Tank slapper

[IMFASTTOO]

I use to be able to do it all the time without issue. I put a new tyre on and picked up a screw in the first 100 ks.... well I plugged it(don't like to on the front) and rode the bike accordingly. Well I took my hands off the handlebars at about 80, nearly had a tank slapped!!!!
Spoke to my tyre guy and he said the plug would be enough to throw off the geometry of the wheel...... so I asked weather a loss of a weight could do it, yes he said but road surfaces (potholes) can also change the rims geometry.....
Food for thought. I alway keep one hand near and if I need to relight a smoke, I pull up!

FIRST of all you dont want to ever take your hands off the handlebars period and you do need to balance the wheels and if your using a cartire you know your looking for trouble and expect problems

Ride on the opposite side of my the road to even out tyre wear

Well, I was referring to a balanced, no-hands, straight line ride to check rear axle alignment.

All that has been done. I did it once to light a smoke.....lesson learnt! Pull up as I have the power to catch up.
I did have one at 140, overtaking 3 road trains with the camper trailer on(it was is first trip). Massive tank slapping, and all I could do is keep powering...160 still going on and then came good. Next stop, reloaded the trailer to shift the weight around.... never had a problem since

Some of the Japanese Sports bike have a steering dampening systems in the head stock (for want of a better word) and I have seen home made steering dampers using the unit from VW Kombi vans on Bikes I haven't checked but you probably can buy an after market unit for most bikes ,I personally never ride no hands and only rarely one handed to flex my fingers and get circulation going in my hands and arms,

Yep!!! I thought I was a goner. I have learnt that 120 is top speed towing the trailer

I can't confirm if she is an actual slapper, in that very English sense of the word, but she is clearly touching the tank..

I read this entire thread and I gotta say, my idea of a tank slapper is way different to all y'alls...

I had the same issues with the original Metz, and the Avon I replaced it with. New Orleans Triumph told me not to let go of the bars.
Second dealership made me change the rear tire. That didn't help, but he wouldn't refund my money for his bad diagnosis.
An old rider told me to just tighten the head bearing 1/8th turn, if that didn't work go 1/4. Well 1/8th turn stopped all of the shaking. Nothing like a free and easy fix.

YES a lot of the mechanics tighten the head bearings to much and that will cause tankslappers
