Head shake on decel

Plow Horse said:

My Roadster did it from day one. On deceleration if you let go of the handle bars when the speed reached 42mph it would start to shake and continue to progressively get worse till 35mph.
As everyone says don’t let go of the handle bars .
At around 8 thousand miles I got it fixed.
No longer has a head shake on decel. I can let go of the handle bars till the bike slows down enough to where it would fall over if I wanted. But I don’t

Mine does not do that. It did the first two years that I owned it but after Replacing the headstock bearings and races I have had no problems at all. Triumph recommends greasing the bearings once a year. How many people do that? Triumph's piss poor excuse for greased bearings at the factory is a joke. I used Lucas Green marine grade grease. Made one minor adjustment after 30,000 miles. Yes while the bike is down I plan on pulling the front end apart and re-grease the bearings. Among other things. Agree on the overtighten the headstock. If you follow the manual on adjustment of the headstock and the wobble comes back after a short time then you just might want to take a good look at your bearings and races. There is nothing wrong with the design or the quality of the headstock. Might be a problem with the type of grease the factory is using if you can even call that slime grease.

keep your hands on the bars till u wear out the front tire then replace tire and it will probably b ok.
every time i get new tire i check holding just a little back from the bars to see if it is going to shake.
that is easier then changing bearings
