts or pages & may be predominantly text.
