Cure the wobble...

There was a video on this forum some time ago of a young chap trying out bananaman's heavily loaded bike in the USA and scaring himself with the front wheel wobble.

He he, yes that was me with the tank-slapper. I think I lost a year off my life that day ;) I was more worried about dropping the bike after the guys just arrived in the States for their epic cross-country trip!

Very Brave Mike, I would not have gone near it again.
Are you going to put an Hydraulic Steering Damper on your Bikes ?.
I have had a few Shakes, And got thrown over the top once, Not good.
Cheers Bill.

If you were Old Harry, would you dare to wobble while Marcus was in charge. A couple of winters ago Marcus had a front puncture while riding from Sweden but I don't recall him complaining that the steering did anything he couldn't control.

Yes he's a Strong Bloke, But I would not like to see him get hurt, We have all been lucky, But luck sometimes runs out.
Mike was worried about Marcus going up that ramp, Into the Truck, He was Right to be, Later in the trip, Marcus lost control at the top and it tipped to the side, It was on there Video.
I still do silly things, But I know I should not. Cheers Bill.

If you lighten the front end of a bike with Brampton type forks, you can quite likely cause the forks to approach a similar condition to the bad geometry of the Girdraulics. If you jack the front wheel off the ground those links will point down though not as much. The actual fork action of Girdraulics is not that different to Bramptons only the Girdraulics have more travel and the springs sit the bike up much higher. All these front ends can behave badly if the conditions allow it. In the video it looked to me as though the chap riding it was sitting very upright and arms straight out, if this shifted the weight even slightly to the rear coupled with all those panniers and top box, I can see how it would start a wobble.

Days of sitting on the tank in pillion mode are past I have the new longer pillion seat -but I suppose that puts the weight further back however I guess the new damper and steering stem will sort it all out

You are all very correct in your assumptions gents , but traveling back and fourth joining ships on the continent with all my sailing gear & tools for six month trips on a banana boat, then leaving the ship even worse with all the contraband, things made on board, like yolcalbro body silencers (sea water resistant brass looking stuff) and presents for Christine, then children Robert and Camita.
The worst time of being continually over loaded was the second month in NZ after the international when we did it all again with Camita on Roberts "D" Rap so didn't want to over load her and third day we cover 150 km on freshly graded iron roads , she had gone on ahead later rounding a corner she was stopped in middle of road and ahead of her was a road surface so churned up it didn't look right, when we finally got her to talk she explained a bunch of wild horses had just crossed in front of her.
The hairiest time was in south island returning on her 20th birthday from Milford Sound Camita being ahead as usual ,a tourist bus had over taken us but the road was narrowing just before a bridge on a left hand bend the road cambering off 20 to 30 degrees slowing down sufficiently to let the bus pass , the weight kept me centrifuged on that camber and it was only a mater of inches from the bridge buttresses that I was able to remount the road inches behind the bus , three bends later we were going through the Homer Tunnel that the bus showed us the way as it was pretty dinggy and rough surfase, all seemed OK back at Te Anau where the Von Tunzelman's had put on a wonderful spread for Camita and there younger son Reas there too, Twelve years later when revisiting on my own went and re-examined my nightmare moment,( no more nightmares) OK if I hadn't been so loaded the bus wouldn't have overtaken me.

PS next time I'll tell you about crossing a three in one bridge in Central America.
