Stock tire? yes
How many miles? currently 179, did it since new, 2 days ago.
Notice at specific speeds? 30+mph
Always from day one or recent? day one, first time i rode it
Can possibly lift front and check with dial indicator. you can visually see the warble from the tire
Can possibly check out of balance by lifting front and checking gravity rotation. did this numerous times, brake disc is dragging slightly and it must not be out of balance too bad, as it ends up in a different spot every time
Conditions, potholes, curb jumps, skidding stoppies? YES.
it needs a tire, i will get it done eventually i guess. no rush, as i am over the Grom and it will be relugated to the back of the garage now... :smile:
sounds not too bad, suspension light so very noticeable
press the pads back when you check if you can so it doesn't drag.
should be able to hold tire in different places from stopped position and it will roll with heavy point to bottom, not sure spinning will show accurately. Slow and easy, use levels or what you can to ensure good results, lasers, etc., anything available, a popsicle stick mounted to a right angle stand, plumb bob from the ceiling, even a string from a point above to below.
might try breaking the bead, letting out air and rotating the tire for a better balance
a manual tire stand works well. check tire and rim to rule out warpage.
check balance of rim without tire if you're into it that far.
Optional remount of tire with reverse rotation after five hundred more miles, or whenever you want to experiment for better results.
low quality run of the mill tire, eventually just plan for a better tire next time
do more stoppies and keep working it, maybe it won't change
change fork oil to 8w from 5w. maybe to 10w to stiffen stock forks.
note self weight, plus 200, less, more, keep in mind for adjustments, good luck!
