I asked Kane how many horse power & what kinda speeds he gets out of the bmw but he didn't know. He hasn't bothered putting it on a dyno.

I was watching how low he was cornering on this tight track & the heads still had a fair bit of daylite between them & the road. I was surprised.

The engine appears to have been raised in the frame.

The Guzzi has way more power I think. I watched as the guzzi took him on the outside of one the back corners. I asked Kane how many horse power & what kinda speeds he gets out of the bmw but he didn't know. He hasn't bothered putting it on a dyno.

The Guzzi runs methanol (or used to) and Bernard rides it pretty hard, at Greymouth Kane was leading it for a bit

Correct it has been, not sure if he runs the short piston/barrel kit

Next stage looks like I will have to make my own rear subframe. GSers

[Padmei]

How much rear travel would you have on that?
Does anyone know the max you can get out of a mono & para?

[GSers]

I have been at the front universal yokes with the dremel and relieved the articulation angels. The 1150GS ADV is rated at 220mm of rear wheel travel. I am going to restrict this to 250mm I could get another 10-15mm but I think 250 should be OK The front forks have 300mm of travel but vertical wheel travel is 275mm.
I searched the net on the question and the 4WD guys are running up to 25Deg out of universals on there drive lines I am running 22Deg so I think it should be OK time will tell I suppose.

Thanks Aslan, how is your shoulder going? What did Howie do to his leg? You guys have been knocking yourselves around. I hope I have had my share of that when I was younger. Back to the bike yeah I am happy so far, had a stand on the foot pegs today and I was surprised that the bars felt in the right place I might just get some risers to lift them up abit. I thought they would have had to come back towards me a alot but I had to push the bars forward so thats good. It feels small.

Howie has broken his ankle....

"broke my ankle while down south for the
db1k. "

[Pampera]

So glad I reverted to a two valve GS after a decade of fuel injected GS singles!

Gearbox (1993 R80GS) removed today to find and rectify the source of noise, glittery flakes in the oil and sludge on the drain plug.
The gearbox input shaft splines needed greasing anyway.......and a good chance to check electrical connections, reseat the heat sink etc while waiting for the diagnosis and then the parts to arrive. Hope I don't need this corner of the garage for a few weeks.

Pampera, there was one on trade me the other day for sale not sure if the R100 and the GS are the same but you can never have to many spares?

Hi GSers, I took an impact on my Ankle on the same part of the ride Where Aslan hurt his shoulder. I didn't actually think it was that bad, like a couple of Nurofen Morning and night for 2 days then no more pain killers. Rode for another 10 days around the south island, then back to work and that was when the Ankle started to swell up quite bad as it was out of bike boots. Xray showed I have broken a bit of bone off in a non load bearing area. So in a cast for 6 weeks.

Your bike build looks like it is progressing well.
