Hi everyone! About a week or two ago i was riding my 99 yz125 in the local sandpit when about halfway through the ride my front end started to feel weird and wobbly. I noticed it after doing a high speed run through the sandpit which is bumpy and does have some rocks...but i dont recall hitting any big rocks or anything out of the ordinary. The best way to describe it...the front wheel seems to sometimes have a mind of its own now...it feels like its wobbling around but when looking at the wheel...its not obviously wobbling. The rim seems to be ok and there doesnt seem to be excessive amounts of wobble to the front tire. To check the front tire i had a friend hold the handle bars as tight as he could with the wheel turned all the way to both sides and i then tried to wiggle the tire...which to me did not feel bad. What other things should i check? The bike always felt nice and tight until that day....i was litterally riding and thought "oh crap did i just get flat tire or something" it suddenly felt so different. Any help insight....like always...is greatly appreciate. Thanks!
