But still the bearings did not "cause" the shake, the new bearings just dampened it out.Not for me. Replaced bearings with tapered ones and the vibration went away. Same tires. Same inflation. Tested bike on a road going same said speed and everything. Bike shaking. Did exact same test afterwards. No shake. Bearings don't get loose over time. They wear out. If the bike wasn't shaking once the nut was tightened, then it should never shake. That nut never gets loose unless you installed them wrong. Its got a lock ring on it to prevent that from happening. The real reason the nut appears to be loose and you tighten it some more is the bearing cage is made out of PLASTIC and it wears down!!! Very cheap material. So you tighten it up to take up the slack.
It has everything to do with it. You can only tighten it down so much before it breaks on you. That plastic can only take so much pressure before it gives out.Wing-Rider - the bearing cage just holds the roller elements apart. They have little or nothing really to do with the increasing tolerance issue. Whether made of plastic or metal, doesn't really matter. The bearing races and roller bearing elements themselves are the critical wear items. Unless the races are dimpled/deformed, a retorque (a little tightening) should adjust for slight wear. ... my 25 cents.
The 1800 does not have that type of anti-dive or an adjustment.RIZHACKER.....On the front wheel, both sides, there is a 4 position setting that you change with a screw driver. Haven't got a clue as to what is does. All I know is I experimented with the settings and it is now set on the figure 1, both sides,whereas it was on 3. The shake is completely gone.
Did some internet searching and found that I have adjusted the T.R.A.C. Anti-Dive System. It is now set on the Light anti dive position and it is going to stay therel.
